Specifically, in order to realize the movement of the auxiliary device for underwater shooting, the underwater robot 13 is further included, and the underwater robot 13 can drive the auxiliary device for underwater shooting to reach the underwater set position.
This scheme simple structure when the device is arranged in the surface that needs shot, pours into the clear water into through first water pump, can extrude the muddy water in the housing, makes 8 waters before the camera keep comparatively clear water matter basically. And the clear water injected by the water pump can wash away impurities such as sludge on the surface to be shot, the surface to be detected can be shot more clearly, and the problem that the underwater surface to be detected cannot be observed due to the covering is solved. The flexible material shell with good elasticity is adopted, so that the device can be located on the irregular surface, turbid water is extruded out from the gap, and the shooting and detection of the irregular surface in a turbid water area can be completed.
When the conditions do not allow the connection of a high-pressure water pump on the shore, the water pump provided with the filtering device 15 and arranged on the underwater robot 13 can be used, the filtering device 15 filters turbid water into clear water, and the water is input into the housing through the water pump. The flexible and changeable underwater clear shooting method is realized.
