2.Surveying and mapping
UAV surveying and mapping the terrain environment is a new technology used in the field of remote sensing for terrain surveying and mapping, and it is also an important step in 3D modeling in urban construction. The use of drones can reduce the cost of modeling, and the drone has a fast response speed, small body, simple structure, easy to carry, no matter what kind of environment, even the messy outdoor environment has good adaptability, not only It can complete the aerial photography mission of traditional aircraft, and for some areas covered by traditional techniques, drones can also smoothly carry out aerial surveying and mapping, and then perform 3D modeling and analysis on this.
