Poster: 3DBuilder - A Versatile Scheme to Reconstruct 3D Models on Smartphones

Abstract

There are bright prospects for 3D reconstruction on smartphones, such as 3D video, virtual reality, E-commerce and historic preservation. Although advent smartphones are equipped with high resolution touchscreens, powerful CPUs and GPUs, the performance of these smartphones is not comparable to desktop computers, especially in processing time and power consumption. Therefore, how to reconstruct 3D models on smartphones to increase its entertainment and functionality is an attractive challenge. In this work, we propose 3DBuilder, a versatile scheme to reconstruct 3D models on smartphones. It includes two parts to collaboratively render 3D models. On the client side, we provide an app running on Android smartphones to achieve image collection, keyframes uploading, 3D models downloading, rendering and displaying. On the cloud server side, cloud servers choose one algorithm from two different algorithms to reconstruct 3D models in non-real time or real-time. We use TCP/IP protocol to connect the client side and cloud server side to send images and models through Cellular network or Wi-Fi. Compared to previous work [1][2][3], 3DBuilder makes full use of mobile cloud computing to assist smartphones in 3D reconstruction. It provides various ways to make 3D reconstruction more useful in many scenarios.
