Stereo depth triangulation
網頁This exercise is for learning all about stereoscopic depth maps. The basic idea is that you have multiple views of the same scene, and you know where your cameras are relative to each other - using this information, you can … 網頁2016年3月16日 · One-time effort: It depends on whether you need to do this once, e.g. for one-time calibration, in which case simply make this estimation process real-time, then rotate your stereo camera pair until the depth map variance is minimized. Then lock your camera positions and pray someone doesn't bump into it later.

I'm using a stereo camera, (calibrated with the MATLAB tool), and extracting keypoints from rectified images (I rectify using rectifySteroImages). I implemented a stereo matching algorithm, but now I can not triangulate stereo pairs because I do not know the camera matrices after rectification.
網頁2016年11月18日 · The shorter baseline stereo calculates the distance of the person say 10.2 m and the longer baseline approximates it as 10.6 m. Clearly in this case the measurement from shorter baseline camera is more closer to the actual distance. – Beginner_In_Image_Processing Nov 18, 2016 at 10:27 Now suppose the person moves … 網頁A stereo camera is an arrangement composed of two or more image sensors with fixed positioning between each other.
