A Parameter Setting and Adjusting Method Applied to Stereo Mapping Camera

Abstract

The invention discloses a parameter setting and adjusting method applied to a stereo mapping camera. The method comprises the following steps: searching a stereoimaging model of a three-line-array mapping camera, providing the differences of the pupil-entrance radiances when three cameras are used for imaging the same target under different imaging conditions according to mounting modes and satellite orbit parameters of different cameras, and providing the output response differences of the three cameras in combination with the camera actual response degree and the differences of in-orbit integral time so as to adjust the other two cameras in real time by setting an imaging parameter of one camera (an envisage camera). The dynamic matching setting of the camera imaging parameter under different latitudes is provided, and the radiation quality of a stereo image is improved.

Description

technical field [0001] The invention relates to a parameter setting and adjustment method applied to a stereo surveying and mapping camera, and belongs to the technical field of aerospace optical remote sensor application. Background technique [0002] Aerospace surveying and mapping technology is an important part of aerospace earth observation and imaging technology, and it is a very important type of earth imaging observation satellite. It has gradually developed from an important part of military combat space support system to an important part of modern warfare combat capabilities. In the field of civilian surveying and mapping technology, aerospace surveying and mapping technology is also a modern and efficient means of surveying and mapping technology. [0003] Surveying and mapping cameras are important payloads on surveying and mapping satellites. The CCD surveying cameras that use push-broom imaging have attracted widespread attention in the world. According to the...

Problems solved by technology

[0005] At present, the calculation of the sun altitude angle only considers the orbital parameters of the satellite, and the obtained sun altitude angle observed by the satellite is the camera, and there are usually several cameras on the surveying and mapping satellite, and the installation methods of different cameras on the satellite are inconsistent, resulting in different cameras. When imaging the same target, the imaging time and observation angle are different. This difference in observation conditions will cause changes in the atmospheric transmission path, thereby affecting the entrance pupil radiance of the same target before reaching different cameras.
