Web6 de ago. de 2024 · 对相似的特征进行区域匹配或者搜索，找到高度相似数据特征片段是特征匹配的主要工作。. OpenCV中支持两种特征匹配方法，分别是暴力匹配与FLANN匹配，对浮点数的特征描述子，FLANN匹配比暴力会明显加快运算，创建FLANN实现匹配，并根据相似度排序，寻找最佳 ... WebHarris是整个角点检测家族的颜值担当。 角点家族的大护法是 J.shi 和 C.Tomasi在1994年提出的 Shi-Tomasi 角点检测算子，它是对 Harris 角点检测算子的改进，并且有一个直接“叫嚣” Harris算子的名字——“Good Feaures to Track”，在opencv中实现函数是 goodfeaturesToTrack。
