Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0041] It should be noted that, in the case of no conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0042] Traditional wireless image transmission abnormal recovery methods are usually based on image information analysis, specifically based on optical flow to estimate the motion information of objects in the image, and then match the errors or absences in the current image from historical images based on the image segmen...

Abstract

The invention discloses an image transmission system and method, a control device and a movable platform. The image transmission system comprises the movable platform (100) and the control device (200) in communication connection with the movable platform. The movable platform is used for sending an image acquired by the movable platform and motion information of the movable platform during imageacquisition to the control device; and if an abnormal area exists in the image received by the control device at the current moment, the control device is used for filling the abnormal area accordingto the image received at the previous moment and the motion information of the movable platform corresponding to the image received at the previous moment, and the abnormal area comprises a pixel information missing area or a pixel information error area. According to the invention, the abnormal area in the image received at the current moment is filled through the image received at the previous moment and the motion information of the movable platform corresponding to the image received at the previous moment, and the effect and reliability of wireless image transmission abnormality recoverycan be improved.

Description

technical field [0001] The present application relates to the field of image transmission, in particular to an image transmission system and method, a control device, and a movable platform. Background technique [0002] When remotely controlling the movable platform, the user needs to obtain images collected by the movable platform to operate the control device according to the image returned by the movable platform, so as to realize safe manipulation of the movable platform. Usually, the movable platform will transmit the images it collects to the control device through wireless transmission. However, in the process of wireless image transmission, due to the influence of unfavorable conditions such as wireless signal interference, occlusion on the transmission path, too long transmission distance, and antenna pointing deviation, it may cause problems such as interruption, blurred screen, and mosaic, which greatly affect the remote image. Control experience may also cause ...
