BUG(跑SLAM14-ch12)

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 detector = Feature2D::create ( "ORB" );

参考：https://blog.csdn.net/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 );

感觉像是版本问题，没有找到这个函数，故把这个函数拆开来运行，成功！
