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...

Abstract

A video camera provided by an embodiment of the present invention includes a plurality of image sensors, an image processor, and a data processor group. The image processor is used to receive the original image collected and sent by the image sensor, splice the original image to obtain the original panoramic image, split the original panoramic image into multiple original split images and send the data to the processor group. When the camera provided by the embodiment of the present invention is used for image processing, the original panoramic image is not directly image-encoded, but is first split into a plurality of original split images, and the multiple CPUs in the data processor group respectively encode each The original split image is used for image encoding. Since the resolution of each original split image is smaller than the resolution of the original panoramic image, the resolution of each original split image is easily within the processing power of the CPU, so there is no need to reduce the resolution of the original panoramic image. The rate is beneficial to improve the clarity of the target panorama image corresponding to all the target split images.

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...
