To provide a remote operation type underwater movement body capable of projecting a stable video under water.SOLUTION: A remote operation type underwater movement body includes a frame body 10 with a waterproof function which incorporates a projection device 20 for displaying a projection video on an external projection surface, a projection video correction part for correcting the projection video, a light source 30 using the projection device 20 and a flowing water tube 50 for cooling the light source 30 and through which the flowing water tube 50 penetrates. The projection video correction part corrects the projection video, so that the frame body 10 has predetermined size and shape on the projection surface according to a distance from the projection device 20 to the projection surface and an angle formed by the projection surface and the optical axis of light with which the projection surface is irradiated, when the projection video is enlarged or reduced, or deformed by the movement in the tube axial direction of the flowing water tube 50.SELECTED DRAWING: Figure 1

    【課題】水中で安定した映像を投影可能な遠隔操作型水中移動体を提供する。【解決手段】投影映像を外部の投影面に表示する投影装置20と、投影映像を補正する投影映像補正部と、投影装置20に使用する光源30と、光源30を冷却するための流水管50と、を内蔵し、流水管50を貫通させた防水機能を備えるフレーム体10を有し、投影映像補正部は、フレーム体10が流水管50の管軸方向の移動により投影映像が拡大若しくは縮小、又は、変形する場合において、投影装置20から投影面までの距離及び投影面と当該投影面に照射する光の光軸との角度に応じて、投影面で所定の大きさ及び形状となるように投影映像を補正する。【選択図】図1
