A pavement three-dimension information detection device and method for roads are disclosed. The device includes a pavement information collecting system, a vehicle vibration correcting system, a pavement three-dimensional information integration system and a positioning system. The pavement three-dimensional information integration system is separately electrically connected to the pavement information collecting system, the vehicle vibration correcting system and the positioning system, and is used for integrating pavement images, vehicle gesture information, vehicle vibration information, vehicle travelling tracks and vehicle position information, and integrates deformation information of different fracture surfaces and different lanes to a same datum plane to determine pavement three-dimensional information. The pavement three-dimensional information includes the degree of rut damage, the degree of pot hole damage, the degree of subsidence damage, the degree of upheaval and wave damage and the degree of flatness. Through the detection device and the method, the degree of damage of a pavement can be accurately determined and image processing speeds and precision are increased.
Description
technical field [0001] The present invention relates to the field of road surface three-dimensional information detection, in particular to a road surface three-dimensional information detection device, method and system. Background technique [0002] Road roughness is used to reflect the impact of the road on the vehicle vibration and bumps due to longitudinal deformation and lateral deformation acting on the vehicle along the direction of the driving track. According to its detection principle, the detection equipment for road surface unevenness is mainly divided into two types, namely, the reaction type flatness meter and the section type flatness meter. Among them, the reaction-type roughness meter is directly used to detect the vehicle reaction, and can only obtain macroscopic statistical data related to the road roughness, not the deformation characteristics of the road surface itself. The cross-section flatness instrument includes two directions of the horizontal and...
