摘　　要：针对早期投放的人工鱼礁在持续跟踪监测手段上不够完善、维护方式欠缺等问题,本文提出一种基于声光组合技术的人工鱼礁探测方法,可在满足礁区生态效益的基础上,对人工鱼礁进行快速的探测。首先,利用侧扫声呐系统进行大范围海域的人工鱼礁精准定位,再利用水下机器人搭载多波束成像声呐,对鱼礁目标进行精准索航;其次,提出一种适合水下图像增强的红色通道算法,实现对鱼礁表面摄像图像的清晰成像,同时结合声呐数据评估人工鱼礁区鱼群密度情况,为人工鱼礁探测以及增殖效果评估探索出一种科学高效、可操作、可复制的方法;最后,选择具有水域大、水层深、建设时间长、礁体投放位置不够精准,探测难度大等特点的国家级小星山海洋牧场人工鱼礁区为探测区域作为试验对象,通过本方法从周期监测策略、过度捕捞、养殖侵占、增殖放流等4个方面进行试验,旨在优化人工鱼礁区的生态环境、提升渔业资源增殖效果,形成安全、现代化、具备示范带动的海洋牧场。In response to the problems of incomplete continuous tracking and monitoring methods and lack of maintenance methods for early deployment of artificial fish reefs,this paper proposes a method based on sound and light combination technology for rapid detection of artificial fish reefs while meeting the ecological benefits of the reef area.Firstly,a side scan sonar system is used to accurately locate artificial fish reefs in a wide range of sea areas,and then underwater robots equipped with multi beam imaging sonar are used to accurately navigate fish reef targets.Secondly,a red channel algorithm suitable for underwater image enhancement is proposed to achieve clear imaging of surface camera images of fish reefs.At the same time,sonar data is used to evaluate the density of fish schools in artificial fish reef areas,exploring a scientifically efficient,operable,and replicable method for detecting and evaluating the proliferation effect of artificial fish reefs.Finally,the national level Xiaoxingshan marine ranch artificial fish reef area with characteristics such as large water area,deep water layer,long construction time,inaccurate placement of reefs,and high detection difficulty was selected as the experimental object.Through the methods in this article,experiments were conducted from four aspects:periodic monitoring strategy,overfishing,aquaculture invasion,and proliferation and release,aiming to optimize the ecological environment of the artificial fish reef area and improve the proliferation effect of fishery resources,Establish safe,modern,and demonstrative marine pastures.
