A Tracking Method for a Moving Object Based on POC Method
Hitoshi NAMBA,Mitsuji MUNEYASU 대한전자공학회 2007 ITC-CSCC :International Technical Conference on Ci Vol.2007 No.7
This paper proposes a new tracking method for a moving object based on phase only correlation (POC). The POC method can measure exactly displacement between the corresponding points of two images. The proposed method applies the POC method to detecting and tracking the moving object. In the tracking of the moving object by an in-vehicle camera, it is difficult to use the techniques based on background difference or frame difference. The improvement of the detection accuracy is not also easy. To solve this problem, an initial point search method by the POC based calculation technique of motion vectors and a tracking method by using the coarse-to-fine search technique based on the POC method are proposed. By applying the proposed method to moving pictures taken by the in-vehicle camera, the good result for the tracking of the oncoming car in it is shown.
