摘 要：Realism rendering methods of outdoor augmented reality(AR)is an interesting *** items in outdoor AR need advanced impacts like shadows,sunshine,and relations between unreal items.A few realistic rendering approaches were built to overcome this *** of these approaches are not dealt with real-time ***,the issue remains an active research topic,especially in outdoor *** paper introduces a new approach to accomplish reality real-time outdoor rendering by considering the relation between items in AR regarding shadows in any place during *** proposed method includes three principal stages that cover various outdoor AR rendering ***,real shadow recognition was generated considering the sun’s location and the intensity of the *** second step involves real shadow ***,we introduced a shadow production algorithm technique and shades through its impacts on unreal items in the *** selected approach’s target is providing a fast shadow recognition technique without affecting the system’s *** achieved an average accuracy of 95.1%and an area under the curve(AUC)of 92.5%.The outputs demonstrated that the proposed approach had enhanced the reality of outside AR *** results of the proposed method outperformed other state-of-the-art rendering shadow techniques’outcomes.
