摘　　要：针对视觉成像畸变,提出基于直线透视成像变形的畸变校正方法.无需任何预先参数,利用畸变曲线拟合逼近过中心的近似直线,通过两直线的交点求得图像对称中心.利用径向畸变的数学模型和参数分解的方法对变形量进行线性求解,求得的畸变因子代入成像过程,为最终理想线性透视模型的标定消除畸变对成像的影响.Anamorphic vision images are corrected with perspective model of lines. An approximate line passing through the center is approached by anamorphic curves. Intersection of two different approximate lines is regarded as the image center. Distortion is analyzed with a radial anamorphic model. The anamorphic coefficient is combined with the vision process to correct an anamorphic image for the final calibration of the liner model.
