基于图像识别技术的输电线路卫星山火监测与定位
|
摘要
采用高分四号卫星图像对输电线路山火进行监测。介绍了着火点识别的原理。设计了山火监测系统的构架及其组成功能。分析了森林火险等级与山火发生概率间的关系。采用最小二乘估计法以一次方程的形式拟合了亮度阈值与关键影响参数之间的关系。并提出了着火点位置确定方法以及着火点与输电线路距离的判定方法。实践表明,所设计的卫星山火检测系统能够有效地发现山火并进行预警。
The research on monitoring mountain fire of transmission line by using the image of Gaofen fourth satellite is discussed. The principle of fire judgment is given. The frame and the function of the mountain fire monitoring system are designed. This paper analyzes the relationship between the forest fire risk and the probability of mountain fire. The relationship between the luminance threshold and the key parameters is fitted in the form of one order equation by using least square estimation method. And the method to determine the position of fire position and calculus the distance between the fire position and transmission line is given. The result shows that the design of the satellite fire detection system can effectively detect the mountain fire and carry out early warning.
