The present invention discloses a kind of verification system based on the nascent crackle acquisition system of line-structured light benchmark vehicle-mounted road surface, it is intended to overcome the problem that cannot realize the nascent crackle acquisition system calibrating of the vehicle-mounted road surface based on line-structured light benchmark. This system comprises lift in height adjustment platform (1), target plate (2) and wedge piece (3). This design provides the system that one can adjust platform (1) by lift in height and wedge piece (3) adjusts height and angle respectively and then the nascent crackle acquisition system of vehicle-mounted road surface based on line-structured light benchmark examined and determine.
Description
Technical field
The present invention relates to the calibration equipment of the test set in a kind of Vehicle Detection field, say more specifically, it relates to a kind of verification system based on the nascent crackle acquisition system of line-structured light benchmark vehicle-mounted road surface.
Background technology
Highway pavement crack detection is one of important research content of traffic engineering subject, its Research Significance is the path formation detection scheme seeking to ensure that road surface supporting capacity is optimum, vehicle movement ride comfort is best, road traffic accident is minimum, fuel oil consumption is minimum, safeguarding in advance for highway provides sufficient modern technique to ensure and theory support, reaches the object of road and people, vehicle harmony.
In the end of the year 2011, the motorway mileage that China is open to the traffic has reached 8.5 ten thousand kilometers. The Economic development of each department is served very important pushing effect by the fast growth of total mileage of highway, and the life-time service of highway also brings unprecedented challenge to highway maintenance simultaneously. On the one hand, traffic flow increase sharply, the problem road pavement such as high capacity waggon overload destroy day by day serious; On the other hand, the construction in the medium-and-large-sized engineering machinery of maintenance of surface process can cause blocking up for a long time of highway, seriously affects road ability. Therefore, under the severe background that the end of the year 2012, China's motor vehicle car recoverable amount reached 2.4 hundred million, modern technique theory is utilized to carry out periodic detection and quantitative evaluation with detection method road pavement crackle, make it be in zone of reasonableness and actively carry out the early stage maintenance on road surface, to extend the work-ing life of highway, the traffic capacity improving road, ensure automobile driving safety and the maintenance cost that reduces highway has important theory significance and application prospect widely.
At present, mainly stopping the detection of road crackle at manual measurement, efficiency is low, low precision, and intensity of workers is big. Adopting machine vision to gather pavement image and then the method that realizes crack detection evaluation solves above technical bottleneck, the verification system therefore studying the nascent crackle acquisition system of the vehicle-mounted road surface based on line-structured light benchmark is significant to the technical progress in Vehicle Detection field.
Summary of the invention
The present invention is directed to the present situation that cannot realize at present the nascent crackle acquisition system of vehicle-mounted road surface based on line-structured light benchmark is examined and determine, adopt the combination of lift in height adjustment platform, target plate and wedge piece provide a kind of cost compared with low, structure simple, accuracy of detection height, progressive error are little, function is complete, easy and simple to handle, be easy to installations, the road surface vehicle-mounted road surface based on line-structured light benchmark that flaw detection system requires of coming into being is come into being the verification system of crackle acquisition system in the met small field of view scope of highly versatile, dependable performance.
Consulting Fig. 1 to Fig. 2, for solving the problems of the technologies described above, the present invention adopts following technical scheme to be achieved.The verification system of the nascent crackle acquisition system of the vehicle-mounted road surface based on line-structured light benchmark provided by the present invention includes lift in height adjustment platform, target plate and wedge piece.
Wedge piece is placed on the upper surface of the horizontal countertop of lift in height adjustment platform, and target plate is placed on the upper surface of wedge piece and contacts with the upper surface face of wedge piece, and the edge of target plate coordinates with the end edge linear contact lay of wedge piece.
Target plate described in technical scheme is the rectangular parallelepiped part of steel plate processing, and chessboard grid pattern is pasted on target plate surface.
Wedge piece described in technical scheme is the wedge shape part of steel plate processing, and wedge piece has magnetic.
The invention has the beneficial effects as follows:
(1) the present invention adopts the angle of inclination of the angle of wedge metering target plate of the wedge piece of the fixed angle with magnetic to simulate the angle on road surface, adopt the height of lift in height adjustment platform adjustment target with the distance on simulated range camera distance ground, it is achieved that the nascent crackle acquisition system of vehicle-mounted road surface based on line-structured light benchmark is measured comprehensive calibrating of road surface crackle image.
(2) major part of the present invention adopts Standard Steel Section to process, and first, Standard Steel Section output is big, and mechanical workout operation is few, and production cost is lower; Secondly, as the important accessory of surveying instrument, adopt Standard Steel Section to have certain intensity, it is possible to not to be out of shape in life-time service, ensure the precision measured, it is possible to meet national standard to the requirement of measuring accuracy.
