【摘要】 针对结构光视觉传感器所组成的多视觉测量系统，本文提出一种直接线性转换全局定标法，把各传感器的模块坐标归结到一个统一的用户坐标中。该系统用于轿车白车身有关参数的快速检测。标定后的系统对轿车进行检测，经与三坐标测量机测量结果比较，３σ＝０．５ｍｍ，完全满足车身公差±２ｍｍ的要求。更多还原

【Abstract】 Anning at the actual requirement of a body-in-white visual inspection system, and according to features of two structured light sensors, this paper proposes a global calibration method by using tile direct linear transformation based on describing the multi-visual inspection system calibration in detail. The authors also design a corresponding calibrating device, and solve the sighting problem between target and structured light. Experiment results show that the global calibration method is feasible and practical.更多还原
