Problems solved by technology

Although these three technologies have their own advantages, they all have a common disadvantage. The correct effect needs to be viewed at a specific distance. Problems such as ghosting, crosstalk, dizziness, and visual fatigue will occur at closer or farther distances.

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] figure 1 In step 101, system calibration is performed on each CCD camera in the multi-viewpoint light field acquisition system. Before sampling the dynamic scene, each CCD camera is calibrated to obtain the internal and external parameters of the camera. The method used is to keep the camera still, shoot the calibration boards in different positions and different attitudes, and then calculate the camera’s internal parameters by matching the camera projection matrix.

[0020] In this embodiment, any camera array must be calibrated before use and can be used by subsequent algorithms, assuming that the world coordinate value of a certain point in the dynamic scene is (X, Y, Z), in the CCD camera imaging surface The coordinate value is (u, v), the focal length of the CCD camera is f, the physical distance between horizontal pixel...

Abstract

The invention relates to the technical field of naked-eye 3D display, and discloses a naked-eye 3D image acquisition and generation method. The present invention first performs system calibration on each of the CCD cameras in the multi-viewpoint light field acquisition system, then performs dynamic scene acquisition, performs foreground and background segmentation on the acquired target object information, and then separates the foreground image of the target object information Output and group, and finally calculate the naked-eye 3D mapping matrix, and combine the external parameters of the CCD camera to process the foreground image to obtain a naked-eye 3D composite image with the correct proportion. The naked-eye 3D mapping method based on the dynamic light field not only has a more realistic three-dimensional effect, but also is compatible with far and near viewing, so that the viewer will not experience problems such as dizziness and visual fatigue.

Description

technical field [0001] The invention relates to the technical field of naked-eye 3D display, in particular to a method for collecting and generating naked-eye 3D images. Background technique [0002] In recent years, with the continuous application of naked-eye 3D technology, it has brought consumers a new visual experience. Glasses-free 3D has the characteristics of multi-perception, immersion, interactivity, and conception. It can break the traditional display and allow consumers to easily experience the stereoscopic image effect of unlimited technology without wearing glasses. It will have broader and more practical application scenarios in the future. . [0003] At present, there are three main technologies used in naked-eye 3D display devices: light barrier, lenticular lens, and pointing light source. Although these three technologies have their own advantages, they all have a common disadvantage. The correct effect needs to be viewed at a specific distance. Problems ...
