In order to ensure the accurate and intuitive transmission of ship navigation information, the compression and transmission accuracy of ship monitoring video image is further improved. due to the complex compression and transmission decompression procedures of traditional ship monitoring video data, image quality is fuzzy, it is difficult to achieve the requirements of accurate transmission of ship data images. Based on the above background, combined with wavelet algorithm, the compression and transmission methods of ship monitoring data are studied and optimized, in order to improve the safety and reliability of data transmission, and achieve the design goal of accurate and fast transmission and image quality recovery. In order to verify the effectiveness of the method, simulation experiments are carried out. the experimental results show that the method of monitoring video data compression and transmission combined with wavelet algorithm can effectively improve the anti-interference ability in the process of image data processing, effectively obtain image features, and quickly carry out image transmission, achieving the goal of accurate and efficient design, and is conducive to ensuring the safety of navigation of ships.
