Precision vs. Accuracy Dilemma in Point-Based Rigid-Body Registration

Volume 12, Issue 1

Marek Franaszek, Geraldine Cheok

The purpose of a registration procedure is to determine the transformation between two coordinate frames: the working frame (from which 3D data are transformed) and the destination frame (to which the data are transformed). In point-based, rigid-body...

Photogrammetric Measurement of Cabin Bracket Riggings on the Airbus 350

Volume 12, Issue 1

Jean-Christophe Bry, Nabil Romman

The goal of this project was to obtain accurate 3D measurements of the many brackets that support the overhead luggage bins in the new Airbus 350 aircraft. The measured area was more than 21 m in length, and one of the key requirements was to perform the...

Freezing Time: Dynamic Laser Tracker Measurements With the Pixel Probe Using Temporal Aliasing

Volume 11, Issue 2

Joshua A. Gordon, Steven S. Borenstein

In this article, we present a noncontact technique for measuring objects in motion with a laser tracker without need of the laser tracker following the object. This method allows the dynamic state of an object to be measured while, to the laser tracker,...

Noncontact Measurement of Mirrors With a Laser Tracker

Volume 11, Issue 2

Chenghao Yu, Francis Karl, Matthew Ilardo, Ming Ke

A mirror in a static situation can be measured by a laser tracker with its reflector, based on the principle of reflection. Each surface location needs to be measured twice: once for the image point after reflection and again for the same point directly...

Using Perona-Malik Anisotropic Heat Diffusion for Data Reduction in Coordinate Metrology

Volume 11, Issue 2

Hossein Gohari, Ahmad Barari

The measurement uncertainty in coordinate metrology systems is greatly affected by the number and location of the sampled discrete points. Increasing the density of points provides more data from the measured surface, but it also increases computational...

Effects and Uncertainties Associated With Indirect Measurements of Points on Rigid Bodies

Volume 11, Issue 2

Robert Flynn, Carson Miller

A common item in the “metrology toolkit” is indirect, or inferred, measurement. Vector bars, hidden-point rods, T-Probes, and B-Probes are all examples of tools that use indirect measurements. The practice is to accurately measure all critical features...
