To provide a measurement system, vehicle, measurement method, measurement device and measurement program for peripheral object, capable of accommodating sudden appearance of an object.SOLUTION: A measurement system includes an imaging device 2 which picks up an image of an object including a first image at a time t-1 and a second image at a time t at 100 fps or more and an information processor 3 which extracts a plurality of first feature points, that is, feature points relating to an object in a first image, calculates an optical flow thereof, extracts a plurality of second feature points relating to the object in a second image, calculating an estimated movement destination in the second image of the first feature point on the basis of the optical flow, calculates feature point information including new appearance or disappearance of a feature point by comparing the estimated movement destination to the second feature point and measures physical quantity concerning the movement of the object.SELECTED DRAWING: Figure 1

    【課題】対象物の突然の出現等にも対応することができる、周囲の対象物の計測システム、車両、計測方法、計測装置及び計測プログラムを提供する。【解決手段】計測システムは、時刻t−1における第1の画像と時刻tにおける第2の画像とを含む対象物の画像を100fps以上で撮像する撮像装置2と、第1の画像において対象物に係る特徴点である第1の特徴点を複数抽出するとともに、そのオプティカルフローを演算し、第2の画像において前記対象物に係る特徴点である第2の特徴点を複数抽出し、第1の特徴点の第2の画像における推定移動先をオプティカルフローに基づいて算出するとともに、これらの推定移動先と第2の特徴点とを比較することで、特徴点の新たな出現又は消滅を含む特徴点情報を算出し、特徴点情報に基づいて、対象物の移動に関する物理量を計測する情報処理装置3とを備える。【選択図】図1
