ACTIVE AND PASSIVE 3D IMAGING TECHNOLOGIES APPLIED TO WATERLOGGED WOODEN ARTIFACTS FROM SHIPWRECKS
3D modelling data processing waterlogged artefacts restoration laser scanning image-based modelling photogrammetry
2015/4/23
The fragility of organic artefacts in presence of water and their volumetric variation caused by the marine life on or surrounding them dictate that their physical dimensions be measured soon after th...
A contest of sensors in close range 3D imaging: performance evaluation with a new metric test object
3D imaging museum documentation close range laser scanning cultural heritage comparison inspection
2014/7/30
An independent means of 3D image quality assessment is introduced, addressing non-professional users of sensors and freeware, which is largely characterized as closed-sourced and by the absence of qua...
3D painting documentation: evaluation of conservation conditions with 3D imaging and ranging techniques
Cultural Heritage Photogrammetry Structured light sensor Monitoring, Comparison
2014/7/30
The monitoring of paintings, both on canvas and wooden support, is a crucial issue for the preservation and conservation of this kind of artworks. Many environmental factors (e.g. humidity, temperatur...
3D IMAGING FOR MUSEUM ARTEFACTS: A PORTABLE TEST OBJECT FOR HERITAGE AND MUSEUM DOCUMENTATION OF SMALL OBJECTS
3D imaging museum documentation close range laser scanning cultural heritage comparison inspection
2014/4/28
3D colour image data generated for the recording of small museum objects and archaeological finds are highly variable in quality and fitness for purpose. Whilst current technology is capable of extrem...
3D Imaging of a Phase Object from a Single Sample Orientation Using an Optical Laser
3D Imaging Single Sample Orientation Optical Laser
2011/8/4
Abstract: We acquire coherent diffraction patterns of a microscale phase object at a single sample orientation by using an optical laser. The diffraction patterns are projected onto a spherical shell ...

2010/3/8
Objective: To compare the facial morphologies of an adult Egyptian population with those of a Houstonian white population.
Materials and Methods: The three-dimensional (3D) images were acquired via a...
A crash avoidance framework for heavy equipment control systems using 3D imaging sensors
crash avoidance path planning spatial modeling object tracking
2010/9/28
This paper presents a preliminary crash avoidance framework for heavy equipment control systems. Safe equipment operation is a major concern on construction sites since fatal on-site injuries are an i...
