激光自动跟踪空间坐标测量系统的发展(一)

Development of Laser Automatic Tracing Space Coordinate Measurement System (1)

介绍了近十年来国外在激光跟踪空间坐标动态测量方面的研究成果。它集多种现代先进技术于一体，目前多应用于机器人领域，但应用的前景非常广阔，代表了计量学新的发展方向。下面将介绍球坐标法、三角法、多边法等多种测量方法，讨论单站、多站（双站、三站和四站）的测量原理及系统结构，还分析了各系统可能或已经达到到的精度及优缺点。

The research work conducted abroad in dynamic coordinate measurement with lasertracing technique during the past ten years are described in this paper. Several kinds of advancedtechnique are integrated in measuring system. Though its usages have almost been limited in thecalibration of robots, it has opened up the bright prospect for more wide industrial applications. It canbe asserted that this represents the new developing trends of metrology. Several measurementmethods, including the spherical approach, the triangulation method and the multi-lateration methodare described. We also illustrate the principles and structures of the signal - station system and themulti - station system (including tow -station, three - station and four - station system ). Finally,precision and accuracy the systems have already got or possibly get, and advantages as well asdisadvantages are analyzed.
