Abstract
From the perspective of Location Based Services, this paper explores basic characteristics, architectural design and application mode of outdoor Augmented Reality (AR) spatial information representation. Then system structure is proposed and key technologies are analysed. Finally, two cases are designed to verify the efficiency and accuracy of methods. One puts forward and practices a hybrid hardware registration method. In order to avoid complex and tedious process of position tracking and camera calibration, the other introduces algorithm of computer vision to set up global affine coordinate system for computing projection coordinates of virtual objects into real scene images, and an approach to get the relative depth of pixels is put forward. The results have proved outdoor AR spatial information representation to be an effective optimal method in helping people obtain a vivid and deep-level spatial cognition.
