Aerial photography is to take aerial photography of the target by manned or unmanned aerial vehicles, and convert these aerial images into data. Through software, the recent status of the target can be analyzed, and timely analysis and timely prediction of the future can be made. Aerial photography includes orthographic (DOM) and tilt aerial photography (TDOM), and different aerial photography methods are provided for different services.
UAVs are easy to operate, flexible in maneuvering, low in cost, and not restricted by harsh environments and complex terrains. In particular, compound-wing UAVs with outstanding advantages such as long flight time and fast speed can quickly complete large-area data collection, and are especially suitable for oblique photogrammetry. At the same time, tilt photography cameras are developing towards lightweight and miniaturization. The two have jointly promoted the innovation of oblique photography technology and become a powerful assistant for real-world 3D construction.
