A light field imaging device with stacked camera array structure

Abstract

The invention belongs to the field of optical imaging and mechanical manufacturing, and in particular relates to a light field imaging device with a stacked camera array structure. The imaging device includes a support component and a plurality of cameras; the support component is composed of a base and several support rods; the cameras are fixedly installed on the support rods, and an equal number of cameras are installed on each support rod; On the vertical plane, each camera on the same support pole is arranged sequentially from top to bottom at different pitch angles; on the horizontal plane, cameras on different support poles at the same height are arranged from left to right at different azimuth angles Configure in turn. The present invention provides basic conditions for obtaining spatial light field information through multiple imaging of spatial points, and at the same time provides necessary prerequisites for splicing and obtaining spatial scene information of a larger field of view through the extension of the field of view of adjacent cameras. The invention has the advantages of simple structure, low cost and easy realization and popularization.

Description

technical field [0001] The invention belongs to the field of optical imaging and mechanical manufacturing, and in particular relates to a light field imaging device with a stacked camera array structure. Background technique [0002] Since the birth of imaging devices such as cameras and video cameras, people have been working towards the two directions of "seeing clearly" and "seeing widely". In addition, with the development of digital image processing technology, the innovation of imaging system structure design and the emergence of optical imaging technology, people are not only satisfied with the acquisition and display of two-dimensional information of real scenes in nature, but also expect to be able to obtain spatial scene information. Three-dimensional structural information, even higher-dimensional full-light field data information. Compared with traditional imaging methods that only record two-dimensional information, light field imaging technology has richer inf...

Problems solved by technology

[0008] In order to solve the above-mentioned technical problems, the present invention aims at the problem that various existing camera arrays cannot realize large-field-of-view and high-resolution light-field imaging at the same time, and proposes a light-field imaging device for a stacked camera array. The field of view of each camera overlaps and extends gradually in the horizontal and vertical directions, so that the information of the same spatial point is captured by multiple cameras at the same time, providing the possibility to obtain spatial light field information; at the same time, the field of view of adjacent cameras is extended Provide the basic premise for splicing to obtain spatial scene information with a larger field of view
