摘要
运动目标空间位置激光跟踪测量是计量测试领域的前沿课题，该测量系统集激光干涉测距、光电检测、精密机械、计算机及控制系统和现代数值计算于一体，对空间运动目标进行跟踪并实时测量其坐标和姿态。测量范围１－１０ｍ，测量精度５０μｍ／ｍ。采用多个激光干涉仪进行冗余设计，对测点造成过定位，通过解最小二乘方程组计算出被测点的坐标。文中论述了多站法跟踪测量的原理并建立了计算坐标的数学理论模型。
The laser tracking measurement of spacial moving targets, which combines the techniques of laser interferometry, photoelectric detection, precision mechanism, computer, control system and modern numerical computation, is one of the frontiers in metrology. The moving targets are tracked, and their spacial positions and attitudes are measured in real time. The measuring range is up to 10m, with accuracy of 50μm/m. If more than one laser interferometers are used to give a redundant design, the tested points will be overdetermined. The positions of the targets can be obtained by using the least square method. This article discusses the principles of multistation laser tracking and measuring system, and gives a mathematical model to calculate the coordinates of moving targets.
