Missions: Photogrammetry
About photogrammetry
According to the American Society for Photogrammetry and Remote Sensing (ASPRS), photogrammetry is
the science and technology of obtaining reliable information about physical objects and the environment
through the process of recording, measuring and interpreting photographic images.
The ASPRS was created in 1934, but the field of photogrammetry has since greatly benefited of the
emergence of flying cameras such as Parrot drones. One of the leaders of the field is PIX4D, which became a
Parrot Group company in 2012.
ANAFI Ai and FreeFlight 7 therefore embark PIX4D technologies which enable existing PIX4D users to
seamlessly link their drone to their PIX4D account. New users can use ANAFI Ai to discover PIX4D
photogrammetry services, through three offered mapping missions.
There are four types of photogrammetry mapping missions: Grid, Double grid, Orbit and
1-Click.
This section describes the specificities of each mission, and the way to program them.
To launch a photogrammetry flight, select “Photogrammetry” through the Missions selection menu
of FreeFlight 7.
Grid
Simple grid photogrammetry flights are useful to create 2D maps. Simple grids can be precisely adapted to
any shape, to match the borders of a field or a coastline, for example. Follow these steps to program and
launch a simple grid mapping flight.
