The unmanned aerial vehicle can send the shot image to the control terminal through the wireless communication link, and the control terminal can receive the shot image sent by the unmanned aerial vehicle.
S202, the control terminal obtains a watermark image;
the control terminal may obtain a watermark image, where the watermark image may be an image selected by a user of the control terminal, where the image may include one or more of characters, numbers, identification numbers, and patterns. The control terminal may superimpose the watermark image on the photographed image to generate a composite image after acquiring the photographed image.
Optionally, the watermark image may be an image stored in a local storage device, or an image uploaded by a user through a control terminal.
Optionally, after the control terminal obtains the watermark image, at least one of resolution, definition, specification, size, and transparency of the watermark image may be adjusted to obtain an adjusted watermark image, and the adjusted watermark image is superimposed on the captured image. Specifically, the watermark image acquired by the control terminal may be an image selected by a user, for example, an image uploaded by the user through the control terminal; optionally, the watermark image is an image stored in a local storage device. In some cases, the composite image is more beautiful to form a good composition, and at least one of resolution, definition, specification, size, and transparency of the watermark image needs to be adjusted before the superposition to obtain an adjusted watermark image, and then the adjusted watermark image is superposed into the photographed image.

Specifically, the control terminal may determine the size of the captured image, for example, the length and width of the captured image are L and H, respectively, and the control terminal may determine the target position of the watermark image in the captured image according to the length and width of the captured image, for example, the target position is one fourth H away from the lower boundary of the captured image and one fifth L away from the left boundary of the captured image.
Specifically, the determining, by the control terminal, the target position where the watermark image is superimposed on the captured image according to the color information of the captured image may include: and determining an image area in which the color information of the shot image and the color information of the watermark image meet a preset relationship, and determining the target position according to the image area. For example, the control terminal may determine an image area in the captured image where the contrast between the color information and the color information of the watermark image is the greatest, that is, determine which image area in the captured image has the greatest contrast between the color information and the color information of the watermark image, the control terminal may set the center of the image area as a target position, and the control terminal superimposes the watermark image on the target position in the captured image, so that the display of the watermark image in the composite image is more striking, and the display effect is better.

For another example, the control terminal may invoke a social application program, for example, a text-based social application program such as a WeChat or a microblog, or a device of a live broadcast platform or a relay broadcast platform such as a live broadcast mini-video.
In summary, the embodiment of the present invention can obtain the captured image output by the capturing device configured by the unmanned aerial vehicle from the unmanned aerial vehicle, and directly superimpose the watermark image on the captured image to obtain the composite image, thereby avoiding the problem that the control terminal needs to send the captured image to other image processing terminals for adding the watermark, being beneficial to avoiding the problem that the captured image is stolen and stolen, and simplifying the operation flow of adding the watermark.
Referring to fig. 3, fig. 3 is an interactive flow chart of another captured image processing method according to an embodiment of the present invention. In the shot image processing method shown in fig. 3, the watermark image may be acquired from a server, and specifically, as shown in fig. 3, the shot image processing method may include the following steps:

s302, the control terminal acquires a watermark image data packet from the server;
when the control terminal needs to watermark the shot image, the control terminal can establish communication connection with the server, and the control terminal can acquire the watermark image data packet from the server, wherein the server can be a server of an unmanned aerial vehicle manufacturer or a server of a copyright supervision department. The watermark image data packet is obtained by encrypting an initial watermark image by the server according to a preset encryption rule, wherein the initial watermark image is an image uploaded to the server by a user corresponding to the control terminal.
S303, the control terminal decrypts the watermark image data packet by using a decryption rule to obtain a watermark image;
after the control terminal acquires the watermark image data packet, the control terminal can decrypt the watermark image data packet by using a decryption rule, wherein the decryption rule corresponds to an encryption rule of the initial watermark image encrypted by the server. When the decryption is successful, the control terminal can acquire the watermark image. When the control terminal fails to decrypt the watermark image data packet by using the decryption rule, prompt information can be output to prompt that the watermark image acquisition fails. It can be understood that the encryption of the initial watermark image uploaded by the user by the server by using the preset encryption rule is actually an authorization and authentication process, only the initial watermark image encrypted by the server can be decrypted by the control terminal according to the decryption rule corresponding to the encryption rule to obtain the watermark image, otherwise, the decryption fails, and the watermark image cannot be obtained. By the method, the server can effectively manage the watermark image uploaded by the user, and meanwhile, the transmission safety of the watermark image is ensured. For example, in some cases, the server may determine whether the user opens a service for capturing an image superimposed with a watermark image, and when it is determined that the user opens the service, the server encrypts an initial watermark image uploaded by the user, and otherwise, the initial watermark image is not encrypted.
Optionally, the controlling terminal decrypts the watermark image data packet by using the decryption rule to obtain the watermark image, and may include: and the control terminal decrypts the watermark image data packet by using the user information of the user to obtain the watermark image. Specifically, the decryption rule corresponding to the preset encryption rule is a decryption rule determined according to the user information, and the control terminal may decrypt the watermark image data packet by using the user information. In some cases, the preset encryption rule is an encryption rule determined according to user information, and the control terminal may decrypt the watermark image data packet by using the user information. The user information may include at least one of a user account, an identity, and a password corresponding to the user account.
In an alternative embodiment, the control terminal may upload an image to the server, and the server creates a watermark image data packet according to the image so as to send the watermark image data packet to the control terminal, and the control terminal superimposes the watermark image on the shot image.
In one example, the control terminal acquires an image selected by a user and sends the image to the server as an initial watermark image corresponding to the user. In another example, the control terminal may obtain an image uploaded by a user and transmit the image to the server as an initial watermark image corresponding to the user.
S304, the control terminal superimposes the watermark image on the shot image to obtain a composite image.
Step S304 is the same as step S203, and specific descriptions may refer to the related descriptions of the above embodiments, and are not described in detail here.
Therefore, the watermark image acquired by the control terminal is acquired by decrypting the watermark image data packet acquired by the server by using the decryption rule, so that the control terminal can be ensured to directly add the watermark image into the shot image, and the encrypted watermark image authorized by the server can be used for superposition processing, thereby ensuring the legality and safety of the added watermark image and further avoiding the situation that the image shot by the unmanned aerial vehicle is illegally used.

The watermark image data packet is used for decrypting the watermark image data packet by using a decryption rule corresponding to the encryption rule through the control terminal to obtain a watermark image, and the watermark image is superposed into a shot image. The captured image is acquired from the drone and is output by a camera configured with the drone.
In an optional implementation manner, the encrypting, by the server, the initial watermark image according to a preset encryption rule to obtain a watermark image data packet includes: and encrypting the initial watermark image according to the user information of the user to obtain a watermark image data packet. For example, the initial watermark image is encrypted by using the user name of the user, and an encrypted watermark image data packet is obtained.
In an optional implementation manner, before encrypting the watermark image according to a preset encryption rule to obtain a watermark image data packet, the server may further adjust at least one of resolution, definition, specification, size, and transparency of the initial watermark image to obtain an adjusted initial watermark image; and the server encrypts the adjusted initial watermark image according to a preset encryption rule to obtain a watermark image data packet. According to the embodiment, the watermark image obtained subsequently can be superposed on the shot image, and the normal display effect of the shot image cannot be influenced.
In some cases, the server adjusting at least one of resolution, sharpness, size, dimension, and transparency of the original watermark image may include: and the server automatically adjusts at least one of the resolution, the definition, the transparency, the specification, the size and the transparency of the initial watermark image according to preset rules.
