Problems solved by technology

In order to achieve follow-up shooting, the photographer needs to manually operate the gimbal or remotely control the gimbal to rotate. The gimbal cannot be controlled for automatic follow-up shooting based on the collected images. It is necessary to establish remote communication between the remote control device and the drone, which is likely to cause irrelevant information. interference, and the timeliness of manual operation is poor and the efficiency is low

Embodiment 1

[0029] An embodiment of the present invention provides a pan-tilt rotation control method, such as figure 1 As shown, the pan-tilt rotation control method includes:

[0030] Step S1: Obtain the image information captured by the image acquisition device mounted on the platform.

[0031] In practical applications, the image acquisition device may be at least one of a video camera, a camera, and an infrared thermal imager. In the embodiment of the present invention, a video camera is used to shoot video within a preset range. In a preferred embodiment, in order to reduce the calculation amount of subsequent identification and classification work, the image information collected by the camera can be preprocessed, and the preprocessing process can specifically include: scaling the collected image information, reducing the frame rate, and the like.

[0032] Step S2: Recognize the image information and acquire target detection information.

[0033] In the embodiment of the present...

Embodiment 2

[0062] An embodiment of the present invention provides a pan / tilt rotation control device, such as Figure 6 As shown, the pan / tilt rotation control device includes:

[0063] The image information acquisition module 1 is used to acquire the image information captured by the image acquisition device mounted on the platform. In practical applications, the image acquisition device may be at least one of a video camera, a camera, and an infrared thermal imager. The image information collection module 1 may correspondingly execute step S1 in Embodiment 1, which will not be repeated here.

[0064] The target detection information acquisition module 2 is used to identify image information and acquire target detection information. In the embodiment of the present invention, the video captured by the camera is recognized frame by frame to obtain the target detection information tuple of each identifiable target in the image. The identifying object module 2 may correspondingly execut...

Embodiment 3

[0070] An embodiment of the present invention provides a pan / tilt rotation control system, such as Figure 7 As shown, the pan-tilt rotation control system includes: an image acquisition module 10, an intelligent control module 20 and a pan-tilt module 30, wherein:

[0071] The image acquisition module 10 is used to acquire the image information captured by the image acquisition device mounted on the platform, and send the image information to the intelligent control module 20 . In the embodiment of the present invention, the image acquisition device may be at least one of a video camera, a camera, and an infrared thermal imager, and the image acquisition module 10 and the intelligent control module 20 are electrically connected. The image acquisition module 10 corresponds to the method of step S1 in Embodiment 1, which will not be repeated here.

[0072]The intelligent control module 20 is used to identify the image information and obtain target detection information; determ...

Abstract

The invention discloses a holder rotation control method and device, and an unmanned aerial vehicle. The method comprises steps that image information captured by an image capturing device mounted ona holder is acquired, and the image information is identified to acquire the target detection information; the position of a target object on the desired layout picture is determined based on the target detection information, and the adjustment action information of the holder is determined according to the position of the target object at the desired layout picture, the present angle of view of the image capturing device and the image information; the holder is adjusted to rotate according to the adjustment action information. The method is advantaged in that the acquired images are analyzedin the air, the holder can be automatically driven to take action according to preset requirements to achieve following shooting of the target object, establishing remote communication is not necessary, and accuracy of following shooting is higher.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a method and device for controlling the rotation of a pan-tilt and an unmanned aerial vehicle. Background technique [0002] With the development of science and technology and the improvement of people's living standards, the application prospect of aerial photography has become wider, including urban management, geological survey, meteorology, electric power and other fields. At the same time, with the reduction of the cost of drones and the popularization of photography technology, more and more people are exposed to aerial photography technology. [0003] In the prior art, during aerial photography, equipment such as cameras and video cameras are fixed in the cabin of the manned aircraft or the outside of the unmanned aerial vehicle through the platform. In order to achieve follow-up shooting, the photographer needs to manually operate the gimbal or remotely control the gimba...
