基于速度估计的双Hough变换运动轨迹检测算法
Velocity estimation-based combinational Hough transform algorithm for moving point target detection
摘要
Abstract
A combinational Hough transform with velocity estimation was proposed to detect the uniform linear moving targe. After pre-estimating the moving point velocity, two combinational Hough transforms (HT) were implemented in different space. In the first HT, the points in the image space were transformed to the p-θ space according to the polar coordinate equation. Then these points were projected to T-L space with they temporal information after a preliminary choosing for trajectories in the space X-Y. In the second HT, points in the T-L space were transformed to the V-S space according to the slope-intercept equation. Finally the projection of these points were limited with their estimated velocity, and the rate of false alarm was further reduced. Experimental results show that the algorithm needs less prior information of the moving point target and can operate in suppressing noise points with less computational cost.关键词
