Tilt Aerial photography capture aerial images at an angle, so that ground objects within a certain area can be captured from four directions. The high resolution oblique photography can be used for 3D model building, which can be applied in urban planning, attractions sightseeing, security and defense, emergency management, and BIM construction.
Pictures below shows a set of nadir and oblique images taken in 2018 for a 5cm-resolution 3D city model.

Aerial photogrammetry is generally low altitude flight, which is easy to operate in airspace and will not be affected by extreme weather. At the same time, it is not limited to the needs of take-off and landing sites. It only needs to select a relatively flat site for take-off and landin...
As we all know, aerial photogrammetry technology is playing an increasingly important role in urban planning and construction. Moreover, compared with the traditional topographic survey technology, aerial photogrammetry technology has the advantages of small volume, light weight, ra...
After the LiDAR data is obtained, the data can be post-processed only after data preprocessing. After the data preprocessing, there is a data checking software to conduct a preliminary check on the data results. The general data format check has the follo
