Stereo Vision .VI Problem

[gbvbalint]

Hello!

I made some pictures with my two cameras, and I would like to get the depth map from them with the LabVIEW's Stereo Vision.vi. But after the calibration has ran, the depth and even the disparity map is full black. Any idea why? There should be a problem with the pictures or with something else? What should I pay attention for?

Thank you!

Hello,

did you try the stero vi's that are posted here?

Does this not work for you?

Best regards,

Hello!

Yes I saw the post, but I couldn"t find the whole code, and one of the links is broken. Can you post your vi-s again?

I am truly sorry, i saw that a part of the code is indeed missing.

I am attaching again.

Best regards,

Hi klemen,

I am trying to use your stereo vision code for my application. I need to compute the disparity image and the depth of the image. I gave the file path for left and right image. I am not sure about waht should be the file path for stereo calibration data. I am not getting any output, Any suggestions how should i go about it.

Thanks in advance

Hello,

firstly, you need to calibrate the stereo system using a grid dot pattern (5-6 images should be enough). Save the calibration file after the successfull calibration. When you know the extrinsic (and intrinsic) parameters of your system, you can obtain depth from disparity.
