基于数字图像处理的冷却塔成雾量估算方法研究

Discussion on Estimation Method of Fog Formation in Cooling Tower Based on Image Processing

除雾技术可以减少冷却塔雾羽流对周边环境的影响,成雾量是判断除雾效果优劣的关键参数.本文采用图像分析方法,通过建立成雾实验台,拍摄并提取了雾羽流连续单帧图像,分析了白雾轮廓图像特征,估算了轮廓包裹面积随时间的变化情况;并探讨了通过特征点追踪雾流速度的可行性.该方法可为基于图像分析的成雾量估算奠定基础.

Fogging technology can reduce the impact of cooling tower fog ume on the surrounding environment,and the amount of fog is the key parameter to judge the quality of defogging effect.By adopting the image analysis method,the change of the contour wrapping area over time is estimated,and the feasibility of tracking the fog flow velocity is discussed through the feature points.This method can lay the foundation for the estimation of fog formation amount based on image analysis.
