(OpenCV Stitching) matchesGraphAsString function

"matchesGraphAsString " is useful function to see the stitching relationship graph.

The function gives the result as to string.

 

 

As figure, we can know m6-m7-m8-m9 is linked and S1, S6 is not correlation with the group.

You have to get pairwise_matches before using the function.
The matching method is introduced on

After get pairwise_matches, you can get the result of stitching grouping as this example source code.

...

float conf_thresh=1.0;
 vector< cv::String > img_names;
 img_names.push_back( "m7.jpg");   
 img_names.push_back( "S1.jpg");   
 img_names.push_back( "m9.jpg");   
 img_names.push_back( "m6.jpg");   
 img_names.push_back( "S6.jpg");   
 img_names.push_back( "m8.jpg"); 
 ofstream f("graph.txt");
 f << detail::matchesGraphAsString(img_names, pairwise_matches, conf_thresh);
