Embodiment Construction

[0043] The application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain related inventions, rather than to limit the invention. It should also be noted that, for ease of description, only parts related to the invention are shown in the drawings.

[0044] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0045] Because the panorama needs to accommodate 360° full spatial data, it occupies a large data space. Appropriate pixel compression can reduce the amount of calculation and data, and facilitate storage and transmission.

[0046] For ease of description, the transmission system, panorama compre...

Abstract

The invention discloses a compression and decompression method of a panoramic image, an apparatus and a system thereof. On one hand, through the compression method of the panoramic image, a compression image is acquired. The method comprises the following steps of dividing the panoramic image into an interesting area and an uninteresting area; carrying out compression processing on the uninteresting area; and synthesizing the uncompressed interesting area and the compressed uninteresting area into the compression image. On the other hand, through the decompression method of the compression image, a decompression image is acquired. The method comprises the following steps of extracting the uncompressed interesting area and the compressed uninteresting area in the compression image; carrying out decompression processing on the uninteresting area; and synthesizing the decompressed uninteresting area and the interesting area into the decompression image.

Description

technical field [0001] The present disclosure generally relates to the technical field of image compression and decompression, and in particular, relates to a compression and decompression method, device and system for panorama images. Background technique [0002] With the development of high-definition display technology, the resolution of images is getting higher and higher, especially for panoramas covering 360-degree scenes, the huge amount of data has caused great difficulties in the storage and transmission of panoramas. Therefore, it is necessary to compress the panorama to reduce storage space and network resources occupied by transmission. [0003] The existing panorama technology usually presents all the angle pictures captured by the panoramic camera regardless of the size of the captured spherical panorama. Such a panorama not only has a large amount of data, but also provides too much redundant information that users do not care about. The current existing co...
