Problems solved by technology

[0013] (1) The problem of vertical parallax: For example, if a rocket is launched upwards, no matter how you pick it with the existing method, you can only pick two pictures with vertical parallax, that is, there are only vertical offsets but no horizontal offsets. If such two images are displayed on a stereoscopic display, not only will there be no stereoscopic effect, but it will also make people feel dizzy and fatigued.

Embodiment Construction

[0028] The method for converting a planar video to a stereoscopic video based on an optical flow field proposed by the present invention is described in detail with reference to the embodiments as follows:

[0029] The method of the present invention includes the following steps:

[0030] 1) Calculate the optical flow field of each frame of a given flat video sequence, including:

[0031] 11) Calculation of the optical flow field of the first frame: the first frame and the second frame are calculated to obtain the optical flow field vector of each pixel of the optical flow field of the first frame (The vector of each point of the optical flow field represents the motion displacement vector of the corresponding pixel point from the first frame to the next frame. Its absolute value is in the number of pixels. The specific calculation method of the optical flow field is very mature. No more details);

[0032] Use the first threshold T 1 Filter out the optical flow field vector that ...

Abstract

The invention relates to a method for converting a plane video to a stereoscopic video based on an optical flow field, and belongs to a method for converting a plane video to a stereoscopic video based on an optical flow field; the method includes: calculating the optical flow field of each frame of a given plane video sequence: according to The disparity value is proportional to the absolute value of the optical flow field vector, and the disparity value of the corresponding point is obtained from the unfiltered optical flow field vector in the optical flow field of the current frame; the current frame, the current frame and the disparity map Synthesize to obtain a new view as the left and right views of the current frame; synthesize the left and right views of each frame to obtain a stereoscopic video frame; all stereoscopic video frames form a stereoscopic video sequence. The present invention achieves a good compromise between the complexity of the method and the realization effect, and has the advantage that it is very simple to realize.

Description

Technical field [0001] The invention belongs to the field of computer multimedia technology, and particularly relates to a technology for converting ordinary flat video into stereo video. technical background [0002] The technology of converting flat video to stereo video is getting more and more attention, but due to the difficulty of its realization, there is no more perfect solution so far, which is a subject that is still in the exploratory stage. [0003] Anyone who has watched a 3D movie will be deeply impressed by its sense of reality. That kind of immersive experience is unforgettable. Nowadays, stereoscopic video is gaining more and more in the world and in many industries. Many promotion and favors. For example, the large-scale shopping and entertainment venues in some central cities in China have begun to deploy stereo players. These stereo players are used to play pre-made advertisements or other promotional videos, which gives people a strong visual impact. Power, v...
