Title:
IMAGE TRANSMISSION METHOD AND APPARATUS, IMAGE DISPLAY METHOD AND APPARATUS, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/055925
Kind Code:
A1
Abstract:
The present application relates to an image transmission method and apparatus, a computer device, a storage medium, and a computer program product. The method comprises: obtaining a spherical panoramic image according to a wide-angle image acquired from a target environment; cropping an image of interest from the spherical panoramic image on the basis of a preset field of view and an Euler angle corresponding to a rotation attitude of a target object when using a virtual reality device; stitching the image of interest and a down-sampled wide-angle image to obtain a stitched image, wherein the down-sampled wide-angle image is obtained by down-sampling the wide-angle image; and transmitting the stitched image to the virtual reality device. The use of the method can reduce the transmission bandwidth.
