摘要
倾斜影像技术是当前测绘领域的一项高新技术,突破了传统航摄测量技术的局限性。相对于传统的垂直航空摄影,倾斜影像技术具备有效地获取地物侧面纹理、可对同一地区进行多视角重复观测,在保证三维模型定位精度高、纹理细节好的同时,实现了获取城市实景三维模型的高度自动化,因而在三维城市建模中得到广泛的应用。本文介绍了一种基于倾斜影像技术的三维城市建模影像筛选方法,并通过实验,验证了该方法具有较高的可行性。
Tilt image technology is a new and high technology in the field of surveying and mapping,which breaks through the limitation of the traditional aerial photography measurement technology.Compared with traditional vertical aerial photography,tilt image technology has the ability to effectively obtain the side texture of the object,and can repeatedly observe the same area from multiple perspectives.While ensuring the high positioning accuracy and texture details of the three-dimensional model,It has been widely used in 3D urban modeling because of its high automation.In this paper,a new method based on tilt image technology for image screening of 3D urban modeling is introduced.
