  • Objective Geometric matching of electronic map data for navigation is one of the most common meth-ods used for road network object matching:threshold selection is the precondition for geometric matc-hing.Nowadays,there are many disadvantages in the existing methods,such as poor adaptability,1066 large errors,low precision.Aiming to solve these drawbacks,we took the advantage of multimodaldistribution characteristics in the matching data,and proposed a dynamic calculation method for matc-hing threshold based on the method of maximum classes square error(OSTU method).In this re-search,the fundamental principles and implementation process are introduced and detailed.Experi-mental results show that the proposed method has advantages of better self-adaptivity and higher accu-racy.Furthermore,the proposed method is easy to realize,and has potential to be widely used.
