Nominal values of the camera mode and lens model, not a calibration of this individual camera. The principal point is assumed at the image center.

Straight lines on a plane in front of the camera, every 10° of viewing angle, projected with these parameters (center lines bold). Without lens distortion they stay straight, a fisheye lens bends them.

Classification sensitivity

...

A higher sensitivity detects more potential belt damages, but also produces more false alarms. A lower sensitivity reports only clear cases. "Re-classify" recomputes the report's detections with the selected sensitivity in the background.

Rejected detections

Detections you deleted or moved stay rejected: a re-classification will not bring them back, unless it is now markedly more confident. Restore a detection to show it again.
