To provide an information processor capable of reducing influence of a detected position error caused by a position estimation error factor on a road surface.SOLUTION: An information processor acquires an image, detects, on the basis of the image, an object position on the image, and converts the object position on the image to an object position in world coordinates; in moving object tracking (prediction unit) 34, a reliability calculation unit 710 calculates reliability of the object position in the world coordinates; an error factor existence determination unit 711 determines whether the detected object position on the image is affected by a position estimation error factor on a road surface; a reliability change unit 712 changes the reliability of the object position according to a determination result of the error factor existence determination unit 711; and a speed estimation unit 713 estimates speed of the object using a past history of the object position in the world coordinates and a past history of the changed reliability.SELECTED DRAWING: Figure 7

    【課題】路面上の位置推定誤差要因により発生する検出位置誤差による影響を低減可能な情報処理装置を提供する。【解決手段】情報処理装置において、画像を取得し、前記画像に基づき前記画像上の物体位置を検出し、前記画像上の物体位置からワールド座標の物体位置へ変換し、動体追跡(予測部)34では、前記ワールド座標の物体位置に対する信頼度を信頼度算出部710で算出し、検出した前記画像上の物体位置が路面上の位置推定誤差要因の影響を受けるか否かを誤差要因存在判断部711で判断し、前記誤差要因存在判断部711の判断結果に応じて前記物体位置の信頼度を信頼度変更部712で変更し、前記ワールド座標の物体位置の過去履歴及び前記変更後の信頼度の過去履歴を用いて速度推定部713で物体の速度を推定する。【選択図】図7
