PROBLEM TO BE SOLVED: To provide a moving body detection system and data consistency determination method that can prevent wrong operations due to recognition of two or more moving bodies as a single body at a low load and at a low cost.SOLUTION: A moving body detection system comprises: imaging means (11) picking up an image in a traveling direction of an own vehicle; image processing means (12) for extracting moving bodies from the image, and outputting a location, width and speed of each moving body; and means (21) for predicting a future location of each moving body on the basis of the location, width and speed of each moving body. The moving body detection system comprises data consistency determination means (22) that includes: storage means (20) storing time-sequentially the location and width of each moving body; and first comparison and determination means comparing the width in a current frame of each moving body with the width in previous one or more frames stored in the storage means, and determining that the moving body is formed of a plurality of moving bodies when a change in the width is equal to or greater than a threshold.SELECTED DRAWING: Figure 1

    【課題】 2以上の移動体を単独と認識することによる誤作動を低負荷かつ低コストにて防止できる移動体検知システムおよびデータ整合性判定方法を提供する。【解決手段】 自車両の進行方向の画像を撮像する撮像手段(11)と、前記画像から移動体を抽出し、各移動体の位置、幅、速度を出力する画像処理手段(12)と、前記各移動体の位置、幅、速度に基づいて前記各移動体の未来位置を予測する手段(21)とを備えた移動体検知システムにおいて、前記各移動体の位置と幅を時系列で記憶する記憶手段(20)と、前記各移動体の現在フレームにおける幅を、前記記憶手段に記憶された直前の1ないし複数フレームにおける幅と比較し、幅の変化が閾値以上であれば、当該移動体が複数の移動体からなると判定する第1の比較判定手段とを含むデータ整合性判定手段(22)を備えた。【選択図】 図1
