Problems solved by technology

However, based on the theoretical transmission speed of HID, it is difficult to transmit large data such as pictures. Even if the pictures are compressed, it is difficult to achieve a high transmission frame rate, which directly affects the synchronous preview effect at the other end.

Embodiment 1

[0046] Please refer to Figure 1 to Figure 3 , the present embodiment provides a two-way preview method based on the camera of the equipment outside the HID cabinet, which may include the following steps:

[0047] S10. The camera is directly connected to the device outside the cabinet, and the first video stream acquired by the camera is displayed on the screen of the device outside the cabinet;

[0048] In order to give priority to the preview effect of the equipment outside the cabinet, the camera is directly connected to the equipment outside the cabinet.

[0049] S20. Obtain the screen data and then transcode to obtain the second video stream;

[0050] By obtaining screen data and then transcoding to obtain video data, the acquisition rate is greatly improved, and the streaming media solution is used for storage. Compared with the data volume of picture frames, the encoding method of video stream is greatly reduced, which can reduce the size of transmitted data, thereby i...

Embodiment 2

[0074] In this embodiment, a device is provided, such as Figure 4 shown, including:

[0075] The first video stream display module, the second video stream acquisition module, the second video stream transmission module and the second video stream playback module;

[0076] The first video stream display module is used to directly connect the camera to the equipment outside the cabinet, and display the first video stream acquired by the camera on the screen of the equipment outside the cabinet;

[0077] The second video stream acquisition module is used to acquire screen data and then transcode to obtain the second video stream;

[0078] The second video stream transmission module is configured to send the second video stream to the terminal in the cabinet according to the HID protocol;

[0079] The second video stream playing module is used for the terminal in the cabinet to play the second video stream.

[0080] In a possible implementation manner, the second video stream...

Embodiment 3

[0089] This embodiment provides a computer-readable storage medium, such as Figure 5 As shown, a computer program is stored thereon, and when the computer program is executed by a processor, any implementation manner in the first embodiment can be realized.

[0090] The technical solution provided in the embodiment of the present application has at least the following technical effects or advantages: a bidirectional preview method, device and medium based on the camera of the equipment outside the HID cabinet provided in the embodiment of the present application, without using additional fast protocols such as ADB and MTD For data transmission, continue to use the original HID transmission mode to ensure that the communication method remains unchanged, and no additional driver installation is required; data transmission is performed in the form of video streaming instead of frame data acquisition in the form of screenshots, which greatly improves the acquisition rate, and vide...

Abstract

The invention discloses a two-way preview method, device and medium of a camera of an HID out-of-cabinet equipment, and relates to the technical field of financial services. The method includes: step 10, the camera is directly connected to the out-of-cabinet equipment, and displayed on the screen of the out-of-cabinet equipment The first video stream obtained by the camera; Step 20, acquire screen data and then transcode to obtain a second video stream; Step 30, send the second video stream to the terminal in the cabinet according to the HID protocol; Step 40, in the cabinet The terminal plays the second video stream. The invention provides a bidirectional preview method, device and medium based on the camera of the HID equipment outside the cabinet, which optimizes the bidirectional preview effect of the camera video on the equipment outside the cabinet and the terminal in the cabinet without additionally installing a driver.

Description

technical field [0001] The invention relates to the technical field of financial services, in particular to a two-way preview method, device and medium based on a camera of equipment outside an HID cabinet. Background technique [0002] At present, all major banks have added binocular camera modules to the counter equipment such as new counters, and introduced artificial intelligence functions such as face recognition and face comparison. The core requirement of this need is to import the camera data on the equipment outside the cabinet to the terminal inside the cabinet for data processing; at the same time, the equipment outside the cabinet also needs to be able to perform synchronous preview to guide customers outside the cabinet to take pictures. However, the configuration of devices outside the cabinet currently on the market can only meet one way of video data transmission, that is, the camera is directly connected to the terminal in the cabinet or the camera is direct...
