三维机器视觉中图象匹配的几种摄象机几何模型和误差分析(英文)

SEVERAL CAMERA GEOMETRY MODELS AND ERROR ANALYSIS FOR IMAGE MATCHING IN 3-D MACHINE VISION

三维视觉中的一个主要问题是从不同的角度来确定物体的几何位置，而物体的位置则可由两幅实体图象的视差来确定．本文重点讨论图象匹配中几种摄象机的几何模型和误差分析．

An important task in stereo machine vision is to determine the three-dimensional location ofobjects from different views(images)of the object scene. The actual location of a scene element can bedetermined from the disparity of two (each in deferent image ) of its depicted entities. Prior toestablishing disparity,however,the correspondence problem (or matching problem) must be solved. Inthis paper,we concentrate on the problem of camera geometry modeling. We discuss several kinds ofcamera geometry for image matching in 3D machine vision. And their error analysis is also studied.
