Download pretrained weights for 3DMatch, 3DLoMatch, Odometry KITTI and MVP-RG from GoogleDrive or BaiduDisk (pwd: vr9g
).
We adopt the 3DMatch and 3DLoMatch provided from PREDATOR, and download it here [936.1MB]. Unzip it, then we should get the following directories structure:
| -- indoor
| -- train (#82, cats: #54)
| -- 7-scenes-chess
| -- 7-scenes-fire
| -- ...
| -- sun3d-mit_w20_athena-sc_athena_oct_29_2012_scan1_erika_4
| -- test (#8, cats: #8)
| -- 7-scenes-redkitchen
| -- sun3d-home_md-home_md_scan9_2012_sep_30
| -- ...

Download odometry kitti here with [velodyne laser data, 80 GB]
and [ground truth poses (4 MB)]
, then unzip and organize in the following format.

Set an appropriate voxel_size
for your test data. If you want to test on point cloud pair with large amount of points, please set a large voxel_size
according to your data.
