摘要
由于现有的智能监测方法的环境质量综合指数较低,为此,研究基于低功耗多旋翼无人机倾斜摄影的近岸海域生态环境风险智能监测.低功耗多旋翼无人机能够灵活深入测区,获取地物全方位的倾斜影像.通过改变焦距,对曝光参数进行调整,自动匹配感光度,避免航片的动态模糊.对近岸海域生态环境采样,计算摄影物距,使无人机依次遍历所有路径点拍摄测区全局.建立模型,对近岸海域生态环境风险进行分析,将获得的生态环境特征数据输入模型中,对环境潜在风险进行识别,获得风险预测结果,从而完成监测.实验结果表明,2009-2023年环境质量综合指数均在90以上,提高了保护区的生态环境质量,使生态系统的健康状况得到改善.
Abstract
Due to the low comprehensive environmental quality index of existing intelligent monitoring methods,thispaper studies the on intelligent monitoring of ecological and environmental risks in coastal areas based on low-power consumption multi-rotor unmanned aerial vehicle(UAV)oblique photography.The low-power multi-rotor UAV can flexibly penetrate deep into the survey area and obtain oblique images of the terrain in all directions.By changing the focal length and adjusting the exposure parameters,the sensitivity is automatically matched to avoid dynamic blurring of aerial photographs.Sampling the ecological environment of the coastal areas,calculating the photographic distance,so that UAV can sequentially traverse all path points to capture the overall measurement area.It establishes a model to analyze the ecological environment risks in coastal areas,input the obtained ecological environment characteristic data into the model to identify potential environmental risks,and obtain risk prediction results to complete monitoring.The experimental results show that the comprehensive environmental quality index between 2009 and 2023 was above 90,which improved the ecological environment quality of the protected area and improved the health status of the ecosystem.
