Abstract

The invention discloses a 3D video / image generation method for an internet application. The method comprises the following steps: converting the color of a 2D video / image, calculating Y components of a YUV or YCRCB image, and carrying out superpixel division on Y component images; calculating a mean Y' of the Y components in each superpixel area, and merging adjacent superpixels according to the difference of the Y' values; counting the number N of the merged superpixels, averaging [0, 255] into N equal parts to obtain N valuing intervals; sequencing the means of the Y components in the merged superpixel areas according to the size to obtain a sequence number N', finding a corresponding interval according to the size of the sequence number, and using a numerical value in the intervalas a depth value to obtain a depth map; and drawing another viewpoint video or image, and jointly outputting the 3D video / image together with an originally input video. According to the 3D video / image generation method disclosed by the invention, the three-dimensional spatial relation of objects in the scene is analyzed to recover the depth information of the scene, and the 3D video / image is generated accordingly, so as to accelerate the speed and save the manufacturing cost and time.

Description

technical field [0001] The invention relates to the technical field of electronic imaging, in particular to a method for generating 3D video / image for Internet applications. Background technique [0002] At present, the imaging of 3D video or image mainly depends on the synchronous shooting of binocular cameras, which generally has a relatively high production cost, and requires a relatively professional alignment and calibration process in the later use process, which brings inconvenience to ordinary users and also Therefore, the application of 3D video or image imaging products is limited. [0003] The existing 2D to 3D methods are divided into two categories, one is to generate the two viewpoint images required by 3D directly through the geometric deformation of the image without analyzing the scene content. Such methods are fast, but their 3D quality is poor. The second type of method is to do scene analysis, convert the scene depth information, and then generate the r...
