Abstract

Abstract: For mega cities with large areas, city level, and multiple sensitive areas, taking into account factors such as safety, efficiency, and airspace, a helicopter flight platform equipped with multi lens tilt cameras is adopted, and oblique photogrammetry technology is used to timely and effectively obtain on-site 3D real scenes. This project is based on the application of helicopter oblique photogrammetry technology in mega cities, which can quickly and efficiently obtain multi view high-resolution image data of the measured area. By using image data for 3D modeling, measurable 3D models can be constructed to meet the requirements of refined governance in mega cities.

Key words: helicopter, oblique photogrammetry, 3D modeling, measurable
