Flannbasedmatcher searchparams
WebFLANN 匹配器有两个参数，一个是indexParams，另一个是searchParams，以字典的形式进行参数传递。 为了计算匹配，FLANN内部会决定如何处理索引和搜索对象。 索引方法可以选 … WebJan 8, 2011 · Detailed Description Flann-based descriptor matcher. This matcher trains flann::Index_ on a train descriptor collection and calls its nearest search methods to find the best matches. So, this matcher may be faster when matching a large train collection than the brute force matcher.
