 > - [x] **Calibration:** Convert Vicon [.xcp calibration file](https://montrealrobotics.ca/diffcvgp/assets/papers/7.pdf).
 > - [x] **Calibration:** Easier and clearer calibration procedure: separate intrinsic and extrinsic parameter calculation, edit corner detection if some are wrongly detected (or not visible). 
 > - [x] **Calibration:** Possibility to evaluate extrinsic parameters from cues on scene.
-> - [ ] **Calibration:** Track extrinsics reference points frame by frame for calibration of moving cameras.
