Universal measuring camera UMK 10/1318 (VEB Carl Zeiss Jena) on a GDR postage stamp from 1978

A measuring camera is a photographic recording device that is used to determine the position and measure objects or measuring points.

Measurement cameras are characterized by low distortion , have a relatively large focal length and usually three or four frame marks to define the main point of the image . The cameras are mainly used in visible light , but there are also special optics for near infrared and near UV .

The photogrammetry measuring cameras (also called "measuring chambers") are divided into aerial cameras and terrestrial devices. In the past, both were mainly made with films, whereas those in astronomy , called astrographs , were mainly made with photo plates . Today, digital images are mostly taken in both fields .

Special measuring cameras are u. a .:

• Satellite cameras for geodesy and orbit determination tasks
• Photographic zenith telescope ( PZT ) for astrometry
• Zenith cameras to determine the deviation from the perpendicular
• Ballistic cameras for the calibration of missiles such as balloon probes and rocket launches.
