Problems solved by technology

However, when the optical system is assembled and adjusted, the defocus amount of each field of view and the level of the line array will be coupled with each other and interfere with each other. According to the traditional method, repeated attempts are required, and the efficiency is low. More efficient methods need to be explored. Realize the rapid adjustment of the focal plane of the space surveying and mapping camera

Abstract

The invention relates to a space mapping camera focal plane installation and adjustment device and method, and particularly relates to a computer-aided space mapping camera rapid installation and adjustment method, belonging to the technical field of spaceflight optical remote sensors. The focal plane installation and adjustment efficiency of a space mapping camera can be remarkably improved, thefocal plane can be rapidly and accurately adjusted, batch production is facilitated, and the development period of products is shortened; and the camera system integration can be completed by correcting the focal plane gasket for one time in the method, so that the situation that a conventional space mapping camera system integration needs a plurality of times of iteration is avoided.

Description

technical field [0001] The invention relates to a device and method for adjusting the focal plane of a space surveying and mapping camera, in particular to a computer-aided method for rapidly adjusting the focal plane of a space surveying and mapping camera, which belongs to the technical field of aerospace optical remote sensors. Background technique [0002] Space surveying and mapping camera is an important technical equipment for civil and military map drawing, and its imaging quality and geometric characteristics are very important. High-quality imaging capabilities and stable boresight angles, internal orientation elements and distortion, and line array parallelism are essential conditions for space mapping cameras. [0003] After completing the optical adjustment of the lens, the space mapping camera needs to systemically integrate the lens assembly and the focal plane assembly to realize the precise connection between the lens and the focal plane assembly, and ensure...
