基于大景深三维扫描系统对RAC标定法的修正

Modification of RAC Camera Calibration Method Based on Large Depth-of-view 3D Laser Scanner

基于大景深三维扫描系统的倾斜摄像机模型,推导了新的物像关系并修正了Tsai的RAC标定法.利用修正后的RAC标定法对大景深扫描系统的摄像机进行了标定,实验结果表明修正后的RAC标定法适用于倾斜的摄像机系统,标定准确度可以达到0.03mm.

Base on the tilted camera model, new obiect-image equations are derived theoretically and the RAC method of Tsai is modified. Using the modified RAC method, the camera of large depth-of-view 3D laser scanning system is calibrated successfully. The experimental results show that the modified RAC method can solve the titled camera model. The standard deviation of calibration is lower than 0.03 ram.
