Microlens array imaging system

Abstract

The invention relates to a microlens array imaging system. The system comprises a microlens array, non-transparent light-blocking processing structures, a photosensitive pixel array and an imaging result processor, wherein the microlens array includes plural microlenses which are arranged adjacently; the non-transparent light-blocking processing structures are arranged between each two adjacent microlenses and form a planar or curved-surface grid structure with the plural microlenses; the photosensitive pixel array includes plural photosensitive components arranged under each microlens; and the imaging result processor receives electrical signals output by the photosensitive pixel array, converts the electrical signals into image information and carries out decoding and processing on the image information. In the invention, a problem that each microlens resolution is low is overcome, the integral resolution of a camera possessing a light field acquisition function is increased, each microlens is ensured to carry out independent imaging, the mutual interference among imaging results is avoided, and data correctness is ensured.

Description

technical field [0001] The invention relates to an imaging system, in particular to a microlens array imaging system. Background technique [0002] Most of the cameras currently on the market have a single main lens, which converts the three-dimensional real world into a two-dimensional image, resulting in a large amount of information loss. However, in order to restore three-dimensional information from two-dimensional image information, it is mostly difficult to perform three-dimensional reconstruction. Therefore, a camera capable of collecting light fields is urgently needed to solve this problem. [0003] At present, the cameras with the function of collecting light field are mainly camera arrays and light field cameras on the market. Among them, the problem of the camera array is that it is large in size, and it takes a lot of manpower and time to adjust the relative positions of the cameras; while the light field camera is It is an integrated structure, which uses a m...

However, in order to restore three-dimensional information from two-dimensional image information, it is mostly difficult to perform three-dimensional reconstruction. Therefore, a camera capable of collecting light fields is urgently needed to solve this problem.

[0003] At present, the cameras with the function of collecting light field are mainly camera arrays and light field cameras on the market. Among them, the problem of the camera array is that it is large in size, and it takes a lot of manpower and time to adjust the relative positions of the cameras; while the light field camera is It is an integrated structure, which uses a microlens structure to record the angle information of the light, but the imaging data of the light field camera is large, the image processing time is long, and the real-time performance is poor, and the main lens cannot be removed, resulting in a relatively small overall size of the camera. Large, not suitable for small aircraft such as orthopters
