| 摘 要： | 在分析MODIS火灾检测通道的基础上，结合图像信息增强处理法、阈值法等多种火点识别处理算法，设计出了一套通过对遥感影像中红外通道的亮度、温度值进行阈值处理的森林火点识别流程，辅以一系列识别和修正方法，能有效地排除各种干扰，识别出火点。实验表明，该方法的识别率在60％以上。

| Abstract: | A fire detection flow is designed based on analyzing MODIS fire examination channel,with a kind of fire point identification methods,for example image information enhancement process and threshold to process the brightness and temperature of mid-infrared channel from remote sensing images by threshold.With the help of a series of recognition and correction methods,the flow can exclude much disturbance and identify the fire point effectively.The recognition rate is up to 60% according to the experimental res... |
