I just started to study about Multiview stereo vision. But I cannot understand disparity and depth (disparity map and depth map either). Could you give me the intuition? Thanks.

I try to create a Point Cloud based on the images from the KITTI stereo images dataset so then later I could estimate 3D position of some objects. Original images looks like this. What I have so ...

I am trying to construct a stereo vision charuco pose detection. I have been able to stereoCalibrate and I have my intrinsic matrices from both cameras. for sake of development ease I am using the ...

I tried to run code from the OpenCV docs for creating a disparity image from left and right stereo images, but it gives me an error. Here is the code I ran. import cv2 from matplotlib import pyplo...

I'm trying to get a depth map with an uncalibrated method. I can obtain the fundamental matrix by finding correspondent points with SIFT and then using cv2.findFundamentalMat. I then use cv2.stereo...

I want to get real distance of an object from stereo camera. I am using OpenCV example code as given in Learning OpenCV O'Reilly book. After getting disparity map I want to use the formula: dista...

I'm trying to estimate the absolute depth (in meters) from an AVDepthData object based on this equation: depth = baseline x focal_length / (disparity + d_offset). I have all the parameters from cam...

I am working on a stereo camera rig with 4 discrete cameras (of the same type) but at the moment only one pair (cam1 and cam2) are necessary. The aim is to calibrate the stereo pair and get 3D inf...

I currently have a stereo camera setup. I have calibrated both cameras and have the intrinsic matrix for both cameras K1 and K2. K1 = [2297.311, 0, 319.498; 0, 2297.313, 239.499; 0, 0, 1]; K2 ...

I am trying to get the depth map of two stereo images. I have taken the code from this documentation. I get the following error: Traceback (most recent call last): File "depth.py", line 9, in &l...

Could someone here explain what exactly is the baseline of a camera?

I'm working on depth map with OpenCV. I can obtain it but it is reconstructed from the left camera origin and there is a little tilt of this latter and as you can see on the figure, the depth is "s...

I'm trying to get 3D coordinates with a stereo camera. The first method is to calculate directly using this formula. The second method is to use reprojectImageTo3D in opencv. But I do not know ...

I am using OpenCV to capture video streams from two USB webcams (Microsoft LifeCam Studio) in Ubuntu 14.04. I am using very simple VideoCapture code (source here) and am trying to at least view two...

In my mind they both mean reconstructing 3D coordinates from matched points in 2D images. What's the difference between these concepts and multi-view stereo? Which one do you call an algorithm tha...

I get an image point in the left camera (pointL) and the corresponding image point in the right camera (pointR) of my stereo camera using feature matching. The two cameras are parallel and are at t...

I am using a stereo system and so I am trying to get world coordinates of some points by triangulation. My cameras present an angle, the Z axis direction (direction of the depth) is not normal to ...

I have recently started working with OpenCV 3.0 and my goal is to capture a pair of stereo images from a set of stereo cameras, create a proper disparity map, convert the disparity map to a 3D poin...

I recently purchased a Minoru 3d Webcam (http://www.minoru3d.com/) in the hopes of using it to do stereo vision in OpenCV. I thought I had done the proper research before ordering it verifying that...

Although Apple's documentation clearly states they support stereoscopic views on the Mac with the kCGLPFAStereo and NSOpenGLPFAStereo pixel format attributes, I've been unable to get any semblance ...

I am doing a project in opencv to detect obstacle in the path of a blind person using stereo calibration. I have calculated the disparity map correctly. Now to find the distance of obstacle from th...

This is my test code for implementation of a simple testBM algorithm, no prefiltering. But it takes around 400 ms or even more when window size is bigger while the StereoBM of opencv (CPU not GPU) ...

I am working on KITTI data set i am taking 2 images and finding the disparity to get 3D point cloud .The problem which i am facing is that i am not able to get a good disparity map.Most of the disp...

I'm trying to calibrate my two Point Grey (Blackfly) cameras for stereo vision. I'm using the tutorial stereo_calib.cpp that comes with OpenCV (code below). For some reason, I'm getting really bad ...

I am developing an application for treatment of children. It must show different images for left and right eyes. I decided to use cheap red-cyan glasses for separating the fields of view of the eye...
