To provide a pedestrian detection device and a pedestrian detection method capable of detecting a pedestrian with high accuracy even when the pedestrian cannot be detected by using an identification dictionary.SOLUTION: The pedestrian detection device comprises a dictionary storage unit in which an identification dictionary is stored, an image storage unit in which an image of a pedestrian detected from a past image is stored as a template image in association with the pedestrian, a tracking unit configured to track the position of the detected pedestrian and predict a pedestrian position where the pedestrian is present in the current image, a first detection unit configured to detect the pedestrian by searching for a location having a feature of the identification dictionary in the current image, and a second detection unit configured to detect the pedestrian from a predetermined area of the current image by executing matching between the predetermined area and the template image, when the pedestrian is not detected by the first detection unit in the predetermined area including the predicted pedestrian position in the current image.SELECTED DRAWING: Figure 3

    【課題】識別辞書を用いて歩行者を検出できない場合でも、歩行者を高精度に検出可能な歩行者検出装置、及び歩行者検出方法を提供する。【解決手段】識別辞書が記憶されている辞書記憶部と、テンプレート画像として、過去画像から検出された歩行者の画像が歩行者と対応づけられて記憶されている画像記憶部と、検出された歩行者の位置を追跡して、現在画像において歩行者が存在する歩行者位置を予測するトラッキング部と、現在画像において、識別辞書の特徴を有する箇所を探索して、歩行者を検出する第1検出部と、現在画像における予測された歩行者位置を含む所定領域において、第1検出部によって歩行者が検出されなかった場合に、所定領域とテンプレート画像とのマッチングを実行して、現在画像の所定領域から歩行者を検出する第2検出部と、を備える。【選択図】図3
