Advantages of A3

A3 aerial camera is famous for its superior data acquisition ability. The camera adopts a 300mm long focal length lens, which makes the camera have super data acquisition ability and image resolution. Taking the data with ground resolution of 0.3m as an example, the scanning width reaches 25,957m, and the orthophoto image of 7 1.2 1 km2 can be obtained every hour.

An oversized image

A3 adopts the step-by-step imaging method, and can obtain an ultra-wide image with a maximum of about 62,000 * 8,000 (496 million) pixels. Taking the ground resolution of 0.3m as an example, the coverage width of A3 is 25,957m. Compared with other mainstream devices, A3 has wider image frames and higher data acquisition efficiency.

A variety of products can be obtained in one flight.

After one flight, A3 system can obtain multiple data products at the same time without additional flight and data processing:

High-resolution and high-quality digital images;

Automatic one-time production of high-precision DSM products without additional workload;

High-precision DEM products;

High-precision DOM products (up to 1: 500 basic scale mapping);

Ultra-large format tilt photogrammetry products (used to establish stereo image pairs, three-dimensional production, etc. )

High precision products

Because of the special imaging mode of A3 system (frame+scan), highly overlapping images can be obtained, and the same point has image response in dozens of images. Because the same spatial point can be solved by dozens of redundant observation values (* * * linear equation), the spatial position of this point can be obtained by accurate inversion, that is, high-precision product production can be completed.
