SUB-CAMERA CALIBRATION OF A PENTA-CAMERA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Abstract. Penta cameras consisting of a nadir and four inclined cameras are becoming more and more popular, having the advantage of imaging also facades in built up areas from four directions. Such system cameras require a boresight calibration of the geometric relation of the cameras to each other, but also a calibration of the sub-cameras.

Camera Calibration Through Camera Projection Loss

open access: yesICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022
Camera calibration is a necessity in various tasks including 3D reconstruction, hand-eye coordination for a robotic interaction, autonomous driving, etc. In this work we propose a novel method to predict extrinsic (baseline, pitch, and translation), intrinsic (focal length and principal point offset) parameters using an image pair.

Separating true range measurements from multi-path and scattering interference in commercial range cameras [PDF]

open access: yes, 2011
Time-of-flight range cameras acquire a three-dimensional image of a scene simultaneously for all pixels from a single viewing location. Attempts to use range cameras for metrology applications have been hampered by the multi-path problem, which causes ...

Gender differences in responses to speed cameras: Typology findings and implications for road safety [PDF]

open access: yes, 2006
Automated speed cameras in England and Wales have become a very common means of enforcement of speed limit breaches in most police force areas, but they are not without controversy despite the majority of public opinion behind them. Research in the mid-

The gigavision camera [PDF]

open access: yes2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009
We propose a new image device called gigavision camera. The main differences between a conventional and a gigavision camera are that the pixels of the gigavision camera are binary and orders of magnitude smaller. A gigavision camera can be built using standard memory chip technology, where each memory bit is designed to be light sensitive.

Technical and technical aspects used to monitor folk festivals using 4K cameras technology [PDF]

open access: yesJournal of Architecture, Art & Humanistic Science, 2023
Conclusion:There is no room for doubt about the value and importance of using 4K cameras and their lenses in documenting people’s festivals, which in turn show folklore topics in a high-resolution and more clear detail and landmarks than it was, as he ...

SR-4000 and CamCube3.0 Time of Flight (ToF) Cameras: Tests and Comparison [PDF]

open access: yes, 2012
In this paper experimental comparisons between two Time-of-Flight (ToF) cameras are reported in order to test their performance and to give some procedures for testing data delivered by this kind of technology.

Cameras Viewing Cameras Geometry

open access: yesCoRR, 2019
A basic problem in computer vision is to understand the structure of a real-world scene given several images of it. Here we study several theoretical aspects of the intra multi-view geometry of calibrated cameras when all that they can reliably recognize is each other.

Stable stitching method for stereoscopic panoramic video

open access: yesCAAI Transactions on Intelligence Technology, 2018
This paper proposes a stable method of generating a stereoscopic panoramic video with the omnidirectional stereo (ODS) format. Different from the traditional image stitching method which can only be applied to generate a monocular panorama, we adopt an ...

Rosette‐scan tomographic single‐pixel imager

open access: yesElectronics Letters, 2023
Spin‐scan tomographic scanning imagers utilise a reticle with a fixed number of thin slits and nutating optics, and have produced images and video at both infrared and optical wavelengths.
