Disparity and depth maps with QT and OpenCV with support for classic image files and MPO stereo pairs

v1.3 - 2019/06/03 - Added openCV Quasi Dense Stereo algorithm + cosmetic changes + openCV 4.1 compatibility

HISTORY

v1.3 - 2019-06-03 - Added openCV Quasi Dense Stereo algorithm + adapted to openCV 4.1
v1.2 - 2018-08-16 - Added visual manual alignment of stereo pair
v1.1 - 2018-07-15 - Added visual measurement of disparity
v1.0 - 2018-07-10 - Implementation of OpenCV stereoBM & stereoSGBM to obtain disparity / depth maps from 3D stereo pairs

LICENSE

The present code is under GPL v3 license, that means you can do almost whatever you want with it! I used bits of code from several sources, mainly from the openCV examples

WHY?

I didn't find any simple tool (understand: GUI) to produce depth maps from my stereo pictures, and also my camera produces MPO files. So why not writing it myself ? I'm not an ace of C++ and QT, in fact I only started using them some month ago. So, if you don't find my code pretty never mind, because it WORKS, and that's all I'm asking of it :)

WITH WHAT?

Developed using:

Linux: Ubuntu 16.04
QT Creator 3.5.1
QT 5.5.1
openCV 4.1 compiled with Contribs (OpenCV's extra modules) - won't work anymore with 3.x due to the Quasi Dense Stereo algorithm

This software should also work under Microsoft Windows: if you tried it successfully please contact me. Maybe someday I'll try to compile a x32 and x64 Windows version

HOW?

You will need the calibration files for your camera / lens, produced by my calibration utility : https://github.com/AbsurdePhoton/calib-mpo If you don't want to use it, you can try "StereoPhoto Maker" (http://stereo.jpn.org/eng/stphmkr/index.html), which has nice auto-alignment functions. It's a Windows utility, but it works fine with Linux with a little help from Wine.

Not much explanations given, the GUI elements have hover tooltips that explain everything.

Just be sure to :

load a stereo pair
align the images
choose your method (BM, SGBM, Quasi Dense)
use the sliders and boxes to change the parameters
for some parameters, you can also use the "Disparity" button
and finally click on "Compute"
of course, you can save the results (config, aligned images, depthmap)

Enjoy!
