To provide a road surface sign recognition method and a road surface sign recognition device which can accurately recognize a road surface sign.SOLUTION: A road surface sign recognition device 1 comprises: a camera 10 which images the periphery of the own vehicle at different timing plural times; and a controller 20 which processes the plurality of images captured at the different timing by the camera 10. The controller 20 calculates an optical flow using the plurality of images, selects, when the calculated optical flow is long, many images from the plurality of images in comparison to a case where the optical flow is short, selects a pixel having luminance equal to or greater than a prescribed level from the selected images, generates one composite image by using the selected pixel, and recognizes a road surface sign by using the generated composite image.SELECTED DRAWING: Figure 1

    【課題】路面標示を精度よく認識することが可能な路面標示認識方法及び路面標示認識装置を提供する。【解決手段】路面標示認識装置1は自車両の周囲を異なるタイミングで複数回撮像するカメラ10と、カメラ10によって異なるタイミングで撮像された複数の画像を処理するコントローラ20とを備える。コントローラ20は、複数の画像を用いてオプティカルフローを算出し、算出されたオプティカルフローが長い場合、短い場合と比較して多くの画像を複数の画像の中から選択し、選択された画像の中から所定以上の輝度を有する画素を選択し、選択された画素を用いて1枚の合成画像を生成し、生成された合成画像を用いて路面標示を認識する。【選択図】図1
