DIGITAL CAMERA CALIBRATION USING IMAGES TAKEN FROM AN UNMANNED AERIAL VEHICLE [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 For calibrating the camera, an accurate determination of the interior orientation parameters is needed. For more accurate results, the calibration images should be taken under conditions that are similar to the field samples.

Camera Calibration from Symmetry [PDF]
, 2000 This paper addresses the problem of calibrating a pinhole camera from images of a surface of revolution. Camera calibration is the process of determining the intrinsic or internal parameters (i.e. aspect ratio, focal length and principal point) of a camera, and is important for both motion estimation and metric reconstruction of 3D models.

Effect of terahertz irradiation on DNA damage repair in living cells
FEBS Open Bio, EarlyView.We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Multi‐camera traffic scene mosaic based on camera calibration
IET Computer Vision, 2021 Recently, the traffic application based on vision in the single traffic‐monitoring scene has been widely studied and developed. However, cross‐regional research is still in its infancy.

A Novel and Simplified Extrinsic Calibration of 2D Laser Rangefinder and Depth Camera
Machines, 2022 It is too difficult to directly obtain the correspondence features between the two-dimensional (2D) laser-range-finder (LRF) scan point and camera depth point cloud, which leads to a cumbersome calibration process and low calibration accuracy. To address

Towards dynamic camera calibration for constrained flexible mirror imaging [PDF]
, 2008 Flexible mirror imaging systems consisting of a perspective camera viewing a scene reflected in a flexible mirror can provide direct control over image field-of-view and resolution. However, calibration of such systems is difficult due to the vast range
