Stereo images rectification and disparity: which algorithms?
I'm trying to figure out what are currently the two most efficent algorithms that permit, starting from a L/R pair of stereo images created using a traditional camera (so affected by some epipolar lines misalignment), to produce a pair of adjusted…

Opencv disparity map from webcams - code does not work
Here is code I have written to get feed from 2 webcams and get a running disparity map. code::blocks returns -1 for this, my webcams lights flash, but nothing happens.
I need it to loop until I press 'q'.
// Live depthmap
#include "cv.h"

missing region in disparity map
i am currently working on stereo processing using opencv2.3 and a Pointgrey Bumblebee2 stereocamera as an input device. Acquiring images is done via the libdc1394.
My code for rectification and stereo processing is the following:

When building an OpenCV project on iOS, why is CvStereoBMState undeclared?
I am working on an iOS project using OpenCV. I am trying to create disparity map of an image. While implementing this, Xcode is showing CvStereoBMState as being an undeclared identifier.
How can I fix this?

Issue with cvReprojectImageTo3D and CV_32FC3
I need your help. I have implemented stereo calibration, rectification using my stereo pair. I have got a disparity image which is quite reasonable. The problem that I face is with cvReprojectImageTo3D.I have used stereobM. And rectified in a…

Stereo depth estimation with two different low quality cameras
I am working on stereo vision depth estimation with two cameras.
The cameras have low quality and the images are pretty blurry and noisy.
Moreover, the sensors are different so the intensity and noise in the images are different.
I did calibration…

What is the best way(algorithim or function) of generating a decent disparity map in c++ or python for implementation on raspberry pi?
I am trying to do some distance calculations using stereo videos in realtime but there is no proper documentation available for disparity mapping for opencv3 and many of the old commands from opencv2 are not working on the latest versions. Is there…

Faster iteration on for loop with 2d arrays
I have a problem with optimization to compute errors for disparity map estimation.
To compute errors I create a class with called methods for each error. I need to iterate for every pixel to get an error.
This arrays are big cause I'm iterating in…
