Abstract
Abstract. Three-line array stereo aerial survey camera is a typical mapping equipment of aerial photogrammetry. As one of the airborne equipment, it can quickly obtain a large range of basic geographic information with high precision. At present, typical three-line array stereoscopic aerial survey cameras, such as Leica ADS40 and 80, have the disadvantages of small field of view and low resolution, which makes it difficult to meet the demand of large-scale topographic mapping for economic construction. For the urgent need of domestic three linear array aerial mapping camera in our project, we developed the AMS-3000 camera system. Camera features include a large field of view, high resolution, low distortion and high environmental adaptability. The AMS-3000 system has reached the international advanced level on both software and hardware aspects.
Highlights
Three-line array stereo airborne mapping camera can quickly acquire a wide range of high-resolution basic geographic information, which plays a significant supporting role in digital city construction, earthquake relief, resource navigation, environmental protection, homeland security and other works
The airborne digital camera first appeared in the international society for photogrammetry and remote sensing (ISPRS) conference in 2000 (Eckardt et al, 2000)
It is very necessary to develop three-line array stereo airborne mapping cameras with high resolution and large field of view to meet the needs of mapping of large scales (Lu et al, 2016)
Summary
Three-line array stereo airborne mapping camera can quickly acquire a wide range of high-resolution basic geographic information, which plays a significant supporting role in digital city construction, earthquake relief, resource navigation, environmental protection, homeland security and other works. Digital aerial mapping cameras are mainly divided into two categories, one mainly using area-array detectors, the other mainly using linear array detectors (Yao et al, 2018). Imported cameras are expensive and still have some shortcomings, including difficulties in mapping of small and medium-sized scales, low resolution, small working width and low operating efficiency These aerial mapping cameras have solved part of the demand of the market to some extent, but they are still far from meeting the demand of China's rapid economic construction for a large amount of aerial remote sensing surveying and mapping geographic information. It is very necessary to develop three-line array stereo airborne mapping cameras with high resolution and large field of view to meet the needs of mapping of large scales (Lu et al, 2016). The key technology of AMS-3000 is significantly superior to the most advanced ADS40/80 in the world, and it has the high performance to support the economic construction of China
