Abstract

The invention provides a wide-view-field high-resolution camera shooting device and method based on calculation aberration compensation. The wide-view-field high-resolution camera equipment based on calculation aberration compensation comprises an optical input module, a scanning micro-lens array module and an imaging module, wherein the optical input module comprises an optical lens; the scanningmicro-lens array module comprises a displacement device and a micro-lens array; the imaging module comprises an image sensor; the optical input module shoots a scene through any optical lens to collect optical information; and the scanning micro-lens array module drives the micro-lens array to perform periodic movement scanning through the displacement device, and further transmits the optical information collected by the optical lens to the image sensor in the imaging module.

Description

technical field [0001] The invention relates to the fields of light field imaging, phase space imaging and macroscopic optical imaging, in particular to a wide-field-of-view high-resolution imaging device and method based on computational aberration compensation. Background technique [0002] In recent years, ultra-high pixel count imaging has gradually entered people's field of vision. With the popularization and proliferation of industries or equipment such as machine vision, drones, and high-definition surveillance systems, people's demand for high-resolution, large-pixel imaging has become increasingly apparent. [0003] The three limiting conditions that determine the imaging quality or imaging resolution of the imaging system are as follows: First, the sampling rate of the image sensor: the popular image sensors are mainly divided into two types: CCD and CMOS. Being smaller is conducive to the generation of higher-resolution images; the second is the optical diffracti...
