OBSTACLE DETECTOR FOR CONSTRUCTION VEHICLE
To provide an excellent obstacle detector for a construction vehicle which can reduce the frequency of false determinations of determining a cloud of dust or water vapor to be obstacles and can exhibit an excellent accuracy of detecting obstacles.SOLUTION: The present invention relates to an obstacle detector equipped in a construction vehicle, the obstacle detector including: a distance image sensor of a TOF system which can measure the coordinates of an obstacle from the time difference between projected light and reflected light; and a controller for determining the presence or absence of obstacles on the basis of coordinate data measured by the distance image sensor and the intensity of reflection of the reflected light. The controller does not determine the presence of obstacles when the intensity of reflection is not larger than the threshold value T.SELECTED DRAWING: Figure 10
【課題】水蒸気や砂埃等を障害物と誤判定することを低減でき、障害物の検知精度に優れた建設車両の障害物検知装置を提供する。【解決手段】建設車両に搭載される障害物検知装置であって、投射光と反射光との時間差から障害物の座標を測定可能なＴＯＦ方式の距離画像センサと、距離画像センサで測定された座標データと、反射光の反射強度とに基づいて障害物の有無を判定する制御装置と、を備える。制御装置は、反射強度が閾値Ｔ以下の場合には障害物と判定しない。【選択図】図１０
