摘要
介绍了现有的MODIS在林火监测中的理论算法,但因其受地域条件、天气状况和季节变化的影响,对四川、重庆地区可能会造成漏判或误判。本文以四川地震局提供的MODIS数据为基础,研究如何合理改进原有算法,得出一种适宜于四川、重庆地区的林火识别算法。实验表明,本文得出的算法能够有效地监测森林火灾。
The article introduce the existing MODIS theoretical algorithms in forest fire detection, but it is under the influence of region condition, the weather condition and the season variety, the algorithms may be do omit detection or mistake detection to SiChuan and ChongQing area. The article research that how to improve existing algorithms in reason base on the data provided by Sichuan Earthquake Bureau, and educe a forest fire detection algorithms applicated to Sichuan and ChongQing area. The experiment show that the forest fire detection algorithms have basically available.
