Where to get CAD models #2

Closed shubham1810 closed 2 years ago

shubham1810 commented 2 years ago

I am trying to look for the CAD models as per the information on the dataset website but can't find them. Please let me know if it is available yet?

Essentially I want to visualize the scene in the second column from the below image (taken from dataset website)

Thanks!

@shubham1810 the CAD models are distributed as a single PLY file (cad.mesh.ply) included in the same archive where the point clouds are, i.e. mapillary_metropolis_v1_point_clouds.zip. These meshes can be interpreted in the same coordinates system as the other point cloud files, for guidance please refer to the metropolis_crop_point_clouds script.

Note that for now the SDK doesn't include a visualization function for the CAD models, but we are planning to release it as soon as possible.

@ducksoup Thank you for the prompt response! I believe I will be able to test the scripts once #1 is resolved as well.

@ducksoup when I look up the reference image above(from left to right:pointcloud, cad render depth, original img), I do find something: 9

I make some visualization arrows for better understanding. seems the accuray of reconstruction not that high?
