詳解

Features matcher similar to cv::detail::BestOf2NearestMatcher which finds two best matches for each feature and leaves the best one only if the ratio between descriptor distances is greater than the threshold match_conf.

Unlike cv::detail::BestOf2NearestMatcher this matcher uses affine transformation (affine transformation estimate will be placed in matches_info).

inline

Constructs a "best of 2 nearest" matcher that expects affine transformation between images

引数

full_affine	whether to use full affine transformation with 6 degress of freedom or reduced transformation with 4 degrees of freedom using only rotation, translation and uniform scaling
try_use_gpu	Should try to use GPU or not
match_conf	Match distances ration threshold
num_matches_thresh1	Minimum number of matches required for the 2D affine transform estimation used in the inliers classification step
