Prepare Waymo Open Dataset.

We provide the example scenes here. You can directly download the data and skip the following steps for a quick start.

Download the training and validation set of Waymo Open Dataset.

We provide the split file following EmerNeRF. You can refer to this document for download details.

Preprocess the data

Download the tracking predictions on validation set, We provide the processed results here.

Preprocess the example scenes

python script/waymo/waymo_converter.py --root_dir TRAINING_SET_DIR --save_dir SAVE_DIR --split_file script/waymo/waymo_splits/demo.txt --segment_file script/waymo/waymo_splits/segment_list_train.txt

Preprocess the experiment scenes

python script/waymo/waymo_converter.py --root_dir VALIDATION_SET_DIR --save_dir SAVE_DIR --split_file script/waymo/waymo_splits/val_dynamic.txt --segment_file script/waymo/waymo_splits/segment_list_val.txt
--track_file TRACKER_PATH

Generating LiDAR depth

python script/waymo/generate_lidar_depth.py --datadir DATA_DIR

Generating sky mask

Install GroundingDINO following this repo and download SAM checkpoint from this link.

python script/waymo/generate_sky_mask.py --datadir DATA_DIR --sam_checkpoint SAM_CKPT

Prepare Custom Dataset.

TODO

Training

python train.py --config configs/xxxx.yaml

Training on example scenes

bash script/waymo/train_waymo_expample.sh

Training on experiment scenes

bash script/waymo/train_waymo_exp.sh

Rendering

python render.py --config configs/xxxx.yaml mode {evaluate, trajectory}

Rendering on example scenes

bash script/waymo/render_waymo_expample.sh

Rendering on experiment scenes

Visualization

You can convert the scene at one certain frame into the format that can be viewed in SIBR_viewers.

python make_ply.py --config configs/xxxx.yaml viewer.frame_id {frame_idx} mode evaluate
