Description

Technical Field

[0001] The present invention relates to the technical field of ocean image target recognition, and in particular to an ocean image target recognition system, method and buoy device based on satellite communication. Background Art

[0002] Based on the development and utilization of the ocean by human beings, in scenarios such as national defense security, maritime traffic management, marine resource investigation, marine monitoring and protection, maritime search and rescue, coastline patrol and illegal activity monitoring, it is necessary to identify and judge abnormal targets appearing on the ocean surface. If manpower is used for patrol, it will consume a lot of manpower and material resources. Therefore, the research on remote image acquisition and target recognition technology of the ocean surface is particularly important.

[0003] A Chinese patent with publication number CN107369283A discloses an ocean anchored buoy warning system and method based on image recognition. The system includes multiple camera devices installed around the ocean anchored buoy. The combined camera of the multiple camera devices forms a 360° panoramic image for realizing comprehensive monitoring around the ocean anchored buoy; a distance measurement module, which uses an image processing method to measure the distance between the target object in the image and the ocean anchored buoy based on the images taken by the multiple camera devices around the ocean anchored buoy. The target object includes suspicious ships and suspicious persons; a voice broadcast and warning module, when the result of the distance measurement module is less than the set distance, an alarm message is sent to the shore station workstation via satellite communication, and the shore station staff has a voice call with the suspicious person via satellite communication, or the shore station staff broadcasts the buoy publicity information to the suspicious person via satellite communication.

[0004] In the above-mentioned prior art, it is necessary to install a plurality of camera devices around the buoy to complete 360-degree all-round image acquisition in order to realize comprehensive monitoring around the buoy; at the same time, no image stabilization measures are taken, and it is difficult to ensure that stable image data is captured in the complex environment on the sea surface. The distance between the target object and the buoy in the image is calculated only by image processing methods, and it is difficult to ensure the recognition accuracy, which is easy to cause misjudgment. Moreover, only the target distance is reported to the ground monitoring platform without more detailed information of the target, and it is impossible to provide strong support for subsequent actions.

[0005] Therefore, the present invention aims to provide an ocean image target recognition system, method and buoy device based on satellite communication to solve the above-mentioned related problems. Summary of the invention

The control processing module outputs an image acquisition control signal based on a preset acquisition instruction. The balance rotation unit in the image acquisition module controls the acquisition unit to rotate according to the acquisition interval based on the image acquisition control signal, thereby realizing omnidirectional acquisition of the ocean image. At the same time, the target recognition unit in the image acquisition module identifies abnormal targets in the ocean image, and uses a neural network algorithm to extract feature information of the abnormal targets to obtain target feature information.

The plurality of solar panels 301 are laid on the top surface of the buoy platform 1, and the MPPT controller 302 and the lithium battery pack 303 are placed in the cavity 2. The solar panels 301 absorb solar energy to charge the lithium battery pack 303, and the lithium battery is discharged to the control processing device 4 after being charged. At the same time, it should be noted that the rotation stabilizer 5 adopts a conventional camera three-axis stabilized gimbal, and the image acquisition device 6 adopts a high-definition camera.

The target recognition device is embedded with a neural network algorithm that can perform target recognition on the collected image, and this technical means is a conventional technical means. At the same time, it should be noted that the attitude monitoring device 10 includes a gyroscope, an accelerometer and an electronic compass.

If the low-orbit satellite link network access fails because the satellite has not passed, the high-orbit satellite communication link network access is performed; when the satellite communication link is normally established, first determine whether there is any unreported data stored locally, and if so, first transmit the unreported data back to the ground monitoring platform; adjust the direction of the image acquisition device 6 by controlling the rotation stabilizer 5 and complete the ocean image shooting, the original ocean image data will be input into the target recognition device for target recognition, and after the recognition is completed, the image data and target feature information are sent to the control processing device 4; control The processing device 4 determines the data processing scheme according to the satellite network access situation: if the low-orbit satellite communication link is successfully connected to the network, the original ocean image data and the target feature information are simultaneously transmitted back to the ground monitoring platform; if the low-orbit satellite link cannot be connected to the network but the high-orbit satellite communication link is normally connected to the network, only the target feature information is transmitted back to the platform; if both the low-orbit and high-orbit satellite communication links are not successfully connected to the network, the data is stored in the data storage device; after completing the image data acquisition, target identification and data transmission or storage in one direction, the rotation stabilizer 5 is controlled to rotate horizontally to the next direction to complete the same processing operation until the horizontal all-round detection and identification are completed; after the single detection and identification task is completed, the control processing device 4 controls all functional modules to power off, and then sets the RTC counting cycle and enters the standby mode.
