摘要

PPROBLEM TO BE SOLVED: To provide an image distortion correction method that shortly computes a smoothly varying distortion pattern by interpolating deviations measured by pattern matching at corresponding measurement representative points between a reference image and a compared image. PSOLUTION: The image distortion correction method sets auxiliary representative points other than measurement representative points around an image area to be corrected, corrects a deviation at an auxiliary representative point by extrapolation from deviations measured at nearby measurement representative points, divides all the region of the image area to be corrected into triangles or quadrangles with vertexes on measurement representative points or auxiliary representative points set in the image area to be corrected, and computes a deviation in a triangle or quadrangle by linear interpolation from deviations related to the vertexes of the triangle or quadrangle.

要解决的问题:提供一种图像失真校正方法,该方法通过在参考图像和比较图像之间的对应测量代表点处插入通过图案匹配所测量的偏差,从而短暂地计算出平滑变化的失真图案。

解决方案:图像失真校正方法在要校正的图像区域周围设置除测量代表点以外的辅助代表点,通过对附近测量代表点处测量的偏差进行推断来校正在辅助代表点处的偏差,并对所有区域进行划分在要校正的图像区域中设置的测量代表点或辅助代表点上,将要校正的图像区域的顶点变成三角形或四边形,并通过线性插值从与顶点相关的偏差中计算出三角形或四边形的偏差。三角形或四边形。
