WebJan 8, 2013 · virtual void cv::FlannBasedMatcher::train. (. ) virtual. Trains a descriptor matcher. Trains a descriptor matcher (for example, the flann index). In all methods to match, the method train () is run every time before matching. Some descriptor matchers (for example, BruteForceMatcher) have an empty implementation of this method. WebMar 12, 2015 · DescriptorMatcher是匹配特征向量的抽象类,在OpenCV2中的特征匹配方法都继承自该类(例如:BFmatcher,FlannBasedMatcher)。. 该类主要包含了两组匹配方法:图像对之间的匹配以及图像和一个图像集之间的匹配。. 用于图像对之间匹配的方法的声明. // Find one best match for ...
