The present disclosure relates to an automated photography station, and more particularly, to an automated photography and inspection station operable to properly visualize different types of objects, and operable to determine characteristics of an object. The present disclosure also relates to methods of photographing and/or inspecting an object.
Photography systems and methods have traditionally used multiple, manually operated cameras to take individual photographs of stationary objects. To photograph these stationary objects from different vantage points, the stationary objects and/or the cameras are manually rotated, and multiple photographs are taken at each stationary position to completely visualize the object. Due to the manual nature of these traditional systems and methods, photographic blind spots can occur, and similar objects are not visualized in a consistent manner due to manually controlled camera inconsistencies and rotation inconsistencies. In addition, traditional photography systems and methods did not offer configuration options to enable proper visualization of different types of objects.
The present disclosure is directed to an automated photography and inspection station and methods of operation.
In an implementation, the automated station is computer controlled and fully configurable to enable proper photographic visualization of different types of objects, such as jewelry, clothing, and industrial equipment, for example.
In an implementation, the automated station is operable to inspect and determine characteristics of an object. In some implementations, the automated station is operable to measure dimensions of an object to determine its nominal size, length, width, height, diameter, and thickness, for example. In some implementations, the automated station is operable to take light-related measurements to determine characteristics of a gemstone. In some implementations, the determined characteristics of the gemstone include the gemstone type and whether the gemstone is real or synthetic.
In another implementation, the present disclosure is directed to an automated method of photographing objects. The method may comprise receiving an object into a computer-controlled automated station, receiving information about the object, automatically adjusting one or more configuration options of the automated station based on the information about the object, and taking one or more photographs of the object. In some implementations, the one or more configuration options include adjustable lighting features, adjustable camera features, and adjustable turntable features.
In yet another implementation, the present disclosure is directed to an automated method of inspecting objects. The method may comprise receiving an object into a computer-controlled automated station, receiving information about the object, automatically adjusting one or more configuration options of the automated status based on the information about the object, and inspecting the object. In some implementations, the method further comprises positioning an object onto a tray with known dimensions and receiving the object on the tray into the computer-controlled automated station. In some implementations, the method further comprises taking one or more photographs of the object on the tray, and using the photographs to determine measurements of the object by comparison with the known dimensions of the tray. In some implementations, the known dimensions of the tray include a length, a width, and a height of the tray. In some implementations, the known dimensions of the tray include one or more circles of a specific diameter printed on a base surface of the tray.
Another automated method of inspecting objects may comprise positioning a gemstone within a computer-controlled automated station, using a camera to measure a reflectivity of light coming off the gemstone, using a refractometer to measure a refractive index of light coming off the gemstone, and determining characteristics of the gemstone type based on the measurements. In some implementations, the determined characteristics of the gemstone include the gemstone type and whether the gemstone is real or synthetic.
The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the implementations will be apparent from the description and drawings.
For a more complete understanding of this disclosure and its features, reference is now made to the following description, taken in conjunction with the accompanying drawings, in which:
Like reference symbols in the various drawings indicate like elements.
The present disclosure is directed to an automated photography and inspection station and methods of operation. In an implementation, the automated station is computer controlled and fully configurable to enable proper photographic visualization of different types of objects. In an implementation, the automated station is further operable to inspect and determine characteristics of an object.
To fully visualize an object, the automated station may include multiple, independently configurable cameras, multiple independently configurable light fixtures, and a turntable that may remain stationary or may rotate based on configurable parameters. Thus, the automated station allows for computer control of cameras, light fixtures, and a turntable during operation. The automated station also provides rapid object visualization by leveraging multiple cameras documenting the same viewing area, and it produces consistent visualization of like objects. Photographic images taken by the automated station may be stored locally and may be made available immediately after capture.
The automated station may further be operable to inspect and determine characteristics of an object. In some implementations, the automated station is operable to measure dimensions of an object to determine its nominal size, length, width, height, diameter, and thickness, for example. The automated station may include additional sensors and measurement devices, such as scales to measure the weight of an object, or a refractometer to measure a refractive index of light from an object. The automated station may further be operable to take light-related measurements to determine characteristics of a gemstone. In some implementations, the determined characteristics of the gemstone include the gemstone type and whether the gemstone is real or synthetic.
The automated station may be accessed and controlled through a data processing system that enables a user to interact with the automated station via direct interaction with the hardware, via a custom software solution, through onboard firmware commands, and/or through an onboard API. For example, each automated station camera and light fixture configuration can be set manually, through direct interaction with the custom software, through a configuration file in the onboard firmware, or through parameters passed via the API.
The automated station software may provide automatic image cropping to maximize visualization of a region of interest of the photographed object. The automated station software may further allow for full configuration of the number of images taken, image selection and resolution, and physical operation controls. The automated station software may allow for full control of the speed of object rotation on the turntable.
Referring now to the drawings, where like reference numerals represent like components,
The front panel 110 includes an opening 115 to provide a user access to the interior of the automated station 100 where an implementation of a turntable 200 is shown positioned on an interior floor 165 of the automated station 100. The turntable 200 may include a base 210, a large platform 220, and a raised, smaller platform 230 that forms a stacked configuration. In some implementations, at least one of the platforms 220, 230 is motorized and operable to rotate at a configurable rotation speed. Thus, during operation of the automated station 100, the platforms 220, 230 of the turntable 200 may be stationary or rotating at a user's election, and the automated station 100 enables automated rotation based on configurable parameters.

In some implementations, the automated station 100 of the present disclosure comprises a fixed camera mounted to the top panel 150 and a plurality of cameras supported by adjustable camera mounts on the side panels 120, 130 and/or the back panel 140 of the automated station 100. In some implementations, one camera is positioned on each of the side panels 120, 130 and on the back panel 140. The automated station 100 may further include multiple, independently configurable light fixtures. This allows for simultaneous and/or sequential photographs to be taken of an object that is positioned within the viewing area, such as on the turntable 200.
With reference now to
Processor unit 404 serves to execute instructions for software that can be loaded into memory 406. Processor unit 404 includes one or more processors. For example, processor unit 404 can be selected from at least one of a multicore processor, a central processing unit (CPU), a graphics processing unit (GPU), a physics processing unit (PPU), a digital signal processor (DSP), a network processor, or some other suitable type of processor. For example, processor unit 404 may be implemented using one or more heterogeneous processor systems in which a main processor is present with secondary processors on a single chip. As another illustrative example, processor unit 404 can be a symmetric multi-processor system containing multiple processors of the same type on a single chip.
Memory 406 and persistent storage 408 are examples of storage devices 416. A storage device is any piece of hardware that is capable of storing information, such as, for example, without limitation, at least one of data, program code in functional form, or other suitable information either on a temporary basis, a permanent basis, or both on a temporary basis and a permanent basis. Storage devices 416 may also be referred to as computer-readable storage devices in these illustrative examples. Memory 406 in these examples can be, for example, a random-access memory or any other suitable volatile or non-volatile storage device.
Persistent storage 408 may take various forms, depending on particular implementations. For example, persistent storage 408 may contain one or more components or devices. For example, persistent storage 408 can be a hard drive, a solid-state drive (SSD), a flash memory, a rewritable optical disk, a rewritable magnetic tape, or some combination thereof. The media used by persistent storage 408 also can be removable. For example, a removable hard drive can be used for persistent storage 408.
Communications unit 410, in these illustrative examples, provides for communications with other data processing systems or devices. In these illustrative examples, communications unit 410 is a network interface card.
Input/output unit 412 allows for input and output of data with other devices that can be connected to data processing system 400. For example, input/output unit 412 may provide a connection for user input through at least one of a keyboard, a mouse, or some other suitable input device. Display 414 provides a mechanism to display information to a user.
Instructions for at least one of the operating systems, applications, or programs can be located in storage devices 416, which are in communication with processor unit 404 through communications framework 402. The processes of different examples can be performed by processor unit 404 using computer-implemented instructions, which may be located in a memory, such as memory 406.
These instructions are referred to as program code, computer usable program code, or computer-readable program code that can be read and executed by a processor in processor unit 404. The program code in the different examples can be embodied on different physical or computer-readable storage media, such as memory 406 or persistent storage 408.
Program code 418 is located in a functional form on computer-readable media 420 that is selectively removable and can be loaded onto or transferred to data processing system 400 for execution by processor unit 404. Program code 418 and computer-readable media 420 form computer program product 422 in these illustrative examples. In the illustrative example, computer-readable media 420 is computer-readable storage media 424.
In these illustrative examples, computer-readable storage media 424 is a physical or tangible storage device used to store program code 418 rather than a medium that propagates or transmits program code 418.
Computer-readable signal media 426 may be, for example, a propagated data signal containing program code 418. For example, computer-readable signal media 426 may be at least one of an electromagnetic signal, an optical signal, or any other suitable type of signal. These signals may be transmitted over at least one of communications links, such as wireless communications links, optical fiber cable, coaxial cable, a wire, or any other suitable type of communications link.
Further, as used herein, “computer-readable media” can be singular or plural. For example, program code 418 can be located in computer-readable media 420 in the form of a single storage device or system. In another example, program code 418 can be located in computer-readable media 420 that is distributed in multiple data processing systems. In other words, some instructions in program code 418 can be located in one data processing system while other instructions in in program code 418 can be located in one data processing system. For example, a portion of program code 418 can be located in computer-readable media 420 in a server computer, while another portion of program code 418 can be located in computer-readable media 420 located in a set of client computers.
In an implementation, the present disclosure is further directed to an automated method of photographing and/or inspecting objects. Referring now to
If the input received at Step 550 indicates the automated station will perform both the photography and inspection operations, the method will proceed along path A where one or more photographs of the object will be taken at Step 560, and the method will proceed along path B where the object will be inspected at Step 570, before proceeding along path C to end the method at Step 580.
If the input received at Step 550 indicates the automated station will only perform the photography operation, the method will proceed along path A where one or more photographs of the object will be taken at Step 560, before proceeding along path C to end the method at Step 580.
If the input received at Step 550 indicates the automated station will only perform the inspection operation, the method will proceed along path E to inspect the object at Step 570, before proceeding along path C to end the method at Step 580.
In some implementations of the method 500, receiving information about the object at Step 530 may include receiving information about the type of object. For example, if the automated station is configured to photograph and inspect jewelry, a user may provide information at Step 530 that the object is a ring, a necklace, a bracelet, a watch, or a loose gemstone.
In some implementations of the method 500, the configuration options of the automated station adjusted at Step 540 may include adjustable lighting features, adjustable camera features, and adjustable turntable features. In some implementations, the adjustable lighting features may include the number and location of the light fixtures to be illuminated, the brightness of the illumination of each light fixture, and the angular orientation of each light fixture. In some implementations, the adjustable camera features may include the number and location of the cameras that will capture images of the object, the focus of each cameras, the number of images captured by each camera, and the angular orientation of each camera. In some implementations, the adjustable turntable features may include whether the turntable platform is stationary or rotating, and the speed of turntable platform rotation.
In some implementations, the method 500 may further comprise positioning an object onto a tray with known dimensions and receiving the object on the tray into the computer-controlled automated station at Step 520.
In some implementations, a method of inspecting an object further comprises taking one or more photographs of the object on the tray 250, and using the photographs to determine measurements of the object by comparison with known dimensions of the tray.
For example, if the automated station is configured to photograph and inspect jewelry, a user may provide information at Step 530 that the object is a ring, and the method of inspecting the ring may include determining one or more of the nominal ring size, the wall thickness of the ring, and the height of the ring. To do so, a diameter of the ring opening may be compared to the surface pattern 260 of concentric circles, each with a known diameter. In some implementations, the innermost circle of the surface pattern 260 corresponds with a size 7 nominal ring size. In addition, a wall thickness of the ring can similarly be determined using an outer diameter of the ring. Further, a height of the ring can be determined based on how much of the camera frame is filled up by the ring.
As another example, a user may provide information at Step 530 that the object is a bracelet or a necklace in the form of a chain, and the method of inspecting may include determining a length of the chain. To do so, the chain may be formed into a circle such that a diameter of the chain circle may be compared to the surface pattern 260 of concentric circles, each with a known diameter. Alternatively, the chain may be criss-crossed over the surface of the tray 250, and the lengths of each span of chain may be added up to determine a total length. Typically, bracelets are sold in nominal lengths such as 7-inch and 8-inch lengths, and necklaces are sold in nominal lengths such as 16-inch, 18-inch, 20-inch, 24-inch and 30-inch lengths.
In some implementations, a method of inspecting an object may comprise positioning a gemstone within a computer-controlled automated station, using one or more cameras within the automated station to measure a reflectivity of light coming off the gemstone, using a refractometer to measure a refractive index of light coming off the gemstone, comparing the measured refractive index to a database of known refractive indices for gemstones, and determining characteristics of the gemstone type based on the measured reflectivity and refractive index. In some implementations, the determined characteristics of the gemstone include the gemstone type and whether the gemstone is real or synthetic. In some implementations, the determined characteristics are verified to the computer controller for machine learning purposes. The method of inspecting a gemstone may be very sensitive such that the automated station can detect different types of gemstones of the same color.
The automated photography and inspection station and methods of operation of the present disclosure provide a more efficient and more accurate way to photograph and inspect an object as compared to a manual process. In an implementation, a piece of jewelry can be photographed, sized, measured, and a gemstone type can be determined in less than 60 seconds. The automated photography and inspection station and methods of operation enable jewelers and other repair service providers to photographically capture an object accurately upon intake as well as after repairs have been made to verify that repairs have been done properly.
