Registration Strategy for Mobile Augmented Reality Based on Cone-View Partition Under the Restricted Visibility Environment

It is more popular to develop the navigation applications using mobile augmented reality (AR) with virtual-real fusion in near-earth view. Limited by the complex outdoor environments, such as the restricted visibility, the computing and storage capability of mobile devices, the target cannot be identified correctly under the conditions of perspective, narrow and close view angle. Furthermore, the virtual-real fusion display will be affected by the far distance and large camera angle. In this paper, the acquirement strategy for registration viewpoints based on image template is first analyzed, and then a registration strategy of mobile AR based on cone-view partition of outdoor building environments is proposed under the restricted conditions of occlusion and visibility. Finally, this strategy is successfully applied to the development kit of mobile AR and the experimental results demonstrate feasible for the typical buildings in campus.
