VEHICLE WEIGHT MEASURING SYSTEM AND METHOD FOR VEHICLE PASSING ON BRIDGE, AND COMPUTER PROGRAM

PROBLEM TO BE SOLVED: To provide a vehicle weight measuring system for calculating a vehicle weight with high precision without having adverse effect upon a vehicle running speed. SOLUTION: A vehicle detection processing part 21 outputs detection vehicle image data 33 based on monitor image data 31 photographed by a camera 5 and entry data 32 measured by a strain gauge 9 for axle detection. An axle position identification processing part 23 traces the detection vehicle image data 33 from the monitor image data 31 at every determined time and performs position identification of a leading axis based on axis interval data. An interference line data conversion processing part 24 converts time axis influence line data 40 to time axis influence line data 35 based on the axis interval data. A vehicle weight calculation part 25 performs vehicle weight calculation processing based on axis weight calculation data 36 measured by the strain gauge 7 for axis weight calculation and the time axis influence line data 35, thereby to determine the weight of a vehicle 10.
