Automated Target-free Camera Calibration
Automatic camera calibration is now a well-established procedure. The process generally involves photographing a target array to form a network of images in a geometric configuration suited to self-calibration. Full automation can be implemented if coded targets are employed, as these provide initial image point correspondences necessary for network exterior orientation. While the use of coded ...
متن کاملA European Network on Digital Camera Calibration
Background The need of a camera calibration is a fundamental requirement in the context of photogrammetric data processing. For airborne sensors this calibration is typically realized under well controlled laboratory conditions. In this case, special calibration devices are used to determine the internal camera characteristics with sufficient accuracy. Using such calibration facilities, the dis...
متن کاملComplete Calibration of a Multi-camera Network
We describe a calibration procedure for a multi-camera rig. Consider a large number of synchronized cameras arranged in some space, for example, on the walls of a room looking inwards. It is not necessary for all the cameras to have a common field of view, as long as every camera is connected to every other camera through common fields of view. Switching off the lights and waving a wand with an...
متن کاملCalibration of a Hybrid Camera Network
Visual surveillance using a camera network has imposed new challenges to camera calibration. An essential problem is that a large number of cameras may not have a common field of view or even be synchronized well. We propose to use a hybrid camera network that consists of catadioptric and perspective cameras for a visual surveillance task. The relations between multiple views of a scene capture...
متن کاملEuroSDR network on Digital Camera Calibration
This paper documents the status of the actual Phase 1 of the EuroSDR project on “Digital Camera Calibration”. This project was officially installed in October 2003 during the 103 EuroSDR Science and Steering Committee Meetings. Up to now about 35 experts from industry, camera manufacturers, software developers, research and system users already joined this calibration network. Some general rema...
