Self-adaptive weighted stereo matching algorithm, stereo display and collecting device and system

The invention discloses a self-adaptive weighted stereo matching algorithm, comprising the steps of: obtaining a binocular stereo image; selecting a pixel supporting window, calculating the real supporting window of each pixel, wherein the supporting windows formed from the supported pixels have different sizes and shapes; calculating the supporting weight in the supporting window; calculating collected energy cost functions; calculating the parallax value of the pixels; and obtaining an original left-to-right parallax map. The invention also discloses a stereo display and collecting device and a system. The self-adaptive weighted stereo matching algorithm, the stereo display and collecting device and the system can be applied to the technical field of stereo display to improve the effect on stereo matching, as well as obtaining necessary three-dimensional information through less data volume.
