Aerial video is an emerging form of data acquisition Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acro ...
for scene understanding and object tracking. The video is captured by low flying aerial platforms that integrate Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite sy ...
s (GPS) and automated image processing to improve the accuracy and cost-effectiveness of data collection and reduction. Recorders can incorporate in-flight voice records from the cockpit intercom system. The addition of audio narration is an extremely valuable tool for documentation and communication. GPS data is incorporated with a text-captioning device on each video frame
In filmmaking, video production, animation, and related fields, a frame is one of the many '' still images'' which compose the complete '' moving picture''. The term is derived from the historical development of film stock, in which the sequenti ...
. Helicopter platforms enable "low and slow" flights, acquiring a continuous visual record without motion blur.
Innovations in remote sensing
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Eart ...
cameras have allowed the identification of objects that could not have been previously identified. Pipeline and power corridors and their infrastructure can be documented with digital media recording. Video Mapping System is an example of how this technology is used today.
Since the 1980s, aerial videography has seen increased use in applications where its advantages over traditional photography (lower cost and immediate availability of data) outweigh its disadvantages (poorer spatial resolution
In physics and geosciences, the term spatial resolution refers to distance between independent measurements, or the physical dimension that represents a pixel of the image. While in some instruments, like cameras and telescopes, spatial resolut ...
and difficulty of analysis due to lack of stereo imaging) (Mausel et al. 1992; Meisner 1986). King (1995) provides a comprehensive review of the evolution of video sensors and their applications, many of which focused on:
# The measurement of transient phenomena such as wildlife populations (Sidle and Ziewits 1990; Strong and Cowardin 1995) and pest infestations (Everitt et al. 1994);
# Mapping of dynamic land features such as wetland plant communities (Jennings et al. 1992) and coastal land forms (Eleveld et al. 2000); # Land cover mapping in remote areas with limited existing aerial photography and poor infrastructure
(Marshet al. 1994; Slaymaker and Hannah 1997).
