下述问题均为执行./build.sh时出现的报错。

1. LocalMapping.cc:628:49: error: no match for ‘operator/’

ORB_SLAM3/src/LocalMapping.cc:628:49: error: no match for ‘operator/’ (operand types are ‘cv::Matx<float, 3, 1>’ and ‘float’) x3D = x3D_h.get_minor<3,1>(0,0) / x3D_h(3);

似曾相识的报错，参考以前的博客，指路https://blog.youkuaiyun.com/warningm_dm/article/details/118361259。

2. ORB_SLAM3/src/CameraModels/KannalaBrandt8.cpp:534:41: error: no match for ‘operator/’ (operand types are ‘cv::Matx<float, 3, 1>’ and ‘float’)

同上。
