Abstract

PROBLEM TO BE SOLVED: To satisfy the instantaneity of underwater environmental information including fish finding and the mobility of investigation behavior by remote- controlling a crewless surface boat provided with a CCD camera which can execute an underwater photographing action and a bathymeter from the monitoring point of a shore, controlling the investigation behavior and visually displaying an investigation video. SOLUTION: The crewless surface boat 1 which can be radiocontrolled is moored from the monitoring point M of the shore through a mooring rope (signal conductor) 4. Besides, an image pickup/measurement means 3 to which the waterproof CCD camera 31, a light source 32, a sonar and a tidegauge are integrally fitted is hung from the boat 1 by extending the rope 4. By an operator, the boat 1 is conducted to an optional area and the image pickup/ measurment means 3 is lowered to optional depth by instructing and operating a winch on a board 5 to be actuated by using a compact wireless transmitter 2. By instructing the image pickup/measurment means 3 to be actuated and operating the transmitter 2 while viewing a monitor 7, the camera 31 and the image pickup/measurment means 3 are remote-controlled so as to look for a fish or an underwater point being a target.

The purpose of trying to get out of the way is shown. However, regarding exploration actions (including surveys),
In the action column, there is only a description "... after moving the buoy to the site ...", and the action and effect related to mobility and activeness are unknown.

In Japanese Utility Model Laid-Open No. 4-53233 "Underwater observation device", a floating member moored to a signal line from the tip of a fishing rod and an imaging means (CCD camera) supported by the floating member are put into water. The figure shows an example in which an image is displayed at a position near a fishing rod via a signal line. However, since the mooring floating member cannot be propelled by itself, the underwater exploration behavior lacks flexibility (mobility).
