Talk: The 13th International Conference on Advances in Mobile Computing and Multimedia (MoMM 2015), Brussels, Belgium; 2015-12-11 - 2015-12-13; in: "The 13th International Conference on Advances in Mobile Computing and Multimedia", ACM, (2015), ISBN: 978-1-4503-3493-8; 334 - 337.

In this work we investigate an infrared structured light prototype which is intended for 3D reconstruction in resource-restricted mobile applications. We explore the constraints on working range and pattern resolution that are imposed by the low-light property of our single-shot set-up. While focusing on the most light-sensitive steps of the decoding work ow, we suggest adaptations of image rectification and pattern generation and segmentation algorithms that are tailored to the specific spatial and radiometric requirements of our system.
