Velocity restraint-based Hough transformation fast track starting method

基于速度约束的Hough变换快速航迹起始方法

Abstract

The invention provides a velocity restraint-based new Hough transformation fast track starting method under dense cluttered environment. The method comprises the following steps: performing combination pairing and velocity restraint on data measured by a sensor in all scanning periods, deleting a part of pairs formed by clutter, resolving the accurate intersection points of pairs in a parameter space by utilizing a Hough transformation formula, extracting public intersection points through the segmentation and threshold setting of the parameter space, to obtain a candidate track, and screening the following track by utilizing the speed restraint, to obtain a final confirmation track. According to the method, the false track formed by the clutter can be effectively inhibited, the fast starting of the track can be guaranteed, and better robustness on the clutter interference can be achieved.
本发明提供了一种密集杂波环境下基于速度约束的Hough变换的航迹快速起始新方法。该方法通过对各扫描周期内的传感器量测数据进行组合配对和速度约束,删除部分由杂波形成的配对,利用Hough变换公式求出各配对在参数空间中准确的交点,通过参数空间分割和门限设置提取出公共交点,得到候选航迹,再次利用速度约束对后续航迹进行筛选,得到最终的确认航迹。该方法有效地抑制了杂波形成的虚假航迹,保证了航迹的快速起始,对杂波干扰具有更好地稳健性。
