Abstract

The invention relates to the technical field of optical imaging, discloses an image acquisition method and system, and realizes the selection of an imaging area and the improvement of the overall performance in a novel light beam deflection mode. The method comprises the following steps that a light beam filtering module and a light beam selection module are arranged in front of an image sensor; the light beam selection module comprises at least one stage of lens group, and each stage of lens group consists of a polarization grating and an electric control liquid crystal box respectively; eachelectric control liquid crystal box is provided with at least two states; in the state set of the electric control liquid crystal boxes arranged by all the light beam selection modules, each state subset respectively corresponds to the image subareas which are not completely overlapped outside the lens one by one; and the program control corresponding electric control liquid crystal boxes realizethe acquisition of corresponding image subareas by state switching, and relative displacement motion among the components does not occur in the switching process of the image subareas. The technologyof the invention can be widely applied to application scenes such as multi-lane monitoring and the like.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an image acquisition method and system. Background technique [0002] In recent years, more and more attention has been paid to beam manipulation technology. In particular, the research on light field control technology based on new optical devices is the most popular. However, according to the existing camera technology, devices capable of achieving ultra-high definition and large field of view are usually very expensive and have many shortcomings. Contents of the invention [0003] The purpose of the present invention is to disclose an image acquisition method and system, which realizes the selection of imaging regions and the improvement of overall performance by a new beam deflection mode. [0004] To achieve the above purpose, the present invention discloses an image acquisition method, comprising: [0005] A beam filtering module and a beam selection module are...
