The following description will be made with reference to example five and example six.
EXAMPLE five
Referring to fig. 5, fig. 5 is a flowchart of an information processing method disclosed in the fifth embodiment of the present invention. The information processing method is applied to the server. The information processing method includes:
step S51: and receiving a first video stream and a second video stream transmitted by the electronic equipment.
The first video stream is formed by collecting images in real time by a first camera of first electronic equipment, the second video stream is formed by collecting images simultaneously by a second camera of the first electronic equipment, the first video stream comprises images of a user, and the second video stream comprises images of a scene where the user is located.

Step S54: biometric information of the user is obtained based on the M frames of the first image.
Step S55: and judging whether the biological characteristic information meets a preset condition for representing the attention of the user.
When the biological characteristic information of the user meets a preset condition for representing the attention degree of the user, the fact that the attention point of the user is contained in the N frames of second images is indicated. For example: the N-frame second image includes an image of a building focused by the user, an image of a brand car focused by the user, an image of a person focused by the user, an image of a work focused by the user, and the like.
The biometric information of the user includes facial expression information of the user, limb information of the user, and voice information of the user. The predetermined conditions characterizing the user's attention include, but are not limited to: 1. the voice information of the user includes a specific word, for example, the voice information of the user includes a word indicating the actions of others, such as "quick look", or a language word such as "o"; 2. the volume or pitch of the user's voice reaches a predetermined value; 3. the limb information of the user includes specific limb information, for example, a limb movement of the user to move a finger in a certain direction, a limb movement of the user to shake the arm, a limb movement of the user to cheer and jump, or a limb movement of the user to watch the same area for a long time; 4. the facial expression information of the user includes specific facial expression information.
Step S56: when the biological feature information satisfies a predetermined condition for characterizing the user attention, object information of an object contained in the N frames of second images is obtained through image analysis.
The object information of the object contained in the second image can be an image of an object in the second image, such as an image of a building, an image of a person, or an image of L ogo (logo).
Step S57: data content associated with the object information is obtained as a result of the processing.
The server searches by using the obtained object information to obtain the data content related to the object information. The data content may be a text introduction to the object or image information associated with the object.
Step S58: and sending the processing result to the electronic equipment.
This is illustrated with reference to an example. Two opposite sides of the electronic equipment are respectively provided with a first camera and a second camera. The user starts the first camera and the second camera to shoot, wherein the first camera faces to the user, under the condition, the first camera collects images in real time to generate a first video stream containing user images, and meanwhile, the second camera collects images in real time to generate a second video stream containing scenes where the user is located. The electronic device transmits the first video stream and the second video stream to the server in real time.
The server extracts a first image from the first video stream according to a preset time interval, and correspondingly extracts a second image from the second video stream. The server analyzes the first image, obtains the biological feature information of the user, analyzes the extracted second image when the biological feature information of the user meets a preset condition for representing the attention degree of the user (for example, the user watches a certain area for a long time), obtains the image of the vehicle contained in the second image, then searches based on the image of the vehicle, obtains the word introduction of the vehicle or the related image of the vehicle of the model as a processing result, and transmits the processing result to the electronic equipment.
And after receiving the processing result transmitted by the server, the electronic equipment displays the processing result through a display device of the electronic equipment.
And if the electronic equipment is a mobile phone, displaying the received processing result on a display screen by the mobile phone.
If the electronic device is an AR device (enhanced display device), the AR device adjusts the display effect of a specific area of the display screen after receiving the processing result transmitted by the server, and displays the processing result in the specific area. The user is able to see the real vehicle through the display screen of the AR device while seeing the processing results displayed in a particular area of the display screen.
If the electronic equipment is VR equipment (virtual display equipment), the VR equipment receives the processing result transmitted by the server and then displays the received processing result and the current virtual image simultaneously through the display screen. It should be noted here that the current virtual image of the VR device may be: and the virtual image is formed after the image shot by the second camera is subjected to virtual processing.
