Summary:To provide a viewpoint following video generation device that does not require a motion capture device to measure the position of a display device in real space.SOLUTION: A viewpoint following video generation device 7 includes: three-dimensional position/distance input means 72 for inputting three-dimensional positions/distances for three or more measurement points; real space/virtual space correspondence relation calculation means 75 for estimating a three-dimensional position of a screen in virtual space based on the three-dimensional positions/distances; and viewpoint following video generation means 76 for arranging a virtual camera at a viewpoint position and generating a video corresponding to the three-dimensional position of the screen in the virtual space.SELECTED DRAWING: Figure 3 【課題】実空間における表示装置の位置をモーションキャプチャ装置で計測する必要がない視点追従映像生成装置を提供する。【解決手段】視点追従映像生成装置７は、３つ以上の計測点について、３次元位置・位置が入力される３次元位置・距離入力手段７２と、３次元位置・距離に基づいて、仮想空間におけるスクリーンの３次元位置を推定する実空間・仮想空間対応関係算出手段７５と、視点位置に仮想カメラを配置し、仮想空間におけるスクリーンの３次元位置に対応した映像を生成する視点追従映像生成手段７６と、を備える。【選択図】図３
