Different calibration files #8

Closed amineboujnah-dev closed 1 year ago

amineboujnah-dev commented 1 year ago

Hello, can someone explain why the kitti dataset contains different calibration files with different values ? As far as i know the calibration is made once since the position of sensors is known.

  1. There are different scenes in the KITTI dataset.
  2. The pose of the camera is also called the extrinsics of the camera (Camera Extrinsics). Compared with the constant internal parameters, the external parameters will change with the camera movement
