摘要
提出一种基于图像处理技术并利用相机光学成像原理的线路覆冰厚度测量方法,利用相机小孔成像原理的测量模型,能够非常精准地测算出导线覆冰厚度。利用人工拍摄目标图像,用MATLAB仿真软件将目标图像经过图像灰度化、滤波除噪、图像增强等图像预处理后,对图像进行边缘检测,在目标覆冰导线直径方向选取一组像素坐标点,可得出像素坐标差vv'。
This article puts forward a kind of based on image processing technology,the use of the camera line ice thickness measurement methods of optical imaging principle,using the camera hole imaging principle of the measurement model,It can accurately measure the thickness of wire icing.The target image is taken manually,and the target image is preprocessed by image grayscale,filtering and de-noising,and image enhancement with MATLAB simulation software.The edge of the image is detected,and a group of pixel coordinate points are selected in the direction of the diameter of the target ice-covered wire,and the pixel coordinate difference vv'can be obtained.
