An Autonomous Positioning Method of Tube-to-Tubesheet Welding Robot Based on Coordinate Transformation and Template Matching

IEEE Robotics and Automation Letters, 2021
In order to change the positioning method “teach-playback” for tube-to-tubesheet welding by robots, this letter proposes an autonomous positioning method based on coordinate transformation and template matching. The coordinate trans-formation between the

Optical coordinate transformations

Applied Optics, 1992
A novel technique for designing holographic optical elements that can perform general types of coordinate transformation is presented. The design is based on analytic ray-tracing techniques for finding the grating vector of the element, from which the holographic grating function is obtained as a solution of a Poissonlike equation. The grating function

A Multiobjective Evolutionary Algorithm Based on Coordinate Transformation

IEEE Transactions on Cybernetics, 2019
In this paper, a novel multiobjective evolutionary algorithm (MOEA/CT) is proposed to better manage convergence and distribution of solutions when MOEAs are used for solving multiobjective optimization problems. The coordinate transformation strategy, an

Uncertainties evaluation of coordinate transformation parameters in the large-scale measurement for aircraft assembly

Sensor Review, 2018
Purpose For the measurement of large-scale components in aircraft assembly, the evaluation of coordinate transformation parameters between the coordinate frames of individual measurement systems to the assembly frame is an essential task, which is ...

Coordinates and coordinate transformations

1996
Abstract In the discussion of variational methods in the previous chapter we contrasted the Newtonian emphasis on the motion of particles with the Lagrangian idea of an invariant system property called the action, which has a stationary value under small arbitrary displacements of the coordinates and their associated velocities. Since

Coordinate transformation with variable number of parameters

Survey Review, 2018
Similarity transformation model does not provide a satisfactory solution for non-uniformly deformed systems because it allows only for a uniform scale and right angles.

Coordinate transformation resonators

Applied Physics Letters, 2018
2-D coordinate transformation resonators based on transformation electromagnetics are proposed. The proposed resonators are with the shapes and effective media parameters coordinate transformed from arbitrary different shaped resonators.

Transformation to Rotating Coordinates

Nature, 1970
IN the treatment of problems involving rotating coordinate frames one of two types of viewpoint is conventionally adopted. The assumption may either be made that the use of principles familiar in special relativity can be extended to the rotating coordinate case, or a general-relativistic treatment may be used, with use of an explicit coordinate ...
