基于图像处理和识别技术的灼热丝火焰检测系统

摘要

简介：为了提高灼热丝火焰高度测量的准确性，利用图像处理软件MATLAB对火焰图像进行灰度提取，根据灰度图像中火焰与背景的亮度差异，采用高斯—拉普拉斯算子进行火焰图像边缘的提取，采用工件尺寸的光学测量方法计算火焰高度。经过与传统方法的比较试验表明，该方法所测火焰高度数据准确，用于灼热丝火焰高度的检测是可行的。%In order to improve the glow-wire flame height measurement accuracy, it uses image processing software MATLAB to extract from grayscale the flame image. It uses the Gauss-La-place operator flame image edge extraction, according to flame and background brightness dif-ferences in grayscale images. And it uses the method of optical measurement of the size of the workpiece to calculate the height of the flame. Comparative test with a conventional method showed that the flame as measured by the method highly accurate data for the glow-wire flame height detection is feasible.
