A new survey adjustment method for laser tracker relocation

Abstract

The relocation function is frequently used in the application of Laser Tracker. However, in large component assembly, since the laser tracker would be blocked by the large-size component, the number and distribution of fiducial points can hardly meet the requirement of laser tracker relocation, resulting in a low relocation accuracy. To solve this problem, we present a new laser tracker relocation method based on survey adjustment, which reduces the fiducial point location error by survey adjustment, thereby improving the laser tracker relocation accuracy. Simulations show that the proposed method improves the laser tracker relocation accuracy clearly especially in large component assembly.
