Problems solved by technology

However, this traditional technical solution does not take advantage of the fact that the content of the photos taken when the camera's position and orientation are fixed has a high degree of correlation, so there is a waste of data bandwidth during transmission.

Abstract

An embodiment of the invention discloses an image transmission method. The method comprises the following steps that a camera shoots a current image aiming at an object; a local data compression model is used to select one of several compression rules to compress the current image; a compressed data packet of the current image is sent to far-end equipment; the far-end equipment receives the compressed data packet, a far-end data compression model is used to decompress the compressed data packet and decompressed image data is used to update the far-end data compression model; and according to a difference between the current image and one or more historical images in the data compression model, one of the compression rules is selected, and the compressed data packet includes compressed image data and auxiliary data.

Description

technical field [0001] The embodiments of the present invention relate to the field of image processing, and in particular, to an image transmission system and an image transmission method. Background technique [0002] With the continuous improvement of the resolution of digital cameras, the amount of information contained in the photos taken by the cameras is becoming larger and larger, which poses challenges to storage and transmission. A common solution is to use image compression technology to use the spatial correlation between image pixels to remove redundant information and reduce image file size without damaging or slightly damaging image quality, so as to facilitate image storage and transmission. , Common image formats such as jpg and png are the embodiment of this kind of scheme. [0003] For the application scenario where the position and orientation of the camera are fixed and multiple photos taken at irregular intervals are transmitted to another electronic d...
