    RELATED APPLICATIONS
  • This application claims priority to U.S. application Ser. No. 61/650,983, entitled SYSTEMS AND METHODS TO VIRTUALLY TRY-ON PRODUCTS, filed on May 23, 2012; and U.S. application Ser. No. 61/735,951, entitled SYSTEMS AND METHODS TO VIRTUALLY TRY-ON PRODUCTS, filed on Jan. 2, 2013, both of which are incorporated herein in their entirety by this reference.
  • BACKGROUND
  • The use of computer systems and computer-related technologies continues to increase at a rapid pace. This increased use of computer systems has influenced the advances made to computer-related technologies. Indeed, computer systems have increasingly become an integral part of the business world and the activities of individual consumers. Computers have opened up an entire industry of internet shopping. In many ways, online shopping has changed the way consumers purchase products. For example, a consumer may want to know what they will look like in and/or with a product. On the webpage of a certain product, a photograph of a model with the particular product may be shown. However, users may want to see more accurate depictions of themselves in relation to various products.
  • SUMMARY
  • According to at least one embodiment, a computer-implemented method for generating a three-dimensional (3-D) model of a user is described. A plurality of images of a user may be obtained. An angle of view relative to the user pictured in at least one of the plurality of images may be calculated. It may be determined whether the calculated angle of view matches a predetermined viewing angle. The predetermined viewing angle may include a plurality of evenly spaced 10-degree rotation steps. Upon determining the calculated angle of view matches the predetermined viewing angle, at least one of the plurality of images may be selected.
  • In one embodiment, a real-time image of the user may be displayed while obtaining the plurality of images of the user. A guideline may be displayed in relation to the displayed real-time image of the user. A cross-correlation algorithm may be performed to track a feature between two or more of the plurality of images of the user. A 3-D model of the user may be generated from the detected features of the user. Texture coordinate information may be generated from the determined 3-D structure of the user. The texture coordinate information may relate a two-dimensional (2-D) coordinate of each selected image to a 3-D coordinate of the 3-D model of the user. At least one geometry file may be generated to store data related to a 3-D structure, wherein each at least one geometry file comprises a plurality of vertices corresponding to a universal morphable model.
  • In some configurations, a coefficient may be calculated for each generated geometry file based on the determined 3-D structure of the user. Each generated geometry file may be combined linearly based on each calculated coefficient to generate a polygon mesh of the user. Each selected image may be applied to the generated polygon mesh of the user according to the generated texture coordinate information.
  • A computing device configured to generate a three-dimensional (3-D) model of a user is also described. The device may include a processor and memory in electronic communication with the processor. The memory may store instructions that are executable by the processor to obtain a plurality of images of a user, calculate an angle of view relative to the user pictured in at least one of the plurality of images, determine whether the calculated angle of view matches a predetermined viewing angle, and upon determining the calculated angle of view matches the predetermined viewing angle, select at least one of the plurality of images.
  • A computer-program product to generate a three-dimensional (3-D) model of a user is also described. The computer-program product may include a non-transitory computer-readable medium that stores instructions. The instructions may be executable by a processor to obtain a plurality of images of a user, calculate an angle of view relative to the user pictured in at least one of the plurality of images, determine whether the calculated angle of view matches a predetermined viewing angle, and upon determining the calculated angle of view matches the predetermined viewing angle, select at least one of the plurality of images.

  • DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
  • The systems and methods described herein relate to the virtually trying-on of products. Three-dimensional (3-D) computer graphics are graphics that use a 3-D representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering two-dimensional (2-D) images. Such images may be stored for viewing later or displayed in real-time. A 3-D space may include a mathematical representation of a 3-D surface of an object. A 3-D model may be contained within a graphical data file. A 3-D model may represent a 3-D object using a collection of points in 3-D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3-D models may be created by hand, algorithmically (procedural modeling), or scanned such as with a laser scanner. A 3-D model may be displayed visually as a two-dimensional image through a process called 3-D rendering, or used in non-graphical computer simulations and calculations. In some cases, the 3-D model may be physically created using a 3-D printing device.
  • A device may capture an image of the user and generate a 3-D model of the user from the image. A 3-D polygon mesh of an object may be placed in relation to the 3-D model of the user to create a 3-D virtual depiction of the user wearing the object (e.g., a pair of glasses, a hat, a shirt, a belt, etc.). This 3-D scene may then be rendered into a 2-D image to provide the user a virtual depiction of the user in relation to the object. Although some of the examples used herein describe articles of clothing, specifically a virtual try-on pair of glasses, it is understood that the systems and methods described herein may be used to virtually try-on a wide variety of products. Examples of such products may include glasses, clothing, footwear, jewelry, accessories, hair styles, etc.
  • FIG. 1 is a block diagram illustrating one embodiment of an environment 100 in which the present systems and methods may be implemented. In some embodiments, the systems and methods described herein may be performed on a single device (e.g., device 102). For example, a model generator 104 may be located on the device 102. Examples of devices 102 include mobile devices, smart phones, personal computing devices, computers, servers, etc.
  • In some configurations, a device 102 may include a model generator 104, a camera 106, and a display 108. In one example, the device 102 may be coupled to a database 110. In one embodiment, the database 110 may be internal to the device 102. In another embodiment, the database 110 may be external to the device 102. In some configurations, the database 110 may include polygon model data 112 and texture map data 114.
  • In one embodiment, the model generator 104 may enable a user to initiate a process to generate a 3-D model of the user. In some configurations, the model generator 104 may obtain multiple images of the user. For example, the model generator 104 may capture multiple images of a user via the camera 106. For instance, the model generator 104 may capture a video (e.g., a 5 second video) via the camera 106. In some configurations, the model generator 104 may use polygon model data 112 and texture map data 114 to generate a 3-D representation of a user. For example, the polygon model data 112 may include vertex coordinates of a polygon model of the user's head. In some embodiments, the model generator 104 may use color information from the pixels of multiple images of the user to create a texture map of the user. In some configurations, the model generator 104 may generate and/or obtain a 3-D representation of a product. For example, the polygon model data 112 and texture map data 114 may include a 3-D model of a pair of glasses. In some embodiments, the polygon model data 112 may include a polygon model of an object. In some configurations, the texture map data 114 may define a visual aspect (e.g., pixel information) of the 3-D model of the object such as color, texture, shadow, or transparency.
  • In some configurations, the model generator 104 may generate a virtual try-on image by rendering a virtual 3-D space that contains a 3-D model of a user and a 3-D model of a product. In one example, the virtual try-on image may illustrate the user with a rendered version of the product. In some configurations, the model generator 104 may output the virtual try-on image to the display 108 to be displayed to the user.
  • FIG. 2 is a block diagram illustrating another embodiment of an environment 200 in which the present systems and methods may be implemented. In some embodiments, a device 102-a may communicate with a server 206 via a network 204. Example of networks 204 include, local area networks (LAN), wide area networks (WAN), virtual private networks (VPN), wireless networks (using 802.11, for example), cellular networks (using 3G and/or LTE, for example), etc. In some configurations, the network 204 may include the internet. In some configurations, the device 102-a may be one example of the device 102 illustrated in FIG. 1. For example, the device 102-a may include the camera 106, the display 108, and an application 202. It is noted that in some embodiments, the device 102-a may not include a model generator 104. In some embodiments, both a device 102-a and a server 206 may include a model generator 104 where at least a portion of the functions of the model generator 104 are performed separately and/or concurrently on both the device 102-a and the server 206.
  • In some embodiments, the server 206 may include the model generator 104 and may be coupled to the database 110. For example, the model generator 104 may access the polygon model data 112 and the texture map data 114 in the database 110 via the server 206. The database 110 may be internal or external to the server 206.
  • In some configurations, the application 202 may capture multiple images via the camera 106. For example, the application 202 may use the camera 106 to capture a video. Upon capturing the multiple images, the application 202 may process the multiple images to generate result data. In some embodiments, the application 202 may transmit the multiple images to the server 206. Additionally or alternatively, the application 202 may transmit to the server 206 the result data or at least one file associated with the result data.
  • In some configurations, the model generator 104 may process multiple images of a user to generate a 3-D model of the user. The model generator 104 may render a 3-D space that includes the 3-D model of the user and a 3-D polygon model of an object to render a virtual try-on 2-D image of the object and the user. The application 202 may output a display of the user to the display 108 while the camera 106 captures an image of the user.
  • FIG. 3 is a block diagram illustrating one example of a model generator 104-a. The model generator 104-a may be one example of the model generator 104 depicted in FIGS. 1 and/or 2. As depicted, the model generator 104-a may include a scanning module 302, an image processor 304, and a display module 306.
  • In some configurations, the scanning module 302 may obtain a plurality of images of a user. In some embodiments, the scanning module 302 may activate the camera 106 to capture at least one image of the user. Additionally, or alternatively, the scanning module 302 may capture a video of the user.
  • In some embodiments, the image processor 304 may process an image of the user captured by the scanning module 302. The image processor 304 may be configured to generate a 3-D model of the user from the processing of the image. Operations of the image processor 304 are discussed in further detail below.
  • In some configurations, the display module 306 may display a realtime image of the user on a display (e.g. display 108) while obtaining the plurality of images of the user. For example, as the camera 106 captures an image of the user, the captured image of the user may be displayed on the display 108 to provide a visual feedback to the user. In some embodiments, the display module 306 may display a guideline on the display in relation to the displayed real-time image of the user. For example, one or more guidelines may provide a visual cue to the user. For instance, a guideline may provide a visual cue of the direction in which the user should be holding the device 102 (e.g., a tablet computing device in landscape or portrait mode). Additionally, a guideline may provide a visual leveling cue to assist the user in maintaining the device relatively level or in the same plane while the user pans or rotates the device 102 around him- or herself. Additionally, a guideline may provide the user a visual depth cue to assist the user in maintaining the device at a relatively same depth (e.g., at arm's length) while the user pans or rotates the device 102 around the user.
  • FIG. 4 is a block diagram illustrating one example of an image processor 304-a. The image processor 304-a may be one example of the image processor 304 illustrated in FIG. 3. As depicted, the image processor 304 may include a viewpoint module 402, a comparison module 404, a selection module 406, and a cross-correlation module 408. Additionally, the image processor 304-a may include a texture mapping module 410, a geometry module 412, a coefficient module 414, a linear combination module 416, and an application module 418.
  • In some configurations, the viewpoint module 402 may calculate an angle of view relative to the user pictured in at least one of the plurality of images. For example, the viewpoint module 402 may determine that in one image of the user's head, the user held the device 102 10-degrees to the left of center of the user's face. The comparison module 404 may determine whether the calculated angle of view (e.g., 10-degrees to the left of center of the user's face) matches a predetermined viewing angle. In some embodiments, the predetermined viewing angle includes a plurality of evenly spaced 10-degree rotation steps. For example, a head-on image showing the user facing the camera directly may be selected as a viewing angle reference point, or 0-degrees. The next predetermined viewing angles in either direction may include +/−10-degrees, +/−20-degrees, +/−30-degrees, and so forth, in 10-degree increments. Thus, the comparison module 404 may determine that an image depicting the user holding the device 102 10-degrees to the left of center of the user's face matches a predetermined viewing angle of +10-degrees (or −10-degrees).
  • In some embodiments, upon determining the calculated angle of view matches the predetermined viewing angle, the selection module 406 may select at least one of the plurality of images. For example, the selection module 406 may select an image for further processing. The cross-correlation module 408 may perform a cross-correlation algorithm to track a feature between two or more of the plurality of images of the user. For example, the image processor 304-a, via the cross-correlation module 408, may perform template matching. Additionally, or alternatively, the image processor 304-a, via the cross-correlation module 408, may perform a structure from motion algorithm to track features in the images of the user. From the detected features of the user, the image processor 304-a may construct a 3-D model of the user.
  • In some configurations, the texture mapping module 410 may generate texture coordinate information from the determined 3-D structure of the user. The texture coordinate information may relate a two-dimensional (2-D) coordinate (e.g., UV coordinates) of each selected image to a 3-D coordinate (e.g., XYZ coordinates) of the 3-D model of the user.
  • In one embodiment, the geometry module 412 generates at least one geometry file to store data related to a 3-D structure. Each at least one geometry file may include a plurality of vertices corresponding to a universal morphable model. For instance, each geometry file may include a different generic model of a user, where each model depicts a user with certain features and characteristics. For example, one geometry file may include a polygon mesh depicting characteristics typical of a male-looking face. Another geometry file may include a polygon mesh depicting characteristics of a female-looking face, and so forth.
  • In some configurations, the coefficient module 414 calculates a coefficient for each generated geometry file based on the determined 3-D structure of the user. The linear combination module 416 may combine linearly each generated geometry file based on each calculated coefficient to generate a polygon mesh of the user. In other words, each coefficient may act as a weight to determine how much each particular geometry file affects the outcome of linearly combining each geometry file. For example, if the user is a female, then the coefficient module 414 may associate a relatively high coefficient (e.g., 1.0) to a geometry file that depicts female characteristics, and may associate a relatively low coefficient (e.g., 0.01) to a geometry file that depicts male characteristics. Thus, each geometry file may be combined linearly, morphing a 3-D polygon mesh to generate a realistic model of the user based on the 3-D characteristics of the user calculated from one or more captured images of the user. The application module 418 may apply each selected image to the generated polygon mesh of the user according to the generated texture coordinate information, resulting in a 3-D model of the user.
  • FIG. 5 illustrates an example arrangement 500 for capturing an image 504 of a user 502. In particular, the illustrated example arrangement 500 may include the user 502 holding a device 102-b. The device 102-b may include a camera 106-a and a display 108-a. The device 102-b, camera 106-a, and display 108-a may be examples of the device 102, camera 106, and display 108 depicted in FIGS. 1 and/or 2.
  • In one example, the user 502 holds the device 102-b at arm's length with the camera 106-a activated. The camera 106-a may capture an image 504 of the user and the display 108-a may show the captured image 504 to the user 502 (e.g., a real-time feedback image of the user). In some configurations, the camera 106-a may capture a video of the user 502. In some embodiments, the user may pan the device 102-b around the user's face to allow the camera 106-a to capture a video of the user from one side of the user's face to the other side of the user's face. Additionally, or alternatively, the user 502 may capture an image of other areas (e.g., arm, leg, torso, etc.).
  • FIG. 6 is a diagram 600 illustrating an example of a device 102-c for capturing an image 602 of a user. The device 102-c may be one example of the device 102 illustrated in FIGS. 1 and/or 2. As depicted, the device 102-c may include a camera 106-b, a display 108-b, and an application 202-a. The camera 106-b, display 108-b, and application 202-a may each be an example of the respective camera 106, display 108, and application 202 illustrated in FIGS. 1 and/or 2.
  • In one embodiment, the user may operate the device 102-c. For example, the application 202-a may allow the user to interact with and/or operate the device 102-c. In one embodiment, the application 202-a may allow the user to capture an image 605 of the user. For example, the application 202-a may display the captured image 602 on the display 108-b. In some cases, the application 202-a may permit the user to accept or decline the image 602 that was captured.
  • FIG. 7 illustrates an example arrangement 700 of a virtual 3-D space 702. As depicted, the 3-D space 702 of the example arrangement 700 may include a 3-D model of a user's head 704. In some embodiments, the 3-D model of the user's head 704 may include a polygon mesh model of the user's head, which may be stored in the database 110 as polygon data 112. The polygon data 112 of the 3-D model of the user may include 3-D polygon mesh elements such as vertices, edges, faces, polygons, surfaces, and the like. Additionally, or alternatively, the 3-D model of the user's head 704 may include at least one texture map, which may be stored in the database 110 as texture map data 114.
  • FIG. 8 is a flow diagram illustrating one embodiment of a method 800 for generating a 3-D model of a user. In some configurations, the method 800 may be implemented by the model generator 104 illustrated in FIGS. 1, 2, and/or 4. In some configurations, the method 800 may be implemented by the application 202 illustrated in FIG. 2.
  • At block 802, a plurality of images of a user may be obtained. At block 804, an angle of view relative to the user pictured in at least one of the plurality of images may be calculated. At block 806, it may be determined whether the calculated angle of view matches a predetermined viewing angle. In some configurations, the predetermined viewing angle includes a plurality of rotation steps. As explained above, in some configurations, the predetermined viewing angle includes a plurality of evenly spaced 10-degree rotation steps.
