Undistort Images

[aaronlsmiles]

In the code of the examples 004a UndistortImages.py file, the imgPath points to a couple of calibration images.

In practice we would not do this though, correct? In practice we would use this code to undistort images of scenes, not the calibration images, or am I misunderstanding the pipeline?

Nope, the imgPath defined here is just the directory.

Yes, you can undistort any image taken from the camera after calibration. Then you can undistort any scenes, including the calibration ones!

Normal pipeline is:

1. calibrate
2. rectify
3. take left and right scene pictures
4. stereo matching
5. triangulation and 3D reconstruction

[aaronlsmiles]

Where does Undistort fit in that pipeline though? I'm assuming it must be done before step 4 (stereo matching)?

[decadenza]

Is optional after 3... You may need undistorted images.
Otherwise distortion is automatically corrected during triangulation.
