摘要

Aerial photogrammetry is an efficient and accurate image mapping technology that provides reliable data support for the rapid three-dimensional reconstruction of ground targets. To align with the developmental trends of virtual testing, this study employs aerial photogrammetry to conduct three-dimensional real-scene modeling for the virtual proving ground. Through field operations such as site surveys, placement of image control points, flight path design, and image data acquisition, as well as critical data production stages including image preprocessing, aerial triangulation processing, model modification, and accuracy analysis, the complete workflow for three-dimensional virtual proving ground modeling is achieved. The research results demonstrate that the three-dimensional model constructed using aerial photogrammetry technology is realistic and rich in texture, with high positional and attribute accuracy. Additionally, the development of the three-dimensional virtual proving ground provides scenario-based foundation support for the dynamic construction of digital twin models in full life cycle aviation test.
