WebFeb 15, 2024 · FlannBasedMatcher is also used to match or search for the features of one image to another image. this function is available in the OpenCV library. It uses Nearest Neighbors Approach and usually runs faster than BruteForceMatcher for various datasets. It also works great with large datasets. Web当然也可以通过调整FlannBasedMatcher的参数来提高匹配的精度或者提高算法速度,但是相应地算法速度或者算法精度会受到影响[8]。 特征匹配也有两种方式,可以直接进行暴力检测,也可以采用KNN进行检测,不同检测方式的代码如下:

Brute-Force matcher is simple. It takes the descriptor of one feature in first set and is matched with all other features in second set using some distance calculation. And the closest one is returned. For BF matcher, first we have to create the BFMatcher object using cv2.BFMatcher (). It takes two optional params.
