A Flexible New Technique for Camera Calibration
نویسنده
چکیده
The paper proposes a flexible new technique to easily calibrate a camera. The technique only requires the camera to observe a planar pattern shown at a few (at least two) different orientations. Either the camera or the planar pattern can be freely moved. The motion need not be known. Radial lens distortion is modeled. The proposed procedure consists of a closed-form solution, followed by a nonlinear refinement based on the maximum likelihood criterion. The author provides both computer simulation and real data to test the proposed technique, and very good results have been obtained. Compared with classical techniques that use expensive equipment, the proposed technique is easy to use and flexible. It advances 3D computer vision one step from laboratory environments to real world use.

Calibration of Multi-camera Systems Using Planar Patterns
A new calibration algorithm for multi-camera systems using planar reference patterns is proposed. The algorithm is an extension of Zhang’s flexible calibration technique to the cases with multiple cameras. Rigid displacements between cameras are recovered as well as intrinsic camera parameters only by showing the cameras a model plane with known reference patterns placed at several locations. T...
متن کاملNew approach for calibration of pixelated scintillation detectors of intraoperative gamma cameras
Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...
متن کاملPlanar Conic Based Camera Calibration
Inspired by the technique proposed by Zhang in [13], we proposed a new camera calibration technique, which only requires observing three or more planar con-centric conics at a few (at least two) different orientations. All computations involved are linear matrix manipulations. Compared with the classical techniques where an expensive calibration pattern is commomly used, our technique is easy t...
متن کاملCalibration of Non-Conventional Imaging Systems
This thesis investigates the calibration of cameras that do not conform to the standard pinhole-plus-distortion camera model. The ability to calibrate such camera systems is essential for the development of new, non-conventional, camera types. The major contributions of the thesis are the development of calibration algorithms for both central catadioptric cameras and non-central flexible mirror...
متن کاملA Flexible New Technique for Camera Calibration
We propose a flexible new technique to easily calibrate a camera. It is well suited for use without specialized knowledge of 3D geometry or computer vision. The technique only requires the camera to observe a planar pattern shown at a few (at least two) different orientations. Either the camera or the planar pattern can be freely moved. The motion need not be known. Radial lens distortion is mo...
