  • Patent number: 6965438
    Abstract: Vehicle measuring apparatus and method are disclosed to accurately measure height and width of a vehicle moving at a high speed. The vehicle measuring apparatus includes: a plurality of laser sensors separated from the road surface with a predetermined height and installed closely to each other corresponding to width of every roadway on the road, and receiving a reflection light of a laser light emitted onto the road from the plurality of the laser sensors and outputting a vehicle measurement signal; and a processor means electrically connected to the laser sensors and calculating height and width of the vehicle on the basis of the signal to measure the vehicle and previously stored installation information of the plurality of laser sensors.
    Type: Grant

    Date of Patent: November 15, 2005
    Assignee: LG Industrial Systems Co., Ltd.
    Inventors: Sang-Jean Lee, In-June Song, Dae-Woon Lim, Joon-Suk Jun
  • Patent number: 6897789
    Abstract: A system for determining a kind of vehicle and a method therefore, including a vehicle detection unit for detecting a vehicle which reaches to a vehicle detection region on a roadway, a wheel shaft number counting unit for counting a number of wheel shafts of the detected vehicle, an image photographing unit for photographing a front or rear image of the detected vehicle and a vehicle kind determination unit for yielding distances and widths of the tires of the detected vehicle on the basis of the photographed image from the image photographing unit and determining the kind of the vehicle on the basis of the number of wheel shafts detected from the wheel shaft counting unit and the yielded distance and width values can precisely determine the kind of vehicle traveling the roadway.
