Research on Paper Map Augmented Reality Registration Technology

Paper map plays an irreplaceable role in geographical environment cognition. Through the transformation of augmented reality AR technique it will make a qualitative leap in three-dimensional expression dynamic vi-sualization and human-computer interaction. Theoretically the research focuses of the paper map AR is discussed and a feasible AR process is designed in this paper. Besides combined with the features of paper map graphics the paper map AR registration technology based on video processing is studied and a method for identifying infor-mation adaptively through map marker s database is proposed as well. In addition the key issues of the paper map AR registration technology are elaborated. Practically a prototype system of paper map AR is designed and con-structed based on the theory in this paper.
