Description
Technical field
The present invention relates to Aerial photography technical field more particularly to a kind of aerial survey image capture systems.
Background technique
Aerocamera (aerial camera) is installed on aircraft from the optical instrument of aerial intake surface target
(see figure).First semi-automatic aerocamera begins to use during the World War I.After, aerocamera is gradually
Development, type increase, and performance constantly improves.
By light source difference, camera, night camera and general camera between daytime can be divided into.Camera is taken the photograph using daylight illumination between daytime
Shadow, night camera utilize artificial-light photography, and general camera can be dual-purpose round the clock.By construction features, and Frame projection, course line can be divided into
Formula (also known as clearance type) and panoramic camera.Frame camera framing shot has certain interval between each breadth;Course line formula phase
Machine is continuously shot along heading, regardless of breadth;Panoramic camera shoots wholly or largely ground along the lateral of aircraft
Width can carry out large area photography with the continuous flight forward of aircraft.In addition, aerocamera can also be according to camera lens coke
Away from length, the size at visual angle etc. classify.The element of aerocamera is camera body and executor.According to
Camera body is generally made of the part such as spool box, camera bellows, object lens, is primarily used to form optical image and film is made to be dived
Shadow.Work of the executor for far distance control and inspection camera.There is cable to be connected between camera and executor.Aviation
Camera internal is generally equipped with optical system, recorder and various operating mechanisms.The taken the photograph ground target photo of aerocamera point
Resolution is higher, convenient for identification precision target, thus is widely applied.Its main technical parameters is focal length, visual angle, resolution
Rate, film quantity, duty cycle and exposure time range.Its construction features and Specifeca tion speeification are different, and use scope is not yet
Together.Low altitude high speed intelligence photography mostly uses that the duty cycle is short, the time for exposure is short, the short focus aerial photography with image motion compensation device
Machine.More frequently with the film quantity long-focus aerocamera with image motion compensation device of high altitude surveillance photography.Mapping photography is common
Distort small, short focus wide-angle aerial camera.The mountable several different types of aerocameras on an aircraft, with
Just it takes photo in the sky under various conditions.The developing direction of modern Aviation camera is that focal range is big, film quantity is more, claps
, high-resolution wide according to visual field, high image quality and increasingly automated.
But if several different types of aerocameras are installed on aircraft, need aboard installation settings it is multiple
Observation window not only will affect the overall structural strength of aircraft, and the air of aircraft is moved if observation window is protruded above from airframe
Mechanical characteristic equally will cause influence.
