Description

Infrared aerial camera supporting different-speed image motion compensation function
Technical Field
The application relates to the technical field of aerospace, in particular to an infrared aerial camera supporting an abnormal-speed image motion compensation function.
Background
In the reconnaissance process, a reconnaissance aircraft is required to fly at a high speed and a low altitude for avoiding the surveillance of an enemy radar. The low-altitude high-speed flight greatly improves the battlefield survivability and the depth reconnaissance monitoring capability of the aircraft, but at the moment, severe image shift occurs on the target surface of aerial imaging, so that aerial imaging is blurred, the existence of the image shift greatly influences the imaging quality of a camera, and the resolution of aerial images is obviously reduced. When the image shift exists, the contour of the shot target is unclear, a larger or smaller transition area exists between the target and the surrounding background, the transition area expands along with the increase of the image shift, and when the transition area reaches a certain degree, the imaging of two adjacent targets is overlapped with each other and cannot be distinguished. In forward flight, the aircraft is in a strabismus working state shown in fig. 1 due to the adjustment of the attitude of the aircraft (such as sideways flight) or the adjustment of the pitching angle of the lens of the aircraft camera. The schematic diagram on the target surface is shown in fig. 1, and is characterized in that the image shift directions of the pixel points on the target surface are the same, but the image shift amounts of different pixel areas are different, and the image shift is called different-speed image shift. The strabismus work of the aerial camera has important technical significance, so that the different-speed image shift occupies an important position in the aerial image shift.
Under the push of a digital large environment, photogrammetry digitization is rapidly developing, and aviation photography digitization is due to the development of a large-scale CCD device and high dynamic positioning and attitude determination technology, and the advantages of a digital aviation camera are added, so that the high-resolution digital aviation camera can definitely gradually replace an aviation camera taking a film as a carrier. The aviation digital camera has important application and wide application prospect in the military and civil fields. In the aspect of national economy, china is greatly developing high-altitude earth observation technology, and a high-resolution area array CCD aerial camera has important roles in map aviation, resource census, disaster assessment and other aspects, so that the advantages of the high-resolution area array CCD aerial camera compared with a film aerial camera are obviously reflected. In the field of national defense safety, the high-resolution area array CCD aerial camera has important strategic significance in the aspects of impact effect reconnaissance, battlefield reconnaissance and target dynamic monitoring, reconnaissance information guarantee for troops and the like.
The method for compensating the different-speed image motion of the domestic aerial camera is a method for compensating the different-speed image motion of the aerial camera by using mechanical, optical, image and electronic image motion, wherein a mechanical optical compensation system can greatly increase the weight and the volume of the aerial camera, and the image type image motion compensation method is a post-compensation method and cannot have real-time performance. The technology severely restricts the development of aviation technology in China.
With the development of technology and the increasing maturity of optical imaging technology, the high-resolution real-time transmission type infrared camera also gradually forms an equipment system, and the infrared aerial camera has the characteristics of being good in concealment, strong in smoke penetrating capacity, capable of obtaining infrared radiation characteristics of targets, more visual, easy to interpret and capable of rapidly and accurately identifying the targets, and has the characteristics of higher accuracy, reliability, timeliness and the like, so that the infrared aerial camera is an important component of the aerial imaging equipment system, but the aerial camera reported at present does not support a different-speed image motion compensation function.

Reasons for the generation of different-speed image shift:

In forward flight, the aircraft is in a strabismus working state shown in fig. 1 due to the adjustment of the attitude of the aircraft (such as sideways flight) or the adjustment of the pitching angle of the lens of the aircraft camera.

The forward image shift speeds with equal directions and unequal magnitudes are defined as different-speed image shifts.
