一种案件现场全景图像的精确匹配算法

图像匹配是全景图像拼接过程中的核心技术。本文针对犯罪案件现场重建过程中的图像匹配环节,提出了一种精确的匹配算法。算法首先用分割线对待匹配图像交叉分块;再采用小波多尺度变换边缘检测算法对分出的每一子模块提取边缘;运用自适应直线拟合方法在提取出的边缘中查找出角点,作为匹配的准特征点;平移分割线后再重复一遍上述准特征点提取过程,并对两次提取出的准特征点作交集运算;将运算得到的点作为最终的特征点进行图像匹配。实验证明,该算法能够精确地实现现场图像的匹配。

A Precise Matching Algorithm for the Panaramic Image of Criminal Scenes

Image matching is the kernel technique of the process of panoramic image mosaics.In allusion to the image matching segment in the scene reestablishment of the crimes,this paper puts forward a precise matching algorithm.Firstly,the images to be matched are crossed and blocked by the cut-off lines.A wavelet transform edge detection algorithm is used to extract the edges of each sub-block.Then a self-adapt$ation linear fitting method is applied to finding the corner points in the extracted edges,and these poin...
