The matching accuracy of remote sensing image-pair has a great relationship with the brightness value of the corresponding points. Generally the corresponding points of remote image-pair have great brightness difference, which may affect and reduce the matching precision. Therefore, in order to acquire high-precision stereo matching, a new method was proposed in this paper. This method can balance the brightness by combining the local information and middle axis cumulative histogram of image-pair and can adjust the brightness difference to be the same between image-pair. Both theoretical analysis and experimental results show that this new method can achieve better result in balancing brightness difference, keeping details and improving matching accuracy of remote sensing stereo image-pair effectively.
