Abstract
Description
図1は、第1実施形態による画像投影装置1の構成を示すブロック図である。図1中、信号の流れを一点鎖線の矢印で示す。画像投影装置1は、投影制御装置100、2個のプロジェクタ200A、200Bを含んで構成される。画像投影装置1では、平面のスクリーンに画像を投影するだけでなく、曲面や立体物の表面に画像を投影する、いわゆる、プロジェクションマッピング技術が用いられている。画像投影装置1では、投影される対象物の表面に画像が張り合わされるように対応付けられて投影される。
図7は、第2実施形態による画像投影装置2を説明する説明図である。図7中、信号の流れを一点鎖線の矢印で示す。第2実施形態による画像投影装置2は、航空機(ここでは、ヘリコプター)の表面に塗装を行う場面に適用される。なお、図7における塗装は、迷彩塗装である。
図8は、第3実施形態による画像投影装置3を説明する説明図である。図8中、信号の流れを一点鎖線の矢印で示す。画像投影装置3は、塗装前の航空機(ここでは、ヘリコプター)の表面に画像を投影し、航空機の表面に塗装があたかも施されたかのような外観を提示させる。画像投影装置3は、例えば、ショールームやディーラー店舗などにおいて適用される。
100、300、500 投影制御装置
200A、200B、200C、200D、200 プロジェクタ
