Lifetime from: 2013 Short description: Automatic calibration of ominidirectional, perspective camera and lidar images is important for 3D model construction, robot navigation and environment mapping. The proposed methodology is without any specific constraint on source of data and the calibration can be performed using a single pair of lidar-camera image without any implicit correspondence betw...

Online C-arm calibration procedure is an important issue for the use of this image modality intraoperatively in the surgical rooms. Automatic detection of the images center and radius is one of the key step for camera calibration. In the current approaches, this is measured manually, and the geometrical measurements are supplied as parameters to the calibration algorithm. In this paper, a metho...

Intensity images acquired with range imaging instruments can be used in the future for various applications, e.g. face recognition, assisting blind people in travelling and walking, automatic robotic vision, rendering 3D models and improving automatic recognition of objects. For the intensity information to be usable, it needs to be radiometrically calibrated. In this paper we propose the first...

We describe a method for determining a ne and metric calibration of a camera with unchanging internal parameters undergoing planar motion. It is shown that a ne calibration is recovered uniquely, and metric calibration up to a two fold ambiguity. The novel aspects of this work are: rst, relating the distinguished objects of 3D Euclidean geometry to xed entities in the image; second, showing tha...
