        所谓关键点,其实就是那些梯度信息特征比较明显的点。至于是多明显,这部分需要用数学公式来进行标识。第一次学的时候,可以先有一个感性的认识。pcl库给出的例子是从RangeImage中提取narf关键点,原代码地址在这,https://pcl.readthedocs.io/projects/tutorials/en/latest/narf_keypoint_extraction.html#narf-keypoint-extraction

1、准备narf.cpp文件

2、准备CMakeLists.txt

3、生成sln工程,准备编译,

4、准备执行narf.exe文件,不用添加参数

        过一会,可以发现有6个关键点,

         也就是上面图形中绿色的部分,当然RangeImage还是少不了的。
