What Are the Advantages of Digital Aerial Photogrammetry System?

Jun 12, 2023

With the continuous development of digital technology, aerial remote sensing data acquisition has entered the all-digital era. Compared with traditional film photography, the digital aerial photogrammetry system has the advantages of lower requirements on weather standards, more diversified products, and higher ground resolution. The airborne POS technology of the aerial photogrammetry system uses the integrated global positioning system (GPS) and inertial measurement unit (IMU) to simultaneously obtain the 6 outer orientation elements of the center point of the high-precision photo, which changes the internal process and reduces the external The workload of the industry greatly shortens the time from obtaining aeronautical data in the field to generating 4D products, and improves work efficiency.

In recent years, Feiyan Remote Sensing has implemented a number of aerial photography data processing projects through large-format digital aerial photography, tilt aerial photography, and lidar digital aerial photography, such as the Fujian coastline + Fujian Fuzhou New District digital orthophoto data processing project, the Yellow River Data processing project of digital elevation model of river channel. Based on aerial photogrammetry technology, the work of field data acquisition is completed efficiently; when data processing, based on the shooting time and location, the accurate calculation of image sunlight reflection compensation model is used to solve the problem of The problem of uneven color of images at different times and locations.
