Problems solved by technology

[0003] The manipulation of these moving bodies is usually realized by the user through a remote control device. When the operator is operating a moving body, such as an unmanned aerial vehicle, since the unmanned aerial vehicle is generally small in size, it is difficult to see clearly with the naked eye when flying far away. , in this case, it is difficult for the operator to observe the actual flight distance of the UAV. If there is no auxiliary means of flight, the UAV will easily miss
In addition, if you use the first-person perspective mode to fly, if you focus too much on the display screen, you may not know the current position of the UAV in the end, resulting in disorientation or even flying loss. quality

Embodiment Construction

[0037] The camera processing method of the unmanned aerial vehicle disclosed by the present invention comprises the steps of:

[0038] Aim the UAV camera at the target;

[0039] Focus on the target object for the first time, and record the image information of the focus frame as the first reference pattern;

[0040] The unmanned aerial vehicle automatically moves the preset distance, focuses on the target object for the second time, and records the image information of the focusing frame as the second reference pattern;

[0041] synthesizing a stereoscopic reference pattern of the target object according to the first reference pattern and the second reference pattern;

[0042] When the unmanned aerial vehicle detects that the control signal is interrupted, the focus frame will automatically traverse the images in the entire viewfinder frame and compare them with the stereo reference pattern respectively. If no target object is found, the position of the unmanned aerial vehicl...

Abstract

The invention discloses a camera processing method for an unmanned aerial vehicle. The method includes the steps of: aligning the camera of the unmanned aerial vehicle with the target object; recording the first reference pattern; recording the second reference pattern; synthesizing the three-dimensional reference pattern of the target object; when the unmanned aerial vehicle detects that the control signal is interrupted, the focus frame automatically Traverse the images in the entire viewfinder frame and compare them with the stereo reference pattern respectively. If the target object is not found, automatically adjust the position of the UAV until the target object is redisplayed in the cameras viewfinder frame; preset a distance between the camera and the target object the reference line, control the UAV to move along the reference line; calculate the measurement distance between the camera and the target; if the measurement distance is greater than the preset reference distance, control the UAV to continue to move towards the target until the measurement distance is less than or equal to the reference distance. The invention can improve the shooting quality when the unmanned aerial vehicle is flying and lost.

Description

technical field [0001] The present invention relates to the field of aerial photography, and more specifically, relates to a camera processing method for an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicles are widely used in aerial photography, detection, search and rescue and other fields. [0003] The manipulation of these moving bodies is usually realized by the user through a remote control device. When the operator is operating a moving body, such as an unmanned aerial vehicle, since the unmanned aerial vehicle is generally small in size, it is difficult to see clearly with the naked eye when flying far away. , In this case, it is difficult for the operator to observe the actual flight distance of the UAV. If there is no auxiliary means of flight, the UAV will be easily lost. In addition, if you use the first-person perspective mode to fly, if you focus too much on the display screen, you may not know the current position of the UAV in th...
