Abstract

The invention provides a light field imaging system. The light field imaging system comprises a microlens array, a light beam guiding unit, an imaging unit and an image processing unit, wherein the microlens array comprises a plurality of microlens units used for focusing light beams; the light beam guiding unit is used for guiding the light beams imaged through the microlens array so as to enable light having a larger included angle with a light axis of the light field imaging system to be transmitted to the imaging unit through the microlens array; the imaging unit is arranged on a focal plane of the microlens array and is used for receiving light transmitted by the microlens array so as to carry out light sensitive imaging; and the image processing unit is used for processing electric signals collected by the imaging unit. According to the invention, the light field imaging system is simple in structure and is capable of collecting light with a larger view angle for light field imaging, so that the view field angel of the light field imaging system is effectively enlarged.

Description

technical field [0001] The invention relates to the technical field of light field imaging, in particular to a light field imaging system with a large viewing angle. Background technique [0002] The imaging process of traditional cameras adopts a two-dimensional projection method for three-dimensional space scenes, and only accumulates the intensity of light on the detector pixels, that is to say, only the spatial distribution of objects on the image plane is considered, and the The propagation direction information of the light is discarded, and the reshaping of the image is limited. [0003] In contrast, light field imaging technology retains the possibility of image reshaping, can obtain more flexible and diversified image information, and has a very broad application prospect. For example, the digital refocusing technology of light field pictures can be used to calculate the two-dimensional images focused at different depths, so as to realize the function of "taking pi...
