摘要
立体视觉技术是随着计算机技术的发展和机器人视觉的研究而迅速发展的一项重要的技术,双目立体视觉技术则是立体视觉技术中的一重要分支,其技术主要包括:视频捕获、摄像机定标、图像预处理和特征提取、立体匹配以及三维重建。
计算机立体视觉研究的主要内容是由多幅二维的平面图像恢复出被拍摄物体的三维坐标,而其中基于两幅图像的双目视觉技术则是一个研究热点。双目立体视觉测量方法具有效率高、精度合适、系统结构简单、成本低等优点,非常适合于制造现场的在线、非接触产品检测和质量控制。双目立体视觉的基本原理与人类视觉的立体感知过程一样,从两个视点观察同一景物,以获取不同视角下的感知图像,通过三角测量原理计算图像像素间的位置偏差,以获取景物的三维信息。
一个完整的双目视觉系统包括多个部分。本论文主要研究摄像机标定和图像特征提取、立体匹配这方面的内容。根据选的立体视觉成像系统模型简单阐述了立体视觉测距的基本原理。并简单阐述了图像处理的一些简单方法。
关键词: 立体视觉立体匹配摄像机定标特征提取
Range Measurement Based On Binocular Stereo Vision
Abstract
Stereo vision technology is an important and rapidly developing technology with the development puter technology and robotic vision research,binocular stereo vision technology is the three-dimensional vision technology in an important branch technology mostly include:video frequency trapping,camera calibration,image preprocessing,feature extraction,stereo matching and Tri-dimensional reconstruction as well.
Computer stereo vision of the main pieces of two-dimensional plane by the images being taken to recover the three-dimensional coordinates of objects, of which two images of stereo vision-based technology is a hotspot. Stereoscopic measurement method has high efficiency, precision fit, simple structure, low cost, very suitable for manufacturing site on-line, non-contact product testing and quality control. The basic principle of binocular stereo vision and the process of human visual perception of three-dimensional, like observing the same scene from two viewpoints in order to obtain the perception of images under different perspectives, through triangulation principles calculate the location of deviation between the image pixels to obtain three-dimensional scene Information..
plete system consists of several parts of binocular vision. In this thesis, camera calibration and image feature extraction, stereo matching content in this area. Based on stereo v
