A laser spot detection algorithm for fire extinguishing training system

为有效解决激光灭火训练系统的激光光斑中心检测问题,在分析传统检测方法的基础上,提出了一种简单实用的光斑检测算法。该算法首先对采集图像进行高斯滤波,消除噪点;然后在图像的HSV颜色空间提取白色和红色分量并二值化;其次在待检测点的周围以光斑尺寸大小为依据选取四个参考点构造十字检测窗口,识别光斑区域;最后根据矩形形心计算光标中心。该方法计算简单,无需背景预测,可满足不同背景、不同光照环境下的激光光斑中心检测。实验结果表明了该算法的有效性。

To solve the problem of laser spot center detection problem in fire extinguishing training system,a simple and practical detection algorithm is presented based on the analysis of tradition detection methods. Firstly,the captured image is filtered by Gaussian filter to remove noise. Secondly,white and red color component are retrieved in HSV color space. Thirdly,a cross window around candidate point is constructed to identify spot according to the size of laser spot. Finally,laser spot center is calculated based on the rectangle which is surround spot. The method is simple,does not need background prediction,and can be applied to multiple backgrounds or complex illumination environment. The experimental results show that the algorithm is effective.
