Problems solved by technology

[0003] However, in aerial photography applications, the flying distance of the UAV has exceeded the remote control distance of the existing focus system, and as the distance becomes longer, the communication delay between the handheld remote control terminal and the motor receiving terminal of the focus system will be greatly increased. And there is a freeze, which makes it impossible to directly apply the existing focus system to the field of drone aerial photography

Abstract

An aerial photography follow-focus control system, comprising a follow-focus remote controller (3) for generating follow-focus control commands, the aerial photography follow-focus control system further comprising: an aircraft remote controller (4), the aircraft remote controller (4) Communicatively connected with the follow-focus remote controller (3) to receive the follow-focus control instruction transmitted by the follow-focus remote controller (3); the air terminal communication unit (18) is used to communicate with the aircraft remote controller (4 ) communication connection to receive the focus control instruction from the aircraft remote controller (4); and a control system for controlling the focus motor according to the focus control instruction received by the air terminal communication unit (18) (24) Driving the lens of the photographing device (23) to rotate. The invention also provides an aerial photography follow-focus method and an aircraft (1).

Description

technical field [0001] The present invention relates to an aerial photography follow-focus control system and method, in particular to an aerial photography follow-focus control system and method based on an unmanned aerial vehicle, and an aircraft using the method. Background technique [0002] The existing follow focus system generally includes a handheld remote control terminal and a motor receiving terminal. After the handheld remote control terminal obtains the rotation position of the handle, it sends instructions to the motor receiving terminal through the radio frequency module, and the motor receiving terminal controls the rotation of the motor after receiving the command, thereby Drive the camera lens to rotate to realize the change of lens focal length or aperture. The existing focus system and the remote control and receiving system of the UAV are independent of each other. [0003] However, in aerial photography applications, the flying distance of the UAV has ...
