摘　　要：从城市超高层建筑物变形监测实施困难、建筑基线分量误差较大、监测成果可靠性较低等问题出发,以北斗卫星导航系统为基础,获取超高层建筑物卫星图像数据,利用小波阈值去噪算法对图像数据中的噪声进行去噪处理,然后提取建筑物形变监测面的位移距离和位移方向,解算超高层建筑物变形特征。为分析监测方法的可靠性,设计测试实验,从监测点基线分量误差和探测精度方面对北斗导航系统监测成果进行分析研究,并与其他监测方法进行对比,综合验证了北斗导航系统在超高层建筑物变形监测中的可靠性,为城市超高层建筑物安全监测提供了可靠有效的技术方案。Based on the difficulties in implementing deformation monitoring of urban super high-rise buildings,large errors of building baseline components and low reliability of monitoring results,this paper obtains satellite image data of super high-rise buildings based on the Beidou navigation satellite system and uses wavelet threshold denoising algorithm to de-noise the noise in the image data.Then the displacement distance and displacement direction of building deformation monitoring surface are extracted to solve the deformation characteristics of super high-rise buildings.In order to analyze the reliability of the monitoring method,a test experiment is designed to analyze and study the monitoring results of the Beidou navigation satellite system from the aspects of baseline component error and detection accuracy of the monitoring points,and compared with other monitoring methods to comprehensively verify the reliability of the Beidou navigation satellite system in deformation monitoring of super high-rise buildings.It provides a reliable and effective technical scheme for the safety monitoring of urban super high-rise buildings.
