Rectification! Active stereo vision systems! Stereo. Correspondence problem! focuses specifically on stereo vis ion sensing. 2 stereo vision sy stems is 3D from Stereo Images: Triangulation For stereo cameras with parallel optical axes, focal length f, baseline b, corresponding image points (xl,yl) and (xr,yr), the location of the 3D point can be derived from previous slide’s equations: Depth z = fb (xlxr) = fb/d x = xlz/f or b + xrz/f y = ylz/f or yrz/f This method of determining Stereo Vision What is the goal stereo vision?-The recovery of the 3D structure of a scene using twoormore images of the 3D scene, each acquired from a different viewpoint in space.-The images can be obtained using muliple cameras or one moving camera.-The term binocular vision is used when twocameras are employed 9 & VisionStanford University Fei-Fei Li Lecture&Algorithm: Re-project image planes onto a common plane parallel to the line between optical centers Pixel motion is horizontal after Plan Stereo vision! We implement such a 4,  · achieve the task of 3D imaging from the real w orld. Fei-Fei Li Lecture&Algorithm: Re-project image planes onto a common plane parallel to the line between optical centers Pixel motion is horizontal after Stereo vision is a well-known technology for inferring depth and, excluding projection-based approaches, it is a passive technology based on standard imaging sensors Stereo Vision – A simple system. Stereo. Ability to infer information on theD structure and distance of a scene from two or more images taken case for a hybrid stereo vision system where the best stereo vision algorithm for a stereo image pair is chosen by a pre-dictor dynamically, in real-time.
