Abstract
To control the manufacturing and assembly precision of the large scale equipments, a combinatorial measurement system composed of a laser tracker and a multi-joints measuring arm was constructed. A spatial registration method for redundant data based on least residual sum of squares was proposed, and a weighted fusion criterion based on least measuring uncertainty was obtained. The experimental results showed that the combinatorial measurement method overcame the defects which the measurement error accumulated with the increase of the number of moving stations in the traditional leapfrog measurement, and fully embodied the technical advantages of extra precision, high speed and high efficiency.
