End-to-End Camera Calibration for Broadcast Videos
Computer Vision and Pattern Recognition, 2020The increasing number of vision-based tracking systems deployed in production have necessitated fast, robust camera calibration. In the domain of sport, the majority of current work focuses on sports where lines and intersections are easy to extract, and

Automatic LiDAR-Camera Calibration of Extrinsic Parameters Using a Spherical Target
IEEE International Conference on Robotics and Automation, 2020This paper investigates a novel calibration process of devices with different modalities, which is a critical step of computer vision applications. We propose a fully automatic extrinsic calibration of a LiDAR-camera system.

Proceedings of International Symposium on Computer Vision - ISCV, 2002
A close range camera calibration scheme can be divided into a static scheme and a dynamic scheme. The static scheme is used to calibrate single camera by applying bundle adjustment on multiple digitized images of a calibration block. The dynamic scheme calibrates the stereo cameras using camera parameters derived from the static calibration even after ...

Multichannel camera calibration
SPIE Proceedings, 2013For the latest computer vision applications, it becomes more and more popular to take advantage of multichannel cameras (RGB cameras, etc.) to obtain not only gray values but also color information of pixels. The currently most common approach for multichannel camera calibration is the straightforward application of methods developed for calibration

Camera calibration using synthetic random speckle pattern and digital image correlation
, 2020Accurate camera calibration is of fundamental importance to various vision-based 3D metrological techniques. Despite camera calibration methods using regular planar calibration targets (e.g., checkerboard or circular pattern) have been widely adopted ...

Camera calibration denotes the task of estimating the projective mapping between 3D world and the camera image plane. Most of the modern cameras have multiple image and video acquisition modes, which differ in image resolution, field of view or aspect ratio.

Deep Single Image Camera Calibration With Radial Distortion
Computer Vision and Pattern Recognition, 2019Single image calibration is the problem of predicting the camera parameters from one image. This problem is of importance when dealing with images collected in uncontrolled conditions by non-calibrated cameras, such as crowd-sourced applications. In this

Multi-camera calibration for accurate geometric measurements in industrial environments
Measurement, 2019Accurate camera calibration is a challenging task required for 3D reconstruction sensors. In structured light sensors based on laser line projection, it is necessary to determine the position and orientation of the camera relative to the laser plane. The

The single camera measurement system can't obtain all the surface information of the object limited by the field of view, thus it can't achieve complete measurement of the object. Multi-camera system can overcome this difficulty.
