Boreas

Notes on the Dataset
- There are two different routes, but one route is only followed once in one of the (test) sequences.
- The route of the additional Boreas-Objects-V1 dataset does not seem to correspond to the other sequences.
- For 10 epochs, the ground thruth trajectory has not been released to facilitate a comparable, public benchmark.
- The quality of the point clouds strongly depends on the weather during acquisition.
- The download website depicts the estimated download size and calculates with 100 GB per sequence. Many sequences actually have a lower size (~80 GB).
- In the pip version of pyboreas (the accompanying Python package for the dataset), the odom_train split erroneously contains `boreas-2021-04-29-15-55`, which however has no odometry data available.
