快速随机Hough变换航迹起始算法

A Track Initiation Method Based on Fast Randomized Hough Transform

针对基于Hough变换航迹起始算法存在的虚警率过高现象,提出了一种快速随机Hough变换(FRHT)航迹起始算法。该算法充分考虑了目标的运动信息,使用了序列采样策略,并利用采样终止规则限制采样次数,从而保证了该算法具有较高的航迹起始成功率,并且大大缩短了航迹起始时间。仿真结果表明了算法的有效性。

The track initiation method based on Hough transform usually has high false alarm rate,thus we put forward a track initiation method based on Fast Randomized Hough Transform（FRHT）.The movement information of the target was taken into consideration and sequential sampling was used in the proposed method.The times for sampling was reduced by using terminative rule for sampling,and thus the algorithm may have high track initiation rate and short initiation time.Simulation result of multi-target track initiation shows that the FRHT track initiation method works well.
