時間同期式プロジェクタカメラシステムを用いた水中鮮明画像の取得技術

抄録

We investigated the feasibility of using a time-synchronized projector-camera system (SyncProCam) to capture clear underwater images. Underwater images can be blurred owing to the scattering of light by floating objects in water. The SyncProCam allows the camera to only receive projector light reflected from a specific area in space, that is, the area where the object is located. In this study, we presented slit light images to the SyncProCam and a general-purpose camera, and compared the pixel response values obtained by the systems. The experimental results show that the SyncProCam can acquire a higher contrast signal with a lower signal-to-noise ratio.
