摘要
水位监测对于流域水资源综合治理和航运具有重要意义,随着机器视觉技术的发展使得图像法水位检测有望代替人工观测水尺。本文简述了图像法水位检测的发展历程与现状,对比多种水位检测方法说明图像法的优势,总结图像法水位检测的基本流程,分析其中的三大关键步骤:标尺分割与畸变矫正,水位线检测和水位值换算,对每个步骤国内外的相关方法和研究发展进行综述。最后,对现阶段图像法水位检测面临的问题进行总结及对下一步研究方向进行展望。
Water level monitoring is of great significance to the comprehensive management of water resources and navigation.With the development of machine vision technology,the image water level method is expected to replace observing the water gauge.Firstly,the history and the situation of water level detection are briefly described.The advantages of image method are illustrated by comparing various water level detection methods.Then,three key steps of image water level detection are analyzed:water gauge segmentation and distortion correction,water level detection and water level conversion.The methods and development of each step for each step are summarized at home and abroad.Finally,the problems of image water level detection at present are summarized and the future direction is prospected.
