Dataset for Spatiotemporal Registration for Event-based Visual Odometry

The RobotEvt dataset contains sequences under different motion models, speeds and brightness from a static scene, specifically

UR5 robot arm with DAVIS 240C event camera, and sample APS image and event image captured with our setup.

This dataset were recored with a DAVIS240C, attatched on the endpoint of a UR5 robot arm. Ground truth were generated from the UR5 robot arm.

Dataset format!

Events, raw images and IMU measurements are stored in the rosbag file.

Ground truth are provided with a txt file, where the poses are represented using rotation matrix and translation. One pose per line (timestamp r11 r12 r13 r21 r22 r23 r31 r32 r33 t1 t2 t3) .

calibration of camera is provided with a txt file (calib.txt), where the first four digits represent the camera intrinic (fx fy cx cy) and the rest digits represent the distortion model.

Download links

Download link for Pure Rotation sequences can be downloaded here, which contains the measurement of events, raw images and IMU. More sequences with full rigid motion and higher resolution generated using Prophesee cameras will be released soon.
