Abstract

The invention discloses a stereoscopic video optimal fusion parallax imaging method and device, the device comprises a dual-optical-path imaging unit, a parallax mechanical adjusting unit and a digital control unit, the optimal fusion parallax range of a display is determined according to display parameters, and the vertical parallax of a stereoscopic image is obtained by calculating matching feature points of a left image and a right image. According to the vertical parallax and the pixel size of a stereoscopic video, the mechanical structure adjusting amount in the vertical direction is calculated, the minimum horizontal parallax and the maximum horizontal parallax are obtained by calculating matching feature points of a left image and a right image, and whether the range of the maximum horizontal parallax and the range of the minimum horizontal parallax meet the optimal image fusion parallax range or not is judged. And calculating the mechanical structure adjusting quantity in the parallel image plane direction. The three-dimensional display device can be suitable for different display devices, and the optimal three-dimensional display effect can be achieved on the different display devices.

Description

technical field [0001] The present invention relates to the technical field of stereoscopic video, in particular to a stereoscopic video acquisition device and an optimal fusion parallax imaging method. Background technique [0002] Stereoscopic video technology is the future development direction of multimedia technology, it is a new type of video technology that can provide stereoscopic effect. Compared with planar video, stereoscopic video requires at least two video imaging channels. The principle of stereoscopic video imaging simulates the principle of stereoscopic imaging of the human eye. The left and right images are used to simulate human binocular imaging. The difference between the viewing directions of the left and right images produces image parallax, and the image parallax forms a three-dimensional sense in the brain. For the display of stereoscopic video, factors such as viewing distance, stereoscopic display size, picture resolution, and pixel size will all ...
