| 摘 要： | 光条投影测量中，在不考虑摄像机镜头畸变的情况下，测量精度不高。提出了一种提高光条投影测量精度的摄像机镜头畸变系数的确定优化方法。从参考平面的测量出发，考察其上的若干测量点，找到其变形与摄像机镜头畸变系数的函数关系，进行最优迭代求解，进而确定摄像机镜头畸变系数。有效地解决了由于镜头畸变给测量带来的误差的问题，提高了测量精度。

| Abstract: | The accuracy of the fringe projection measurement is low in the case of unconsidering the distortion of camera lens. A kind of optimal method of determining the distortion coefficients of camera lens for improving the accuracy of the fringe projection measurement is proposed. Based on measuring the reference plane, the approach analyses the errors of some measure points on it, finds the relationship between the errors and the distortion coefficients of camera lens. Then the distortion coefficients of camera lens are determined by iterative optimization. This method solves the problem of the error caused by the distortion of camera lens effectively and improves the accuracy of measurement. |
