Elevated photography can also produce bird's-eye images closely resembling aerial photography (despite not actually being aerial shots) when telephotoing from a high vantage structures, suspended on cables (e.g. Skycam) or on top of very tall poles that are either handheld (e.g. monopods and selfie sticks), fixed firmly to ground (e.g. surveillance cameras and crane shots) or mounted above vehicles.
[6] The same year, Cecil Shadbolt devised a method of taking photographs from the basket of a gas balloon, including shots looking vertically downwards.
[11] The first use of a motion picture camera mounted to a heavier-than-air aircraft took place on April 24, 1909, over Rome in the 3:28 silent film short, Wilbur Wright und seine Flugmaschine.
The use of aerial photography rapidly matured during the war, as reconnaissance aircraft were equipped with cameras to record enemy movements and defenses.
At the start of the conflict, the usefulness of aerial photography was not fully appreciated, with reconnaissance being accomplished with map sketching from the air.
Frederick Charles Victor Laws started aerial photography experiments in 1912 with No.1 Squadron of the Royal Flying Corps (later No.
The Royal Flying Corps recon pilots began to use cameras for recording their observations in 1914 and by the Battle of Neuve Chapelle in 1915, the entire system of German trenches was being photographed.
Moore-Brabazon also pioneered the incorporation of stereoscopic techniques into aerial photography, allowing the height of objects on the landscape to be discerned by comparing photographs taken at different angles.
1 Squadron AFC to photograph a 624 square miles (1,620 km2) area in Palestine as an aid to correcting and improving maps of the Turkish front.
Lieutenants Leonard Taplin, Allan Runciman Brown, H. L. Fraser, Edward Patrick Kenny, and L. W. Rogers photographed a block of land stretching from the Turkish front lines 32 miles (51 km) deep into their rear areas.
Using Royal Aircraft Factory BE.12 and Martinsyde airplanes, they not only overcame enemy air attacks, but also had to contend with 65 mph (105 km/h) winds, antiaircraft fire, and malfunctioning equipment to complete their task.
[15] The first commercial aerial photography company in the UK was Aerofilms Ltd, founded by World War I veterans Francis Wills and Claude Graham White in 1919.
Operations began from the Stag Lane Aerodrome at Edgware, using the aircraft of the London Flying School.
[17] In 1920, the Australian Milton Kent started using a half-plate oblique aero camera purchased from Carl Zeiss AG in his aerial photographic business.
[20] A year later, Fairchild introduced a better high altitude camera with nine-lens in one unit that could take a photo of 600 square miles with each exposure from 30,000 feet.
[21] In 1939 Sidney Cotton and Flying Officer Maurice Longbottom of the RAF were among the first to suggest that airborne reconnaissance may be a task better suited to fast, small aircraft which would use their speed and high service ceiling to avoid detection and interception.
Although this seems obvious now, with modern reconnaissance tasks performed by fast, high flying aircraft, at the time it was radical thinking.
[citation needed] They proposed the use of Spitfires with their armament and radios removed and replaced with extra fuel and cameras.
Together with other members of the 1 PRU, he pioneered the techniques of high-altitude, high-speed stereoscopic photography that were instrumental in revealing the locations of many crucial military and intelligence targets.
[24] Oblique aerial photography is used for movie production, environmental studies,[27] power line inspection,[28] surveillance, construction progress, commercial advertising, conveyancing, and artistic projects.
An example of how aerial photography is used in the field of archaeology is the mapping project done at the site Angkor Borei in Cambodia from 1995 to 1996.
[31] The ban has been lifted and commercial aerial photography using drones of UAS is regulated under the FAA Reauthorization Act of 2018.
Examples would include the inspection of transformers atop power transmission lines and slow, low-level flight over agricultural fields, both of which can be accomplished by a large-scale radio-controlled helicopter.
[36] In addition to gyroscopically stabilized footage, the use of RC copters as reliable aerial photography tools increased with the integration of FPV (first-person-view) technology.
"[44] Because anything capable of being viewed from a public space is considered outside the realm of privacy in the United States, aerial photography may legally document features and occurrences on private property.
[45] The FAA can pursue enforcement action against persons operating model aircraft who endanger the safety of the national airspace system.
Effective April 14, 2017, all UAS flights within 400 feet of the lateral boundaries of U.S. military installations are prohibited unless a special permit is secured from the base and/or the FAA.
Pictures that will be used in photogrammetry are traditionally taken with special large format cameras with calibrated and documented geometric properties.
The input video is captured by low flying aerial platforms and typically consists of strong parallax from non-ground-plane structures.
The integration of digital video, global positioning systems (GPS) and automated image processing will improve the accuracy and cost-effectiveness of data collection and reduction.
