Problems solved by technology

The depth sensor is limited by the infrared ranging range, so it is not suitable for depth measurement in outdoor environments
[0004] In summary, the accuracy of the existing UAV tracking and shooting technology is low, and subject to environmental constraints, it is easy to fail to track

Abstract

The invention relates to a method and device for controlling UAV tracking and shooting, including: receiving a reference frame image of a target sent by a UAV, and calculating the pixel information of the target in the reference frame image; receiving the current frame of the target sent by the UAV image, and calculate the pixel information of the target in the current frame image; determine the direction to be adjusted according to the pixel information of the target in the reference frame image and the pixel information of the target in the current frame image; adjust the shooting attitude of the drone according to the direction to be adjusted . The method and device for controlling UAV tracking and shooting according to the embodiments of the present invention can maintain the relative distance between the UAV and the target during the UAV tracking and shooting, and ensure that the shooting target is in the center of the image, thereby improving The tracking accuracy and image quality of the UAV can avoid losing the target, simplify the human operation, and improve the user experience of aerial photography.

Description

technical field [0001] The invention relates to the technical field of shooting, in particular to a method and device for controlling a drone to track and shoot. Background technique [0002] UAV aerial photography uses unmanned aircraft as an aerial platform, with airborne remote sensing equipment, such as high-resolution CCD (Charge-Coupled Device, charge-coupled device) digital camera, light optical camera, infrared scanner, laser scanner , magnetic measuring instrument, etc. to obtain information, use a computer to process the image information, and make an image according to certain precision requirements. The whole system has outstanding features in terms of design and optimal combination. It is a new application technology that integrates high-altitude shooting, remote control, telemetry, microwave transmission of video images and computer image information processing. Technologies currently used for UAV tracking include GPS (Global Position System, Global Positionin...
