Abstract

Abstract: 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.

Key words: tilt photogrammetry, near-view photogrammetry, air-ground integration, real-world 3D, high definition
