在尝试跑SLAM14-ch12时遇到两个错误：cv::ORB::create()函数未找到匹配项和Feature2D类中detectAndCompute成员缺失。通过查阅资料和Stack Overflow，发现可能是OpenCV版本问题。将detectAndCompute拆分成单独的detect和compute步骤，成功解决了编译问题。

error1: no matching function for call to ‘cv::ORB::create()’
Ptr< Feature2D > detector = ORB::create();
^

// Ptr< Feature2D > detector = ORB::create();此为原代码
     Ptr<Feature2D> detector = Feature2D::create ( "ORB" );

参考：https://blog.youkuaiyun.com/LittleEmperor/article/details/79698579
备注：Feature2D包含特征检测、描述、匹配等2D特征框架

error2: ‘class cv::Feature2D’ has no member named ‘detectAndCompute’ detector->detectAndComp

 // detector->detectAndCompute( image, Mat(), keypoints, descriptor );此为原代码
        detector->detect( image, keypoints );
        detector->compute( image, keypoints, descriptor );
