Matching Road Network Based on the Structural Relationship Constraint of Hierarchical Strokes

From the visual attention mechanism when people are looking for the sameroad, this paper proposed a road network matching method based on hierarchical stable strokes. The method adopts the principle of matching from obvious to vital, and constructs larger matching unit “stroke” instead of “road section”. First, the correspondence of strokes is calculated; Then, the detailed node correspondence is further identified. The results show that: when calculating similarity, the differences rate between candidate strokes and the largest reference solution is more significant than that of road segment. In this example,10 percent of the first layer strokes can ensure the stability of the matching relationship. Layered stable reference and hierarchical strokes improves the ability to identify matching relation, and it has obvious advantages in the region with similar local structure and obviously different global strokes.
