基于无人机倾斜摄影的高层建筑变形测量方法

Research on Modern Communication System Deformation Measurement Method of High-rise Buildings Based on UAV Oblique Photography

高层建筑通常指高于24 m而未超过100 m的建筑,高层建筑更容易发生变形,而传统的地面监测设备使用范围受限,难以测出高层建筑较高区域的变形,因此提出基于无人机倾斜摄影的高层建筑变形测量方法。在计算无人机航线方案参数后,规划倾斜摄影参数。对摄影图像处理后,提取特征点,利用PMVS算法建立点云。以设计图纸数据为参考,在三维建模软件中比对测量数据建模和设计建模,从而得到建筑变形量。在实测研究中,所提出的方法测量误差较小,测量时间至少缩短15.07%,测量结果稳定可靠。

High rise buildings usually refer to the buildings that are higher than 24m but less than 100m.High rise buildings are more prone to deformation.However,the use range of traditional ground monitoring equipment is limited,and it is difficult to measure the deformation in the higher area of high rise buildings.Therefore,a deformation measurement method for high rise buildings based on UAV tilt photography is proposed.After calculating the route scheme parameters of UAV,plan the tilt photography parameters.After the photographic image is processed,the feature points are extracted and the point cloud is established using the PMVS algorithm.With the design drawing data as reference,compare the measurement data modeling and design modeling in the 3D modeling software to obtain the building deformation.In the practical study,the measurement error of the proposed method is small,the measurement time is shortened by at least 15.07%,and the measurement results are stable and reliable.
