Input:
- Events.
- Camera calibration.
Output:
- Rotational motion of the event camera.
- Local (front-end) and global (back-end) image of warped events (IWEs).
We also release the dataset that we made, see and download it from here. The instructions of running CMax-SLAM on the ECRot datasets can be found here.
