摘　　要：利用大疆M300RTK无人机搭载禅思P1云台获取超高分辨率的数据影像,精准还原地表和物体精细纹理、结构和特征优势,为实现高层建筑外墙饰面层缺陷检测提供技术支撑。为获得高精度的三维实景模型,首先使用WayPoint Master软件对被测建筑周边设定仿地环绕飞行航线,采用大疆智图软件对影像数据构建三维粗模,然后在粗模中提取被测建筑KMZ信息,建立精细化航线,利用无人机和贴近摄影测量技术,最终可生成分辨率为0.63 cm的高精度三维模型。实践证明,贴近摄影测量技术能够实现对建筑外墙饰面层缺陷面积、裂缝等数据的准确测量。Using the DJI M300RTK drone equipped with the Zenmuse P1 gimbal,ultra-high-resolution images are obtained to accurately restore the fine texture,structure,and features of the ground and objects,so as to provide technical support for the defect detection of the exterior decorative layer of high-rise buildings.To obtain the high-precision 3D real-scene model,the WayPoint Master software is used to set up a pseudo-ground orbit flight route around the measured building,and the DJI Smart software is used to construct a 3D rough model based on the image data.Then,the KMZ information of the measured building is extracted from the rough model,and a refined flight route is established.Finally,a 3D model with a resolution of 0.63 cm can be generated by using the drone and close-range photogrammetry.Practice has proved that close-range photogrammetry can accurately measure the defect areas and cracks on the exterior decorative layer of buildings.
