Problems solved by technology

The existing panoramic camera loses the direction information of the light, and the human eye can only see the image with fixed focus, but cannot refocus
Since this does not conform to the visual characteristics of the human eye viewing the three-dimensional world, it reduces the visual experience of the human eye watching the panorama

Embodiment 1

[0026] see Figure 4 , when N=2, the only two light field cameras 1 are fixed back to back on a support 2 , and the normals of the lenses of the two light field cameras coincide. According to the formula , the shooting angle of a single light field camera , the FOV of the light field camera selected in this embodiment is 240°, which meets the above requirements. Each light field camera simultaneously collects three aspects of information about the color, brightness and direction of light within a 240° angle, and stores the three aspects of information collected as a light field image. The light field images taken by the two light field cameras are partially overlapped, and the light field images of the overlapping parts are fused, that is, the color, brightness and light direction of the light in the overlapping parts are fused to obtain a 360° panoramic light field image.

Embodiment 2

[0028] see Figure 5 , when N=3, three light field cameras 1 are evenly distributed and fixed on a circular support 2, and the normals of the lenses of two adjacent light field cameras 1 are 120°, according to the formula , the shooting angle of a single light field camera 1 , the FOV of the light field camera 1 selected in this embodiment is 160°, which meets the above requirements. Each light field camera simultaneously collects three aspects of information about the color, brightness and light direction of light within an angle of 160°, and stores the three aspects of information it collects as a light field image. The light field images taken by any two adjacent light field cameras partially overlap, and the light field images taken by all two adjacent light field cameras are stitched together to obtain a 360° panoramic light field image.

Embodiment 3

[0030] see Figure 6 , when N=4, four light field cameras 1 are evenly distributed and fixed on a circular support 2, and the normals of the lenses of two adjacent light field cameras are 90°, according to the formula , the shooting angle of a single light field camera 1 , the FOV of the light field camera 1 selected in this embodiment is 120°, which meets the above requirements. Each light field camera 1 simultaneously collects three aspects of information about light color, brightness and light direction within an angle of 120°, and stores the three aspects of information collected as a light field image. The light field images taken by any two adjacent light field cameras partially overlap, and the light field images taken by all two adjacent light field cameras are stitched together to obtain a 360° panoramic light field image.

Abstract

The invention provides a light-field panorama camera. The light-field panorama camera comprises N light-field cameras, and N is greater than or equal to 2, the light-field cameras are uniformly distributed and fixed on a circular support, the shot angle of each light-field camera is FOVcm, the overlapped angle of light-field images collected by every two adjacent light-field cameras is FOVomtp; and a panorama light-field image captured by the light-field panorama camera provided by the invention can allow refocusing in 360-degree angle visual angle. When a panorama is watched by eyes, the eyes can be selectively focused on any object, and the eyes can obtain a more realistic panorama watching effect.

Description

technical field [0001] The invention relates to the technical field of panoramic camera imaging, in particular to a light field panoramic camera. Background technique [0002] Existing panoramic cameras can only capture 360° 2D images, that is, only the color and brightness information of light can be collected, but the direction information of light cannot be collected. Therefore, existing panoramic cameras can only provide viewing of "fixed" focused images, but cannot "refocus". [0003] see Figure 1a and Figure 1b , the 360° panorama seen by both eyes can only be focused on a cylindrical surface with a fixed radius when using the existing panoramic camera. When the human eye is watching the three-dimensional world, the ciliary muscle can relax and contract, so as to focus on objects at different distances. see Figure 2a and Figure 2b , the human eye can choose to focus on cylindrical surfaces with different radii, the ciliary muscle relaxes when focusing on the d...
