TV camera is a technology that applies electronic technology to convert, record, transmit and reproduce the activities of scenery or people, and it is also an important way and means to record sound and moving images. UAV TV camera system is composed of five major parts, such as TV image ingestion (also including infrared image ingestion), recording, transmission, reception and reproduction, and control, which is used to complete the continuous reconnaissance of a certain area on the ground by the UAV, as well as the rapid positioning of the ground target and other functions. TV camera is one of the important sensors for UAV to take images, as early as 1925, the British successfully tested the mechanical scanning TV, at the same time, the Americans also invented the electronic scanning system and photoelectric camera tubes. around 1930, the British, Russian and other countries started the mechanical black and white TV broadcasting, and after that, in 1951, the U.S. test-broadcasted a kind of colour TV signals which are incompatible with black and white TVs; and in 1953, the U.S. adopted the mechanical black and white TV broadcasting system. In 1953, the United States adopted the NTSC colour television system to achieve compatibility with the black-and-white television system. It should be said that from the 1950s onwards, along with the TV reconnaissance technology began to be gradually applied to the field of military intelligence acquisition, the aviation and aerospace reconnaissance technology has also been developed rapidly, and the accuracy and timeliness of its intelligence acquisition has also been greatly improved.
