摘要
基于无人机搭载多镜头相机快速获取地物地貌的高精度多视影像,根据影像上地物的纹理信息和几何信息生成倾斜三维模型,已成为实景三维领域内成熟的生产手段。针对带状场景下倾斜摄影实景三维模型生产和精度控制,依然缺乏相关规范和作业指引。以某高速公路选线项目中三维模型生产为例,介绍带状场景下倾斜摄影实景三维模型生产技术流程,探讨不同像控点布设方案对空三和模型精度的影响,并对成果质量进行检测和评价。
Based on the multi-lens camera mounted on the UAV to quickly obtain high-precision multi-view images of ground features and landforms,the inclined three-dimensional model is generated according to the texture information and geometric information of the ground objects on the image,which has become a mature production method in the field of three-dimensional reality.For the production and precision control of the 3D model of the oblique photography real scene in the strip scene,there is still a lack of relevant specifications and operation guidelines.Taking the production of 3D models in a highway route selection project as an example,this paper introduces the production technology process of 3D models for oblique photography in strip scenes,discusses the influence of different image control point layout schemes on the accuracy of air 3D and models,and tests the quality of the results.
