Problems solved by technology

[0005] In scheme 1, the images captured by the two cameras have different overlapping areas at different depths, and it is difficult to splice images that are aligned at all depth levels; in scheme 2, there are no overlapping areas captured by the two cameras, and there are obvious stitching seams In addition, if there are differences between the two cameras, the brightness and / or chromaticity of the images captured by the two cameras will be different when shooting images, and there will be obvious differences when stitching together, and it is difficult to combine the two images without overlapping areas. It is also difficult to determine and eliminate brightness and / or chromaticity differences through image processing methods, which is not conducive to image stitching and imaging

Embodiment 1

[0026] This embodiment provides a camera method, such as figure 1 As shown, the method includes:

[0027] 101. Each imaging device in the imaging device shoots an object respectively, the imaging device includes a plurality of imaging devices, the optical centers of the plurality of imaging devices overlap, and there is an overlapping area between the captured images of two adjacent imaging devices;

[0028] 102. Concatenate and form images captured by each camera device in the camera device.

[0029] In the imaging method of the embodiment of the present invention, the imaging device includes a plurality of imaging devices, and the optical centers of the plurality of imaging devices overlap. The alignment and the fusion of the brightness and / or chroma of the stitched image are beneficial to the analysis and processing of the image stitching; since there is an overlapping area between the captured images of two adjacent camera devices, the effect of the stitching seam on the ...

Embodiment 2

[0031] like figure 2 As shown, the camera method includes:

[0032] 201. Each imaging device in the imaging device shoots an object respectively. The imaging device includes a plurality of imaging devices, and the optical centers of the plurality of imaging devices overlap, and there is an overlapping area between images captured by two adjacent imaging devices.

[0033] 202. Align overlapping areas between images taken by two adjacent camera devices to obtain a spliced ​​image.

[0034] Wherein, aligning the overlapping area between the captured images of two adjacent imaging devices can be by analyzing the images captured by the two imaging devices, looking for paired feature points in the overlapping area, and aligning the images based on the paired feature points (position Correction). A SIFT (Scale-Invariant Feature Transform, scale-invariant feature transformation) method can be used to determine the paired feature points.

[0035] 203. Determine a brightness and / or ...

Embodiment 3

[0054] This embodiment provides a camera system, such as image 3 As shown, the system includes:

[0055] An imaging device 31, the imaging device 31 includes a plurality of imaging devices, the plurality of imaging devices obtain photographed images respectively, the optical centers of the plurality of imaging devices overlap, and there is overlap between the photographed images of two adjacent imaging devices area;

[0056] The processing device 32 is configured to stitch and form the captured images of the various camera devices in the camera device 31 .

[0057] In the imaging system of the embodiment of the present invention, the imaging device includes a plurality of imaging devices, and the optical centers of the plurality of imaging devices coincide. The alignment and the fusion of the brightness and / or chroma of the stitched image are beneficial to the analysis and processing of the image stitching; since there is an overlapping area between the captured images of t...

Abstract

The embodiment of the invention discloses an image pickup method and system. The method comprises the following steps: respectively shooting objects by image pickup equipment in an image pickup device, wherein the image pickup device comprises the multiple image pickup equipment, the optical centers of the multiple image pickup equipment are coincided, and overlapping regions exist among images shot by the adjacent image pickup equipment; and splicing and imaging the images shot by the image pickup equipment in the image pickup device. The method and system can be applied to shooting and processing high-resolution or large-scale images.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to an imaging method and system. Background technique [0002] In the process of high-resolution film and television production, telepresence, etc., it is usually necessary to shoot high-resolution and large-scale images. Due to the limited resolution and shooting range of a single camera, in order to meet the shooting requirements, multiple cameras are usually used for shooting, and then the images shot by each camera are spliced ​​into an image. [0003] In the prior art, there are two schemes for shooting with two cameras. In scheme one, the two cameras are placed in parallel, and the images captured by the two cameras are spliced ​​and formed. The images captured by the two cameras overlap at different depths. different. In the second scheme, the equivalent optical center of one camera coincides with the optical center of the other camera through a mirror, and the sh...
