Some infrastructure pcd file missing in the cooperative label_world

[smallscientist1]

When using this dataset, I found that in ./cooperative-vehicle-infrastructure/cooperative/data_info.json file, the pcd file in "infrastructure_pointcloud_path" attribute sometimes doesn't exist at all. Is this a problem of the dataset?

This is normal. We associate vehicle-side and infrastructure-side frames according to a certain time difference constraint. There are some vehicle-side frames at the edge of the clip without corresponding infrastructure-side frames
