Embodiment 1

[0045] see figure 1 , propose the aerial photography method of the first embodiment of the present invention, described method comprises the following steps:

[0046] S11. Collect images through two cameras.

[0047] In the embodiment of the present invention, the drone is provided with two cameras to form a group of binocular cameras. The two cameras are preferably arranged side by side. Of course, it can also be set in a staggered manner, that is, the two cameras are not on the same horizontal line. There is a certain distance between the two cameras. In theory, the larger the distance, the better.

[0048] In this step S11, the UAV collects images simultaneously (synchronously) through two cameras, and the collected images may be photos or video streams.

[0049] S12. Stitch the two images collected by the two cameras into one 3D image.

[0050] Specifically, the two images collected by the two cameras are spliced ​​side by side, preferably, the images collected by the...

Embodiment 2

[0071] see figure 2 , propose the aerial photography method of the second embodiment of the present invention, described method comprises the following steps:

[0072] S21. Collect video streams through two cameras arranged side by side.

[0073] In this embodiment, the binocular cameras of the UAV are arranged side by side, and the UAV simultaneously collects video streams through the binocular cameras.

[0074] S22. Sampling the two video streams collected by the two cameras respectively into two video streams with preset resolutions.

[0075] S23. Splice two video streams with preset resolution side by side side by side to obtain a 3D video stream in left and right format.

[0076] Specifically, the UAV first samples the two video streams collected by the binocular camera into two video streams with preset resolutions, and then stitches the two video streams with preset resolutions side by side. Preferably, The video streams collected by the left camera are spliced ​​on...

Embodiment 3

[0088] see image 3 , the aerial photographing device of the third embodiment of the present invention is proposed, the device includes an image acquisition module, an image processing module and an image sending module, wherein:

[0089] Image acquisition module: used to acquire images through two cameras.

[0090] In the embodiment of the present invention, the drone is provided with two cameras to form a group of binocular cameras. The two cameras are preferably arranged side by side. Of course, it can also be set in a staggered manner, that is, the two cameras are not on the same horizontal line. There is a certain distance between the two cameras. In theory, the larger the distance, the better.

[0091] The image acquisition module simultaneously (synchronously) acquires images through two cameras, and the acquired images can be photos or video streams.

[0092] Image processing module: used to stitch two images collected by two cameras into one 3D image.

[0093] Sp...

Abstract

The invention discloses an aerial photographing method, device and an unmanned aerial vehicle. The method comprises the following steps: acquiring images through two cameras; splicing the two images acquired by the two cameras into one 3D image; and sending the 3D image out. Thus, the unmanned aerial vehicle can provide the 3D image in the process of aerial photographing, and users are allowed to view the 3D image with the lifelike picture in real time, thereby bringing the immersive experience to the users, and greatly enhancing the aerial photographing experience of the users. Further, when the 3D image is transmitted to the users for viewing in real time, depth detection is carried out through the 3D image, so that the unmanned aerial vehicle can realize multiple functions, such as 3D aerial photographing, obstacle avoidance, tracking, ranging and so on by using a group of binocular cameras (that is two cameras), thus 3D photographing and depth detection can be respectively realized without respectively using the two groups of binocular cameras (that is four cameras), and multiple functions can be achieved at a lower cost.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an aerial photography method, device and unmanned aerial vehicle. Background technique [0002] With the rapid development of UAV technology, the application of UAV is more and more extensive, among which aerial photography is a relatively important application field. The current aerial photography system is mainly composed of a drone and a remote control device. The user controls the drone through the remote control device, and the drone transmits the captured image to the remote control device in real time through an aerial camera for viewing by the user. [0003] In order to provide users with a more realistic experience, head-mounted virtual reality (Virtual Reality, VR) devices such as VR glasses are used as remote control devices in the prior art. The drone transmits the captured images to the VR glasses in real time, and the user watches the captured imag...
