Abstract

The invention discloses a method and a device for rapidly acquiring an elemental image based on a camera array, mainly aiming to solve the problem on acquiring an elemental image array and provide a simple and convenient elemental image array acquisition means for acquisition and application of the three-dimensional information of various scenes and naked-eye three-dimensional display. At present, a lens array or a camera array are generally adopted for acquiring the elemental image array in an integrated imaging optical acquisition process. For the traditional optical acquisition means, the elemental image array which is constituted by a large number of elemental images and is matched with the number of a lens array needs to be acquired, the defects of low acquisition speed, complex equipment and high manufacture cost are existent, and the traditional optical acquisition means cannot be popularized and applied in large scale. The device disclosed by the invention comprises a 2*2 camera array of rectangular arrangement and an electronic computer. According to the invention, by starting from the relevance among elemental images in an elemental image array acquired through integrated imaging, the elemental image array is acquired rapidly by using the camera array constituted by four cameras, and thus, the complexity and the cost of the device are reduced.

Description

Technical field [0001] The invention belongs to the technical field of three-dimensional imaging and display, and mainly proposes a method and device for quickly acquiring element images based on a camera array. The main solution is to obtain the element image array, which provides a convenient means of obtaining the element image array for realizing the acquisition and application of 3D information in various scenes and the naked eye 3D display. Background technique [0002] The naked-eye 3D display technology plays an important role in restoring the real display. Integrated imaging 3D display technology, as a naked eye 3D display technology, has the advantages of continuous viewpoint, no visual fatigue, and no need for auxiliary devices. The naked eye 3D display technology based on integrated imaging requires an element image array to display naked eye 3D information. The element image array can generally be acquired by computational integrated imaging, or by optical means. ...
