3D photo creation system and method

#The present application is directed to a photo processing system and method. Specifically, it relates to a 3D photo processing system and method.

#3D photos are commonly created with the application of the lenticular technique. The transparent lens of the lenticular lens is an array of magnifying lenses. Such magnifying lenses array is designed in a way such that when being perceived at slightly different angles, different images are magnified. In order to create a 3D photo, multi-view angle images, such as in 12 or more multi-view angle images, must first be created. Subsequently, the multi-view angle images will be combined into a mixed image. The combination of multi-view angle images is a process of acquiring, from the multi-view angle images, suitable pixels for combining into and forming a new image. The new image comprises the multi-view angle information of the original image. The transparent lens of the lenticular lens is used to reveal the multi-view viewing angles from different viewing angles. Finally, the left and right eyes of the viewer can see different images through observing from the lenticular lens which produces a 3D effect.

#Presently, different methods of creating 3D photos exist. In particular, the most common method is to convert 2D image into multi-view angle images using manual operation. Such method requires a processing time of several hours to several days. Normally, the operator is required to create a mask for extracting a subject from the target image. Then, the operator needs to assign a depth information to the mask based on his own judgment. The depth information is an independent grayscale image possessing the same dimensions as the original 2D image. The grayscale image applies the various shades of gray color to indicate the depth of every part of the image. The manually created depth information leads the computer to shift the pixel of the original 2D image for forming a new view angle map. The depthmap can produce a conspicuous 3D visual effect.

#In order to have a more lucid understanding on the technical feature, purpose and effect of the present application, a detailed description of the embodiments of the present application with reference to the drawings is hereby provided.

#FIGS. 1 to 4 illustrate a diagram of an embodiment of the 3D photo creation system of the present application. Such 3D photo creation system includes a stereo image input module 1, a depth estimation module 2, a multi-view angle image reconstructing module 3 and an image spaced scanning module 4. In particular, the stereo image input module 1 is used to input stereo image. The stereo image includes left eye image and right eye image; the depth estimation module 2 is used to evaluate the depth information of the stereo image and create a depthmap; the multi-view angle image reconstructing module 3 is used to create multi-view angle image according to depthmap and stereo image; the image spaced scanning module 4 is used to adjust the multi-view angle image and form a mixed image.

#In the 3D photo creation system of the present application, the depth estimation module 2 further including: a pixel matching module 21, a depth information confirmation module 22 and a depthmap creation module 23. In particular, the pixel matching module 21 is used to compare the left eye image and right eye image of the stereo image and find the matching pixel between the left eye image and the right eye image, and calculate the optical flow of the pixel according to the optical flow constraint formula. In particular, matching pixel refers to the pixel at the same pixel location of the left eye image and right eye image. The depth information confirmation module 22 is used to find the shifted location of the pixel according to the optical flow of the left eye image and right eye image for confirming the depth information of the pixel. The depthmap creation module 23 is used to create depthmap according to the depth information.
