In-vivo pan/tilt endoscope with integrated light source [PDF]

open access: yes, 2007
Endoscopic imaging is still dominated by the paradigm of pushing long sticks into small openings. This approach has a number of limitations for minimal access surgery, such as narrow angle imaging, limited workspace, counter-intuitive motions and ...

Lateral chromatic aberration correction method and lens design feedback for dynamic optical tilt

open access: yesResults in Optics, 2021
A method of generating lateral chromatic aberration correction factor (CACF) during lens development is presented. This CACF will be able to feedback to lens designer whether the design will work when tilt Optical Image Stabilization (OIS) compensation ...

A Novel Monocular Vision Technique for the Detection of Electric Transmission Tower Tilting Trend

open access: yesApplied Sciences, 2022
Transmission lines are primarily deployed overhead, and the transmission tower, acting as the fulcrum, can be affected by the unbalanced force of the wire and extreme weather, resulting in the transmission tower tilt, deformation, or collapse.

STUDY OF DIGITAL CAMERA CALIBRATION ON A FLAT TEST OBJECT [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
The paper presents a method for calibration of digital cameras based on the use of a flat test object. The main distinctive feature of this method is that the camera is fixed and does not change its position in space.

Reproducible Evaluation of Pan-Tilt-Zoom Tracking [PDF]

open access: yes, 2015
Tracking with a Pan-Tilt-Zoom (PTZ) camera has been a research topic in computer vision for many years. However, it is very difficult to assess the progress that has been made on this topic because there is no standard evaluation methodology.

Pan–Tilt IR Scanning Method for the Remote Measurement of Mean Radiant Temperatures at Multi-Location in Buildings

open access: yesRemote Sensing, 2021
The mean radiant temperature (MRT) is an indicator for evaluating the radiant heat environment near occupants and is determined by the radiant heat exchange between the occupants and their surroundings.

A distributed camera system for multi-resolution surveillance [PDF]

open access: yes, 2009
We describe an architecture for a multi-camera, multi-resolution surveillance system. The aim is to support a set of distributed static and pan-tilt-zoom (PTZ) cameras and visual tracking algorithms, together with a central supervisor unit.

Correction for Camera Roll in a Perspectively Distorted Image: Cases for 2 and 3 point perspectives

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2007
We propose a method for correction of camera roll in a perspectively distorted image. Here we employ the rectification of the horizon line formed from the vanishing points in order to bring back the image rotation caused from the camera roll.
