远距离运动车辆快速跟踪与定位系统设计

为快速跟踪及定位远距离的运动车辆，本文设计了利用单目相机与激光望远测距仪的定位系统。此定位系统装备单目相机、望远测距仪与角度传感器，采用LK光流算法实时跟踪既定目标，构建了相机、测距仪、目标的坐标方程式模型，可实时解算100~300 m外运动目标的位置。该定位系统无需在被测运动车辆上安装任何设施，即可对合作或非合作目标实现跟踪定位。本文以汽车作为运动目标，使用高精度的CORS系统进行精度验证，该系统实时跟踪定位的精度可保持在亚米级。

Design of a fast tracking and positioning system forlong range moving target

In order to track and locate the vehicle target in a long distance,a positioning system based on single camera and laser rangefinder are designed in this paper. The single camera photography,laser rangefinder and angle sensor are equipped for this positioning system. LK optical flow algorithm is used to track the target in real time,the coordinate equation model of camera,rangefinder and target is constructed,so it can track and calculate the position of moving target from 100 meters to 300 meters in real time. The positioning system does not need to install any facilities on the tested moving target,so it can track and locate the cooperative or non-cooperative target. In this paper,a high-precision CORS system is used to verify the accuracy. The accuracy of the system for real-time tracking and positioning of vehicle target is kept at the sub meter level.
