OpenCV: Real Time pose estimation of a textured object

WebJan 8, 2013 · In your RobusMatch object you can use any of the 2D features detectors of OpenCV. In this case I used cv::ORB features because is based on cv::FAST to detect the keypoints and cv::xfeatures2d::BriefDescriptorExtractor to extract the descriptors which means that is fast and robust to rotations. WebORB is found to be least scale invariant. ORB (1000), BRISK (1000), and AKAZE are more rotation invariant than others. ORB and BRISK are generally more invariant to affine changes as compared to others. SIFT, KAZE, AKAZE, and BRISK have higher accuracy for image rotations as compared to the rest. quiltad kappa
