Problems solved by technology

[0004] However, when the user performs image zoom processing, he actually only pays attention to the display content of a part of the image, so that when the UAV returns the complete captured image, most of the returned data will be lost. Not being noticed by users, resulting in a waste of communication resources, and may also cause display freezes and delays on the remote control device due to excessive data volume

Abstract

The invention relates to an image transmission method and device and an electronic device. The method may comprise the steps of when image collection is carried out through a camera module assembled on an unmanned aerial vehicle, obtaining an image processing instruction sent by a user through a remote control device of the unmanned aerial vehicle, wherein the image processing instruction comprises an image scaling parameter; determining an image area corresponding to the image scaling parameter in the collected image of the camera module; resampling the image data corresponding to the image area in the collected image according to the screen resolution of the remote control device; and transmitting a resampling image obtained through resampling back to the remote control device, thereby displaying the resampling image on a screen of the remote control device. Through application of the technical scheme of the invention, the image display focal length adjustment can be realized on the remote control device, the data transmission quantity of the image is reduced, the delay is reduced, and the image display fluency on the remote control device is improved.

Description

technical field [0001] The present disclosure relates to the technical field of drones, and in particular to an image transmission method and device, and electronic equipment. Background technique [0002] UAVs have been widely used in various application scenarios and technical fields such as aerial photography, exploration, and rescue. Image acquisition is performed through the camera module assembled on the drone, and image transmission is performed between the communication module assembled on the drone and the remote control device used by the user, so that the user can view the drone on the screen of the remote control device Returns the captured image. [0003] The camera modules assembled on the unmanned aerial vehicles in the related art all use fixed-focus lenses, so that users cannot zoom in and view a part of the captured image by adjusting the focal length of the lens. To this end, the UAV needs to fully return the captured image to the remote control device, ...
