Embodiment 1
[0073] Such as figure 2 As shown, the embodiment of the present invention provides a parallax adjustment method, which is applied to the pre-parallax adjustment link in the S3D animation production process, and the method includes:
[0074] S201. Obtain an image to be adjusted;
[0075] In practical applications, a scene of S3D animation usually consists of many single-frame images. Animators first determine the target 3D animation scene to be adjusted according to the needs of the animation plot, and then form the target 3D animation scene from the already produced ones. The image to be adjusted is determined from the multiple frames of images.
[0076] S202. Determine a stereo parameter value of a virtual stereo camera group, wherein the virtual stereo camera group includes at least a central virtual stereo camera;
[0077] figure 1 It shows a schematic diagram of the shooting model of the virtual stereo camera group used in the embodiment of the present invention, refer...
Embodiment 2
[0110] Optionally, adjusting the disparity of the image to be adjusted according to the disparity gradient map in step S206 in Embodiment 1 includes:
[0111] Step 1, obtain the parallax threshold;
[0112] The parallax threshold mentioned above may be a threshold determined according to the experience of an animator, or may be a threshold determined by other methods.
[0113] Step 2. Determine the pixels whose disparity exceeds the disparity threshold in the disparity gradient map, and re-identify the determined pixels in a first preset manner;
[0114] Wherein, the first preset method is a method different from the existing pixel identification method, for example, the first preset method may be the fourth preset color identification method, or the first preset method may be grid-covered way and so on.
[0115] Step 3. Adjust the disparity corresponding to each pixel in the image to be adjusted according to the re-identified disparity gradient map.
[0116] The specific a...
Embodiment 3
[0119] Because the animation production equipment and the actual projection equipment are usually different, for example, people usually use PC or workstation display equipment to produce animation, while the actual animation display equipment can be a TV screen, a large screen in a movie theater or a mobile phone screen etc. It is understandable that the three-dimensional effect observed on the production equipment and the three-dimensional effect displayed on the actual projection equipment are very likely to be different. However, the current animators have not considered the actual projection equipment and production Due to the difference in equipment, the three-dimensional effect of the finished animation is not ideal when it is actually shown.
[0120] In order to solve the above problems, Embodiment 3 of the present invention specifically adopts the following method to obtain the parallax threshold described in Step 1 in Embodiment 2:
[0121] First, determine the stere...
