Optimization Method on Structure Parameters of Intersected Measuring System with Dual-CCD

This passage creates a math model of intersected measuring system with dual-CCD based on analyzing the possible error of untouched-mode coordinate measuring technology, and does error analysis of math model, and then presents four conditions of optimizing structure parameters. And then, it makes optimization design for structure parameters of intersected measuring system with dual-CCD by computer simulation, so as different optimization results according to different size of target are obtained. At last, it proves that optical axis must intersect orthogonal when dual-CCD measuring is used, which can be used in later measures.
