Discrete Camera Autocalibration Consistent with the Frame of the Robotic Pan-tilt Basis
Procedia Technology, 2014 AbstractIn this paper we approach the problem of calibrating topologically a discrete camera mounted on a robotic pan-tilt basis. In particular this work is focused in choosing the coordinate system of the camera consistently with the basis. The topological calibrating methodology of the sensor is based on multidimensional scaling (MDS).

Autocalibration of a projector-camera system
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2005This paper presents a method for calibrating a projector-camera system that consists of multiple projectors (or multiple poses of a single projector), a camera, and a planar screen. We consider the problem of estimating the homography between the screen and the image plane of the camera or the screen-camera homography, in the case where there is no ...

Globally convergent autocalibration using interval analysis
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2004 We address the problem of autocalibration of a moving camera with unknown constant intrinsic parameters. Existing autocalibration techniques use numerical optimization algorithms whose convergence to the correct result cannot be guaranteed, in general ...

Hand-eye autocalibration of camera positions on vehicles
13th International IEEE Conference on Intelligent Transportation Systems, 2010This paper introduces an approach to extrinsic autocalibration of vehicle mounted cameras for Bird's Eye View applications. We extend existing self-calibration methods by estimation of two position parameters while assuming the camera height to be known.

Online Camera-Gyroscope Autocalibration for Cell Phones
IEEE Transactions on Image Processing, 2014The gyroscope is playing a key role in helping estimate 3D camera rotation for various vision applications on cell phones, including video stabilization and feature tracking. Successful fusion of gyroscope and camera data requires that the camera, gyroscope, and their relative pose to be calibrated. In addition, the timestamps of gyroscope readings and

Autocalibration of lidar and optical cameras via edge alignment
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016We present a new method for joint automatic extrinsic calibration and sensor fusion for a multimodal sensor system comprising a LIDAR and an optical camera. Our approach exploits the natural alignment of depth and intensity edges when the calibration parameters are correct.

Autocalibration & 3D reconstruction with non-central catadioptric cameras
Proceedings of the 2004 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2004. CVPR 2004., 2004We present a technique for modeling non-central catadioptric cameras consisting of perspective cameras and curved mirrors. The real catadioptric cameras have to be treated as non-central cameras, since they do not possess a single viewpoint. We present a method for solving the correspondence problem, auto-calibrating cameras, and computing a 3D metric ...
