摘要

本文利用ＢＰＳ系统首先产生景物的一对表面方向图，然后：１．分割表面方向图为与景物内物体对应的孤立区域；２．匹配两针国内对应区域间的视差；３．确定物体的３Ｄ表面绝对深度。最后，着重指出怎样识别以下几种主要误差：（１）表面方向测量误差；（２）重建深度误差；（３）极线与扫描线非平行误差等，并且讨论对这些误差进行定量分析与校正的方法。

Abstract

In this paper we produce first a pair of the surface orientation maps of the scene using BPS system.Then:1.segmenting the surface orientation maps into the isolated regions corresponding to the objects in the scene.2. matching the disparities between the corresponding regions.3.determining the absolute depth of 3-D surface of objects.Finally

this paper points out emphatically how to recognize and how to analyse some kinds of the main errors:（1） the measurment error of the surface orientation;（2）the reconstructed depth error

and（3）errors caused by epipolar lines being not always parallel to scan lines

and how to correct them.
