OpenCV3 use is normal, why to 4.1.0 error, the official in the Sample is also no relevant examples, in addition, using class BFMatcher is normal,
The code is as follows:

 Mat img1=imread (" 3. BMP "); 
Mat img2=imread (" 7. BMP "); 
Vector Kpts1 kpts2, kpts3 kpts4; 
Mat desc1 desc2, desc3 desc4; 
//BFMatcher matcher (NORM_HAMMING); 
FlannBasedMatcher matcher. 
Vector
Ptr Detector0=AKAZE: : create (); 
Detector0 - & gt; DetectAndCompute (img1, noArray (), kpts1, desc1); 
Detector0 - & gt; DetectAndCompute (img2, noArray (), kpts2 desc2); 
The matcher. Match (desc1 desc2, matches0);//here collapse 

CodePudding user response:

The new version without the class seems to be due to the patent
