A Vision-aided Localization and Geo-registration Method for Urban ARGIS Based on 2D Maps
文献摘要：
Augmented Reality Geographic Information System(ARGIS)applications can only provide users accurate content services with a highly precise geo-registration.However,the absolute 6DOF(Degree of Freedom)pose provided by the portable sensors is usually inaccurate in urban outdoors,resulting in poorly geo-registration accuracy for ARGIS applications.Aiming at this issue,an automatic vision-aided localization method based on the 2D map is proposed to improve the initial localization accuracy of the portable sensors,and an overall geo-registration optimization framework for outdoor ARGIS is proposed.Based on the initial pose provided by the sensors,the basic principles of the vision-aided localization method are expounded in detail.The experimental results show that the proposed method can effectively correct the initial pose obtained by the pose sensors,and improve the geo-registration accuracy of outdoor ARGIS applications ultimately.
