What is Aerial Filming?
Aerial videos are emerging ‘Spatial Multimedia’, which is the combination of photographs, motion videos, audios, panoramas, and other data. Aerial videos are generally used to understand scenes and track objects. The input is captured with the help of low flying aerial platforms usually consisting of strong parallax from a non-ground plane structure. With the help of global positioning system(GPS) and automated image processing improves the accuracy and cost-effectiveness.
How to shoot Aerial videos?
Stabilized aerial video can be made with the gimbals. A gimbal allows the rotation of an object around an axis.
Platforms used for aerial videography are usually drones, helicopters, kites, parachutes, etc, some of them are remotely controlled like drones while the others manually operated like helicopters. GoPro Hero3 is the standard camera used for videography.
Origin of Aerial Filming
Aerial filming was first practiced by a French photographer and balloonist Gaspard Felix Tournachon in the year 1858. It was popularized during the first world war to keep a track on enemy movement and defenses. The reconnaissance aircraft were equipped with cameras.
Even during the second world war, small aircraft were equipped with cameras to monitor the enemy movement and survey the areas. Today this is used for real estate surveys, movies, traveling, shooting exotic locations, special occasions like weddings.
Different types of Aerial Filming
1. Obliques: taken from a particular angle, if it is from a low angle it is called as low oblique and if it is from a higher angle it is called as high or steep oblique.
2. Vertical: they are taken straight down.
3. Combinations: photos are often combined together, like panorama where photos are stitched together, Pictometry where 5 cameras one at vertical and other four at oblique are used.
4. Orthogonal: the videos are taken from aircraft mapping pipelines, crop line and other fields of interest.
