Problems solved by technology

However, due to the interference of redundant light rays on the stereo sub-image and the discarding of the distorted area during the acquisition process, the display quality of the reconstructed image is greatly reduced.

Embodiment Construction

[0024] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention.

[0025] 1. Use the virtual camera array in MAYA to simulate the actual optical lens array

[0026] figure 1 For the flowchart of the present invention, the virtual camera array set up in MAYA and the virtual scene of shooting are as figure 2 As shown, if you want to use the virtual camera to simulate the actual optical lens, you need to ensure that the focal length and shooting range of the two are the same. Keeping the same focal length can be achieved by adjusting the focal length of the virtual camera in the software. To keep the shooting range consistent, you need to ensure that both If the shooting angles are the same size, you need to adjust the size of the virtual camera’s horizontal and vertical apertures to change the size of the film so that it satisfies the followi...

Abstract

The invention discloses a method for integrated image reconstruction based on block matching, and belongs to the technical field of 3D image processing. The method comprises the following steps: constructing a virtual camera photographing array through MAYA software, adjusting the related parameters of a virtual camera, and enabling the virtual camera to simulate a lens array in an actual opticalsystem; obtaining reconstructed image based on different sight points through a computer reconstruction algorithm based on a lens array model, determining the occurrence positions of three types of distortion: straight distortion, l-shaped distortion and L-shaped distortion, and a correct matched block region; replacing a distortion region through a matched block of a distortion region, thereby obtaining an improved reconstructed image of the sight point. The method can enlarge a display range of the reconstructed image based on different sight points, can improve the utilization rate of a three-dimensional element image array, can avoid the interference from redundant light in a collection process, and finally improves the quality of an image in integrated imaging virtual reconstruction.

Description

technical field [0001] The invention belongs to the technical field of 3D image processing, in particular to a method for reconstructing an integrated imaging image based on block matching. Background technique [0002] As a true three-dimensional display technology, integrated imaging technology has attracted people's attention due to its many advantages such as no need for visual aid display equipment, no fatigue in viewing, and good display effect. Its research content mainly includes the acquisition of elemental image arrays , the reconstruction of displayed images, and the application in actual display devices. The research directions mainly focus on three aspects: all-optical integrated imaging, computer-aided integrated imaging and computer-aided integrated imaging, among which computer-assisted integrated imaging is Use real microlens arrays and photoelectric devices such as CCDs to collect images to obtain stereoscopic element image arrays. During the display proces...
