AI Technical Summary

Technical Problem

Existing methods for inspecting submarine pipelines rely on prior information, resulting in low reliability and issues such as insufficient coverage, tracking interruption, positioning deviation, or target loss. Furthermore, manual path planning is prone to errors and carries a high risk of communication packet loss.

Method used

The search path is planned based on the minimum parameter set obtained by the underwater vehicle. The search and precise tracking of the subsea pipeline area are performed by using the path point indexing method. The search and precise tracking of the subsea pipeline area are performed cyclically until all path points are completed.

Benefits of technology

It reduces reliance on prior information, minimizes the risk of manual input and communication packet loss, improves the reliability and coverage integrity of inspections, and avoids the loss of target tracking.

Abstract

本申请公开了一种基于水下航行器的海底管线巡检方法及系统、介质、终端,涉及水下机器人技术领域,主要目的在于改善现有管线巡检方法可靠性低的问题。本申请实施例通过控制水下航行器在巡检前基于最少参数集实时规划搜索路径点,降低了对先验信息的依赖,避免了因先验信息有误而导致的预规划航行路径不准确的问题;同时由于无需人工输入以及传输庞大的预规划航行路径点文件,降低了输入出错的风险以及通信丢包的风险;并且在巡检过程中,基于检测到海底管线的次数以及跟踪丢失海底管线的次数,循环执行海底管线区域搜索行为以及海底管线精确跟踪行为,避免了目标跟踪丢失但水下航行器依旧继续执行原有路径的情况。
