3DUNDERWORLD-SLS v4 has been released.

The latest version features multiple optimizations in the processing pipeline. 3DUNDERWORLD-SLS v4.x requires two or more cameras and includes a CUDA GPU implementation as well as a CPU implementation in case an Nvidia card is not found. In this version, we provide a generic camera interface implementation and which the programmer can extend to support any kind of camera.

The source code and sample data can be found at the lab’s Github account.

The technical report can be found arxiv.

The latest stable version includes minor fixes and exports the models using the PLY-variant format used by 3DGSS. Using our output as the input to 3DGSS the models are automatically aligned and merged. The software can be downloaded from here: http://www.3dunderworld.org/software/

3DGSS is a command-line tool for automatic alignment and merging of range images. More information can be found here: cs.drexel.edu/~kon/3DGSS/

K. Herakleous, C. Poullis. “3DUNDERWORLD-SLS: An Open-Source Structured-Light Scanning System for Rapid Geometry Acquisition”, ICT-TR-2014-01

Abstract: Recently, there has been an increase in the demand of virtual 3D objects representing real-life objects. A plethora of methods and systems have already been proposed for the acquisition of the geometry of real-life objects ranging from those which employ active sensor technology, passive sensor technology or a combination of various techniques.

In this paper we present the development of a 3D scanning system which is based on the principle of structured-light, without having particular requirements for specialized equipment. We discuss the intrinsic details and inherent difficulties of structured-light scanning techniques and present our solutions. Finally, we introduce our open-source scanning system “3DUNDERWORLD-SLS”  which implements the proposed techniques. We have performed extensive testing with a wide range of models and report the results. Furthermore, we present a comprehensive evaluation of the
system and a comparison with a high-end commercial 3D scanner.

The ICT lab visited the new multipurpose centre, CUTing Edge, to set up and test their new 3D printer. The centre’s supervisor, Dimitrios Boglou and Francesca Sella (ICT lab’s alumni) showed us the place and their cutting edge equipment.

In order to test the 3D printer, models scanned with our open-source software 3DUNDERWORLD-SLS were used. Check out the following video, to see the scanning procedure as well as the printing of Alexander’s model.

Two new high-fidelity reconstructed 3D models have been published through our website’s download section. The models were produced with the in-house developed reconstruction software 3DUNDERWORLD-SLS v.3.0 and v.3.1 respectively, which is also publicly available for non-commercial use.

Following up on the many requests to make some test data available for the dual camera setup, we make available in the Downloads page: the Alexander data. The data consists of the images taken by two cameras for one scan. This is the actual data used to generate the Alexander model. The camera calibration information is also included.
