Problems solved by technology

[0007] The present invention is to solve the problem that the existing side-scan sonar image interpretation method can only read the changes of speed information, course information and roll information in digital form through software, and cannot observe their changes intuitively and as a whole situation, leading to the problem of high judgment error rate, thus providing a side-scan sonar image-assisted interpretation method based on UUV

specific Embodiment approach 1

[0026] The specific embodiment one, UUV-based side-scan sonar image auxiliary interpretation method, the purpose of the present invention is achieved in this way:

[0027] Changes in speed, heading and roll affect the side scan sonar image. All other factors being equal, the faster the sonar passes over the target, the shorter the target will appear on the record. Steering the sideways direction of the inboard transducer will change the angle to scan a small location on the seafloor. In contrast, the outer transducer will sweep across a large sector.

[0028] However, we can only read the changes of speed information, heading information and roll information in digital form through software, and cannot observe their changes intuitively and as a whole. The present invention proposes a method for visualizing the speed information, course information and roll information, so as to realize the intuitive integration of the above-mentioned data interpretation and prepare for the n...

Abstract

A UUV-based side-scan sonar image auxiliary interpreting method relates to the technology of side-scan sonar image auxiliary interpretation, and solves the problem of high determination error rate of a conventional method. Information is divided into different area blocks according to the distance between two sampling points based on UUV recorded speed information, course information, rolling information and corresponding latitude and longitude information, quantifying the speed information, the course information and the rolling information into different color grades, filling corresponding colors in the corresponding area blocks to form color images of different color depths, dividing the original side-scan sonar image, and inserting the processed color images into the divided side-scan sonar image. A speed graph, a course graph, a rolling graph and a side-scan sonar image are combined, and the purpose of auxiliary interpretation is achieved.

Description

technical field [0001] The invention relates to UUV-based side scan sonar image aided interpretation technology. Background technique [0002] UUV (Unmanned Underwater Vehicles, referred to as UUV) is also called underwater unmanned vehicle. With the continuous upgrading of UUV, its functions will also increase. Large amounts of data are available. UUV carries a side-scan sonar, which has great advantages over the traditional towed sonar of surface ships. UUV-based side-scan sonar image acquisition overcomes the towed sonar's impact on the speed change of the towed fish floating up and down. Effects produced by sonar imagery. At the same time, UUV's submerged operation reduces the impact of wind and waves on the attitude of surface ships, thereby reducing the impact on the side-scan sonar image effect. [0003] However, the images scanned by UUV carrying side-scan sonar still have image distortion, mainly due to the complex underwater environment, which leads to changes i...
