PROBLEM TO BE SOLVED: To detect a pedestrian in a taken image with high detection accuracy.SOLUTION: A plurality of types of identification dictionaries is stored and pedestrian detection results for the respective identification dictionaries are stored. Furthermore, a pedestrian detection result by a sonar or a radar is also stored. One identification dictionary having highest matching to the detection result by the sonar or the radar is selected from among the plurality of types of identification dictionary, and a pedestrian in a taken image is detected using the selected identification dictionary. By doing so, even if an environmental factor changes, it is possible to select the most appropriate identification dictionary from among the plurality of types of identification dictionaries and detect the pedestrian in the taken image. It is, therefore, possible to detect the pedestrian with high detection accuracy.SELECTED DRAWING: Figure 2
【課題】撮影画像中の歩行者を高い検出精度で検出する。【解決手段】複数種類の識別辞書を記憶しておき、それぞれの識別辞書について歩行者の検出結果を蓄積する。また、ソナーまたはレーダーによる歩行者の検出結果も蓄積しておく。そして、複数種類の識別辞書の中から、ソナーまたはレーダーによる検出結果と、最も整合する識別辞書を選択して、選択した識別辞書を用いて撮影画像中の歩行者を検出する。こうすれば、環境要因が変化しても、複数種類の識別辞書から最も適した識別辞書を選択して、撮影画像中の歩行者を検出することができるので、歩行者を高い検出精度で検出することが可能となる。【選択図】図2
