Problems solved by technology

Affected by ocean currents and the heave movement of the mother ship, the attitude of the deep-sea camera system will change continuously during the operation, which seriously affects the quality of data collection
In addition, due to the ups and downs of the seabed terrain, in order to ensure the navigation of the system at a fixed altitude, it is necessary to continuously retract and retract the winch manually to prevent the system from being hit, which also greatly increases the difficulty of the operation

Embodiment 1

[0040] Embodiment 1, this embodiment proposes a kind of deep-sea camera system, such as figure 1 and figure 2As shown, it includes a frame 1, a pitching attitude adjustment mechanism 2, a hydraulic pump station 3, a fixed height control mechanism 7 and an electronic cabin 10. The electronic cabin 10 is equipped with a main control board and an attitude sensor, and the hydraulic pump station 3 and the electronic cabin 10 pass through The cabin fixing frame 8 and the cabin connecting rod 9 are fixed on the frame 1; an altimeter 4, a camera 5, a lighting lamp 11, a camera 12, a counterweight 6 and a depth gauge 13 are also fixedly installed on the frame 1, and the camera 5 is used for shooting Submarine photo, camera 12 is used for recording subsea video, illuminating lamp 11 is used for lighting, depth meter 13 is used for the working depth of real-time monitoring camera system, altimeter 4 real-time monitoring system's height from the bottom, depth meter 13 and altimeter 4 and...

Embodiment 2

[0049] Example 2, such as Figure 8 and Figure 9 As shown, the present invention also discloses a method for controlling a deep-sea camera system, which specifically includes the following steps:

[0050] Step A, pitch attitude adjustment:

[0051] (A1) Real-time monitoring of the pitch angle of the camera system by the attitude sensor;

[0052] (A2) The passive attitude adjustment mechanism adjusts the pitch angle of the system in real time, and judges whether the pitch angle of the camera system exceeds the effective adjustment range of the passive attitude adjustment mechanism. If it exceeds, perform step A3; if not, continue to adjust the pitch of the system based on the passive attitude adjustment mechanism horn;

[0053] (A3) Control the active attitude adjustment mechanism through the main control board to adjust the pitch angle of the system to the desired range.

[0054] Specifically, in this embodiment, the expected range of the pitch angle of the camera system ...

Abstract

The invention discloses a deep sea camera system and a control method thereof. The camera system comprises a pitch attitude adjusting mechanism, a hydraulic pump station, a fixed height control mechanism and an electronic cabin. The pitch attitude adjusting mechanism comprises an active attitude adjusting mechanism and a passive attitude adjusting mechanism, the passive attitude adjusting mechanism is installed on a side wing of the active attitude adjusting mechanism, and the hydraulic pump station and the electronic cabin are fixed on a frame through a cabin body fixing frame and a cabin body connecting rod. According to the scheme, through the combination of the passive attitude adjusting mechanism and the active attitude adjusting mechanism, the active and passive adjustment of the pitch attitude of the system is realized; through the fixed-height control mechanism, the self-adaptive fixed-height control over the height of the system away from the bottom is achieved, and the operation efficiency, the movement stability and the data collection quality of the system are greatly improved. Meanwhile, in combination with a deep-sea camera system control strategy, the self-adaptive adjustment of the system stability can be realized according to the real-time changes of the attitude and height of the system, and the intelligent level of the system is improved.

Description

technical field [0001] The invention relates to the technical field of deep-sea imaging, in particular to a deep-sea imaging system and a control method thereof. Background technique [0002] The ocean occupies about 70% of the earth's surface, and it contains inexhaustible resources and energy for human beings, especially in the deep sea area, where there are seabed minerals to be developed, underwater life to be studied, marine environment to be investigated, and drones to be deployed. defense area. At present, deep-sea photography has become a very important means in the research work of deep-sea submarine exploration. As a new geological survey method, deep-sea photography can be used to observe seabed topography and landforms more intuitively. Censuses play an important role. [0003] The current deep-sea camera system has no power source at all, and is mainly towed by the mother ship. With the continuous deepening of deep-sea surveys, higher requirements are placed ...
