CRUW devkit

Package cruw-devkit is a useful toolkit for the CRUW dataset including sensor configurations, sensor calibration parameters, the mapping between RF image coordinates (in pixel) and radar's bird's-eye view coordinates (in meters), metadata, visualization tools, etc. More components are still in the developing phase.

Please refer to our dataset website for more information about the CRUW Dataset.

Annotation Format

ROD2021 Dataset

Each training sequence (40 training sequences in total) has an txt object annotation file. The annotation format for the training set (each line in the txt files):

  frame_id range(m) azimuth(rad) class_name
  ...

General CRUW Dataset

For each sequence, a json file is provided as annotations:
