Abstract
Unmanned Aerial Vehicles (UAV) tilt photogrammetry technology can quickly acquire image data in a short time. This technology has been widely used in all walks of life with the rapid development in recent years especially in the rapid acquisition of high-resolution remote sensing images, because of its advantages of high efficiency, reliability, low cost and high precision. Fully using the UAV tilt photogrammetry technology, the construction image progress can be observed by stages, and the construction site can be reasonably and optimally arranged through three-dimensional modeling to create a civilized, safe and tidy construction environment.
