Problems solved by technology
[0004] Usually, the resolution of the original panoramic image obtained by splicing is often very large, and the processing power of the CPU of the panoramic camera is also limited. Therefore, in order to ensure that the CPU can encode the original panoramic image, it is often necessary to reduce the raw image resolution
It can be seen that due to the restriction of the processing power of the CPU of the panoramic camera, the resolution of the target panoramic image obtained by the related technology is relatively low, that is, the definition of the target panoramic image is not high

Embodiment Construction
[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0032] In order to improve the clarity of a target panoramic image, an embodiment of the present invention provides a camera.
[0033] like figure 1 As shown, a camera provided by an embodiment of the present invention includes: a plurality of image sensors 10 , an image processor 20 and a data processor group 30 .
[0034] For example, the image processor 20 may be a module based on a field programmable gate array FPGA chip, but it is certainly not limited t...

An embodiment of the invention provides a video camera. The video camera comprises multiple image sensors, an image processor and a data processor group, wherein the image processor is used for receiving original images collected and sent by the image sensors, splicing the original images and obtaining an original panoramic image, and splitting the original panoramic image into multiple original split images and sending the multiple original split images to the data processor group. When the video camera provided in the embodiment of the invention is used for image processing, the original panoramic image is split into multiple original split images rather than coded directly, then multiple CPUs in the data processor group perform image coding on the original split images; the resolution of each original split image is less than the resolution of the original panoramic image, so that the resolution of each original split image is easy to be within the processing capacity of the CPU, therefore, the resolution of the original panoramic image is not lowered, and the definition of a target panoramic image corresponding to all target split images is easy to improve.
Description
technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video camera. Background technique [0002] Nowadays, a user can use a panoramic camera to shoot a panoramic image, wherein the so-called panoramic image refers to an image with a field of view within a range of 180°-360°. Generally, a panoramic camera specifically refers to a video camera with multiple lenses and multiple image sensors (referred to as sensors for short). [0003] A camera is provided in the related art, and the camera may include multiple sensors, a CPU (Central Processing Unit, central processing unit) and an image processor. Specifically, each sensor in the panoramic camera is used to collect original images corresponding to their respective field of view angles, and the image processor is used to stitch each original image, thereby stitching each original image into an original panoramic image. The CPU of the panoramic camera is used to Image enc...
