Design of a Monitoring System for Key Areas of Non-Uniform Surface in Satellite Remote Sensing Observation Based on Wireless Sensor Networks
The monitoring data of key areas of uneven surface observed by satellite remote sensing are usually complex and uncer-tain.It is difficult to accurately determine the key monitoring areas and obtain useful information,resulting in limited monitoring range and large errors in monitoring results.Therefore,in order to provide data support for the treatment of non-uniform surface,wireless sensor network is used to optimize the design of satellite remote sensing observation of non-uniform surface monitoring sys-tem in key areas.Add the satellite remote sensing observation image sensor,adjust the wireless sensor network module,refit the mo-nitoring data processor,and use the adjusted system circuit to connect the hardware components to complete the optimization of the hardware system.With the support of hardware and database,wireless sensor networks are constructed from the aspects of topology and transmission protocol.Realize the deep integration of high-altitude remote sensing and wireless sensor networks,and use wireless sensor networks to collect satellite remote sensing images of the earth's surface,obtain surface information,and expand the monito-ring range;Through filtering,geometric correction and other steps,the preprocessing of the initial image is realized,and the image features are extracted.According to the matching results of the feature images,the key areas of uneven surface are determined,and the monitoring of the key areas of uneven surface observed by satellite remote sensing is completed combined with the indicators such as the inclination angle of the surface and the degree of uneven surface.The experimental test shows that compared with the tradition-al monitoring system,the monitoring errors of the optimized design system output surface tilt angle and surface deformation are re-duced by 0.28° and 0.73 m3,respectively,and the monitoring range of the system is significantly expanded.
