| 摘 要： | 通过对CCD相机采集的图像存在的畸变,提出了一种对畸变图像进行校准的方法。校准算法采用标准的棋盘格,利用仿射变换对图像表面规则分布的特征点建立查找表,查找并分析特征点,计算出变形量,然后修正。实验结果表明,该方法对图像校准是非常有效且具有非常高的实用性。

| Abstract: | Images collected by CCD camera,there is usually some distortion.This paper presents a method to calibrate the distortion images.Calibration algorithm uses the standard checkerboard grids.Establish the lookup table use of affine transformation rules for feature points of the regular distribution of the image surface.Find and analyze the feature points,calculate the deformation,and then fix.The measuring results show this method is effective for improving the quality of image correction and very high practica... |
