To provide a video compositing device which creates a high-definition continuous video image in a part where video images are switched along a path input by a user.SOLUTION: A video composing device includes: a city video image acquisition part which acquires a city video image imaged by an entire celestial sphere camera; a frame position estimation part which estimates positions on the map of each of a plurality of frame images constituting the acquired city video image; a photographing path creation part which creates an imaging path of the entire celestial sphere camera on the basis of the estimated position; an intersection frame image detection part which detects intersection frame images of switching a city video image from one photographing path to other photographing path in an intersection where the plurality of creased photographic paths cross each other, from the plurality of frame images whose positions are estimated on each of the imaging paths; a frame image connection part which connects the detected intersection frame images so as to be continuous in the intersection; and a combined city video image output part which outputs a combined city video image of the input path including the connected intersection frame image.SELECTED DRAWING: Figure 1

    【課題】ユーザの入力した経路に沿って映像の切り替わる箇所で連続性があり高精細な映像を作成する映像合成装置を提供する。【解決手段】映像合成装置は、全天球カメラによって撮影された市街映像を取得する市街映像取得部と、取得した市街映像を構成する複数のフレーム画像それぞれの、地図上の位置を推定するフレーム位置推定部と、推定された位置に基づいて、全天球カメラの撮影経路を作成する撮影経路作成部と、作成された複数の撮影経路が互いに交差する交差点において一の撮影経路から他の撮影経路に市街映像が切り替わる交差点フレーム画像を、それぞれの撮影経路において位置が推定された複数のフレーム画像から検出する交差点フレーム画像検出部と、検出された交差点フレーム画像を、交差点において連続するように接続するフレーム画像接続部と、接続された交差点フレーム画像を含む入力経路の合成市街映像を出力する合成市街映像出力部と、を備える。【選択図】図1
