| 摘 要： | 根据物方空间的三维直线中心投影到像片平面上也应该是一条直线这一约束条件,首先提取出原始图像中的畸变直线;然后利用畸变模型对其进行畸变纠正,使其满足直线约束条件;最后采用Levenberg-Marquardt算法对非线性方程组进行求解,解出约束优化条件的最佳畸变参数和像主点坐标,并完成对原始影像的纠正。实验结果证明该方法简单快捷,具有较强的实用性。

| Abstract: | According to the line constraint condition,straight lines in 3D world space projecting to straight lines in the image plane,if the lens distortion is compensated correctly,the distorted curved line segments in the original image were detected and linked.Then curved lines were calibrated with distortion model under line constraint condition.Finally,best principle point location and distortion parameters that straightened curved lines were optimized by using non-linear Levenberg-Marquardt algorithm.Thus,disto... |
