A Review of RGB-D Camera Calibration Methods [PDF]
Journal of Geodesy and Geoinformation Science, 2021 RGB-D camera is a new type of sensor, which can obtain the depth and texture information in an unknown 3D scene simultaneously, and they have been applied in various fields widely. In fact, when implementing such kinds of applications using RGB-D camera,

ANALYSIS OF ORIENTATION ACCURACY OF AN UAV IMAGE ACCORDING TO CAMERA CALIBRATION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Utilization of an UAV is increasing because of its easy operation and time saving advantages. Compared with other remote sensing platforms, the biggest difference of a small UAV is the unstable flight attitude due to platform stability. UAVs are equipped

Camera Calibration Through Camera Projection Loss
ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022 Camera calibration is a necessity in various tasks including 3D reconstruction, hand-eye coordination for a robotic interaction, autonomous driving, etc. In this work we propose a novel method to predict extrinsic (baseline, pitch, and translation), intrinsic (focal length and principal point offset) parameters using an image pair.

Catadioptric camera calibration [PDF]
Proceedings of the Seventh IEEE International Conference on Computer Vision, 1999 Catadioptric systems are realizations of omnidirectional vision through mirror-lens combinations. Designs preserving the uniqueness of an effective viewpoint have recently gained attraction. We present here a novel approach for estimating the intrinsic parameters of a well-known catadioptric system consisting of a paraboloid mirror and an orthographic ...
