Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] At present, the existing tests for the UAV navigation system require testers to test the real machine equipped with the UAV visual navigation system. The results of the navigation test are easily interfered by other parts of the system, and the test The identifiability of the characteristic target is poor, resulting in a large error in the test results. At the same time, the t...

Abstract

The invention provides a UAV visual navigation testing method and system, and relates to the technical field of UAV navigation assisting equipment. The system comprises an infrared parking apron device, a handheld testing device, a flying controller and a host computer, wherein the handheld testing device comprises a target data acquiring module, a main controller, a wireless communication moduleand a power supply; the target data acquiring module is used for acquiring and generating target image information and sending the target image information; the main controller is used for receiving the target image information and generating the target location information based on the target image information; the flying controller is used for receiving the target location information and generating navigation information based on the target location information; the main controller is used for sending the target image information and the navigation information to the host computer through the wireless communication module. According to the technical scheme, the system has the advantages that the technical problems of high testing difficulty and low testing accuracy of an UAV navigationsystem can be decreased; the testing process is simplified while the testing accuracy of the UAV navigation system is ensured.

Description

technical field [0001] The invention relates to the technical field of UAV navigation auxiliary detection equipment, in particular to a UAV visual navigation testing method and system. Background technique [0002] Rotor UAV has been widely developed and applied in civil and military fields because of its high flexibility and low take-off and landing conditions. Classic rotorcraft UAVs, such as multi-rotor UAVs, single-rotor unmanned helicopters and coaxial counter-rotating unmanned helicopters, play an important role in solving environmental monitoring, marine pollution monitoring, and geographic information collection. [0003] UAV navigation refers to the method or process of determining the position and direction of UAV during flight, involving mechanics, electronics, automatic control and computer and other disciplines. The performance of the navigation system is directly related to the completion of the navigation task. The UAV relies on the flight control system to r...
