摘要
针对消费型无人机倾斜摄影测量技术获取河道大区域复杂地形多视影像存在一定局限性,导致河道实景三维模型存在空洞与缺失问题,提出消费型无人机在河道精细化三维构建中的应用方法。通过不同航拍方式获取目标区域详细的多视影像数据,结合多种成熟软件进行河道区域精细化建模,有效地解决三维模型存在空洞与缺失问题,获取了高精度、精细化实景三维模型,为大区域、复杂情况的河道精细化建模提供一种思路。
There are some limitations in the multi-view images of large-scale complex terrain obtained by the tilt photogrammetry technology of consumer UAV,which leads to the problems of voids and missing in the real scene 3D model of the river channels.The application method of consumer UAV in the refined 3D construction of the river channels is proposed.The detailed multi-view image data of the target area is obtained by different aerial photography methods,and the river area refined modeling is carried out by combining a variety of mature software,which effectively solves the problem that voids and missing are in the three-dimensional models,and obtains a high-accurate and refined real scene three-dimensional model,providing an idea for the refined modeling of the river in large areas and complex situations.
