According to the double-body type unmanned ship for automatically collecting the river and lake bottom mud samples, the double-body type unmanned ship serves as a carrier, and multi-point-position bottom mud sampling can be carried out in rivers and lakes. The device mainly comprises two unmanned ship bodies, the ship bodies are connected through a bridge, and two propellers of the same specification are installed at the tails of the ship bodies; the bottom mud collecting mechanism is mainly used for collecting bottom mud through cooperation of a drilling tool, a multi-section telescopic electric cylinder and a stepping motor; the bottom mud collecting device comprises a worm and gear device, a collecting bottle and the like, and can collect a plurality of bottom mud samples at one time. According to the invention, multi-point sediment sampling based on the double-body type unmanned ship is realized, the double-body type unmanned ship works stably, the problems of time consumption, high risk and the like of manual sediment sampling are solved, the sampling detection efficiency is improved, and the double-body type unmanned ship has wide practicability.

The invention relates to an electric appliance control box used outside a ship body. The electric appliance control box for the exterior of the ship body comprises a box body, a plurality of sets of control connecting ends are arranged on the outer surface of the box body, protective sleeves are arranged on the outer surfaces of the control connecting ends, heat dissipation holes are formed in theouter surfaces of the protective sleeves, and sealing mechanisms are arranged in the protective sleeves. The sealing mechanism can seal the heat dissipation holes, the protective sleeve comprises anouter layer sleeve and an inner layer sleeve, the heat dissipation holes are vent holes formed in the surfaces of the outer layer sleeve and the inner layer sleeve, at least one set of cavity parts and at least one set of solid parts are arranged between the outer layer sleeve and the inner layer sleeve, and the sealing mechanism comprises a sliding block. The vent hole and the sliding block are both located in the cavity part. The electric appliance control box for the exterior of the ship body is simple in structure, convenient to operate, flexible to use, convenient to use, good in sealingperformance, high in heat dissipation effect and convenient to popularize and use.

The invention relates to a monocular camera-based sea surface distance measurement method and system, and the method comprises the steps: measuring the camera pose angle information of a monocular camera and the ship pose angle information of a ship, carrying out the calculation to obtain a camera rotation matrix and a ship rotation matrix, and according to the altitude of the camera, the camera rotation matrix and the ship rotation matrix, acquiring an internal parameter and a distortion parameter of a monocular camera, calculating to obtain a system rotation matrix and a system translation matrix, acquiring a pixel coordinate of an image shot by the camera, further converting the pixel coordinate into a sea surface physical coordinate according to the internal parameter and the distortion parameter of the monocular camera, the system rotation matrix and the system translation matrix, and completing data measurement between a target point and a ship. According to the invention, the problems of high distance measurement difficulty and large distance measurement error in a sea surface distance measurement scene are solved, measurement of data such as the distance between the target ship and the target point, the azimuth angle of the target ship and the width of the ship body in sea surface measurement is realized, and the accuracy of data measurement in sea surface distance measurement is improved.
