The drone may send the captured image to the control terminal through the wireless communication link, and the control terminal may receive the captured image sent by the drone.

S202. Control the terminal to obtain the watermark image;

The control terminal may acquire 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 text, numbers, identification numbers, and patterns. After acquiring the captured image, the control terminal may superimpose the watermark image into the captured image to generate a composite 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 acquiring the watermark image, the control terminal may also adjust at least one of the resolution, sharpness, specification, size, and transparency of the watermark image to obtain the adjusted watermark image, and use the adjusted The watermark image is superimposed on the captured image. Specifically, the watermark image acquired by the control terminal may be an image selected by the 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, to make the composite image more beautiful to form a good composition, before superimposing, it is necessary to adjust at least one of the resolution, sharpness, specifications, size and transparency of the watermark image, after obtaining the adjustment The watermark image, and then superimpose the adjusted watermark image on the captured image.

S302. The control terminal obtains a watermark image data packet from the server;

Wherein, when the control terminal needs to watermark the captured image, the control terminal can establish a communication connection with the server, and the control terminal can obtain the watermark image data package from the server, wherein the server can be a server of the drone manufacturer or copyright supervision Departmental server. The watermark image data packet is obtained by the server encrypting the initial watermark image using a preset encryption rule, and the initial watermark image is an image uploaded to the server by the user corresponding to the control terminal.

S303. The control terminal decrypts the watermark image data packet using a decryption rule to obtain a watermark image;

After acquiring the watermark image data packet, the control terminal may decrypt the watermark image data packet using a decryption rule, where the decryption rule corresponds to the encryption rule that the server encrypts the initial watermark image. When the decryption is successful, the control terminal can acquire the watermark image. When the decryption rule fails to decrypt the watermark image data packet, the control terminal may also output a prompt message to prompt the watermark image acquisition failure. It is understandable that the server encrypts the initial watermark image uploaded by the user by using the preset encryption rule is actually a process of authorization and authentication. Only the initial watermark image encrypted by the server can be controlled by the control terminal according to the The decryption rules corresponding to the encryption rules are decrypted to obtain the watermark image, otherwise the decryption fails and the watermark image cannot be obtained. In this way, the server can effectively manage the watermark image uploaded by the user, and at the same time ensure the transmission security of the watermark image. For example, in some cases, the server may determine whether the user activates the service of superimposing the watermark image on the captured image. When determining that the user activates the service, the server encrypts the initial watermark image uploaded by the user, otherwise the initial watermark image is not encrypted Encrypt.

Optionally, the control terminal decrypts the watermark image data packet using a decryption rule to obtain a watermark image, which may include: controlling the terminal to decrypt the watermark image data packet using a user's user information to obtain a watermark image. Specifically, the decryption rule corresponding to the preset encryption rule is a decryption rule determined according to user information, and the control terminal may use the user information to decrypt the watermark image data packet. In some cases, the preset encryption rule is an encryption rule determined according to user information, and the control terminal may use the user information to decrypt the watermark image data packet. The user information may include at least one of a user account, an identity mark, and a password corresponding to the user account.

In an optional embodiment, the control terminal may first upload an image to the server, and the server creates a watermark image data packet according to the image, so as to be sent to the control terminal, and the control terminal superimposes the watermark image on the captured image.

In one example, the control terminal obtains the image selected by the user and sends the image to the server as the initial watermark image corresponding to the user. In another example, the control terminal may acquire the image uploaded by the user and send the image to the server as the initial watermark image corresponding to the user.

S304. The control terminal superimposes the watermark image into the captured image to obtain a composite image.

At least one item of transparency is adjusted to obtain an adjusted initial watermark image; the server encrypts the adjusted initial watermark image according to a preset encryption rule to obtain a watermark image data packet. This embodiment can make the watermark image obtained subsequently superimposed on the captured image without affecting the normal display effect of the captured image.

In some cases, the server adjusts at least one of the resolution, sharpness, specifications, size, and transparency of the initial watermark image, which may include: the server automatically resolving the initial watermark image according to a preset rule Adjust at least one of rate, clarity, transparency, specifications, size, and transparency.
