Problems solved by technology

In this way, it is impossible to determine in real time whether the images acquired by the UAV during the flight are overexposed, too dark, or the field of view. effect, you need to reset the drone's aerial photography and mapping parameters, and fly again
This is inconvenient and wasteful

Embodiment 1

[0103] image 3 It is a schematic flowchart of an image transmission method provided by an embodiment of the present invention. The image transmission method in the embodiment of the present invention can be implemented by cooperation of various components in the above-mentioned unmanned aerial vehicle, which is not limited here.

[0104] see image 3 , the image transmission method includes:

[0105] 301: Get the original image.

[0106] During the flight of the unmanned aerial vehicle, the original image may be collected by the image acquisition device to obtain the original image. Wherein, the image acquisition device may be an image acquisition device such as a camera or a video camera. Moreover, in order to improve the quality of the original image collected, a camera with a larger image sensor size, such as a full-frame camera or a medium-frame camera, can be used to obtain original images with high image quality such as a full-frame or medium-frame image.

Embodiment 2

[0123] Figure 4 It is a schematic flowchart of another image transmission method provided by an embodiment of the present invention. The image transmission method in the embodiment of the present invention can be implemented by cooperation of various components in the above-mentioned unmanned aerial vehicle, which is not limited here.

[0124] see Figure 4 , the image transmission method includes:

[0125] 401: Get the original image.

[0126] 402: Store the original image.

[0127] In order to call the original image later when needed, the acquired original image can be stored in the built-in or external storage space of the UAV. For example, the unmanned aerial vehicle is provided with an external SD card interface, and memory devices such as SD cards can be inserted into the interface to store the acquired original images. Moreover, several frames of continuous original images form a video or video, and in some instances, the video or video formed by several frames o...

Embodiment 3

[0183] Figure 7 It is a schematic diagram of an image transmission device provided by an embodiment of the present invention. Wherein, the image transmission device 70 can be configured in the above-mentioned unmanned aerial vehicle.

[0184] refer to Figure 7 , the image transmission device 70 includes: an acquisition module 701, a storage module 702, a compression module 703, a first conversion module 704, a second conversion module 705, a statistical module 706, a detection module 707, an encoding module 708, a transmission module 709 and discarding Module 710.

[0185] Specifically, the obtaining module 701 is used to obtain the original image.

[0186] The acquisition module 701 may be connected with the image acquisition device, and during the flight of the UAV, the acquisition module 701 may acquire the original image through the image acquisition device to obtain the original image. Wherein, the image acquisition device may be an image acquisition device such as ...

Abstract

The embodiment of the invention relates to the technical field of aircraft, and discloses an image transmission method, a device, an image sending end and an aircraft graphic transmission system. Themethod comprises the following steps of: acquiring an original image; Converting the original image into a first image, the first image being an image conforming to an audio-video interface format; Converting the first image into a second image, the second image being an image conforming to an image receiving end interface format; Encoding the second image to obtain an encoded image; and transmitting the encoded image to the image receiving terminal. The image transmission method provided by the embodiment of the invention realizes the real-time transmission of the image.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of aircraft, and in particular to an image transmission method, an image transmission device, an image sending end, and an aircraft image transmission system. Background technique [0002] With the development of flight technology, drones and other aircraft have received more and more attention. As a popular shooting vehicle, drones can obtain many shooting angles that cannot be achieved by normal photography due to their high mobility, fast response and flexible position movement, which makes drones popular More and more applications in aerial surveying and mapping. [0003] For the current application of UAVs in aerial photography and mapping, the aerial photography and mapping parameters are usually set before the UAV takes off. In the space, files such as photos, videos or videos are formed. After the drone completes the flight mission of aerial photography and mapping, the us...
