火焰长度的图像测量方法研究

Image measurement method for flame length

提出了一种火焰长度的测量方法。该方法利用彩色面阵CCD相机获得火焰图像;根据火焰辐射强度和亮度之间的理论关系,提出了基于图像亮度来提取火焰图像;依据提取的火焰图像,提出了一种确定火焰边界和计算火焰长度的算法。最后用蜡烛在实验室进行了试验验证。利用M atlab提取火焰亮度图像,并进行了滤波处理;利用V isual C#编程技术,依据所提取的火焰边界和长度计算方法,得到火焰实际长度。该方法代替了传统的手工测量,操作方便、简单。试验表明该方法能达到理想的测量结果。

A flame length measurement method is introduced in this paper.The image is obtained by color matrix CCD and is extracted based on brightness according to the relationship between radiant intensity and the brightness of the flame.The algorithms to determine the flame boundary and compute the flame length are designed based on the extracted image.Finally,the test experiment is evaluated with the candle in the laboratory.The brightness image is extracted and filtered by Matlab.The actual flame length is obtained in Visual C#.The method is more convenient and simpler than traditional manual measurement.
