介绍了一种采用斜光学三角形测量结构和基于虚拟精密测量基准的太阳帆板平面度无接触测量系统及其误差补偿方法.提出的虚拟精密基准的建模与误差补偿技术,解决了在非精密基准上实现精密测量的问题,研制的系统利用现有平台可实现对太阳帆板平面度的高精度测量.测量结果表明,系统对面积为2581mm×1755mm太阳帆板的平面度测量精度达0.02mm(rms).

A solar panel substrate planeness non－contact system, which employs optical triangulation method, and bases on virtual precise measuring datum, is presented. By means of declinate optical triangulation measuring instrument structure which is firstly proposed, the measured area and resolution of this measuring system are greatly increased, and the high accuracy non－contact measurement of the planeness of a large area plane is realized. On the basis of new modeling method of virtual precise measuring datum and measurement error compensation technique, the measuring system can accurately measure the solar panel substrate planeness on a non－precision plate. The actual measurement results show that the measurement accuracy 0.02mm (rms) can be obtained when a solar panel substrate (2581mm×1755mm) planeness is measured by using of this measuring system.
