摘要
基于相位测量偏折术,构建了一个由LED平板显示器、被测镜面物体和CCD摄像机组成的测量系统。提出一种一般几何设置下测量几何模型及其系统的标定方法。该方法对设备要求低,灵活度、精度较高。对凹面镜的初步实验结果证明了该方法的可行性。
The phase measuring deflection is used as a basic technical principle,a measurement system composed of an LED plate display,a measured mirror object and a CCD camera is constructed.The geometric and physical model for general geometric settings and the corresponding calibration method is proposed,which has low equipment,high flexibility and accuracy.The preliminary experimental results of concave mirror demonstrate the feasibility of this method.
