System for sensing position variation of submarine landform coordinates and water depth information through reference points setting

The purpose of the present invention is to maintain the horizontality of an underwater detector which explores submarine topography by connecting and towing an exploring vessel with the underwater detector using a wire and by connecting a power line and a communication line, and to prevent cutting or a short circuit during winding. A system prepared by the present invention comprises a lifting device, a submarine photographing device, and a submarine image correcting device. The lifting device comprises: an exploring vessel having an exploring vessel body which moves on the water, a supporting body which is installed in the upper part of the exploring vessel body in a vertical direction, a horizontal body which is installed in the supporting body in a horizontal direction, and multiple guide bodies; a driving device which rotates the supporting body; a winding drum which is installed in the exploring vessel body to be able to rotate; a driving motor which rotates the winding drum; and a lifting wire which is wound on the winding drum. The submarine photographing device comprises: a detector body which is towed by being connected with the lifting wire; an ultrasonic sensor which is installed in the detector body; an underwater camera which is installed in the detector body; a location tracking device which is installed in the detector body; and an underwater detector having a transmitting unit which transmits an ultrasonic signal, an image signal, and a location signal. The submarine image correcting device comprises: a correcting device body which is installed in the exploring vessel of the submarine photographing device; a storing unit which stores submarine images; a receiving unit which receives the ultrasonic signal, the image signal, and the location signal from the transmitting unit in the underwater detector; a control unit which generates submarine images by receiving the ultrasonic signal, displays submarine images by receiving the image signal, displays the location of the submarine images by receiving the location signal, and performs deletion and correction; an input unit which inputs a control signal to the control unit; and an output unit which displays the submarine images.
