摘要

针对明渠水位获取问题

提出了一种基于图像的明渠水位自动测量新方法。在由颜色信息实现自适应提取标尺区域的基础上

根据标尺特性采用改进的边缘检测算法对特征图像进行分割处理

获取水位高度信息。水位获取实验证实:该方法不受摄像头安装角度、渠水浑浊度和温度的影响

测量的水位高度误差可控制在1 cm以内

具有很强的鲁棒性。

Abstract

A new automatic measurement method for canals water level is proposed based on image processing

aiming at problem of canals water level acquisition.On the basis of achieving self-adaptive extraction scaleplate area through color information

according to features of scaleplate

use improved edge detection algorithm to segment feature images

and access water level information.The water level acquisition experiment confirms that this method is not affected by cameras installing angle

canals water turbidity and temperature

and measured error of water level height can be controlled within 1 cm

it has strong robustness.
