摘要

根据双目视差原理

可以从一对立体图象中提取物体的三维信息。本文深入研究了立体X线图象的空间特征。通过对成象系统非线性矫正

利用模板相关性去寻找匹配点

实现了一种高精度自动提取立体X线图象空间特征的方法、实验结果

在550.0mm处

深度特征测量相对误差小于0.7％。

Abstract

This paper has made a further research into the space features of stereo X-ray images.A method for extracting space features from stereo X-ray images has been proposed. The method consists of imaging model

correction of the distortion resulted from the system non-linearity and automatic point match of stereo X-ray images. The obtained results have shown that the relative error of measuring depth is less than 0.7% at distance of 550.0mm.
