PROBLEM TO BE SOLVED: To provide a reflection target detection method for suppressing the erroneous detection of a reflection target caused by the sudden time axis fluctuation of a pixel value and to provide a reflection target detection device.SOLUTION: In the reflection target detection method, reflection light synchronized with the periodical change of the intensity of light projected by a projector is extracted from a camera image acquired by a camera mounted on a vehicle, the existence region of the reflection target on an image is estimated on the basis of the luminance of the reflection light, and it is discriminated whether or not the reflection target is obtained, to detect the reflection target on the basis of the periodical change of the luminance on the space axis of the image in the existence region of the reflection target on the image.SELECTED DRAWING: Figure 9
【課題】急激な画素値の時間軸変動による反射物標の誤検出を抑制する反射物標検出方法及び反射物標検出装置を提供する。【解決手段】反射物標検出方法は、車両に搭載されたカメラが取得したカメラ画像から投光器が投光する光の強度の周期的変化と同期する反射光を抽出する。反射光の輝度に基づいて、画像上の反射物標の存在領域を推定する。そして、画像上の反射物標の存在領域内における画像の空間軸上の前記した輝度の周期的変化に基づいて、反射物標か否かを判別して、反射物標を検出する。【選択図】図9
