这种一般都是OpenCV3->Opencv4迁移的时候，做了很好修改，具体可以参考链接

opencv常见用法和opencv3-＞opencv4版本切换

Ceres报错

一般这个，大家都说是ceres版本的问题，重新切换回更低版本，但是我们总是希望用更高一点的版本去做进一步开发，毕竟新版本可能提高了速度、减少了CPU资源占用、新加了算法、解决了之前的一些bug等等。其实这个问题没那么复杂，只需要把CMakeList中的 set(CMAKE_CXX_FLAGS "-std=c++11")改成set(CMAKE_CXX_FLAGS "-std=c++14")即可

修改后的源码链接

完整可以编译通过的代码，本人已上传，链接如下：
