FPV means First Person View, and it used in drone racing.
Drone Racing is a Sport where participants control a drone equipped with cameras while wearing a Head-mounted display showing the live stream camera feed from the drones. Similar to full size Air racing, the goal is to complete a set course as quickly as possible. Drone racing began in Germany in 2011 with a number of amateur pilots getting together for semi-organized races in Karlsruhe.
We use this technology to get fast and dynamic camera movements.
