基于无人机倾斜摄影测量的校园实景三维建模

The 3D Modeling of Campus Real Scene Based on UAV Tilt Photogrammetry

通过无人机倾斜摄影测量与BIM(建筑信息模型)技术结合构建校园三维实景模型,并对模型中建筑物内部进行精修、外部周围进行绿化。最后,对测区所设置的控制点和特征点进行了检测,计算了各点位置误差和标高误差,所建立的模型符合地形测绘的精度要求。

This paper mainly expounds the construction of a three-dimensional real scene model of campus through the combination of UAV tilt photogrammetry and BIM Technology,and refines the interior of the building in the model,and afforests the exterior surrounding.Finally,the control points and feature points set up in the survey area are detected and the position error and elevation error of each point are calculated respectively,and the established model meets the accuracy requirements of topographic mapping.
