transform depth to real distance?

Hi, could you tell me how to get real distance from depth map?
I'm not the person who made this code, but you would have to find the part which the program makes the prediction, and the prediction is likely to be a matrix. Then, the program would convert the predictions into an image with colors corresponding to the distance. However, before that, you would have to save the array.
According my understand，this code does not generate depth map but only generates disparity map.

Could you please explain the difference between depth and disparity map?

Hi, disparity can be easily understood based on the binocular camera model.But I can't understand disparity map. In the author's paper, it seems that the disparity map is directly compared with the ground truth.Do you mind adding my Facebook for the convenience of communication?
With a known focal length and camera baseline you can convert disparity to depth. Both of these quantities are available in the KITTI stereo dataset.

Hi, How can I get the focal and the baseline of the KITTI datasets? Many thanks in advance for your reply.
