Request for data preprocessing code about bpnpnet

Hi Sergio,

I'll contact my co-author who looked after the pre-processing and get back to you shortly.

Cheers,
Dylan

Hi @SergioRAgostinho, I don't have the pre-processing code yet, but I can outline it for you:

1. read out the SfM model from the dataset
2. go through each image in the model
3. read its keypoints, rotation matrix, translation vector, intrinsic matrix, distortion parameters
4. undistort the coordinates of keypoints
5. for each keypoint, fetch its visible 3D index and save the 3D coordinates

Hope this helps!

Thank you.
