Vehicle localisation and deep model for automatic calibration of monocular camera in expressway scenes

IET Intelligent Transport Systems, 2022
The authors present a fully automatic method for camera calibration in expressway scenes and vehicle localisation on curved roads. Our approach does not depend on specific targets or a priori information and adapts to a wide range of variations in road ...

Research on Calibration Algorithm of Camera and LiDAR for Transport Vehicles in Open-pit Mines

Kongzhi Yu Xinxi Jishu, 2022
In the intelligent driving system of transport vehicles in open-pit mines, the data fusion of camera and LiDAR plays a vital role in the detection, recognition and tracking of obstacles. Aiming at the problem of camera and LiDAR spatial coordinate unity,

Photogrammetry requirements for digital camera calibration applying Tcc and MatLab software

Geodesy and Cartography, 2012
The result of photogrammetry is a digital object or terrain images on the plane or in three-dimensional space. Precise data on the object is photocopied by a professional digital camera equipped with the calibrated system of optical lens (evaluation of ...

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.

A Pointing Solution for the Medium Size Telescopes for the Cherenkov Telescope Array

, 2016
An important aspect of the calibration of the Cherenkov Telescope Array is the pointing, which enables an exact alignment of each telescope and therefore allows to transform a position in the sky to a point in the plane of the Cherenkov camera and vice ...

Self-Calibration of Cameras with Euclidean Image Plane in Case of Two Views and Known Relative Rotation Angle

, 2018
The internal calibration of a pinhole camera is given by five parameters that are combined into an upper-triangular $3\times 3$ calibration matrix.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

Molecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Hybrid Focal Stereo Networks for Pattern Analysis in Homogeneous Scenes

, 2013
In this paper we address the problem of multiple camera calibration in the presence of a homogeneous scene, and without the possibility of employing calibration object based methods.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

FEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.
