High-resolution calculation imaging system and method based on camera array aperture synthesis

Abstract

The invention discloses a high-resolution calculation imaging system and method based on camera array aperture synthesis. The system comprises an aperture synthesis quick multi-frame collection module, a computer control module, and an image processing module. The aperture synthesis rapid multi-frame acquisition module is a camera array comprising a plurality of area-array detectors, and the plurality of area-array detectors in the camera array are used for synchronously acquiring low-resolution images of the same area of the to-be-measured object; the computer control module is used for storing corresponding multi-frame low-resolution images synchronously acquired by the plurality of area array detectors; and the image processing module is used for fusing and reconstructing the multiple frames of low-resolution images into a high-resolution image. The imaging system is simple in optical path structure and low in cost, pixel resolution limitation and optical resolution limitation of the imaging system can be solved, and rapid high-resolution imaging is achieved.

Description

technical field [0001] The invention relates to the technical field of photography and imaging, in particular to a high-resolution computational imaging system and method based on camera array aperture synthesis. Background technique [0002] Resolution is one of the important indicators to evaluate the performance of imaging system. In an actual optical system, the image acquisition process is very susceptible to multiple factors such as environmental interference, device performance cost, and non-ideal sampling, which cause the pixel resolution and optical resolution of the imaging system to be limited, so that the imaging system can only obtain images containing noise. , blurred and degraded low-resolution images. Low-resolution images mean low image quality and less information, which cannot provide detailed features for observing the fine structure of the measured object. The general imaging system is an aperture-limited system, which can be regarded as a low-pass fil...

Problems solved by technology

However, large-aperture lenses mean extremely difficult lens processing technology and extremely high lens manufacturing costs. At the same time, the disadvantages of not being easy to transport and fix will also cause obstacles to the construction of imaging systems.
