比较了3种不同的红外热成像仪林火识别算法,提出了配置林火自动识别算法参数的林火野外测试方法,并利用该方法在珠海进行了测试实验。通过测试实验发现红外热成像仪在夜间分辨火点能力高于白天。3种林火识别算法比较结果为:阈值判定法具有较高灵敏性,但易受干扰;邻域阈值判定法抗干扰能力有所增强,但监测距离会有所缩短;均值对比判定法抗干扰能力较强,但监测距离最短。
Comparison of three different infrared thermal imager forest fire recognition algorithm, proposed forest fire automatic identification algorithm parameters of the forest fire field test method, and the use of the method in Zhuhai conducted a test experiment. Through the experiment, it is found that infrared thermal imager can distinguish fire point at night and daytime. The results of three kinds of forest fire recognition algorithms are as follows: the threshold decision method is highly sensitive but susceptible to interference; the anti-interference ability of neighborhood threshold decision method is enhanced, but the monitoring distance will be shortened; mean comparison judgment method anti-interference Strong ability, but the shortest monitoring distance.
