A Simple Integrated Geometrical Error Model for Laser Tracer [PDF]
MATEC Web of Conferences, 2018 Geometrical errors of 2D gimbal mount axes are studied for laser tracer for the sake of realizing rapid detection for numerical control equipment. The high precision reference sphere, which serves as the reflection unit and is set on the base, avoids the influence on measurement accuracy caused by the movements of rotatory axes, and ensures that laser ...

Fixing Geometric Errors on Polygonal Models: A Survey [PDF]
Journal of Computer Science and Technology, 2009 Polygonal models are popular representations of 3D objects. The use of polygonal models in computational applications often requires a model to properly bound a 3D solid. That is, the polygonal model needs to be closed, manifold, and free of self-intersections.

Overviews of Optimization Techniques for Geometric Estimation [PDF]
, 2013 We summarize techniques for optimal geometric estimation from noisy observations for computer vision applications. We first discuss the interpretation of optimality and point out that geometric estimation is different from the standard statistical ...

Measurement system and model for simultaneously measuring 6DOF geometric errors
Optics Express, 2017 A measurement system to simultaneously measure six degree-of-freedom (6DOF) geometric errors is proposed. The measurement method is based on a combination of mono-frequency laser interferometry and laser fiber collimation. A simpler and more integrated optical configuration is designed.

Computing a Compact Spline Representation of the Medial Axis Transform of a 2D Shape [PDF]
, 2014 We present a full pipeline for computing the medial axis transform of an arbitrary 2D shape. The instability of the medial axis transform is overcome by a pruning algorithm guided by a user-defined Hausdorff distance threshold.

Nonlinear Geometric Optics method based multi-scale numerical schemes for highly-oscillatory transport equations [PDF]
, 2016 We introduce a new numerical strategy to solve a class of oscillatory transport PDE models which is able to captureaccurately the solutions without numerically resolving the high frequency oscillations {\em in both space and time}.Such PDE models arise ...
