Assessment Of The Impact Of Clothing And Environmental Conditions On Visible Light 3d Scanning, Pann Ajjimaporn, Jeremy Straub, Scott Kerlin

Jeremy Straub

The quality of models produced by visible light 3D scanners is influenced by multiple factors. To max-imize model accuracy and detail levels, the correct combination of lighting texture, subject posture and software usage must be selected. The work described herein has been performed to measure the effect of different lighting and envi-ronmental conditions on human 3D scanning results.

A Web-Based Job Management System For Three-Dimensional Printing And Scanning At The University Of North Dakota, Dalyn Limesand, Stephanie Hollman, Jeremy Straub, Scott Kerlin

Jeremy Straub

Three-dimensional (3D) printers have gained popularity for use for many different projects. The work presented herein aims to make this process simpler. This paper discusses a system that will allow individuals from across campus to submit object files for printing by a 3D printer, without having to schedule appointment and manually operate it.

Logistical requirements dictate some level of human involvement, despite a goal of creating a fully automated system. Involvement areas include converting /preparing submitted files, sending the job to the printer, print tray preparation, and completed object removal. From a user’s perspective, however a seamless experience is anticipated. …

Development Of A Low-Cost Portable 3d Scanner Using Visible Light Cameras, Brendan Ydstie, Tierra Novacek, Benjamin Kading, Jeremy Straub, Scott Kerlin

Jeremy Straub

The medical field is beginning to use advanced manufacturing technologies such as three-dimensional (3D) scanning (where a real-world object is turned into a digital model) and printing (where a digital model is turned into a real-world object) to create customized prosthetics and other medical devices to address the specific needs of patients. This technology provides an efficient way to customize prosthetics to fit a particular person and his or her unique shape, making the prosthetics easier for the patient to use and in some cases, meeting needs that cannot be met via pre-fabricated equipment. The use of 3D scanning facilitates …

Using A Constellation Of Cubesats For In-Space Optical 3d Scanning, Jeremy Straub

Jeremy Straub

The assessment of in-space objects is an area of ongoing research. Characterization of resident space objects (RSOs) can be useful for assessing the operating status of operator-affiliated or non-affiliated space assets, identifying unknown objects or gathering additional details for known objects. Under the proposed approach, a ring-like constellation of CubeSats passes around the target (at a distance) collecting imagery. This imagery is then utilized to create a 3D model of the target. This paper considers several key elements of a constellation to perform this type of imaging, including the constellation design and imaging capabilities required and the astrodynamics relevant to …
