Title (EN) OBJECT DETECTOR
(FR) DÉTECTEUR D’OBJETS
(JA) 物体検出装置
Abstract:
(EN) An object position area (82a) is calculated according to a position in the space of a detected truck (70). A template (80a) corresponding to the object position area (82a) recorded at the previous time is then called. The template (80a) is moved to a position on a reference image Ib where the similarity is highest. Overlap rate (R(t-1)⊥Rt) of the object position area (82a) and the template (80a) is calculated. A decision is made whether the object is identical to that detected in the past by using the overlap rate.
(FR) La zone de position d’objets (82a) de l’invention est calculée selon une position dans l’espace d’un camion détecté (70). Un modèle (80a) correspondant à la zone de position d’objets (82a) enregistrée au préalable est alors rappelé. Le modèle (80a) est déplacé vers une position sur une image de référence Ib où la similarité est à son comble. Le taux de chevauchement (R(t-1)⊥Rt) de la zone de position d’objets (82a) et du modèle (80a) est calculé. Une décision est prise pour savoir si l’objet est identique à celui détecté au préalable en utilisant le taux de chevauchement.
(JA)  検出されたトラック70の空間上での位置に基づいて物体位置領域82aを算出する。前時刻に記録された物体位置領域82aに相当するテンプレート80aを呼び出す。テンプレート80aを基準画像Ib上で類似度が最大となる位置に移動させる。物体位置領域82aと移動したテンプレート80aとの重なり割合(R(t-1)∩Rt)を算出する。重なり割合を用いて、過去に検出された物体と同一か否かを判断する。
