Foundation pit excavation method based on unmanned aerial vehicle image
The invention relates to the field of building construction, and particularly discloses a foundation pit excavation method based on unmanned aerial vehicle images, which comprises the following steps of: arranging at least three reference columns easy to distinguish around a foundation pit, respectively carrying civil-level non-measurement cameras by utilizing two unmanned aerial vehicles, and acquiring data of the foundation pit and the reference columns by utilizing an oblique photography technology; and then modeling the foundation pit, and correcting the distortion of the image acquired by the non-measurement camera by utilizing the deformation calculation of the two groups of data and the reference column in the modeling process, so as to restore the measurement model more accurately. According to the scheme, a civil-level non-measurement camera can be utilized, the use cost is low, and meanwhile the problem that civil-level products are not high in precision is solved.
本发明涉及建筑施工领域，具体公开了一种基于无人机图像的基坑开挖方法，包括以下步骤，在基坑四周设置至少三根易于区分的基准柱，利用两台无人机分别搭载民用级别的非量测相机，利用斜摄影技术采集基坑和基准柱的数据，然后对基坑进行建模，在建模过程中利用通过两组数据和基准柱的变形量计算、矫正所述非量测相机采集画面的畸变，更为准确地还原测量模型。本方案可以利用民用级别的非量测摄像机，使用成本低，同时解决了民用级别产品精度不高的问题。
