How to use MMAUD V1 dataset? (all DSBCAN labels are 0 in my method)

[hxlei0827]

hi, I used "MMAUD V1 Rooftop Simple" from "https://github.com/ntu-aris/MMAUD", and tried to follow your trajectory estimation part. May I know how you deal with the V1 datasets into train and val set for LSTM training? My method is to sample one data from every four data from each type of UAV in V1 dataset to build my val set. However, I got stuck at "building_lidar_360_dataset.py“, because I found all the labels generated from DBSCAN are 0, and the feature set generated from this python file seems correct. May I know if it is due to the inappropriate separation of the train and val dataset?

I visualize all the windows(20 frames per window), we can see the uav's trajectory. But why all the labels generate by DBSCAN are 0?

The code logic is simple, just accumulate several frames and use dbscan to cluster the accumulated point clouds. You can visualise the cluster results to check your problem.
