Abstract

The invention discloses a side-scan sonar image processing method and device. The method comprises the following steps: 1) setting a sliding window M for an acquired side-scan sonar image to perform sliding caching; 2) carrying out denoising processing on the cached image; 3) image layering enhancement; taking the denoised image as an input signal of bilateral filtering layering, calculating high-frequency image data of single-line frame data based on cache block filtering data, and performing weighted fusion on the high-frequency image and an original data image to realize image enhancement; and 4) carrying out gray scale equalization processing on the enhanced image. According to the method, the details of the image are effectively enhanced through processing, and the real-time performance of processing is ensured.

Description

technical field

[0001] The invention relates to image processing technology, in particular to a side scan sonar image processing method and device. Background technique

[0002] Side-scan sonar is an effective detection equipment for underwater detection sonar. It mainly transmits acoustic signals through acoustic transducers and collects scattered echo signals for further processing to form underwater imaging system equipment. Generally, side-scan systems use high-precision The AD module collects the data and uses the unique imaging algorithm to process it to form the original side-scan image. Due to the complex underwater environment, the original contrast of the image is low, the distribution is concentrated, and the dynamic range is large, which is not suitable for human observation and display software. Real-time display, it is urgent to deal with it effectively. Therefore, the study of an effective real-time processing method for side scan sonar images will effectivel...
