WebJun 19, 2024 · 作者David LEEOpencv里的SGBM算法，之所以叫SGBM是因为opencv并没有使用MI作为匹配代价，而是仍然使用了块匹配的方法，相关cost的度量为Birchfield-Tomasi metric。而且opencv提供了多种cost aggregation的方式，包括只使用3个、5个或全部8个方向的方法。总体上的实现也比较直观，结合论文也比较好懂。 WebStan Birchfield and Carlo Tomasi Abstract—Because of image sampling, traditional measures of pixel dissimilarity can assign a large value to two corresponding pixels in a stereo pair, even in the absence of noise and other degrading effects. We propose a measure of dissimilarity that is provably insensitive to
