ReconstructMe – Towards a Full Autonomous Bust Generator Christoph KOPF*, Christoph HEINDL, Martin ANKERL, Harald BAUER, Andreas PICHLER Profactor GmbH, Steyr (Upper Austria), Austria http://dx.doi.org/10.15221/14.184 Abstract In the most recent years, 3D data acquisition was revolutionized by consumer grade real-time capable 3D depth cameras with appropriate data quality. A wide range of different 3D applications was developed since the release of these cameras. Especially the area of 3D body scanning became cost efficiently and the number of applications started to grow. A new trend is to generate 3D self-portraits and print them on commercial available 3D printer. This paper introduces a low-cost scanning system to generate printable 3D upper torso busts at home using commodity computation hardware. The workflow of the system is optimized to work without the need of any manual interaction with the user and any additional persons. It’s designed to generate 3D printable busts automatically which allows people without 3D knowledge to create their own 3D busts. The user just has to perform a full rotation (360 degrees) to capture the upper torso data from all views. The end of the full rotation is detected automatically. When the scanning procedure is done, a post processing routine is triggered. This routine includes cleaning the scan from noise, estimating the geometry and color of unseen areas and cutting the bust to a certain height. The final result is a watertight, scaled and oriented triangle mesh. This allows the user to put the final mesh to common 3D printer drivers and immediately print its 3D bust. In our tests, the workflow was proven to be very robust and we were able to generate hundreds of 3D busts with high recognition value of the persons. However, our tests showed different results depending on the conditions. In this paper we will introduce our experience of how the setup can be improved and thus the quality of the results can be enhanced. In future, this principle could be extended by using more than one sensor at the same time to capture the whole body shape of a person and to generate clean 3D full body models.

However, industry already recognized the potential of 3D before, but for mass production, it was still too expensive. Object recognition, tracking, scanning of objects are common tasks in the 3D world, which now can enter homes. As 3D printers are getting cheaper, the number of 3D online printing services starts to grow and the low-cost sensors fill the market. This also means, that 3D is getting more popular and it’s up to technicians and visionaries to bring these 3D devices together and enable powerful applications. However, creativity is an important factor to motivate people to use new technology. Thus, intuitive and creative applications are required to make people familiar with 3D. Many creative applications are about scanning full body shapes and use them for tasks people are familiar with. Common usage examples can be found in apparel, medicine, sports industry or simply to make a physical 3D model of themselves. In our case, we have developed an application that is able to generate 3D busts of persons entirely on their own. Only common computer hardware and a 3D sensor are required. Due to the intuitive process design, home users without any knowledge of 3D technologies are now able to generate their own 3D busts. No additional persons and no post processing is required. The next chapters will introduce our system. 2. Related Work The release of 3D low-cost sensors made capturing objects in 3D affordable and thus, many people started to get interested in this technology. Since then, the number of 3D applications has been growing, especially when it comes to applications connected to human body scanning. * christoph.kopf@profactor.at; www.profactor.com 5th International Conference on 3D Body Scanning Technologies, Lugano, Switzerland, 21-22 October 2014 - 184 -
