OPV2V-H dataset

Based on the original OPV2V dataset, we supplemented 16-line, 32-line lidar data for each agent, as well as 4 depth cameras. Annotations will be shared with the original OPV2V, so please download the original OPV2V dataset as well.

  1. Depth Data

    OPV2V-H-depth.zip stores the depth camera data. You can directly uncompress them:

    unzip OPV2V-H-depth.zip

  2. LiDAR Data

    OPV2V-H-LiDAR-partxx is a volume-compressed slice. They store 16-line and 32-line LiDAR data. You can unzip them using

    cat OPV2V-H-LiDAR-part* > OPV2V-H-LiDAR.zip
unzip OPV2V-H-LiDAR.zip

A desired output structure will be 

─ OPV2V_Hetero
