Embodiment 1

[0023] figure 1 , 2 It is a schematic structural diagram of a 3D image acquisition system provided in Embodiment 1 of the present invention. This embodiment is applicable to the case of capturing a 2D image for 3D imaging. The acquisition system can be installed on an intelligent terminal. Specifically, the acquisition system 1 includes several camera devices, specifically, each camera device includes a first camera device 11 and a second camera device 12 . The acquisition system 1 also includes an image preprocessing device 13 connected to each camera device.

[0024] Wherein, the number of the first camera devices 11 is at least two, and the optical axes of the first camera devices 11 are in the same direction and are perpendicular to the straight line. Compared with the second camera device 12, all the first camera devices 11 are located in the center. For example, if there are four cameras in total, the middle two are the first camera devices 11 , and the two sides are...

Embodiment 2

[0047] Such as Figure 4 As shown, this embodiment provides a three-dimensional image display system. The display system can be installed in a separate electronic device, and connected with the acquisition system through an external interface. It can also be integrated with the acquisition system into an intelligent terminal. The display system is aimed at the case that the optical axes of all the camera devices are parallel. The display system is used to form a three-dimensional image according to a common image area in multiple received two-dimensional images. Wherein, the three-dimensional image is, for example, a naked-eye three-dimensional image.

[0048] The display system 2 includes: an initialization module 20 , a preprocessing module 21 , an estimation module 22 , a space reconstruction and processing module 23 , a viewpoint projection processing module 24 , and an interleaving module 25 .

[0049] The initialization module 20 is used to determine the pixel size o...

Embodiment 3

[0085] The difference from the second embodiment is that, especially for the case where the second camera is tilted toward the center direction by a preset angle, the preprocessing module 21 is also used to The deflection angle is preset, and the two-dimensional images captured by each second camera device are mapped onto the screen to complete the optical axis matching obtained by different optical axes.

[0086] Specifically, such as Figure 11 As shown, the preprocessing module 21 determines that the image captured by the second camera 12 is projected on the plane perpendicular to the optical axis and intersecting the screen according to the optical axis of the second camera 12 . For example, the projected position of point pt in the display space on the plane is pt1, and similarly, the point where the second camera 12, point pt, and point pt1 intersect with the screen is pt2, and the preprocessing The module 21 determines the pt2 point as the two-dimensional image displa...

Abstract

The invention discloses a three-dimensional image obtaining system, a three-dimensional image display system, and an applicable intelligent terminal, wherein the obtaining system comprises at least two centred first photographing devices, at least one second photographing device and an image pre-processing device, wherein the at least two centred first photographing devices and the at least one second photographing device are arranged on the same straight line; the first photographing devices are same in optical axis direction, and vertical to the straight line; photographed images include a common image area; the second photographing device is arranged at one side of the first photographing devices, and used for supplying the image area, which cannot be commonly photographed by the first photographing devices due to shielding; the image pre-processing device is connected with the various photographing devices; the photographing device is the first photographing device or the second photographing device; and the image pre-processing device is used for pre-processing the various connected photographing devices and / or the various photographed images based on three-dimensional reconstruction. By means of the three-dimensional image obtaining system, the three-dimensional image display system, and the applicable intelligent terminal disclosed by the invention, the problem that a three-dimensional image cannot be constructed by a shielded region in an image photographed by the two first photographing devices can be solved.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular to a three-dimensional image acquisition system, a display system, and an applicable intelligent terminal. Background technique [0002] The 3D image is based on 3D reconstruction of two views with overlapping images. During the reconstruction process, affected by the overlapping areas of the two views, the 3D reconstruction system can only construct a 3D image for the overlapping areas. As for non-overlapping regions, stereoscopic rendering cannot be performed due to lack of image data. In this way, the middle area in the three-dimensional image is a stereoscopic image, and the peripheral area is a two-dimensional image, and the stereoscopic effect is poor. [0003] In order to solve the above problems, in the prior art, multiple images are taken around the object to be displayed stereoscopically, and then the 3D reconstruction system uses the multiple im...
