摘 要:传统手工方式建模消耗时间长、人力投入大、生产周期长,但建出模型的精细程度较高,模型数据量可控。相对于手工方式建模,无人机三维建模的优势在于耗时较短、人力投入较小,但模型精细程度相对较低,且模型数据量较大,在某些时候不能满足使用者的需求。文中将这两种建模方式相结合,提出基于无人机倾斜摄影的三维模型手工修正方法,在提高模型精细程度的同时,又可以缩减模型数据量,从而提高了模型的普适性。

Abstract: Traditional manual modeling takes a long time, requires a large amount of manpower, and requires a long production cycle. However, the precision of the model is high, and the model data volume is controllable. Compared with manual modeling, UAV 3D modeling has the advantages of shorter time consumption and less manpower investment, but the model is relatively low in refinement and has a large amount of model data, which can not meet the needs of users in some cases. Combining these two modeling methods, this paper proposes a manual correction method of 3D model based on UAV tilt photography, which can improve the precision of the model and reduce the amount of model data, thus improving the universality of the model.
Keywords: UAV; 3D modeling; manual modeling; model correction
