Underwater image transmission method and system based on wireless underwater acoustic communication technology

Abstract

The invention relates to an underwater image transmission method and an underwater image transmission system based on a wireless underwater acoustic communication technology. The method comprises thesteps of marking a plurality of data packets acquired by cutting underwater image data; sequentially sending the data packets to a receiving end according to marks; when the data packet is failed to receive, resending the data packet with the corresponding mark according to the mark of the fed back data packet, until all the data packets are successfully received. According to the method and the system provided by the invention, underwater image transmission is achieved, the data packet with a transmission mistake is fed back, and the data packet with the corresponding mark is sent again, so that data receiving quality is improved, and definition and completeness of underwater images acquired latterly are ensured. The underwater image transmission system provided by the invention is basedon wireless underwater acoustic communication, and has the advantages of low underwater acoustic communication cost and high flexibility compared with a cable wire which as the disadvantages of beingheavy, easy to damage and difficult to maintain. In an underwater environment, underwater sound is used as an underwater wireless communication means so as to be more practical and effective.

Description

technical field [0001] The invention relates to the technical field of underwater communication, in particular to an underwater image transmission method and system based on wireless underwater acoustic communication technology. Background technique [0002] The ocean is rich in resources, and the realization of ocean observation, resource exploration and development is one of the most concerned issues of all oceanic countries. In recent years, underwater acoustic communication has made great progress due to the continuous expansion in the field of marine information. In the military, networked underwater acoustic communication technology continues to show its importance in the monitoring and collection of marine military intelligence, the monitoring of ports and near-shore waters, especially underwater reconnaissance and multi-node cooperative detection, cluster management command and coordination, etc. . The continuous expansion of the current ocean monitoring range and ...
