摘要

根据反射型立体视觉系统的成像特点

提出了一种基于倒谱分析的反射型立体视觉系统视差估计方法

并利用逆滤波原理对反射型立体视觉系统的重影图像进行复原

获得目标场景的清晰图像。反射型立体视觉系统是一种新型单目测距方式

可以实时获取目标场景的重影图像。首先

将图像分割为矩形观测区域小块;然后

对各观测区域块进行倒谱分析

并通过检测倒谱域峰值位置估计图像的重影位移量(即视差)

计算目标点的三维空间距离;最后

利用估计的视差构造逆滤波器

对重影图像进行逆滤波复原

获取场景清晰图像。通过真实场景实验验证了本文方法的正确性和有效性

结果表明

本文方法的视差估计结果比自相关法提高了15%~20%

实现了稳定视差估计

复原了场景的清晰图像。

Abstract

On the basis of imaging characteristics of a reflection stereo vision

an approach for disparity estimation and image restoration of reflection stereo vision was proposed and the double image of the vision system was restored.The reflection stereo vision is a monocular system

and can capture the double image in real time. In experiment

the image was segmented into the rectangle observing blocks firstly

then

the cepstrum analysis was used to estimate the displacement amount (disparity) of each pixel in the double image by detecting the two symmetrical peaks from the cepstrum domain and to calculate the 3D space distance of a target point. Finally

the disparity was used to combine an inverse filter to restore the double image and to obtain a good scene image. Experimental results show that the method is effective for disparity estimation and image restoration

and the accuracy of the disparity estimation has improved by 15%-20%.
