Bituminous pavement damage integrated intelligent detection vehicle

Abstract

The invention discloses a bituminous pavement damage integrated intelligent detection vehicle comprising a vehicle body, a pavement damage detector, a pavement deformation detector, a GPS apparatus, and a mileage range-measuring apparatus. The pavement damage detector is arranged on the front end of the vehicle body. The pavement damage detector is used for acquiring pavement damage information by taking pavement images. The pavement deformation detector is arranged on the rear end of the vehicle body. The pavement deformation detector determines pavement deformation information according to the deformation of two laser beams forming a crossed pattern projected onto the ground. The GPS apparatus is arranged on the top of the vehicle body. The mileage range-measuring apparatus is arranged on a wheel axle of the detection vehicle. According to the invention, continuous or intermittent shooting is carried out upon the pavement day and night. Also, with a structured light projection principle, the pavement 3-dimensional deformation is detected, and the interference of sunlight in day time is effectively overcome. Pavement damage areas are located, and accurate peg positions of the pavement damages relative to a route are obtained. With a normal running speed, damage and deformation data of a bituminous pavement can be obtained simultaneously.

Description

technical field [0001] The invention belongs to the field of traffic engineering and relates to a road surface detection vehicle, in particular to a detection vehicle aimed at the damage of asphalt pavement. Background technique [0002] With the substantial increase in the mileage of high-grade highways and expressways and the increase in traffic volume year by year, accurate and rapid detection of road damage without disturbing traffic has become an urgent need for road maintenance management. The main damage of asphalt pavement can be divided into surface damage and deformation. The scope and degree of these two types of damage are usually the basis for asphalt pavement maintenance. The pavement testing equipment that has come out or is in the research stage also mainly detects these two types of damage . Among them, non-destructive testing based on image processing technology is an important direction of research in this field, but the current technical level is still n...

AI Technical Summary

Problems solved by technology

At present, most laser structured light has the problem that it can only be detected at night or the detection accuracy is not high due to vibration.

In addition, no matter which technology is used, the current detection of road deformation has the problem of ignoring the three-dimensional deformation of the road surface, and the established three-dimensional shape of the road surface cannot accurately reflect the working state of the road surface.

At present, the integrated road surface detection equipment also has the following problems to varying degrees: the damage location technology only uses GPS or only uses the mileage controller, which has the disadvantages of inaccurate GPS positioning and ignoring the overall situation of mileage control; the detection device and the vehicle body are not integrated. Design, it is difficult to ignore the impact of the vibration of the vehicle body or detection device on the detection results during driving

[0004] In view of the above reasons, although a variety of automatic pavement detection equipment based on image processing has come out, its application in actual production practice is still very limited, and there is still a lot of room for research in this field.
