Mobile Apps for 3D Face Scanning

Abstract

3D scanning is a rapidly growing field, and face scanning is a branch showing a great potential in various applications, but it is still new and little researched. As smartphone availability and functionality grows, the potential for 3D face scanning mobile apps has massively increased as well. Our study is aimed at finding and testing mobile apps that are suitable for 3D face scanning purposes. In our research we scanned two people’s faces using iOS and Android based smartphones. 6 mobile apps were found to be eligible: Bellus 3D, Heges, Scandy Pro, Capture, Trnio, 3D scanner Pro. 3D Scanner Pro were the only Android based app that was found to be suitable for face scanning purposes. Our research shows that based on visual evaluation, the most accurate face 3D models were made by Scandy pro, while Heges was better priced with similar accuracy. In the top three is also Bellus3D, which doesn’t provide the best resemblance to the scanning objects, but it was the easiest to use and process. Our quantitative measurements comparing face proportions show that the best accuracy for male face is obtained by Scandy pro and 3D Scanner Pro, but for female face – Scandy Pro and Capture.
