Method for Coordinate Acquisition of Camera and Measured Surface in Deflectometry
摘要
提出了一种偏折术中相机和被测面坐标的获取方法。通过斜率计算和面形重建,对一块圆形的窗玻璃进行了检测,最终检测结果与基于干涉仪及张正友标定法检测得到的结果近似,证明了该方法的可行性和正确性。研究结果表明,所提方法的标定过程简单、灵活,能够完成相机和被测面的全局标定,适用于在线测量的标定。
Abstract
A method to acquire the coordinates of camera and measured surfaces in the deflectometry is proposed. A circular window glass is tested by the slope calculation and the shape reconstruction. The final test results by the proposed method are close to those by the interferometer and the Zhang's calibration method, and the feasibility and correctness of the proposed method are proved. The research results show that the calibration by the proposed method is simple and flexible. This method can be used to achieve the global calibration of cameras and the measured surfaces, and is suitable for the calibration of online measurements.
