Network Assistance to Localization and Mapping for Outdoor Augmented Reality in Cellular Network

A mobile device performs localization and mapping processes for an augmented reality (AR) application. In an outdoor envi-ronment, the mobile device requires more computing power to compute a camera's location and pose in real-time, to construct a 3D point cloud, and to render virtual images. However, the resources (e.g., processor, memory) of the mobile device are limited. With advances in cloud computing and 4G wireless network technologies that provide a 100 Mbits/s transmission rate with guaranteeing the latency of 40 ms, network assistanc-es can be considered to avoid complex computations at the mobile device. In this paper, network-assisted methods to the localization and mapping processes are introduced in a cellular network environment.
