The proposed approach takes as input a LiDAR point cloud, the corresponding monocular image, and the camera calibration matrix K. Instead of directly regress to the calibration parameters, they are obtained maximizing the geometric and photometric consistency of the input images and point clouds. In...
Camera calibrationIn this paper, we present a system for estimating the trajectory of a moving RGB-D camera with applications to building maps of large indoor environments. Unlike the current most researches, we propose a 'feature model' based RGB-D visual odometry system for a computationally-...
After a point cloud has been converted into a three-dimensional representation in a spatial coordinate system, it is still not possible to perform joint calibration with the point cloud image directly. A point cloud image is a three-dimensional spatial map, whereas a camera image is a two-dime...
Accurate geometric camera calibration Overview This repository contains a tool foraccurate geometric camera calibration, i.e., establishing a mapping between image pixels and the pixels' 3D observation directions respectively lines. In particular, it supports calibration withgenericcamera models, which fit...
[42] showed uncertainty-driven 6D pose estimation of objects and scenes from a single RGB image. Feng et al. [43] proposed a hand-eye calibration-free strategy to actively relocate a camera in the same 6D pose by sequentially correcting relative 3D rotation and translation. Nakano [44] ...
The focus setting of the lens will usually be fixed to a chosen value before calibration, as changes of focus usually also affect the focal length. Whereas many film and digital cinematography cameras use a fixed focal length (or “prime”) lens, a typical TV camera is fitted with a zoom...
“calibration” and viewing conditions might be what causes the color issue. However, the color on a computer monitor also looked wrong. Naturally, the photographer decided to dig deeper, and to take a picture of something blue to check the accuracy of the color. The test subject was a ...
An immutable package of settings and outputs needed to capture a single image from the camera device. Contains the configuration for the capture hardware (sensor, lens, flash), the processing pipeline, the control algorithms, and the output buffers. Also contains the list of target Surfaces to...
Omnidirectional Camera Calibration from a Single Low-rank Textured Image 来自 ResearchGate 喜欢 0 阅读量: 32 作者:Y Lin,B Lai 摘要: This paper presents a flexible approach to calibrate an omnidirectional camera from a low-rank textured image, without extracting any point- or line-wise features....
