摘　　要：针对常规飞机水平测量方法存在的低精度、低效率及数据处理工作量大等实际问题,本文提出了一种基于激光雷达光学测量系统的水平测量方法。首先对激光雷达测量系统进行了原理分析,并基于此原理进行了相应的飞机水平测量方案设计,同时进一步深入研究了数字化水平测量的关键技术,包括CCD图像处理技术及转站测量技术。通过实际测试,各特征点的合成总误差均小于给定的综合误差0.5 mm,满足方案设计的测量精度指标要求。In view of the actual problems existed in the horizontal measure technology,such as lower accuracy,lower efficiency and heavy workload of data processing.A new horizontal measuring scheme based on the optical measure-ment system of laser radar is put forward.Initially,the principle of the laser radar measurement system was analyzed. Horizontal measurement of corresponding aircraft was designed on the basis of the principle.And then,the key tech-nologies of digitization horizontal measurement were further studied,including CCD image process and transmission station measurement.After the actual detection,the combined error of each feature point is smaller than the compre-hensive error of 0.5mm,which meets the accuracy of measuring scheme.
