Research status of vertical photogrammetry

Photogrammetry technology, 3D modeling and visualization.

1. Photogrammetry technology: With the development of digital aerial photography and lidar technology, the traditional vertical photogrammetry has changed from film photography to digital photography, and high-precision three-dimensional measurement has been realized by combining ground control points and navigation and positioning systems.

2. 3D modeling and visualization: Through multi-angle vertical photography combined with stereo registration and 3D reconstruction algorithm, fine 3D modeling and realistic rendering of the scene can be realized, which provides better tools and methods for virtual reality, game development and urban planning decision-making.
