Patent ID: 8659644

Claim:
A method for a stereo video capture system including a stereo video monitor, a control platform, and a three-dimensional (3D) imaging capture device, the method comprising: capturing, by the 3D imaging capture device, at least a first image and a second image, with a parallax between the first image and the second image based on a first parallax configuration; receiving, by the control platform, the first and second images; calculating, by the control platform, a value of at least one parallax setting parameter associated with the first and second images and corresponding to the first parallax configuration, wherein the at least one parallax setting parameter includes a distance between two image-taken positions of the first image and the second image, respectively; determining, by the control platform, whether the value is within a pre-configured range; when the value is out of the pre-configured range, converting, by the control platform, the first parallax configuration into a second parallax configuration; sending, by the control platform, the second parallax configuration to the 3D imaging capture device; adopting, by the 3D imaging capture device, the second parallax configuration in operation; using, by the control platform, the first image as a reference and the second image as a target to perform a first matching from left to right to obtain a left-to-right parallax; using, by the control platform, the second image as a reference and the first image as a target to perform a second matching from right to left to obtain a right-to-left parallax; determining, by the control platform, a disparity between the left-to-right parallax and the right-to-left parallax; removing, by the control platform, mismatched pixels based on the disparity; and provided that a pixel (x L , y) on the left image and a pixel (x R , y) on the right image are a pair of matching points, the left-to-right parallax is denoted as d LR (x L , y), and the right-to-left parallax is denoted as d RL (x R , y), x R =x L +d LR (x L , y), and λ is a predetermined threshold value; determining, by the control platform, that the matching points (x L , y) and (x R , y) are mismatched when |d LR (x L , y)−d RL (x R , y)|≦λ is not satisfied.
