Problems solved by technology

Although such a panorama can completely present the scene of the viewpoint space, it is not enough in the emphasis of the scene: because the scene is presented without distinction, it is difficult for the observer to grasp the core scene of the image at the first time
And because of the panorama Figure 1 Generally, it is composed of multiple two-dimensional images, so the data volume is large, and it is not easy to save and transmit

Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] The present invention selects the attention center in the rectangular spherical panorama expansion diagram, and implements axis-changing expansion on the panorama, so that the attention center can coincide with the image center of the new expansion diagram. Then set a certain range around the focus center as the focus area, and compress other parts of the image, that is, only one point is kept among multiple adjacent points, and the number of image grid points and the number of rgb groups are reduced at the same time. Therefore, the data size of the unfolded diagram is also reduced, which facilitates the storage and transmission of the unfolded diagram.

[0022] After receiving the compressed image, a decompression algorithm can be run to return the image to its original size. The area of ​​interest of the picture after decompression is exactly the...

Abstract

The invention discloses a method for generating a non-uniform resolution spherical panoramic graph. A new ball journal and a new cutting line are selected and thus a focus central point is located at a center of a picture, so that intersection of a focused area and an expended picture boundary can be avoided and thus later-stage compression processing can be carried out conveniently. According to the invention, an image is compressed in a divided block mode, so that the data volume is reduced and storage and transport become convenient; and the compressed image is expanded again to obtain a non-uniform resolution spherical panoramic graph, so that an observer can identify core scenery and thus the visual impact of the core scenery of the image is enhanced.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for generating a panorama with non-uniform resolution based on image compression, and is especially convenient for saving and transmitting spherical panorama images. Background technique [0002] The panorama can present a 360° full-space scene centered on the viewpoint, and the observer can freely choose an angle to watch the panorama. Spherical panorama is a kind of panorama, which is imaged by central projection method, and its observation mode is closest to that of human eyes. In a general, uniform-resolution spherical panorama, all objects are imaged with the same quality. Although such a panorama can completely present the scene of the viewpoint space, it is not enough in the emphasis of the scene: because the scene is presented without distinction of size, it is difficult for the observer to grasp the core scene of the image at the first time. And becau...
