Multi-lens, Multi-camera Calibration of Sony Alpha NEX 5 Digital Cameras
نویسنده
چکیده
This paper describes close-range calibrations of multiple Sony Alpha NEX 5 consumer digital cameras with multiple interchangeable lenses. The standard physical parameter set and a standard parameter set with affinity and orthogonality terms are tested with both block-invariant and photo-invariant principal point parameters. The impact of the parameter sets is analysed to determine the effectiveness of the inclusion of these parameters in reducing systematic errors. The parameters are analysed to determine if a lens effect or camera effect is being modelled. Some conclusions are drawn regarding the possible physical sources of the systematic errors.

Metric Capabilities of Low-cost Digital Cameras for Close Range Surface Measurement
This paper examines the potential of low cost digital cameras for close-range surface measurement using feature based image matching methods. This is achieved through extracting digital elevation models (DEMs) and comparing accuracies between three low-cost consumer grade digital cameras (Sony DSC-P10, Olympus C3030, Nikon Coolpix 3100) and the proven Kodak DCS460. Surprisingly, the tests revea...

متن کاملA Flexible, Generic Photogrammetric Approach to Zoom Lens Calibration
Compared with prime lenses, zoom lenses have inherent advantages in terms of operational flexibility. Zoom lens camera systems have therefore been extensively adopted in computer vision where precise measurement is not the primary objective. However, the variation of intrinsic camera parameters with respect to zoom lens settings poses a series of calibration challenges that have inhibited wides...
متن کاملA Semi-Automatic Image-Based Close Range 3D Modeling Pipeline Using a Multi-Camera Configuration
The generation of photo-realistic 3D models is an important task for digital recording of cultural heritage objects. This study proposes an image-based 3D modeling pipeline which takes advantage of a multi-camera configuration and multi-image matching technique that does not require any markers on or around the object. Multiple digital single lens reflex (DSLR) cameras are adopted and fixed wit...
