摘要
Abstract
Aiming at the efficient retrieval of road graphs in the running graph tasks,we proposed a road graph retrieval method.Taking the local shape features of graph as constraints,we performed a one-by-one search on each road segment in the road network to screen out a set of roads that matched the input shape,thus obtaining a candidate set of retrieval results at first.Then,we established similarity metrics,and sorted the candidate paths.Finally,we outputted the optimal retrieval result that best met the user's requirements.Experimental result proves that the proposed method successfully realizes the automation of road graph retrieval in running graph,providing users with a convenient and personalized running graph experience.关键词
