Claims (5)

対象物体を構成する一または複数の部位の画像特徴である部位特徴を用いて、検出対象画像に対象物体像が存在するか否かを識別する物体検出装置であって、
前記検出対象画像における複数の位置に所定サイズの部位窓を設定し、当該部位窓内に対して前記部位特徴に適合する程度である部位適合度を算出する部位適合度算出部と、
前記部位適合度の分布を生成する分布生成部と、
前記部位適合度の分布を特徴量として前記対象物体の存否を識別する分布識別部と、
を少なくとも含むことを特徴とした物体検出装置。 An object detection device for identifying whether or not a target object image exists in a detection target image using a part feature that is an image feature of one or more parts constituting the target object,
A site suitability calculator that sets site windows of a predetermined size at a plurality of positions in the detection target image, and calculates a site suitability that is a degree that fits the site features within the site window;
A distribution generator for generating a distribution of the site suitability,
A distribution identifying unit that identifies the presence or absence of the target object using the distribution of the site suitability as a feature amount;
An object detection apparatus characterized by including at least. 前記部位適合度算出部は、部位ごとに前記部位窓を設定する探索範囲を定めた請求項１に記載の物体検出装置。   The object detection apparatus according to claim 1, wherein the part suitability calculation unit defines a search range in which the part window is set for each part. 前記部位適合度算出部は、前記部位窓のサイズを予め定めた変化量の範囲にて変化させる請求項１または請求項２に記載の物体検出装置。   The object detection apparatus according to claim 1, wherein the part suitability calculation unit changes the size of the part window within a predetermined change amount range. 前記分布生成部は、部位窓ごとに設定された前記検出対象画像における各部位の所在する基準位置から同一の投票位置までの投票ベクトルを用いて、部位適合度を算出した部位窓の位置から投票して前記部位適合度の分布を生成する請求項１〜請求項３の何れか１項に記載の物体検出装置。 The distribution generator uses a voting vector from a reference position where each part is located in the detection target image set for each part window to the same voting position, to vote from the position of the part window from which the part suitability is calculated. The object detection apparatus according to any one of claims 1 to 3, wherein the distribution of the site suitability is generated. 前記分布生成部は、前記検出対象画像を複数領域に分割し、当該分割領域ごとに前記部位適合度の分布を生成する請求項１〜請求項４の何れか１項に記載の物体検出装置。 The distribution generation unit, the detection target image is divided into a plurality of regions of the object detection apparatus according to any one of claims 1 to 4 to produce a distribution of the site fit for each the divided regions.
