基于机器视觉技术的水表新型检定方法
A Novel Water Meter Calibration Method Based on Machine Vision Technology
【摘要】 将机器视觉技术应用到水表检定系统中,通过固定在被检水表上方的高速高分辨率摄像机,动态获取运行中的水表图像,用颜色特征和背景高斯拟合建模结合的算法实现水表指针的准确定位,将图像实时转换成数字读数,并解决水珠、气泡等对读数干扰的问题,实现水表高效率全自动检定。
【Abstract】 The machine vision technology applied to the water meter calibration is discribed.Several high speed and high resolution cameras are installed at the top of the checked meter to dynamically access the running water meter image.The meter pointer is accurately positioned using color feature modeling and background Gaussian fitting methods.Machine vision approaches are used to convert the captured images into digital readouts.Encountered problems such as blurred surface and air bubble interfere are overcome.The developed system realizes high efficient automatic water meter verification.
