To provide a technique for improving accuracy of vehicle detection.SOLUTION: A vehicle processing device (10) includes a light-emitting part (EU) and a light-receiving part (RU), and has a processing function of detecting a vehicle by light passage and light shielding based on a threshold (S) of a light-receiving quantity between the light-emitting part (EU) and the light-receiving part (RU). The light-receiving part (RU) has a plurality of light-receiving elements (R) aligned in a vertical direction. Before detecting a vehicle (C), calibration values (rc) are set in each of the plurality of light-receiving elements (R) from the light-receiving quantity according to presence/absence of light emission of the light-emitting part (EU), and the threshold (S) is set from the calibration values (rc) with reference to different ratios (h1 and h2) in a vertical direction.SELECTED DRAWING: Figure 5

    【課題】車両検出の精度を向上することのできる技術を提供する。【解決手段】車両処理装置(10)は、発光部(EU)および受光部(RU)を備え、発光部(EU)と受光部(RU)との間において受光量の閾値(S)を基準とした通光、遮光により車両を検出する処理機能を有する。ここで、受光部(RU)は、鉛直方向に沿って並んだ複数の受光素子(R)を有する。車両(C)を検出する前段階において、複数の受光素子(R)のそれぞれに発光部(EU)の発光の有無による受光量から校正値(rc)を設定し、鉛直方向で異なる比率(h1、h2)を参照して校正値(rc)から閾値(S)を設定する。【選択図】図5
