Questions tagged [stereoscopy]

Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer.

Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer.

This technique is distinguished from 3D displays that display an image in three full dimensions, allowing the observer to increase information about the 3-dimensional objects being displayed by head and eye movements.

How to move epipole to the outside of the image

Hi i had computed the fundamental matrix from two images and i found out that the epipoles lie within the image. I cannot do the rectification using matlab if the image contains epipole. May i know how to compute the fundamental matrix that the…

Stereoscopic rendering

I am trying to come up with an app that renders two videostreams from webcams in a way that they are perceived as stereoscopic image on a 3D display. I have never dealt with stereoscopic 3D before, but thoretically this should be as simple as…

How can I compute the dense disparity map from to stereo images?

How can I compute the dense disparity map from to stereo images ? My idea so far was to go over all the pixels from the first image, and scan the second image for matches. To compare the similarity of two pixels i computed the squared difference of…

Stereoscopy and virtual camera settings

I would like to know if any of you, knows a way to compute two camera matrices (left and right) from a simple camera matrix? In order to have a stereoscopic effect (simulating both eyes of a human being). Thanks for your help.

Is stereoscopy (3D stereo) making a come back?

I'm working on a stereoscopy application in C++ and OpenGL (for medical image visualization). From what I understand, the technology was quite big news about 10 years ago but it seems to have died down since. Now, many companies seem to be investing…

Stereo Calibration and 3D Reconstruction Issue

I am trying to perform stereo camera calibration and 3D reprojection of a calculated disparity image. For the sake of simplicity I made this example in Matlab but getting the same result in Python and OpenCV. I use this piece of code for the…

How to rectify my own image to the cameras of the KITTI dataset using OpenCV

Based on the documentation of stereo-rectify from OpenCV, one can rectify an image based on two camera matrices, their distortion coefficients, and a rotation-translation from one camera to another. I would like to rectify an image I took using my…

Bad disparity map

I am unable to establish a good disparity map, though I have tuned every of parameters of the SGBM algorithm. Changing the length of the baseline does not help either. I do understand, that problems are most likely due to the camera setup. Because,…

8 point algorithm for estimating Fundamental Matrix

I'm watching a lecture about estimating the fundamental matrix for use in stereo vision using the 8 point algorithm. I understand that once we recover the fundamental matrix between two cameras we can compute the epipolar line on one camera given a…
