Kalibr is a toolbox that solves the following calibration problems:
- Multiple camera calibration: intrinsic and extrinsic calibration of a camera-systems with non-globally shared overlapping fields of view
- Visual-inertial calibration calibration (camera-IMU): spatial and temporal calibration of an IMU w.r.t a camera-system
- Rolling Shutter Camera calibration: full intrinsic calibration (projection, distortion and shutter parameters) of rolling shutter cameras
Please find more information on the wiki pages of this repository.
For questions or comments, please open an issue on Github.
