Embodiment Construction

[0033] The technical solution of the present invention will be further described below in conjunction with specific embodiments:

[0034] A method for detecting pavement damage based on a joint detector, comprising the following steps:

[0035] Step 1: The road marking information in the road image can be removed by performing grayscale constraints on the collected road image. For any pixel point I(i,j) in the road image, there are:

[0036] I ′ ( i , j ) = μ I ( i , j ) > μ I ...

Abstract

The present invention discloses a method for detecting pavement damage based on a joint detector. The method comprises the following steps of: 1) eliminating marking information of a pavement image by using gray constraint; 2) eliminating a shadow region of the pavement image by using a brightness elevation model; 3) performing preprocessing on the pavement image by using a wavelet thresholding method to eliminate noise in the pavement image; 4) constructing a pavement damage joint detector by using a neighborhood gray difference method, a local gray minimum analysis method and a block marking method, and performing damage detection on the preprocessed pavement image. and 5) locating a damaged region of the pavement image by using a target connected domain. The method for detecting pavement damage based on the joint detector, disclosed by the present invention, is used for improving the efficiency of pavement damage detection, and provides an efficient and intelligent management basis for road management work, particularly pavement maintenance.

Description

technical field [0001] The invention relates to the field of intelligent traffic research, in particular to a road surface damage detection method for road management departments to carry out road surface maintenance management. Background technique [0002] The increase in traffic volume, large-scale vehicles, serious overloading and other phenomena lead to the appearance of road surface damage, which seriously affects the safety and comfort of road traffic. Pavement maintenance is the focus of highway maintenance, and pavement damage status plays an important role in pavement maintenance decision-making as the basis of pavement maintenance management. The types of pavement images include transverse cracks, longitudinal cracks, network cracks and normal types. The traditional pavement damage detection method uses manual detection, but this method has low work efficiency, high labor intensity, high degree of operation risk, and is affected by weather conditions, etc. The im...
