A kind of adaptive ORB method for tracking target

The present invention provides a kind of adaptive ORB method for tracking target, do not have the problem of direction to FAST feature, it joined the directional information of FAST feature, in feature point description part then using the BRIEF Feature Descriptor compared based on pixel binary digit, and it improves BRIEF and describes sub sensitive to picture noise and do not have the shortcomings that rotational invariance, compared with SIFT algorithm, ORB algorithm not only has rotational invariance and noise resisting ability, while arithmetic speed ratio SIFT algorithm improves two orders of magnitude.Adaptive ORB method for tracking target of the invention takes full advantage of this characteristic of ORB algorithm, and further improvement is made to ORB algorithm, then adaptive ORB algorithm is proposed on this basis, further increases the speed of operation and the accuracy of tracking, is more in line with the requirement of real-time tracking.
