PROBLEM TO BE SOLVED: To provide a width measurement system with which it is possible to obtain information for determining whether or not a traveling vehicle has its laden cargo protruding from a side.SOLUTION: Each of distance sensors 81, 81scans a laser beam and measures the distance to a reflection point of the laser beam. Image data generation means 82 generates image data for each distance sensor on the basis of the data outputted by the distance sensors. Wheel portion detection means 83 detects the wheel portion of a vehicle from within the image. First width calculation means 85 calculates the vehicle width of the vehicle on the basis of the horizontal distance from each distance sensor to the wheel portion. Second width calculation means 87 calculates the maximum width of the vehicle on the basis of the minimum value of horizontal distance from each distance sensor to the reflection point.SELECTED DRAWING: Figure 12

    【課題】走行中の車両が積載物が側面からはみ出した状態の車両であるか否かを判定するための情報を得ることができる幅計測システムを提供する。【解決手段】距離センサ81a,81bはそれぞれ、レーザ光をスキャンし、レーザ光の反射点までの距離を計測する。画像データ生成手段82は、距離センサ毎に、距離センサが出力したデータに基づいて画像データを生成する。車輪部分検出手段83は、画像内から車両の車輪部分を検出する。第1の幅算出手段85は、各距離センサから車輪部分までの水平距離に基づいて、車両の車幅を算出する。第2の幅算出手段87は、各距離センサから反射点までの水平距離の最小値に基づいて、車両の最大幅を算出する。【選択図】図12
