Calibration of panoramic cameras with coded targets and a 3D calibration field
The aim of this paper is to present results achieved with a 3D terrestrial calibration field, designed for calibrating digital cameras and omnidirectional sensors. This terrestrial calibration field is composed of 139 ARUCO ...
Calibration of a catadioptric omnidirectional vision system with conic mirror
Omnidirectional vision systems that enable 360° imaging have been widely used in several research areas, including close-range photogrammetry, which allows the accurate 3D measurement of objects. To achieve accurate results ...
A low cost structured light system
The aim of this paper is to present the current development status of a low cost system for surface reconstruction with structured light. The acquisition system is composed of a single off-the-shelf digital camera and a ...
Generating virtual images from oblique frames
Image acquisition systems based on multi-head arrangement of digital camerasare attractive alternatives enabling a larger imaging area when compared to a single framecamera. The calibration of this kind of system can be ...

Robust Extrinsic Camera Calibration from Trajectories in Human-Populated Environments
(Revista Computación y Sistemas; Vol. 16 No. 1, 2012-03-05)
Abstract. This paper proposes a novel robust approach to perform inter-camera and ground-camera calibration in the context of visual monitoring of human-populated areas. By supposing that the monitored agents evolve on ...
A tool for controlling accelerometers. Secondary calibration data
(Elsevier B.V., 2013-09-01)
Vibration monitoring requires acceleration transducers capable of providing data with high precision. Accelerometers are the most frequently used vibration transducers. Their calibration plays an important role in measuring ...
Simple and efficient method for calibration of a camera and 2D laser rangefinder
In the last few years, the integration of cameras and laser rangefinders has been applied to a lot of researches on robotics, namely autonomous navigation vehicles, and intelligent transportation systems. The system based ...
Absolute calibration of a large-diameter light source
(Iop Publishing, 2013-05-23)
A method of absolute calibration for large aperture optical systems is presented, using the example of the Pierre Auger Observatory fluorescence detectors. A 2.5 m diameter light source illuminated by an ultra-violet light ...
