Patent ID: 8406512

Claim:
A stereo matching method based on image intensity quantization comprising the steps of: providing an image pair of an object to a computer performing an image intensity quantization of the image pair by the computer to get a quantization result of the image pair; generating a first extracted image pair by the computer according to the quantization result and the first extracted image pair having a first left image and a first right image; generating a first disparity map by the computer according to the first left image and the first right image; generating a second extracted image pair by the computer according to the quantization result and the second extracted image pair having a second left image and a second right image; generating a second disparity map by the computer according to the second left image and the second right image; and generating a first image error data by the computer according to comparison of the first disparity map with the second disparity map; when an error contained in the first image error data is smaller than or equal to an error threshold value, the second disparity map is output by the computer.
