Multi-scale multi-aperture optical imaging system

Abstract

The invention discloses a multi-scale multi-aperture optical imaging system. The multi-scale multi-aperture optical imaging system comprises a center optical imaging system and four secondary optical imaging systems having complete identical optical structures, wherein the center optical imaging system is a rotary symmetric system, the optical axis and the system center axis are superposed, the four secondary optical imaging systems are arranged at the back of the center optical imaging system, from the perspective of image cross sections, four optical axes of the secondary optical imaging systems are distributed on tip tops of a rectangle which takes the optical axis of the center optical imaging system as the center, and parallel lights emitted from different perspectives by a target are respectively imaged through the center optical imaging system and the four secondary optical imaging systems on different coordinate points on an image plane of one same detector. Independent multiple target images can be acquired by applying the multi-scale multi-aperture optical imaging system to acquire target object information, the center image resolution is higher than the secondary image resolution, images respectively have certain pixels superposed in the field of view, and the multi-scale multi-aperture optical imaging system can provide excellent support for subsequent data processing.

Description

technical field [0001] The invention belongs to the field of visible light optical system design and relates to a multi-scale multi-aperture optical imaging system. Background technique [0002] Image registration refers to seeking a certain spatial transformation for one or more images so that it can achieve spatial consistency with the corresponding points on another image. [0003] The essential problem of image registration is to find out an image transformation model to correct the deformation of the image. Due to the influence of various factors such as sensors and imaging conditions, the diversity of image registration techniques is caused. With the development of science and technology, image registration technology has also made great progress, and there are various registration methods, but there is no one registration technology that is widely applicable. For different types of images to be registered, it is often necessary to Depending on the particular situati...

Problems solved by technology

[0006] The two structural types of Topgang and Rushal are both symmetrical about the aperture stop, which can better correct off-axis aberrations, but the field of view of the image square is large, the uniformity of illumination on the image plane is poor, and the rear working distance is short.
