Problems solved by technology

[0005] In practical applications, acoustic means have high measurement accuracy but high cost and are difficult to continuously observe in a large area; while optical means are limited by the attenuation effect of light itself in seawater, and its detection depth is very limited compared with acoustic waves
Among them, although passive optical remote sensing can use sunlight for large-scale measurement, the measurement accuracy is poor; active optical remote sensing can reach an average error of 0.1m in the water depth range of 0-15m, but limited by the flight platform, its cost is high, and it cannot be continuous in a wide range to observe

Abstract

This article is about a method and device for obtaining seabed information. The method includes: acquiring image information of an echo signal obtained by a ship-borne fish finder identifying the sea bottom; determining where the sea bottom boundary is located in the image of the echo signal according to energy information of the image information of the echo signal area; determine seabed boundary information in the area where the image of the echo signal is located.

Description

technical field [0001] This article relates to the field of information processing, in particular to a method and device for obtaining seabed information. Background technique [0002] The seabed topographic measurement means in related technologies can be divided into two categories, including the use of acoustic means and the use of optical means; where: [0003] Acoustic means is to use professional surveying and mapping sonar for measurement. For example, the equipment used can be echo sounder, multi-beam sounder, side-scan sonar, or underwater robot; [0004] Optical means is the use of active or passive remote sensing observations. [0005] In practical applications, acoustic means have high measurement accuracy but high cost and are difficult to continuously observe in a large area; while optical means are limited by the attenuation effect of light itself in seawater, and its detection depth is very limited compared with acoustic waves. Among them, although passive ...
