Fig. 1 is a schematic diagram of a video processing method according to an embodiment of the present invention. As shown in fig. 1, the video processing method includes:

step 101: acquiring a video stream;

step 102: identifying at least two-dimension code business cards contained in a video stream to obtain a user identifier corresponding to each two-dimension code business card in the at least two-dimension code business cards;

step 103: and processing the user identification corresponding to each two-dimensional code business card.

According to the video processing method provided by the embodiment of the invention, the user identification corresponding to each two-dimension code business card in the at least two-dimension code business cards is obtained by identifying the at least two-dimension code business cards contained in the obtained video stream; and then, processing the user identification corresponding to each two-dimension code business card, thereby simplifying the operation of identifying a plurality of two-dimension codes.

In this embodiment of the present invention, a video stream is a video stream including a plurality of two-dimensional code business cards, for example, the plurality of two-dimensional code business cards are two-dimensional code business cards displayed on a plurality of terminals, or two-dimensional code business cards displayed on paper, and the obtaining 101 of a video stream includes:

and acquiring a video stream recorded by the current terminal equipment, wherein the video stream comprises two-dimensional code business cards displayed on at least two pieces of terminal equipment.

Correspondingly, in this example, acquiring the video stream recorded by the current terminal device includes:

and acquiring the video stream through a camera of the current terminal equipment or through a scanning function of instant messaging software. The current terminal device is a terminal device corresponding to an initiator for adding the group member in the at least two terminal devices, and the at least two terminal devices except the current terminal device are terminal devices corresponding to the added group member.

In some embodiments of the present invention, the acquiring a video stream in step 101 includes:

and scanning the two-dimensional code business card displayed on each of the at least two terminal devices, and recording the video stream.

Specifically, before the two-dimension code business card is identified, each member can call the two-dimension code business card of the user in the instant messaging software, and one member of all the members starts the terminal device to record the two-dimension code business cards of other users, so that a two-dimension code video stream is obtained.

In some embodiments of the present invention, before identifying at least two-dimensional code business cards contained in the video stream, the method comprises:

The user identifier is not limited to include a user account and a user image.

According to the embodiment of the invention, each frame of image in the video stream does not need to be identified, and only the image containing the two-dimensional code business card is identified, so that the identification speed is increased, and the user experience degree is improved.

Wherein, whether the image contains the two-dimensional code business card in the detection video stream includes:

and extracting the images in the video stream frame by frame or frame by frame, and detecting the extracted images to determine whether the images contain the two-dimensional code business cards. Wherein the sampling frequency may be 0.5.

a processor 501 configured to:

and receiving group member adding confirmation information returned by the terminal equipment corresponding to the two-dimensional code business card, and adding the group members according to the confirmation information.

Optionally, the processor 501 is further configured to detect whether an image in the video stream contains a two-dimensional code business card; and in the case that the image in the video stream contains the two-dimension code business card, identifying the two-dimension code business card contained in the image in the video stream.

Optionally, the processor 501 is further configured to extract a plurality of images in the video stream at intervals of frames;

and identifying all two-dimensional code business cards contained in the video stream according to the extracted plurality of images.

Optionally, the processor 501 is further configured to:

creating a chat group based on the user identification corresponding to each two-dimensional code name card;

and adding the user identification corresponding to each two-dimensional code business card as a group member in the chat group.
