DETAILED DESCRIPTION

An apparatus for parking a vehicle is described that provides automatic parking functionality with enhanced user control and convenience. Implementations described herein enable a driver to select a desired parking space and control the vehicle to automatically park in the desired parking space. In some implementations, the system enables a user to park a vehicle according to a desired position and direction, or to park the vehicle safely away from surrounding objects, or to park the vehicle according to a surrounding environment of the vehicle, such as sunlight or snow.

As such, in some implementations, an apparatus for parking a vehicle enables an accurate interface between the vehicle and a user. The apparatus may provide functionality for the user to select and use various parking methods or parking forms according to situation in addition to a set parking method. In some implementations, the parking apparatus may provide functionality for a user to park a vehicle according to user input even when a parking line is not present.

In addition to automated parking of a vehicle, the apparatus may also automatically change the parking location of a vehicle that has already been parked. For example, the apparatus may move a parked vehicle and re-park the vehicle according to a change in the environment of the vehicle.

A vehicle as described in this disclosure may include a car or a motorcycle, but implementations are not necessarily limited thereto, and may generally include any suitable vehicle that transports people. Hereinafter the description will be based on a car.

The vehicle described in this disclosure may include an internal combustion engine vehicle having an engine as a power source, a hybrid vehicle having an engine, an electric motor as a power source and an electric vehicle having an electric motor as a power source, or generally a vehicle that is motorized by any suitable power source.

In the following description, the left side of a vehicle refers to the left side in a driving direction of the vehicle and the right side of the vehicle refers to the right side in the driving direction of the vehicle.

FIG. 1 shows the exterior of a vehicle according to an implementation.

Referring to FIG. 1, a vehicle 700 may include wheels 103FR, 103FL and 103RR rotating by a power source, a steering unit 721a for steering the vehicle 700 and a plurality of cameras attached to the vehicle 700.

The plurality of cameras may include two or more cameras. While four cameras are described in the following, the present disclosure is not limited to the number of cameras.

According to an implementation, the cameras may include two, three, four or more cameras.

FIG. 2A illustrates the positions of the plurality of cameras according to an implementation.

Referring to FIG. 2A, the plurality of cameras 195a, 195b, 195c and 195d may be respectively arranged at the left, rear, right and front sides of the vehicle.

Particularly, the left camera 195a and the right camera 195c may be respectively provided inside of a case enveloping a left side mirror and inside of a case enveloping a right side mirror.

The rear camera 195b and the front camera 195 may be respectively positioned near a trunk switch and at an emblem or near the emblem.

Images respectively obtained by the cameras 195a, 195b, 195c and 195d may be sent to a processor (170 of FIG. 4A or 4B) included in the vehicle 700. The processor (170 of FIG. 4A or 4B) may generate an around-view image by combining the images. The around-view image may represent a view of a surroundings of the vehicle.

FIG. 2B is a view for explaining an around view image according to an implementation.

Each of the cameras 301a, 301b, 301c, 301d, 301e and 301f may include an image sensor (e.g., CCD or CMOS) and a lens. The cameras 301a, 301b, 301c, 301d, 301e and 301f may acquire images in multiple directions. The acquired images may be sent to the processor 170 and combined by the processor 170.

When the omnidirectional camera module 195 is provided to the vehicle 700, an omnidirectional image with respect to the vehicle 700 may be obtained through the cameras 301a, 301b, 301c, 301d, 301e and 301f. For example, the omnidirectional camera module 195 may acquire images of a front view, a rear view, a left view, a right view, a bottom view and a top view of the vehicle 700.

The number and positions of the cameras 301a, 301b, 301c, 301d, 301e and 301f may be appropriately determined such that an omnidirectional image may be acquired. The cameras 301a, 301b, 301c, 301d, 301e and 301f may have appropriate viewing angles such that images acquired by neighboring cameras may overlap.

The processor 170 may combine all images acquired by the cameras 301a, 301b, 301c, 301d, 301e and 301f on the basis of predetermined features detected from overlapping portions of the acquired images. For example, the processor 170 may detect a common feature from an overlapping portion of a first image acquired by the first camera 301a and a second image acquired by the second camera 301b. The processor 170 may combine the first image and the second image on the basis of the detected feature. In this manner, the processor 170 may generate an omnidirectional image by combining a plurality of images received from the plurality of cameras 301a, 301b, 301c, 301d, 301e and 301f.

The cameras 311a, 312a, 312b, 312c, 312d, 312e and 312f may acquire images in multiple directions. The acquired images may be sent to the processor 170 and combined by the processor 170.

When the omnidirectional camera module 195 is provided to the vehicle 700, an omnidirectional image with respect to the vehicle 700 may be obtained through the cameras 311a, 312a, 312b, 312c, 312d, 312e and 312f.

For example, the first camera 311a from among the plurality of cameras 311a, 312a, 312b, 312c, 312d, 312e and 312f may acquire an image of a top view of the vehicle 700. In this case, it is desirable that the first camera 311a be a wide-angle camera. Cameras 312a, 312b, 312c, 312d, 312e and 312f other than the first camera 311a may acquire images of side views and a bottom view of the vehicle 700.

The image acquired by the first camera 311a may partially overlap with the images acquired by the other cameras 312a, 312b, 312c, 312d, 312e and 312f. The processor 170 may combine the images on the basis of features detected from the overlapping portions.

In addition, the images acquired by the cameras 312a, 312b, 312c, 312d, 312e and 312f other than the first camera 311a may partially overlap. The processor 170 may combine the images on the basis of features detected from the overlapping portions.

The processor 170 may generate an omnidirectional image by combining a plurality of images received from the plurality of cameras 311a, 312a, 312b, 312c, 312d, 312e and 312f.

The processor 170 may acquire a plurality of images from the plurality of cameras 195 and generate an around view image by combining the plurality of images. The processor 170 may display the around view image through the display 180.

The processor 170 may display a parking guide image, which represents a user-specified predicted parking region according to user input, on the around view image. Here, the user input may be touch input applied to the around view image displayed through the display 180. For example, the user input may be touch-and-drag input received through the display 180 while the around view image is displayed. Here, the user input may be referred to as first user input to be discriminated from other user inputs.

The touch-and-drag input may include drag input which connects a touched first point on the around view image and a second point located on horizontal and vertical axes different from the first point without releasing the touch applied to the first point. Here, the parking guide image may have a rectangular form having a line connecting the first point and the second point as a diagonal line.

In this case, the processor 170 may provide a signal for controlling the vehicle to be parked such that the front of the vehicle corresponds to the first point and the back of the vehicle corresponds to the second point.

When a rectangular form having a line connecting the first point and the second point as a diagonal line is formed, the processor 170 may recognize the first point and the second point as directions of the front and back of the vehicle, respectively. The processor 170 may provide a signal for controlling the vehicle to be parked in a recognized direction.

According to an implementation, the first user input may be long touch input received through the display 180 while the around view image is displayed on the display 180. The processor 170 may determine that the touch input is a long touch input, for example, by determining that the touch input has been applied at the same point for a duration that exceeds the threshold. The processor 170 may control the parking guide image to be changed in size in proportion to the duration of the long touch input. For example, the processor 170 may change the size of the parking guide image in response to the duration of long touch input while the shape of the parking guide image is preset.

According to an implementation, the first user input may be input using the mobile terminal 600. For example, the first user input may be input depending on the position and posture of the mobile terminal 600 in contact with or in proximity to the display 180 while the around view image is displayed on the display 180.

The processor 170 may receive information about the position and posture of the mobile terminal 600 through the communication unit 120 while the around view image is displayed. The processor 170 may control the parking guide image to be displayed on the display 180 according to the information about the position and posture of the mobile terminal 600.

When the position and posture of the mobile terminal 600 are changed, the processor 170 may control the parking guide image to be changed according to a degree to which the position and posture of the mobile terminal 600 are changed and to be displayed.

The processor 170 may determine whether the parking guide image is matched to a real parking region. When the parking guide image is matched to a real parking region, the processor 170 may provide a signal for parking control. Here, the signal may be provided to the vehicle-driving unit 750.

The processor 170 may receive user input with respect to the parking guide image while the parking guide image is displayed. Here, the user input may be touch input applied to the parking guide image displayed on the display 180. The user input may be referred to as second user input to be discriminated from other user inputs.

The processor 170 may change the size, direction or shape of the parking guide image according to the second user input. In addition, the processor 170 may control the position of the parking guide image displayed on the around view image to be changed.

The processor 170 may determine whether the parking guide image is matched to an available parking space. The processor 170 may determine whether the parking guide image is matched to a detected available parking space. For example, the processor 170 may determine whether the parking guide image is matched to an available parking space detected from the around view image according to whether the sizes and shapes of the parking guide image and the detected available parking space overlap.

When the parking guide image is matched to the available parking space, the processor 170 may output a parking availability notice through the display 180 or the audio output unit 185.

When the parking guide image is not matched to the available parking space, the processor 170 may output a parking unavailability notice through the display 180 or the audio output unit 185. In this case, the processor 170 may display a recommended parking space. The recommended parking space may be a parking space corresponding to a region closest to the parking guide image, from among available parking spaces. The recommended parking space may be a region having a largest area overlapping the parking guide image, from among the available parking spaces.

The processor 170 may receive user input while the recommended parking space is displayed. Here, the user input may be touch input received through the display 180. The user input may be a parking command. Here, the user input may be referred to as third user input to be discriminated from other user inputs.

Upon reception of the third user input for parking, the processor 170 may provide a control signal for parking.

The processor 170 may control the recommended parking space to be displayed on the around view image displayed on the display 180. Here, the recommended parking space may be determined according to at least one of previous parking experience, detected surrounding environment and a detected object.

For example, the processor 170 may accumulate and store information about a parking space during parking. The processor 170 may calculate a user-preferred parking space on the basis of the stored parking space information. The processor 170 may provide a recommended parking space on the basis of the calculated user-preferable parking space.

For example, the processor 170 may receive surrounding environment information. The processor 170 may provide a recommended parking space on the basis of the surrounding environment information. When the vehicle is parked when it is snowing or raining, the processor 170 may provide a parking space with a roof as a recommended parking space. When the intensity of radiation of sunlight exceeds a reference value, the processor 170 may provide a shaded parking space as a recommended parking space.

For example, the processor 170 may receive information about a neighboring object. The processor 170 may provide a recommended parking space on the basis of the information about the neighboring object. When an expensive vehicle is parked around the vehicle, the processor 170 may provide a parking space at a distance from the expensive neighboring vehicle by a predetermined distance or longer as a recommended parking space such that the vehicle is not parked near the expensive vehicle.

The processor 170 may detect an object located around a parking region. The processor 170 may detect an object located around the parking region by processing an around view image of the vehicle and may calculate a distance between the vehicle and the object. Alternatively, the processor 170 may detect the object located around the parking region through a distance detector (150 of FIG. 4B) and calculate the distance between the vehicle and the object. Alternatively, the processor 170 may detect the object located around the parking region through the cameras which will be described with reference to FIG. 6 and calculate the distance between the vehicle and the object.

When the vehicle is parked according to the parking guide image, the processor 170 may display estimated distances between the vehicle 700 and neighboring objects through the display 180.

Upon calculation of distances between the vehicle 700 and the objects, the processor 170 may provide a signal for controlling a distance between the door at the side of the driver's seat of the vehicle 700 and an object located at the side of the driver's seat to exceed a reference value, thereby securing a space where the driver exits the vehicle.

When the vehicle 700 has been parked, the processor 170 may receive surrounding environment information. The processor 170 may receive information sensed by the sensing unit 760 or information acquired through a communication unit 710 through the interface 130. For example, the processor 170 may receive information about rainfall change, snowfall change, a change in the intensity of sunlight radiated to the vehicle, and the like.

When the surrounding environment changes while the vehicle has been parked, the processor 170 may provide a signal for controlling the parked vehicle to be moved in response to the surrounding environment change. Here, the surrounding environment change may be rainfall change, snowfall change, or change of the intensity of sunlight radiated to the vehicle.

For example, when rainfall or snowfall changes while the vehicle has been parked in an outdoor parking lot, the processor 179 may provide a signal for controlling the parked vehicle to move to an indoor parking lot and park therein.

When the intensity of sunlight radiated to the vehicle exceeds a reference value while the vehicle has been parked in an outdoor parking lot, the processor 170 may provide a signal for controlling the parked vehicle to move to an indoor parking lot and park therein. Otherwise, the processor 170 may provide a signal for controlling the parked vehicle to be move to a shaded parking lot and park there.

Subsequently, the processor 170 may notify the user of completion of movement of the parked vehicle. The processor 170 may transmit parking completion information to the mobile terminal 600 of the user through the communication unit 120. Specifically, the processor 170 may transmit information such as whether the parked vehicle is moved, a parking place, the reason of movement of the parked vehicle, parking time and the like to the mobile terminal 600 of the user.

The display 180 may be implemented such that an image is displayed on the room mirror, the side mirror or the side window glass of the vehicle.

For example, the display 180 may be provided to the room mirror or the side mirror. In this case, the display 180 may usually function as a mirror and display an image when a predetermined event is generated.

For example, the display 180 may be implemented as a transparent display and provided in proximity to the side window glass. Alternatively, the display 180 may include a projection module which projects an image onto the side window glass.

The cameras 195 may acquire an around view image of the vehicle. The cameras 195 include a plurality of cameras which may acquire images at the positions thereof.

For example, the cameras 195 may include a left camera 195a which is provided to the left side of the vehicle 700 and acquires a left view image, a right camera 195c which is provided to the right side of the vehicle 700 and acquires a right view image, a rear camera 195b which is provided to the backside of the vehicle 700 and acquires a rear view image and a front camera 195d which is provided to the front of the vehicle 700 and acquires a front view image. In this case, the left camera 195a, the right camera 195c, the rear camera 195b and the front camera 195d preferably face the ground at a predetermined angle.

It is desirable that the cameras 195 be wide-angle cameras in order to provide an around view image. According to an implementation, the cameras 195 may include fisheye lenses.

According to an implementation, the cameras 195 may process infrared light and visible light together. In this case, the cameras 195 may include a light output unit for outputting infrared light, a beam splitter for splitting received light into infrared light and visible light, a first optical sensor for processing the infrared light and a second optical sensor for processing the visible light. The processor 170 may calculate a distance between the vehicle 700 and an object on the basis of the infrared light.

Referring to FIG. 5A, the processor 170 of the apparatus 100 for parking a vehicle may include an image pre-processor 410, a disparity calculator 420, a segmentation unit 432, an object detector 434, an object verification unit 436, an object tracking unit 440 and an application unit 450.

The image pre-processor 410 may receive a plurality of images or a generated around view image from the plurality of cameras 195a to 195d and pre-process the images or the around view image.

Specifically, the image pre-processor 410 may perform noise reduction, rectification, calibration, color enhancement, color space conversion (CSC), interpolation and camera gain control on the plurality of images or the generated around view image. Accordingly, it is possible to obtain an image clearer than the images acquired by the plurality of cameras 195a to 195d or the generated around view image.

The disparity calculator 420 may receive the plurality of images or the around view image preprocessed by the image preprocessor 410, perform stereo matching on the plurality of images sequentially received for a predetermined time or the generated around view image and obtain a disparity map according to stereo matching. For example, disparity information about the surroundings of the vehicle may be obtained.

Stereo matching may be performed per pixel of the images or in units of predetermined blocks. The disparity map may refer to a map that shows binocular parallax information of images, For example, left and right images, as numerical values.

Specifically, the segmentation unit 432 may separate a background and a foreground from at least one of the images on the basis of the disparity information.

For example, a region having disparity information less than a predetermined value in a disparity map may be calculated as a background and excluded. Accordingly, a foreground may be separated.

As another example, a region having disparity information that exceeds the predetermined value in the disparity map may be calculated as a foreground and extracted. Accordingly, the foreground may be separated.

As described above, a foreground and a background may be separated on the basis of disparity information extracted based on an image so as to increase a signal processing rate and to decrease signal processing quantity during the following object detection.

The object detector 434 may detect an object on the basis of image segments from the segmentation unit 432.

For example, the object detector 434 may detect an object for at least one image on the basis of disparity information.

Specifically, the object detector 434 may detect an object for at least one image. For example, the object detector 434 may detect an object from a foreground separated through image segmentation.

The object detector 434 may receive a plurality of images or a generated around view image and detect objects included in the plurality of images or the generated around view image. The object detector 434 may directly detect objects from the plurality of images or the generated around view image rather than detecting objects for segmented images on the basis of disparity information, distinguished from FIG. 5A.

The object verification unit 436 classifies and verifies detected and separated objects based on image segments from the segmentation unit 432 and the objects detected by the object detector 434.

The disparity calculator 420 of the processor 170 receives the images FR1a and FR1b processed by the image pre-processor 410 and performs stereo matching on the received images FR1a and FR1b to obtain a disparity map 520.

The disparity map 520 represents the binocular parallax between the images FR1a and FR1b as levels. A higher disparity level represents a shorter distance to the vehicle and a lower disparity level represents a longer distance to the vehicle.

The display map may be displayed such that a higher disparity level corresponds to higher luminance and a lower disparity level corresponds to lower luminance.

FIG. 5C shows that first to fourth lanes 528a, 528b, 528c and 528d respectively have disparity levels corresponding thereto and a construction area 522, a first preceding vehicle 524 and a second preceding vehicle respectively have disparity levels corresponding thereto in the disparity map 520.
