To recognize traffic light machines with high accuracy.SOLUTION: A traffic light machine recognition device has: a template image creation device that creates a plurality of reference images representing traffic light machines captured in an environment where the way light hits is different; a storage unit that stores the plurality of reference images; a capturing image acquisition unit that acquires a capturing image captured by an imaging unit; an extraction unit that extracts a light emission area from the capturing image; and a traffic light machine determination unit that, of the capturing image, compares the image of a candidate area of a traffic light machine to be identified based on the light emission area extracted by the extraction unit with the reference image, and determines whether the image of the candidate area is the image of the traffic light machine, in which the template image creation device has a template image creation unit that classifies sample images having the traffic light machine captured in various environments in accordance with a characteristic of the sample image, and creates one reference image from the sample image classified into the same group.SELECTED DRAWING: Figure 3

    【課題】信号機を精度良く認識する。【解決手段】光の当たり方が異なる環境で撮像された信号機を表す複数の基準画像を生成するテンプレート画像生成装置と、前記複数の基準画像を記憶する記憶部と、撮像部によって撮像された撮像画像を取得する撮像画像取得部と、前記撮像画像から発光領域を抽出する抽出部と、前記撮像画像のうち、前記抽出部によって抽出された発光領域に基づいて特定される信号機の候補領域の画像と、前記基準画像とを比較して、前記候補領域の画像が信号機の画像であるか否かを判定する信号機判定部と、を有する信号機認識装置において、前記テンプレート画像生成装置は、様々な環境において信号機を撮像したサンプル画像を、前記サンプル画像の特徴に応じて分類し、同一のグループに分類された前記サンプル画像から、1つの前記基準画像を生成するテンプレート画像生成部を有する。【選択図】図3
