Embodiment 1

[0047] see figure 1 , the present invention discloses a method for converting a two-dimensional video of a complex scene into a three-dimensional video, the method comprising the steps of:

[0048] [Step 1] Perform scene segmentation on the input two-dimensional video, and divide each frame into a foreground part and a background part.

[0049] The above-mentioned foreground part refers to the main target that is closer to the camera in the video and is the main object of video content, including but not limited to people, animals, vehicles, etc. The background part refers to the main objects in the video that are far away from the camera and are not of interest to the video content, including but not limited to buildings, mountains, and the sky.

[0050]The present invention has no specific limitation on the segmentation method, for example, a segmentation method based on color information or motion information may be used. Of course, other separation methods can also be u...

Abstract

The invention discloses a method and a system for converting a two-dimensional video of a complex scene into a three-dimensional video. The method comprises the steps of: carrying out scene segmentation on an input two-dimensional video, segmenting each frame into a foreground part and a background part; judging the type of a foreground target, carrying out three-dimensional reconstruction on the foreground part according to the type of the target; judging whether the background part moves or not, if so, carrying out three-dimensional reconstruction on the background by using a motion-based reconstructing method, if not, carrying out three-dimensional reconstruction on the background by using a tone-based reconstructing method; synthesizing a three-dimensional reconstruction result obtained from the foreground part into a three-dimensional foreground; synthesizing a three-dimensional reconstruction result obtained from the background part into a three-dimensional background; and synthesizing the synthesized three-dimensional foreground and the synthesized three-dimensional background into the three-dimensional video for outputting. The invention can realize high-accuracy three-dimensional conversion on the two-dimensional video of the complex scene, process different types of targets and different types of videos, and generate the three-dimensional video with vivid effect.

Description

technical field [0001] The invention belongs to the technical field of video conversion, and relates to a video conversion method, in particular to a method for converting a two-dimensional video of a complex scene into a three-dimensional video; meanwhile, the invention also relates to a video conversion system corresponding to the above method. Background technique [0002] Under the background that 3D hardware display devices are becoming more and more mature, the demand for 3D video data is increasing rapidly. Using a 3D camera to shoot new 3D video is a feasible way to provide data, but this way is expensive and cannot take advantage of the existing massive 2D video data. Therefore, there is a huge market demand for the technology of converting the existing 2D video into 3D video. [0003] There are already some published documents on methods and devices for converting two-dimensional data into three-dimensional data. Such as: [0004] Quanta Computer Co., Ltd. of Ta...
