## Geometric Measurement Based on Single Image:A Survey

• 摘要: 为进一步促进单幅图像几何量测理论和技术的研究深化,拓展其应用领域,对近十年来单幅图像几何量测技术和方法进行了分析和总结。首先总结提炼了单幅图像几何量测的基本原理,即直接几何量测和间接几何量测,论述了各自的数学背景;在此原理下,将单幅图像几何量测方法分为基于单应的量测方法和基于几何关系的量测方法,并对各类算法的原理、约束条件、求解方法进行了详细讨论,阐明了算法的优缺点。

Abstract: Since sometimes it is hard to obtain two or more images of one scene,especially history images,even so it still uneasy to self-calibrate because of the diversity,universality and randomicity of images and the variable camera parameters when taking different scenes.Single image measurement which benefits from avoiding the process of match and self-calibration of two or more images has been,in the past few years,amongst the main aims of Photogrammetry,Computer Vision,Videometrics and other fields.This paper addresses the problem of extracting geometric information from a single,uncalibrated image of a scene.Firstly,basic principles ofgeometric measurement based on single images are summarized.Secondly,approaches for single image measurement are surveyed according to their principles.Finally,several prospective focuses of this field of research are suggested.
