Dataset Format

Each sequence would provide several ‘sensors’ along with their sensor.yaml file that specifies sensor type, intrinsic and extrinsic parameters. The sensor measurements(or measurement indices, for camera) is stored in data.csv . In our case, both camera and IMU data would be provided. The vicon and groundtruth is also treated like a ‘sensor’. Here is an example:
