Coordinate transformation and its uncertainty under consideration of a non-orthogonal coordinate base [PDF]

, 2021
Nanopositioning and nanomeasuring machines are 3D coordinate measuring systems with nanometer precision at measurement volumes in the cubic centimeter range. The coordinate base is formed by an interferometer system with a common mirror corner.

ALGORITHM AND APPLICATION DEVELOPMENT FOR PRECISE AND ACCURATE TRANSFORMATION OF LIDAR POINT CLOUDS INTO NATIONAL COORDINATE SYSTEMS OF ROMANIA USING OFFICIAL EQUATIONS AND QUASIGEOID MODEL [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
The LiDAR point clouds are usually processed in Universal Transvers Mercator projection. The transformation to a national coordinate system is frequently made with low accuracy with the help of the generic transformation implemented in the actual ...

Tensor Decompositions and Their Properties

Mathematics, 2023
In the present paper, we study two different approaches of tensor decomposition. The first part aims to study some properties of tensors that result from the fact that some components are vanishing in certain coordinates.

The impact of data normalization on 2D coordinate transformation using GRNN [PDF]

Geodetski Vestnik, 2019
The coordinate transformation has always been a hot topic in the field of geodesy. The artificial neural network (ANN) has been used as an alternative tool to determine the relationship between any two coordinate systems.

The application of an artificial neural network for 2D coordinate transformation

Journal of Intelligent Systems, 2022
Clark1880, WGS1984, and ITRF08 are the reference systems used in Iraq. The ITRF08 and WGS84 represent the global reference frames. In the majority of instances, the transformation from one coordinate system to another is required.

Research on the Hand–Eye Calibration Method of Variable Height and Analysis of Experimental Results Based on Rigid Transformation

Applied Sciences, 2022
In view of the phenomenon that camera imaging will appear large up close and small from afar in the eye-to-hand hand-calibration system, one hand–eye calibration is carried out.

Novel antenna concepts via coordinate transformation [PDF]

, 2013
Coordinate transformation is an emerging field which offers a powerful and unprecedented ability to manipulate and control electromagnetic waves. Using this tool, we demonstrate the design of novel antenna concepts by tailoring their radiation properties.

A coordinate vector correction method toimprove the traditional affine transformationgraphic digitised cadastral map

, 2014
Parameter coordinate transformation regards the whole transformation region under the samecondition for coordinate adjustment. However, the practical errors and ideal corrected values arenot ‘individually’ discussed.
