空地一体化快速实景建模技术探究

智慧测绘地理信息服务的发展对实景三维模型的真实感、实用性和精度提出了更高的要求，如何快速生产高精细、高精度实景三维模型成为测绘地理信息热点研究方向之一。本文结合空中倾斜摄影测量建模的特点，探索了基于空中倾斜摄影和地面近景摄影测量快速进行一体化建模的技术，从近景传感器设计、数据采集、数据处理三方面探究了一套高效的空地一体化建模工艺，并完成了试验区的空地一体化实景模型制作，取得了较好的效果。该项研究弥补了空中倾斜摄影建模在近地面模型变形甚至缺失的不足，使基于倾斜摄影测量进行实景建模进入了一个新的阶段。

Research on the rapid practical modeling technology of ground-to-air integration

The development of intelligent surveying and mapping geographic information service puts forward higher requirements on the realism, practicability and precision of the real-life 3D model. How to quickly produce high-definition and high-precision real-world 3D models has become one of the research directions of surveying and mapping geographic information hotspots. With the characteristics of current aerial tilt photogrammetry modeling, this paper explores the technology of integrated modeling based on aerial tilt photography and ground close-range photogrammetry. It studies a set of ground and air integration from three aspects: close-range sensor design, data acquisition and data processing. The modeling process and the ground-space integrated real-world model of the experimental area is completed, and good results are obtained. This research makes up for the lack of deformation or even the lack of aerial tilt photography modeling in the near-surface model, and makes the real-time modeling based on tilt photogrammetry into a new stage.
