What are the pronouns of satellite aerial photography?

Aerial photography is a hot topic at present, and a large part of aerial photography is the skill of shooting and operation. Aerial photography, also known as aerial photography or aerial photography, refers to shooting the earth's landform from the air to get a top view. This is an aerial photograph.

The aerial camera can be controlled by the photographer, and can also be automatically photographed or remotely controlled. The platforms used in aerial photography include airplane models, airplanes, helicopters, hot air balloons, small spacecraft, rockets, kites and parachutes. In order to make aerial photos stable, advanced photographic equipment such as Spacecam is sometimes used, and the stable function of three-axis gyroscope can be used to provide high-quality stable images even under long focal length lenses. Aerial photography can clearly show the geographical form, so it is not only a part of photography art, but also used in military affairs, traffic construction, water conservancy projects, ecological research, urban planning and so on.

Let me first introduce the basic terms of aerial photography:

1, AF: autofocus: active focus. At present, all home cameras have this function, and the focusing action is ended by infrared ranging. A group of infrared emitters at the lower part of the lens, when the lens is aimed at the policy, infrared rays also sense the interval between the lens and the policy, driving the focusing mechanism to focus together. Please paste the glass when taking pictures in front of the glass window. If the situation does not allow, please switch to manual focusing.

2. UAV aerial photography: UAV aerial photography. The aerial photography of UAV is based on UAV, equipped with remote sensing equipment, high-resolution CCD digital camera, light optical camera, infrared scanner, laser scanner, magnetic detector and so on. Get information, and use computer to process picture information, integrating new application skills such as aerial photography, remote control, telemetry, microwave transmission of video impression, and computer impression information processing.

3. Down shutter: shutter. A device used to control exposure time. Shutters can usually be divided into curtain blinds, lens blinds and steel blinds. At the same time, curtain blinds can be divided into vertical curtain blinds and horizontal curtain blinds. Steel shutter can reach higher speed (the highest shutter speed can reach112000 seconds or more at present).

4. Aerial remote sensing: aerial remote sensing. Aerial remote sensing is mainly based on sensors installed on drones (to get accurate data from the air overlooking the ground). With the improvement of skills, hyperspectral remote sensing and quantitative remote sensing are changing the qualitative methods of visual interpretation.

5. Aerial photography: aerial photography. Also known as revealing the common sense of aerial photography, it refers to the skill of shooting ground scenes with aerial cameras on airplanes or other aviation aircraft.

6. Panoramic photography: new knowledge of panoramic aerial photography. Panoramic aerial photography is first of all the direct impression of aerial photography of remote sensing drones and the panoramic impression made by panoramic manufacturing software in the later period, which is called "basic knowledge training of panoramic aerial photography".

7, aerial camera: aerial photography encyclopedia Yuntai. An aerial platform is a device that connects a camera or video camera with a tripod. Pan-tilt is an instrument that can accurately determine the orientation of moving objects. It is a kind of aerial photography knowledge introduction equipment widely used in modern aviation, navigation, aerospace and national defense industries.

8.AWB (automatic white balance): active white balance. The white balance of the camera is mainly the basis for CCD to correct colors under different light sources, which is usually set in the active direction. Some models can also be adjusted manually, such as sunshine, sunset, cloudy days and light bulbs. Advocacy is always best set to be completely active. If you feel yellow when taking pictures indoors, you can switch to the light bulb orientation.

9. Aerial mapping: aerial mapping. As a surveying and mapping method, the aircraft in the atmosphere is used as the carrier to survey topography, and its primary concern is the orientation relationship of ground objects, and the geodetic coordinates of the area of interest are obtained through aerial impressions. The data obtained are mainly used for map making.
