Identification Method of Pavement Crack Based on Topology Contravariant

Abstract

This paper use the topology contravariant to discriminate the intrinsic properties of the pavement crack, structure the metric space of complex data set, make up the topology space, deduce the topology contravariant relation. To distinguish the pavement crack, the data of the crack must be gained. Using the topology contravariant relationship from the original space of the Pavement crack to the target space, the detection to the pavement is more accurate and faster. The theory of this paper has been tested by simulation.
