Visual tracking system for drone and control method thereof

Abstract

An embodiment of the invention provides a visual tracking system for a drone, and a control method thereof, wherein the system comprises the following parts: a three-axis stable pan / tilt, set on the drone and connected to a zoom camera; a main control module, configured to send camera parameters to the zoom camera such that the zoom camera captures an image according to camera parameters and outputs the captured image to the main control module, further receive an externally transmitted control command, and save the image according to the control command or send the image and configuration parameters to the image processing module; and an image processing module, configured to process the image sent by the main control module according to the configuration parameters, and return the processing result to the main control module; accordingly, the main control module is further configured to output control information to the three-axis stable pan / tilt according to the processing result sothat the three-axis stable platform controls the attitude of the zoom camera. The embodiment of the invention has the advantages of simple structure, high intelligence degree and convenient use.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of drones, and more specifically, to a visual tracking system for drones and a control method thereof. Background technique [0002] Modern drones are usually positioned as "flying smart cameras", and their core technologies also revolve around this purpose, mainly including autopilots, intelligent vision gimbals, and image transmission modules. Among them, the intelligent visual gimbal, as the core unit, has become a hot spot for competition among major drone manufacturers. [0003] In layman's terms, a smart gimbal is a three-axis stabilized gimbal that mounts a smart camera. In order to counteract the influence of body shaking or vibration, aerial photography gimbals usually need to stabilize the camera in the three axes of horizontal, roll, and pitch; in order to enable the drone to perform certain operations intelligently, it is necessary to use intelligent visual images The proc...

Problems solved by technology

In general, most of the existing visual pan / tilt products are designed and produced by drone companies, and their technical level in visual image processing still needs to be improved. The products are difficult to meet the increasingly rich visual application requirements of drones. Such as target multi-resolution shooting, target autonomous detection, etc.
