星敏感器在海上遥感测绘中的计量方法

Measurement method of star sensor in marine remote sensing surveying and mapping

传统的海上遥感测绘计量方法会受外界因素的影响,无法精确的计量测绘数据,为了解决这个问题,提出基于星敏感器的海上遥感测绘计量方法。利用星敏感器,提取海上遥感测绘数据,再利用极大似然法,处理海上遥感测绘数据,在此基础上,应用海上遥感测绘计量模型,得出精准的计量测绘数据。考虑到重力加速度的问题,需引入测速传感器,对速度进行补偿处理。由此,完成基于星敏感器的海上遥感测绘计量方法的设计。最后,通过仿真实验,对比2种方法的精准度,实验结果表明,所以方法相比传统的海上遥感测绘计量方法精准度更高。

The traditional measurement methods of marine remote sensing surveying and mapping will be affected by external factors and can not accurately measure the surveying and mapping data.To solve this problem,a measurement method of marine remote sensing surveying and mapping based on star sensor is proposed.The satellite sensor is used to extract the data of remote sensing surveying and mapping at sea,and then the maximum likelihood method is used to process the data of remote sensing surveying and mapping at sea.On this basis,the precise measurement and mapping data are obtained by applying the measurement model of remote sensing surveying and mapping at sea.Considering the problem of gravity acceleration,the velocity sensor should be introduced to compensate the velocity.Thus,the design of measurement method for remote sensing surveying and mapping at sea based on star sensor is completed.Finally,through simulation experiments,the accuracy of the two methods is compared.The experimental results show that the accuracy of the method is higher than that of the traditional marine remote sensing surveying and mapping measurement method.
