[0068] In order to make the above objectives, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0069] The core concept of the present invention is: when converting from flat video to stereo video, the depth map of the known key frame in the video sequence is used to obtain the depth map of the non-key frame, thereby forming the depth map sequence of the entire video sequence. When acquiring the depth map of the non-key frame, by determining the matching relationship of each feature point on the continuous frame, the movement of the feature point on the continuous frame is obtained, and then according to the depth map of the known key frame, the calculation of each feature point in the non-key The depth value on the frame, and then obtain the depth map of the non-key frame.
