Detailed Description
Before the technical scheme of the application is introduced, a screen projection method in the related art is introduced:
when a user needs to screen multimedia information in an intelligent terminal such as a mobile phone on a television for display or playing, the user usually searches out names of all televisions accessed to a local area network through related software in the mobile phone, and the user selects a target television based on the names of all televisions displayed by the mobile phone to trigger the mobile phone to establish screen-casting connection with the target television, so that the multimedia information in the mobile phone is screened to the target television.
Because the names of televisions produced by the same manufacturer when leaving the factory are the same, when a user searches at least two televisions with the same or similar names in the same local area network through a mobile phone, the names of the televisions are usually manually modified through a system setting interface of the televisions to distinguish, for example, the names are changed into 'living room televisions' and 'master room televisions', the operation is complicated, the old people or people with poor learning ability are difficult to complete, and the user cannot quickly identify the television to be screened, so that the screen casting efficiency is influenced.
In order to solve the above technical problem, the present application provides a method for identifying an electronic device, which sends a first request to each of at least one first electronic device searched in a wireless local area network; and displaying all acquired screen capture images under the condition that the screen capture image sent by at least one first electronic device based on the first request is acquired. The user identifies the target electronic equipment from the searched at least one electronic equipment based on the displayed screen capture image, so that the target electronic equipment can be quickly and accurately identified, and the efficiency and the accuracy of identifying the target electronic equipment are improved.
The technical solution of the present application is further described in detail with reference to the drawings and specific embodiments of the specification.

Here, the screen capture image and the random information displayed by the second electronic device are independent of each other, so that even if there is a screen capture image with the same screen in the screen capture image displayed by the second electronic device and the random information is not included in the screen capture image or the random information in the screen capture image cannot be seen clearly by the user, the user can quickly and accurately identify the target electronic device based on the random information displayed in association with the screen capture image and the random information displayed by the first electronic device.
In practical application, when the first electronic device is an intelligent television, under a scene that different intelligent televisions play the same program, program contents in screenshot images sent by the intelligent television received by the second electronic device may be the same, and a user cannot distinguish different intelligent televisions through the screenshot images; when the second electronic device displays the thumbnail of the screenshot image or the size of the random information is small, even if the random information is included in the screenshot image, the user may not see the random information in the screenshot image, and at this time, the user may distinguish different smart televisions through the random information displayed in association with the screenshot image, so that the target smart television is identified.
In some embodiments, the method may further include S308: and the second electronic equipment is projected to the target electronic equipment selected by the user.

Therefore, before the screen capture image sent by the first electronic device is acquired by the first electronic device, the user can view the display setting image of the second electronic device, so that the user can know the processing progress, and the user can be prevented from mistakenly considering that the fault occurs in the process of acquiring the screen capture image of the first electronic device by the second electronic device; under the condition that the second electronic equipment displays the equipment identifier of the first electronic equipment and the set image in an associated manner, a user can preliminarily screen out the first electronic equipment which needs to be connected with the second electronic equipment based on the equipment identifier of the first electronic equipment, and then accurately determine target electronic equipment based on a screen capture image sent by the first electronic equipment; when at least two device identifications are the same or close to each other in the displayed device identifications, the target electronic device can be quickly determined based on the screen capture image sent by the first electronic device.
When the screenshot image sent by the first electronic device comprises the random information, even if the screenshot image displayed by the second electronic device has the screenshot image with the same picture, the user can quickly identify the target electronic device based on the random information sent by the first electronic device and the random information displayed by the first electronic device, and the efficiency of identifying the target electronic device is improved.
The second electronic equipment displays the screen capture information sent by the first electronic equipment and the corresponding random information in an associated mode, and therefore even if the screen capture image displayed by the second electronic equipment has the same screen capture image and the random information is not included in the screen capture image or cannot be seen clearly by a user, the user can quickly and accurately identify the target electronic equipment based on the random information displayed in the screen capture image and the random information displayed by the first electronic equipment.
