激光跟踪仪的双面互瞄定向
Two-face reciprocal orientation for laser tracker
摘要
Abstract
As traditional orientation method depends heavily on measurement spaces and it is great dif-ficult to implement the orientation of large dimension instruments in a limited space .Therefore ,a two-face reciprocal orientation method was proposed to implement the orientation of a spherical coor-dinate measurement system in the limited space ,and the theory analysis and experiment verification were performed by taking two laser trackers for example .With combination of measuring principle and working characteristics of laser trackers ,the geometrical constraints of the method were construc-ted by motion characteristics of the probes in trackers .So ,if the instruments to be measured were visi-ble each other ,they will be orientated by the smaller public view field .The mathematical modeling and optimization of this method were elaborated .Then ,the experimental verification was performed on an establishment processing of circular measuring control network in Shanghai Synchrotron Radia-tion Facility(SSRF) .The results indicate that the precision of the proposed method is within 0 .12 mm and the orientation rotation angle error is less than 1 .5″when the two laser trackers are 5m away from each other .As compared to that of traditional orientation method ,the measuring efficiency of the method has been obviously promoted with almost the same precision level in a limited space .The method can also be applied to other single station coordinate measuring systems .关键词
