scanRegistration.cpp文件中的465行 double cc = fabs( norm_front.dot(norm_back) / (norm_front.norm()*norm_back.norm()) ); if(cc < 0.8){ debugnum3++; }else{ CloudFeatureFlag[i] = 0; } 这个if的作用是什么,为什么abs(cos(t))<0.8(t属于[37度,143度])就不是角特征点了?

Hi guojing-gj
这个 if 限制的是只取 (cc < 0.8) 内的点 即 属于[37度,143度] 内的点; 具体的参数并不是定死的 这个阈值是可以调的; 角特征点更倾向于90度左右的点;这个范围只是个例子
Sorry, something went wrong.
