Disparity Left & Right

[andrea-unity]

Using your code I'm able to compute the disparity Left, I'm wondering if your algorithm support also Right disparity? Thank you

With some modifications it can support right->left disparity. The correlation sampler returned by corr_block() assumes left->right disparity so the order of the input feature maps will need to be flipped. You should re-train the model since L->R disparity is negative and R->L disparity is positive.

Thank you. I will have a look at the code and I will come back to you.

The reason that I would like the left and the right disparity is because I want to try to use RAFT-3D but it seems I need to pass as input images + disparity (L+R).

Using your code I'm able to compute the disparity Left, I'm wondering if your algorithm support also up or down disparity? Thank you

Hello

I have the same question, could you please give us more hints how to realize the right-left disparity please? This is also linked to the open-issue 69.

Thank you very much in advance. Hai

@HaiLiExp You can also flip both images horizontally and reverse the input order to get the right-left disparity.
