摘要: 贝叶斯网络是一种不确定性知识的推理和描述技术,针对遥感数据的复杂性和不确定性,该文提出了一种基于贝叶斯网络模型的遥感数据推理和描述技术。文中利用 2002年春季中-日亚洲沙尘暴项目的土地利用数据(LU),沙尘监测数据(TSP),卫星 AVHRR时间序列 LST/Albedo数据,采用贝叶斯网络模型进行了知识描述和信息推理预测实验,取得了较好的效果。Abstract: Bayesian network is a new inference and express method of uncertain knowledge. It is proposed an inference and express technique for remote sensing imagery data which has complexity and uncertainty based on Bayesian Network Model(BNM). In the paper, the LU data, TSP and LST/Albedo data of AVHR.R time-sequence imagery which get from the project of China-Japan Asian dust storm in 2002 are used to analyze the dust storm and at the same time BNM is used to describe the knowledge and information inference. The satisfied results are given in the paper with the method.
