摄像测量学简介与展望

摄像测量学是摄影测量学、计算机视觉、光学测量、数字图像处理分析等学科交叉融合形成的新兴交叉学科,集各学科的优势。在对各种运动、变化过程参数进行测量方面,摄像测量方法具有精度高、自动化、非接触、动态测量、实时测量、易于实施等特点。近十几年来,摄像测量学在国际上发展迅速,国内目前还未见到对摄像测量学的释著述。本文从学科内涵、历史、基本原理、应用、优势和发展前景等方面对摄像测量学进行了简介和展望。

Introduction and Prospect of Videometrics

Videometrics(videogrammetry) is a rising subject combined photogrammetry,computer vision,optical measurement,digital image processing and analysis,etc.The theory and technology of how to estimate an object's 3D structure or movement parameters from its images or videos are to be studied in videometrics.Methods and arithmetic on image processing,camera calibration and 3D estimation are presented constantly.It concentrated the advantages of these subjects.Videometrics has advantages in precise,real time,automatization,untouchment,dynamic and conveniency for movement and distortion measurement.In the last more than ten years,videometrics developed rapidly in the world.But in China,there is still no special and definite article on videometrics.Based on the authors' laboratory's research and practice,this paper gives a general introduction and prospect of videometrics' meanings,history,principles,applications,advantages and futures.Several engineering examples are given.The purpose is to introduce videometrics and promote the research of Chinese videometrics to be more practicable.
