1. a road vehicles scanning type intelligent detection method, is characterized in that testing process completes in road vehicles scanning type intelligent pick-up unit, specifically comprises following processing step:

  • (1) entreat in the road by steel frame construction in opposite directions correspondence set up infrared laser array and infrared remote receiver array to form infrared laser raster, at vehicle by realizing the scanning to vehicle during infrared laser raster, Intelligent Measurement terminal is by periodically reading data with the scanning information of the vehicle passed to infrared remote receiver;

    (2) do not have vehicle through infrared laser raster, infrared remote receiver array is not in the light, and can effectively receive the useful signal of infrared laser array and form continuous print sweep trace;

    Have vehicle through infrared laser raster, infrared remote receiver array is in the light by vehicle, can partly receive the useful signal of infrared laser array and form interrupted sweep trace;

    (3) complete by the process of infrared laser raster at vehicle, infrared remote receiver array is in the light continuously by vehicle, thus forming the interruption sweep trace corresponding with vehicle '"'"' s contour, the interruption number of scanning lines of Intelligent Measurement terminal periodic reading infrared remote receiver array forms the face profile figure of vehicle according to this;

    (4) in Intelligent Measurement terminal, first real-time data acquisition is carried out to infrared laser raster, obtain the flat scanning figure that on road, vehicle travels, then apply active contour model and Image Edge-Detection and vehicle '"'"' s contour line drawing are carried out to the flat scanning figure that vehicle travels, and by detecting counting to vehicle wheel profile, realize the Intelligent Measurement of road traffic vehicle flowrate and car shape.
