Geometrical DMO Calibration and Spatial Dealiasing

Proceedings, 1995
Irregular acquisition geometry is inevitable due to obstacles and cable feathering in 3-D marine surveys and access limitations in 3-D land surveys. The irregularities will damage the fidelity of seismic images, unless they are properly handled in the processing. DMO in particular, must take account of the actual geometry.

SIMBIO-SYS/STC stereo camera calibration: Geometrical distortion

Review of Scientific Instruments, 2019
The STereo imaging Channel (STC) is the first push-frame stereo camera on board an European Space Agency (ESA) satellite, i.e., the ESA-Japan Aerospace eXploration Agency mission BepiColombo. It was launched in October 2018, and it will reach its target, Mercury, in 2025. The STC main aim is to provide the global three-dimensional reconstruction of the

Flexible geometrical calibration for fringe-reflection 3D measurement

Optics Letters, 2012
System geometrical calibration is a challenging task in fringe-reflection 3D measurement because the fringe displayed on the LCD screen does not lie within the camera's field of view. Commonly, a flat mirror with markers can accomplish system geometrical calibration.

Geometric calibration of the circle-plus-arc trajectory

Physics in Medicine and Biology, 2007
In this paper, a novel geometric calibration method for C-arm cone-beam scanners is presented which allows the calibration of the circle-plus-arc trajectory. The main idea is the separation of the trajectory into two circular segments (circle segment and arc segment) which are calibrated independently.

Camera Calibration: Geometric and Colorimetric Correction

2013
This chapter analyzes camera calibration from a geometric and colorimetric perspective. The first part of the chapter introduces the mathematical model that describes a camera such as position, orientation, focal, as well as its applications such as 3D reconstructions.
