In this post, we learned how to match feature points using three different methods: Brute Force matching with ORB detector, Brute-Force Matching with SIFT detector, and FLANN based matcher. We demonstrate which of these feature matching methods provide the most accurate results. 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： hierarchie information
