Method and system for UAV visual landing based on 5G network

Abstract

The invention discloses a 5G network-based UAV visual landing method and system. The steps of the method are: the ground terminal system sends a landing control signal to the UAV; the UAV collects images through a high-definition camera, The terminal 5G network communication module transmits to the ground terminal system, the visual navigation module performs image recognition, and performs image grayscale processing and image edge detection on the collected images. When a landing beacon is detected, the visual navigation module calculates the UAV and landing signal The relative position of the target; the main control module of the drone adjusts the position of the drone until the optical center of the high-definition camera coincides with the center of the landing beacon; When the distance between the man-machine and the landing beacon is less than the set value, the drone will stop and complete the landing. The invention completes the precise landing of the UAV, performs signal transmission based on the 5G network, and realizes ultra-high-definition real-time video transmission of the UAV.

Description

technical field [0001] The invention relates to the technical field of UAV visual navigation, in particular to a 5G network-based UAV visual landing method and system. Background technique [0002] With the rapid development of the drone industry, the application of drones involves many industries, and there are many ways to control drones. The most common ones are manual remote control and ground station control. These two control methods are used in There are certain defects in controlling the UAV to land. When the UAV is landed manually, the UAV may be damaged due to improper operation; when the ground station controls the landing, the UAV cannot complete the precise landing due to positioning errors. On the other hand, most of the existing UAV visual landing methods use Wifi for image transmission, sometimes the image transmission is delayed due to signal reasons, and the transmission distance is also greatly limited.
