lsd.cpp:139: error: (-213:The function/feature is not implemented)

1.问题描述

使用opencv3.4.15，运行线特征SLAM，出现以下报错。

OpenCV(3.4.15) /opt/opencv-3.4.15/modules/imgproc/src/lsd.cpp:139: error: (-213:The function/feature is not implemented) Implementation has been removed due original code license issues in function 'LineSegmentDetectorImpl'

---

2.解决

使用 opencv3.1下的lsd.cpp替换了opencv3.4.15同目录下的lsd.cpp。然后再编译安装。

3.参考

爷青回！我竟然在OpenCV 4.x中使用了LSD算法！

LineSegmentDetector original code liscence issue
