The present invention relates to a three-dimensional modeling apparatus for supplying a three-dimensional model of the target based on three-dimensional shape data of a target.
Various types of three-dimensional scanners have been known for years, which can be used to obtain three-dimensional shape data of various types of objects. Engraving machines which are driven based on the three-dimensional shape data are also available. A real three-dimensional model can be produced using such an engraving machine.
A system is known in which three-dimensional shape data of a target such as a person or a statue is obtained by irradiating laser ray on the target and producing the target using the engraving machine.
However, no apparatus for producing a real three-dimensional model and providing the model to a customer is commercially available yet.

A data inputting section 10 captures a target such as a person or the face of a person, and produces an image data. The data inputting section 10 includes a plurality of color CCD cameras, as shown in
The color image data including the color information obtained by the data inputting section 10 is then input to a modeling section 12. The modeling section 12 includes a personal computer or the like, and performs three-dimensional modeling based on the plurality of image data of the target captured at the plurality of positions, to thereby obtain three-dimensional shape data of the target.
The three-dimensional shape data includes the color data of the target. For the three-dimensional modeling, any method can be used such as, for example, the method disclosed in Japanese Patent Laid-Open Publication No. Hei 10-124704.
The obtained three-dimensional shape data is input to a forming section 14. The forming section 14 is, for example, a milling drill which can move with respect to three axis such as xyz, and mills a work to produce a real three-dimensional model based on the input three-dimensional shape data.
The obtained real three-dimensional model is then supplied to a coloring process section 16. The coloring process section is for coloring the real three-dimensional model, and when the target is a person, colors at least the eyes and the mouth.
As described, in this embodiment, the image data is obtained by capturing the target using cameras. Thus, it is safe even when the target is a person. Moreover, color data is obtained for coloring at the coloring process section. Because of this, a real three-dimensional model can be produced which includes color information, and thus, contains unique characteristics.
In the following description, the term “three-dimensional shape data” refers to data on the three-dimensional shape information of the target, and may include the color information. The three-dimensional shape data is obtained by inputting an image at the data inputting section and performing a modeling process at the modeling section. When the data inputting section is a three-dimensional shape measurement device, the three-dimensional shape data may be obtained at the data inputting section. Moreover, data which is obtained by changing, modifying, integrating, and/or processing the obtained three-dimensional shape data is also referred to as the three-dimensional shape data.
The term “real three-dimensional model”, on the other hand, refers to a three-dimensional object produced at the forming section based on the obtained three-dimensional shape data. The “real three-dimensional model” also includes the real three-dimensional model as defined above, colored at the coloring process section.
The term “three-dimensional data” is used interchangeably with the term “three-dimensional shape data” (which may include the color information). A term “pseudo-three-dimensional data”, on the other hand, refers to data which does not contain the three-dimensional shape information of the target but which can display the target in virtual three-dimension. One example of pseudo-three-dimensional data is QuickTime VR data. The term “three-dimensional model” refers to both a real three-dimensional model and to three-dimensional data as defined above.
“Structure of the Data Inputting Section and the Modeling Section”
The data inputting section 10 uses cameras to capture a target. Generally, in order to obtain three-dimensional shape data, a plurality of image data from a plurality of directions are necessary for each immovable target. Therefore, it is preferable to fix a plurality of cameras at predetermined positions to simultaneously capture the target. However, it is also possible to movably mount a camera on a structure such as a rail and obtain a plurality of image data by moving the camera.
The absolute positions of the plurality of the fixed cameras must be precisely determined, but in general this may be difficult with the mechanical means. Therefore, it is preferable to perform calibration of the camera positions by placing a reference object with a predetermined pattern in the camera view and calibrate the camera position based on the image data of the reference object, as shown in
In order to precisely obtain three-dimensional shape data or the like of a target, each of the sections of the target must be seen differently from a plurality of directions. Therefore, it is preferable to project a predetermined pattern on the target using a projector as shown in
When obtaining three-dimensional shape data using such a random pattern, by obtaining depth data by a stereo method using a plurality of cameras, a high precision modeling is possible even for a recess section.
For the camera, it is preferable to use a camera with a wide-angle lens. By using such cameras, the cameras can be placed in relatively small spaces.
The data inputting section 10 captures the target by the cameras and extracts the target area in the image. It is therefore preferable to make the background a constant color to facilitate extraction of the target area in the image.
For example, it is preferable to provide a room with the four walls colored in one color and to place the target at the center of the room. In particular, when the target is a person, it is preferable to place a chair at the center of the room and let the person (target) sit on the chair. When the target is a person, the image captured from the back is usually of less importance.
Therefore, it is preferable to provide an entrance at one wall of the room, have the person sit facing the entrance, and to unify the color of the walls other than the wall with the entrance. It is also preferable to omit the image data from the back when the target is a person.
Furthermore, when the target has a color identical to the background color, extraction can not be performed correctly. Therefore, it is preferable to configure the room so that the background color (the wall color of the room) is changeable. For example, by using a projector, light of a predetermined color can be projected onto the wall, to thereby change its color.
It is also preferable to use at least two colors for the background color, obtain image data with two types of background color, and extract the target area by the union of the extraction results from the two background colors. In this manner, precise extraction of the target area can be accomplished for any target of any color.
It is also preferable to provide lighting apparatuses at the corners of the room for uniform lighting effect on the target and light up the room so that there will be no shadow on the target.
“Structure of the Forming Section”
The forming section 14 produces a real three-dimensional model based on the three-dimensional shape data. As the forming section 14, a milling drill capable of three-dimensional processing can be used, as described before. When the target is the face of a person, a process with only one drill axis direction is also possible. However, in order to precisely process the nostril or the like, it is preferable to use a processing device which can also perform rotation of the drill axis direction.
The material to be used as the basis for the real three-dimensional model includes a scantling and a round bar. However, when the target is known to some extent, for example, when the target is a human face, it is preferable to prepare a template (a prototype of the work to be processed) which resembles the shape of the target and process the template. In this manner, the time required for the process can be reduced. Moreover, various types of templates can be prepared, as shown in
In the example shown in
For the portion corresponding to the hair, it is possible to use a pre-provided template without processing. Specifically, the hair is not usually as important, and it is likely that a template chosen from few types of pre-provided templates is sufficient. Therefore, by preparing few types of templates for the hair portion, it is possible to select and use from among the prepared templates. It is also possible to separately prepare the templates for the hair portion and the templates for the face portion.
In this case, the hair portion can be colored in black. In this manner, coloring process for the hair portion can be omitted. Even when coloring process must be performed, by separately coloring the hair portion, the overall coloring procedure can be simplified. It is preferable that the hair portion is formed so that it is applied to the face portion by covering on the upper section of the face, similar to a wig. It is also possible to form the hair portion as a wig with a thread as the hair.
It is also possible to generate a forming mold and produce a real three-dimensional model using the mold.
It is also possible to create a forming mold by constructing an object with the pin assembly 32, in which the positions of pins 34 are fixed, and the flexible film 30, and generate a real three-dimensional model by filling a material into the forming mold and solidifying the material. By forming a mold in this manner, a plurality of real three-dimensional models can be easily produced.
For example, by using a heat-resistive film as the flexible film 30, a thermosetting resin can be used as the material for formation by heating.
By applying a reset plate 38 from the opposite side of the pin assembly 32, the pins 34 of the pin assembly 32 pushed by the pin 36 can be returned to their original positions and be ready for the next formation. When the shape of the target is known to some extent, such as when the target is a human face, it is also preferable to set the shape of the reset plate 38 into a shape corresponding to a general shape corresponding to the target in order to set the default shape of the pin assembly 32 close to the final shape of the target.
The pins 34 of the pin assembly 34 need not be facing the same direction. It is also possible to set an axial direction for each pin and place the pins according to the set directions, in order to support a curved shape.
In the example shown in
The above configuration is further preferable because a human face resembles a sphere. The shape of the group of heads of the pins 34 need not be shaped into a perfect sphere, and can be any suitable arrangement based on the shape of the target.
With this arrangement, it is also possible to individually determine the positions of the heads of the pins 34 by individually driving the actuators 40, in order to shape the flexible film 30 supported by the pins 34 into a desired shape. Thus, formation of a real three-dimensional model with a desired shape can be achieved.
When forming, instead of using the three-dimensional shape data in its original form, it is also possible to shrink the scale of the three-dimensional shape data along the depth axis and form a real three-dimensional model based on the compressed data. A relief-type real three-dimensional model can be produced. The relief-type real three-dimensional model is easier to form, and the milling waste due to usage of an engraving machine can be reduced.
It is also preferable to extract a characteristic portion of the target and form a model accordingly. For example, by applying an edge exaggerating process on the three-dimensional shape data, the characteristic portion of the three-dimensional shape data can be exaggerated. By producing a real three-dimensional model with the characteristic portion exaggerated, a real three-dimensional model which accurately capture the characteristics of the target can be obtained.
It is also possible to produce the forming mold using clay or the like. In this case, the clay or the like can be recycled.
“Structure of Coloring Process Section”
The coloring process section 16 applies coloring process on the real three-dimensional model according to the color data. Various methods exist for the coloring process, and these methods will be described below.
First, a resist can be applied on the real three-dimensional model and coloring process can be performed using the resist. This method will be described referring to
It is then judged whether coloring process for all the colors are completed (step S14). If not, the procedure returns to step S11 and performs coloring process for the next color. Here, by using a material that repels the paint used for coloring, selective coloring on the portion where the resist is removed is possible. Because the resist is fairly thin, it does not cause a problem even if the portion of the resist which is not removed is left on the model. It is preferable to cover the entire model with a durable protection film after all the coloring processes are completed. In this method, it is better to minimize the number of colors. Accordingly, if the target is a human face, it is preferable to simplify the process to some extent by, for example, coloring the eyes with a black color and lips with a red color.
When the above described coloring method is employed, there is a limit on the number of colors for coloring the target. Therefore, there is a need for a reducing process to reduce the number of colors in the original color data included in the obtained image data. Preferable reduction can be accomplished by, for example, a process with the following steps:
It is also preferable to use a photosensitive agent for the coloring process. This method will be described with reference to
A fixing process is applied to the photosensitive agent to fix the color (step S23). The pattern projection can be achieved, as shown in
It is also possible to directly project a pattern from a CRT on the real three-dimensional model. In this example, the three-dimensional model is a face, and, thus, the exposure is performed with a single irradiation from the front side. In particular, by using a long focal length lens to ensure a sufficient focus depth even for a three-dimensional object, exposure of the entire face portion (hemisphere) can be performed using one projection pattern.
Shrinking the scale along the depth axis for a relief-type real three-dimensional model increases the likelihood of obtaining a uniform exposure. As a photosensitive agent, silver halides such as silver bromide, silver chloride, or silver iodide can be used. These photosensitive agents are applied on the surface of the real three-dimensional model, dried, and then exposed.
Because the real three-dimensional model is a three-dimensional object, there are cases where sufficiently uniform exposure cannot be achieved depending on the direction of the surface. To this end, as shown in
In this case, it is preferable to apply masks so that there will not be too much light incident on an overlapping section from a plurality of projection patterns. In this case, it is preferable to fix the positions of the light source and the projection patterns, and vary the masking based on the real three-dimensional model.
Moreover, it is preferable to remove unnecessary portions after completing all the coloring processes. In other words, as shown in
As shown in
As the heat-shrinkable film, it is preferable to apply a thin coat of a water soluble polymer such as PVA (polyvinyl alcohol) on a film of polyvinyl chloride or fluoride resin, to have a printing capability (print). It is also possible to use an expandable cloth instead of the film.
It is also possible to employ a coloring scheme as described in the following.
For a human face, the main characteristic points lie in the eyes and mouth. Thus, it may be preferable to color only the eyes and mouth. In many cases, the positions of these items, rather than the shape, represent the characteristic point. Thus, as shown in
It is also preferable to prepare a plurality of shapes for the eyes and mouth, select those most closely resembling the target, and use these to color the selected shape. It is also possible to drive a plurality of brushes for each color based on the data for the coloring process.
As shown in
It is also possible to color the real three-dimensional model by an impact dot method using a wire dot and an ink ribbon.
Moreover, it is also preferable, during the coloring procedure, to use a contact pin sensor to detect the surface position of the real three-dimensional model and to color based on the detected position. In this manner, a precise coloring process can be performed, even when the formation precision is insufficient.
It is also possible to transfer using a color processed film.
It is also preferable to layer and bond a plurality of pieces of paper based on the obtained three-dimensional shape data to form a three-dimensional object. In this case, the target shape is first divided by a plurality of parallel planes corresponding to each of the plurality of sheets of paper to be layered and bonded. For example, such a plane can be a plane perpendicular to the y axis (vertical axis) assigned to the three-dimensional shape data.
After printing the color on the cross section between each plane and the target shape on each piece of paper, the cross sections of these pieces of paper are cut, and the pieces are overlapped. A colored three-dimensional object can be formed in this manner.
“Variations”
It may also be preferable to display the three-dimensional shape, including the color, on a display when the three-dimensional shape data is obtained in order to allow a preview of the real three-dimensional model to be produced. When any number of processes described above are applied to compress, exaggerate the characteristic points, and/or limit the colors, it is preferable to show a display which is as close to the final product real three-dimensional model as possible.
It is also preferable to prepare various options and accessories that are different from the actual target, such as, for example, glasses and hair styles, and to permit the mounting of these options on the real three-dimensional model.
For a case of a person, the final real three-dimensional model can be either the head portion only or the complete person. For example, when a complete model is desired, because the face becomes too small, it is preferable to form the model by emphasizing the face by setting the face to body ratio to 1:1. It is also preferable to prepare few such variations, so that a customer is able to select one from among the prepared variations.
When a pet such as a dog is the target, it may be necessary to restrain the pet, such as by using a chain. When it is preferable to provide a chain at the capturing locations, by using the same color for the chain as the background color, extraction of the target from the captured data can be facilitated.
It is preferable to integrate the present invention as a single apparatus and place the integrated apparatus in an arcade or an amusement center. In this manner, a user can enter the apparatus and obtain an image data in the same fashion as taking a picture. After waiting a brief time, the user can obtain a real three-dimensional model doll at the takeout pocket section. A doll of the user can be produced in a similar manner as a picture or a sticker. It is also preferable, when some period of time is required before completion of the production, that a card is issued and the user be able to exchange the card for the produced doll. In this case, the doll for a user can be automatically discharged to the takeout section by reading the issued card by a card reader.
A light projection section 200 projects a random pattern, slit pattern, or coded pattern assigned on a panel 201 onto a target which is a human face. The projected pattern light is reflected at a reflecting section 202 and projected onto the target 203.
An image of the target with the pattern light projected is then captured by an image inputting section 204 such as a CCD camera, and three-dimensional data of the target is produced at a modeling section 205 from the obtained plurality of images by any of the above described methods.
When the distance between the light source of the light projecting section 200 and the target is small and the pattern is directly projected on the target, the target itself produces a shadow, resulting in some portion of the target not projected with the pattern. In other words, there will be portions which cannot be seen from the light source (dead angle). In a case shown in
Thus, the shape measurement of these portions will be difficult or inaccurate.
One solution for preventing such possibility of a dead angle is to set the distance between the light source and the target sufficiently large, as shown in
Thus, a reflecting section 202 is provided to reflect the projection pattern and project onto the target.
By employing such a method, the light path distance from the light projection section 200 to the target can be set at a large distance while the size of the overall apparatus is kept from becoming large.
It is also possible to irradiate a laser ray, other than the pattern light as described above, from the light projection section 200. A laser ray irradiating device generally has a structure such as shown in
Specifically, in
In
However, even in these cases, when the distance to the target is insufficient, there will be problems associated with the produced dead angle. Therefore, setting the light path distance large using a reflecting section is again an effective method for reducing the dead angle.
The problem of dead angle, on the other hand, is similarly generated when an object on which the pattern is projected is input. For example, as shown in
Thus, the camera captures an image of the pattern projected target as reflected at the reflecting section. In this manner, the distance from the target to the camera can be set at a large distance thereby reducing the dead angles, while simultaneously the size of the overall apparatus is kept small.
A plurality of data inputting sections 240 for capturing a target from a plurality of directions and inputting the image data are included. The data inputting sections 240 include an image inputting section 241. As the image inputting section 241, an analog or digital color CCD camera or the like can be used.
Some of the data inputting sections have a data input reference parameter determining section 242 for determining suitable values for the parameters such as white balance and exposure during the data input process.
The other data inputting sections, on the other hand, include a parameter setting section 243 for setting the parameters to those determined at the data input reference parameter determining section 242. At these data inputting sections, image input is performed based on the set parameter.
At the modeling section 244, three-dimensional shape data of the target is calculated based on a plurality of images obtained at the data inputting sections. The modeling process can be, for example, the method disclosed in Japanese Patent Laid-Open Publication No. Hei 10-124704.
The data input flow will next be described referring to
Parameters such as white balance and exposure are automatically determined at a data inputting section (step S10). This can be easily accomplished by automatic white balance and/or automatic exposure functions provided on a common camera.
The determined parameters are then notified to the other data inputting sections (step S11).
At each of the data inputting sections, the notified parameters are set at the parameter setting section within each of the data inputting sections (step S12). In other words, at these data inputting sections, the parameters are not automatically determined at the respective inputting sections, but, rather, the parameters are set as notified from outside.
An image is then input at all of the data inputting sections based on the set parameter (step S13).
In this manner, by using the parameter determined at one data inputting section as a common parameter, and inputting the image at all the data inputting sections based on the common parameter, images of uniform quality can be obtained.
If, on the other hand, the parameters are individually set at each of the data inputting section to suit the individual views, different parameters will be set as the suitable parameter because (a) the portion of the target which can be seen from the inputting sections are different and (b) the background (portion other than the target) which can be seen from the inputting sections are different.
Because of this, colors for the same element, which should, of course, be identical, actually differ for each of the data input sections, leading to a problem when one unified three-dimensional shape data is generated. However, by determining a reference parameter and using the reference parameter as a common parameter, image input is enabled which satisfies the condition that the color for the same element should be identical.
Here, a case is shown where the reference parameter is automatically determined at one data inputting section, but the reference parameter can also be determined by an operator. There are some cases where an experienced operator wishes to set a suitable parameter value different from the value automatically determined by the data inputting section, based on his experience or when he wishes to have a special effect. In such a case, it is preferable to manually set the reference parameters.
Although in the above example three-dimensional shape data of the target is created, the method can also be applied where it is desired to create pseudo-three-dimensional data, such as QuickTime VR data, of the target. By using the method of the present invention, the problem of colors changing when the target is rotated and displayed can be avoided.
When a real three-dimensional model is created by inputting a person's face or body and forming a model for providing to a customer as described above, a certain amount of time is required between the inputting process and completion of the model formation. When such a three-dimensional modeling apparatus is to be placed in, for example, an arcade, it may be preferable to employ the following embodiment. The description will be for a case where a human face is input.
The three-dimensional modeling apparatus comprises an inputting section for inputting data and a forming section. These sections can be integrated together, or, alternatively, can be connected by a network as shown in
While the customer waits for the completion of the model, they are enticed to use other game machines. It is preferable to allow the customer to use the issued memory card by letting the other machine read the contents of the memory card and using the recorded three-dimensional shape data for display or for replacing a character within the game. While conventional game machines only allow for input of the name when a new point record is made, with the present apparatus, it is possible and preferable to display the three-dimensional shape data stored in the memory card along with the point record. In this manner, a customer can enjoy their waiting time and the likelihood of customer dissatisfaction is reduced.
It is also preferable to allow for additional recording on the memory card for the game points at the other game machines. By determining size, coloring parameters, or number of products of the real three-dimensional model to be formed based on the recorded points, it is possible to encourage the customer to use more game machines.
In this case, the formation process must be started by a start command such as the customer inserting the memory card into the forming device.
Moreover, when the game machines within an arcade are interconnected by a network, it is preferable to store only the identification number in the memory card and to distribute the three-dimensional shape data to each of the game machines via the network. Alternatively, it is possible to issue an identification number of a customer when he inputs the face data, and let the customer input the identification number at each game machine so that there is no need for a memory card. Specifically, the identification number can be an electrical mail address or a phone number for a portable phone, both of which may be input by the customer, or the total sequence number of the customer counted from the start of the business.
It is also important to notify the customer when the actual formation process has been completed. When the game machines within an arcade are connected via a network, it is preferable to display a message notifying the customer of the completion of the model formation on a game machine that the customer is using at that time. In consideration of a case where the customer is not using a game machine, it is also preferable to separately provide a display panel (completion display panel 260) within the arcade for displaying the identification number for models that have been completed.
In addition to the above, it is preferable that the phone number for a portable phone belonging to the person requesting the model be input along with the face data, and to set the apparatus so that it notifies the customer by calling their portable phone when the formation is complete. It is possible to notify the completion by sending an electrical mail to a portable phone 261 or a portable terminal with an electrical mail capability.
In addition, it is also preferable to display, when inputting the face data, the earliest time when the real three-dimensional model formation can be completed, to allow the customer to specify a desired time after the earliest time, and to start the formation of the model to follow the specified schedule. In this manner, the customer can predict when the real three-dimensional model will be available and can obtain the model at the desired time.
When game points earned at other game machines affect the resulting real three-dimensional model as described above, it is preferable to set the apparatus so that the formation starting time is pre-specified when the face data is input and that the points obtained prior to the starting time affect the resulting real three-dimensional model.
For a customer who wishes to obtain three-dimensional shape data but does not require a real three-dimensional model, it is also preferable that the three-dimensional shape data be sent via electronic mail after the face data is input. Alternatively, it is also preferable that the three-dimensional shape data be saved on a server and that an electronic mail be sent to provide identification information for accessing the server. In the latter case, the customer accesses the server by ftp or via the web when the data becomes necessary, inputs the sent identification number, and downloads the desired data.
It is also preferable that a delivery destination address be input along with the face data, and, when the real three-dimensional model is formed, to print and output the address for directly delivering the real three-dimensional model. After the forming process, the created real three-dimensional model can be packed, the printed and output delivery destination label can be affixed on the package, and the package can be transferred to a suitable delivery agent, allowing for a very easy delivery procedure. When a plurality of forming sections are present in a wide area through a network, it may be preferable to transmit the three-dimensional shape data to a forming device that is logistically convenient or geographically close based on the delivery destination address, to form the model at the selected forming device, and to deliver the model to the specified delivery destination. By employing such a method, the time and cost for delivery of the real three-dimensional model to the customer can both be reduced.
When the real three-dimensional model is formed, rather than forming only the face which has been input, by forming a plurality of faces or by forming a face with other accessories, an added-value can be obtained. For this purpose, the three-dimensional modeling apparatus is connected to a database via a network. In the database, pre-stored three-dimensional shape data for celebrities, CG synthesized three-dimensional shape data for animation heroes, or three-dimensional shape data of friends of the customer, and the three-dimensional shape data for accessories such as glasses and earrings are stored and managed.
The three-dimensional modeling apparatus further comprises a user interface section. The customer can view various data registered in the database and specify desired data via the user interface section. The specified data is integrated with the three-dimensional shape data of the customer himself, and the generation of the real three-dimensional model is performed at the forming section. With the above procedure, it is possible for the customer to obtain a virtual real three-dimensional model such as, for example, a model in which the customer and a celebrity are together. It is also possible to generate a virtual real three-dimensional model where the model wears ornaments that the customer does not actually wear.
Many of such three-dimensional modeling apparatuses comprise a plurality of forming devices rather than only one forming device. The plurality of forming devices can either have identical specifications or different specifications. As different specification, various cases can be considered, such as, for example, different size of three-dimensional models that can be formed, different materials for the forming object, or different method of forming, such as, for example one unit employing a milling method and one based on 3D lithography type, for example).
When a plurality of forming devices are connected, it is preferable to schedule these apparatuses. Specifically, a scheduling section comprises a calculator such as a computer, and manages the processing progress at each of the connected forming devices and information on the data which is waiting to be processed. Also, each of the forming devices may store information on the average completion time for formation for each set of three-dimensional shape data.
The three-dimensional shape data, after the modeling process at the modeling section, is sent to the scheduling section. Based on the operational conditions of each of the forming devices, the data is transmitted to a suitable forming device. Here, a suitable device would normally be the forming device with the shortest wait time for the process. It is possible for a customer to specify parameters for formation such as the formation size or the like at the user interface section. In this case, the scheduling section may, instead of strictly selecting the device with the shortest wait time, may select a device with the shortest wait time from among devices that satisfy the user specified parameters.
It may not in all instances be desired that the data input and the formation start be close. For example, in an application for preparing a statue of deceased for funeral use, it is preferable that the data be input while the customer is still alive and then be stored in a server. A formation request will be made when the statue is needed, and the formation will then be started at that point.
Thus, in this case, a plurality of data, in actuality, an enormous amount of data, must be stored in the server. It is possible to send the formation request electronically, such as via an electronic mail, and the forming section also accepts the delivery destination for delivering the product, in addition to the formation request.
An apparatus for supplying a real three-dimensional model to a customer by automatically performing processes from three-dimensional input till the formation has been described. Next, a method for supplying a real three-dimensional model to a customer after coloring the formed real three-dimensional model will be described.
The coloring process may be performed automatically as described before. Here, however, an example will be described wherein the coloring process is manually performed in order to allow for more flexible coloring to satisfy the customer's wishes. An example of this case includes a memorial doll production for family events such as a wedding or a funeral. Specifically, the case includes production of “May Dolls” resembling a child, production of dolls of a bride and groom for a wedding, and production of a doll of the deceased to be displayed at a funeral.
The uncolored real three-dimensional model, created by the real three-dimensional modeling apparatus as described above, is sent for coloring process, which may be performed manually by a coloring craftsman. The coloring craftsmen color the real three-dimensional model, and the colored real three-dimensional model will be delivered to the customer.
In order to efficiently complete such coloring procedure by coloring craftsmen, it is preferable to perform the coloring operation while viewing the three-dimensional data from an specified angle. For this purpose, in the coloring step, the three-dimensional shape data is sent along with the real three-dimensional model to be colored. This further requires a display apparatus for displaying the object from an arbitrary view point based on the sent three-dimensional shape data.
The display apparatus corresponds to, for example, a display of a personal computer. The personal computer temporarily stores the received three-dimensional shape data, generates an image from an arbitrary point of view based on this data and according to a direction given by the coloring craftsman, and displays an image on the display. Preferably, the display is one capable of a three-dimensional display including stereo-scopic display. Specifically, examples of the display apparatus includes a three-dimensional display using a liquid crystal shutter or changing glasses and a three-dimensional display of no-glass type with a lenticular lens or a parallax barrier.
It is desirable that the real three-dimensional model is directly delivered to the customer after the coloring procedure is completed. For this purpose, it is possible for a customer to input a desired delivery destination via the user interface included in the inputting section. The delivery destination is printed on a label and sent to the coloring craftsman along with the real three-dimensional model to be colored. The data can also be sent to the coloring craftsman via a network and can be printed on the label by the coloring craftsman.
It is also preferable that a plurality of coloring craftsmen exist with their schedules managed as described before.
When such a real three-dimensional model is generated, it is also possible to use a component formed based on the individual input data only for the head portion, and to combine the created head component with a pre-formed body component. In general, a characteristic of a person appears mostly in the head (face) portion. Therefore, by using a common component for the less-distinctive body section, production costs can be reduced. For example, the pre-provided component can be a body section of a commercially available doll. In such a case, it is preferable to provide a component, referred to as a neck component, for incorporating the head component with the following characteristics for incorporating an individually prepared head component to a body component.
In other words, as shown in
In addition to the above, it is also preferable to provide the three-dimensional shape data itself without creating a real object model based on the input three-dimensional shape data. Specific examples of this application include a dating agency and three-dimensional goods catalog for the Internet.
When providing data in a field such as a dating agency, it is preferable that a restriction be applied for data access and for display point of view. In other words, only the registered members are allowed to access the data and only a display from a display view point that is permitted by the person who provided the three-dimensional shape data is allowed. The restriction is particularly important for the latter case, because in general, there is a view point that a person do not wish others to see from (such as, for example, view point at the bottom viewing toward top).
It is also preferable to distinguish the guest users and the registered members on the range of allowed view points that can be chosen. In this manner, incentive to join the members can be increased.
It is also preferable for a plurality of data for various facial expressions to be input when inputting the data for one person, and to sequentially display three-dimensional shape data with a plurality of facial expressions according to a request from a viewer. Particularly, by using common data for the body portion of a person and displaying the plurality of face expressions by only replacing the head portion, three-dimensional display of a plurality of facial expression data for the person can be preformed quickly.
In addition to the above, it is also preferable that voice data be along with the three-dimensional shape data. By combining the voice with the three-dimensional shape data, the data can be displayed with the voice. With current computer graphics technology, it is possible to alter the three-dimensional shape data of a face to move the mouth to correspond to the voice to create an appearance that the three-dimensional display is speaking, and such a display is also preferable.
Compared to the total volume of all three-dimensional shape data used by, for example, a dating agency, in the application for a three-dimensional product catalog on the Internet, an enormous a amount of data must be managed. Therefore, there is a need to select a certain items from the enormous amount of data for display to a customer. For this purpose, the it is preferable that the three-dimensional modeling apparatus access a database system.
As shown in
It is preferable that, in addition to the three-dimensional shape data itself, a thumbnail image of the data also be managed by the database. This is preferable because there is a demand for a customer to view the general image of an item by a thumbnail image after the customer has narrowed down from the items registered in the database based on specific keywords. Examples of methods for generating a thumbnail image include:
When undetermined access to the data via a network is made possible, it may be preferable to employ a system where the number of accesses to each data is recorded and charges are determined based on the recorded data. The database has information on the charge/refund subject related to each data. The number of accesses for the data are collected every month and charge/refund processes are executed for the charge/refund subject according to the number of accesses. In a case of a product catalog, a method can be considered where a greater charge is associated with items with more accesses, because the number of accesses indicate that significant advertising effect was presented. On the other hand, there is another system where a predetermined amount of money is paid to the supplier of the data system when registering to the database, and wherein this amount increases the amount of refund with an increase in the number of accesses. The latter case is based on a concept that data which utilizes the storing space, but is not accessed should be penalized. In some cases, the refund may be considered as a bounty.
In the above, various examples are described. In any of the cases for supplying the three-dimensional shape data, usage of a three-dimensional display apparatus as the display side is preferable. A three-dimensional display apparatus is one of the most suited apparatus for displaying three-dimensional shape data. It is effective to input voice with the three-dimensional shape data and to input three-dimensional movement information along with the shape information. Because human body movements are produced at the joints, it is possible to divide the input three-dimensional shape data into parts at the joint sections. By recording the relative movement information for each of the parts, movement information can effectively be recorded. When preparing a three-dimensional image for the customer, the three-dimensional image can be shown efficiently by displaying the motion of the three-dimensional shape data so that the display moves part-by-part based on the input movement data.
As described above, according to the present invention, a practical system for effectively and efficiently providing automatically generated real three-dimensional model and three-dimensional shape data to a customer can be realized.
