Sensor for In-Motion Continuous 3D Shape Measurement Based on Dual Line-Scan Cameras

The acquisition of three-dimensional surface data plays an increasingly important role in the industrial sector. Numerous 3D shape measurement techniques have been developed. However, there are still limitations and challenges in fast measurement of large-scale objects or high-speed moving objects. The innovative line scan technology opens up new potentialities owing to the ultra-high resolutio...

New 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...

Airborne Pushbroom Line Scan An Alternative to Digital Frame Cameras

Film-Based Line Scanners As mentioned in a previous article published in the July/August 2000 issue of GeoInformatics, the basic idea of an airborne line scanner is not new. One can trace its ancestry back to the shutterless airborne film-based strip cameras of the 1930s, known (after the inventor's name) as Sonne cameras. These were used mainly for highspeed low-level reconnaissance flights ov...

Calibration of Action Cameras for Photogrammetric Purposes

The use of action cameras for photogrammetry purposes is not widespread due to the fact that until recently the images provided by the sensors, using either still or video capture mode, were not big enough to perform and provide the appropriate analysis with the necessary photogrammetric accuracy. However, several manufacturers have recently produced and released new lightweight devices which a...

Calibration of Digital Amateur Cameras

We introduce a novel outlook on the self-calibration task, by considering images taken by a camera in motion, allowing for zooming and focusing. Apart from the complex relationship between the lens control settings and the intrinsic camera parameters, a prior o -line calibration allows to neglect the setting of focus, and to x the principal point and aspect ratio throughout distinct views. Thus...
