Camera Calibration Method in Reverse Engineering

摘要：

Based on the two-dimensional method, camera calibration method was proposed in reverse engineering. First, obtain the initial value through the linear method; second, considering the radical and tangential distortion, optimize the results using maximum likelihood estimation method through the nonlinear method; at last, minimize the error by modifying the actual image point repeatedly. The experimental errors are 0.30267 pixels and 0.24683 pixels, respectively. This demonstrates that the method has a higher accuracy and is an effective and simple calibration method.
