摘　　要：以实时跟踪监控多个运动目标为出发点,提出基于激光跟踪小空间搜索的运动轨迹生成方法。激光跟踪测距仪以采集到的激光点和运动目标像素坐标为依据,构建激光自主瞄准模式瞄准运动目标,引导激光靠近运动目标并缩短二者间距离,利用激光跟踪测距仪的小空间搜索性能确定运动目标质心,实现运动目标精准定位检测;采用均值漂移粒子滤波跟踪算法,以检测所得的运动目标位置作为初始粒子跟踪运动目标,获取运动目标跟踪效果图;结合轨迹生成模块,生成运动目标轨迹。实际应用结果表明,检测及跟踪多个运动目标时,准确性高,且生成运动目标轨迹完整且与实际运动轨迹一致,生成结果准确无遗漏可达100%,检测目标车辆的时间均在2.5 s以下,分别低于文献方法2.5 s和1.9 s,降低了检测时间,并且具备性能稳定、实用性强优势。Based on real-time tracking and monitoring of multiple moving targets, a trajectory generation method based on laser tracking small space search is proposed. The laser tracking rangefinder is based on the collected laser points and the pixel coordinates of the moving target, constructs the laser autonomous aiming mode to aim at the moving target, guides the laser near the moving target and shortens the distance between the two, determines the center of mass of the moving target by using the small space search performance of the laser tracking rangefinder, and realizes the accurate positioning detection of the moving target. The mean drift particle filter tracking algorithm is used to detect the moving target position as the initial particle tracking moving target and obtain the moving target tracking effect.Combined with the rail track range Trace generation module to generate moving target trajectory. The practical application results show that the accuracy is high, and the trajectory of the moving target is complete and consistent with the actual trajectory. The generated results are accurate and without omission up to 100%, and the detection time of target vehicles is less than 2. 5 s, which is lower than 2. 5 s and 1. 9 s respectively, and has the advantages of stable performance and strong practicability.
