传统光流方法对运动目标进行检测时,容易受到噪声、光照因素以及背景扰动的干扰,导致目标检测精度大大降低。面向该种问题,提出一种基于激光跟踪定位的运动目标检测方法,其依据激光点的运动模型,采集激光点以及运动目标的像素坐标,塑造激光自动瞄准模式,通过激光对运动目标进行自主瞄准,完成运动目标的粗定位。采用激光跟踪仪根据激光移动到运动目标时产生的反射光线,迅速锁定运动目标,同时采集目标反射质心,实现运动目标的精准定位。实验表明,所提方法对运动目标进行定位具有较高的定位精度和稳定性。
When the traditional optical flow method is used to detect moving targets, it is easily disturbed by noise, illumination factors and background disturbances, leading to the greatly reduced target detection accuracy. In order to solve this problem, this paper proposes a moving object detection method based on laser tracking and positioning, which collects the laser coordinates and the pixel coordinates of the moving object according to the moving model of the laser spot, shapes the automatic laser aiming mode, , To complete the coarse positioning of the moving target. A laser tracker is used to quickly lock the moving target according to the reflected light when the laser moves to the moving target. At the same time, the target reflecting centroid is collected to achieve the precise positioning of the moving target. Experiments show that the proposed method can locate the moving target with high positioning accuracy and stability.
