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.
Claims12
A system for determining a kind of vehicle, comprising:
- 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.
A method for determining a kind of vehicle, comprising the steps of:
- counting a number of vehicles which travel on a roadway with an optical sensor;
- yielding the distance and width of tires of the vehicle on the basis of the photographed image;
- and
- determining the kind of vehicle by comparing the counted number of wheel shafts and the yielded distance and width values with a vehicle kind classification table.
