Abstract

The invention discloses a moored unmanned aerial vehicle tracking system for automatic obstacle avoidance. The system includes a detection module, which is used to transmit detection signals and receive return signals; the measurement module is connected to the detection module to determine whether there is an obstacle above the road within the range of the current direction of travel, and if yes, further calculate the obstacle The shape characteristics of the outer contour of the object, and calculate the positional relationship between the obstacle and the current road based on the shape characteristics of the outer contour of the obstacle; the obstacle avoidance module is connected with the measurement device, the unmanned transport vehicle and the tethered drone respectively , to judge whether the current obstacle satisfies the avoidance condition based on the positional relationship, if yes, generate an obstacle avoidance control command, and the unmanned transport vehicle and the tethered UAV move according to the obstacle avoidance control command to avoid the obstacle. The invention can solve the problem of automatic obstacle avoidance of the tethered unmanned aerial vehicle system, expand the radius of free operation, and improve the response speed.

Description

technical field [0001] The invention relates to the technical field of a tethered UAV car-following system, in particular to a tethered UAV car-following system for automatic obstacle avoidance. Background technique [0002] The tethered UAV is a special form of multi-rotor UAV. It uses the ground advantage of the ground unmanned transport vehicle to transmit power to the UAV through the tethered cable, replacing the traditional on-board power supply. Prolonged hovering in the air provides a technical solution. The ground unmanned transport vehicle provides sustainable power supply and wired communication for the tethered drone through the tethered cable. The base station and RTK dual antennas are installed on the ground unmanned transport vehicle, and the RTK dual antennas are installed on the tethered UAV to provide mutual calibration of geographic coordinate information for the two, and at the same time realize the wireless data communication function. The main applicat...
