3D Vision by Using Calibration Pattern with Inertial Sensor and RBF Neural Networks
Sensors, 2009 Camera calibration is a crucial prerequisite for the retrieval of metric information from images. The problem of camera calibration is the computation of camera intrinsic parameters (i.e., coefficients of geometric distortions, principle distance and ...

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 ...

Improvements to Target-Based 3D LiDAR to Camera Calibration
IEEE Access, 2020 The rigid-body transformation between a LiDAR and monocular camera is required for sensor fusion tasks, such as SLAM. While determining such a transformation is not considered glamorous in any sense of the word, it is nonetheless crucial for many modern ...
