Embodiment 1

[0058] Specifically, such as figure 2 As shown, the communication process between the multi-optical handheld device and the mobile terminal includes;

[0059] Step 1. Start the WIFI module of the wireless communication module and create a SoftAP hotspot;

[0060] SoftAP hotspot is a technology that provides a wireless access point through a WIFI module, and a mobile terminal can connect to a multi-optical handheld device through a SoftAP hotspot. SoftAP hotspots can be password protected to prevent unauthorized mobile terminals from connecting to multi-optical handhelds.

[0061] After the multi-light handheld device is powered on, it can automatically start the UDP connection to wait for the client to connect to the multi-light handheld device. A UDP connection refers to a User Datagram Protocol (User Datagram Protocol) connection.

[0062] Step 2, when the client is connected to the SoftAP hotspot, the wireless communication module monitors the communication status of al...

Embodiment 2

[0088] Corresponding to the above-mentioned embodiments, the present application provides a video transmission method applied to an image acquisition device, such as Figure 4 As shown, the method includes:

[0089] 410. Receive a video request sent by the client, where the video request includes a target video type;

[0090] Preferably, the video request sent by the receiving client includes:

[0091] 411. Generate a SoftAP hotspot;

[0092] 412. When the client is connected to the SoftAP hotspot, determine a target channel according to the communication states of all channels of the client;

[0093] 413. Establish a communication link with the client through the target channel.

[0094] 420. Control the lens corresponding to the target video type to collect a real-time video stream;

[0095] 430. Generate a message frame according to the preset number of frames of the message frame and the real-time video stream, the preset number of frames is determined according to the...

Embodiment 3

[0107] This application provides a video transmission method, which is applied to a client, and the method includes:

[0108] 610. Send a video request to the image acquisition device, where the video request includes the target video type;

[0109] 620. Receive the message frame returned by the image acquisition device, the message frame is generated by the image acquisition device according to the preset frame number of the message frame and the real-time video stream, and the preset frame number is based on the preset The set buffer duration is determined, and the message frame includes a key frame and a corresponding coded frame;

[0110] 630. Determine the decoding order of each message frame according to the start word included in the message frame;

[0111] 640. Decode key frames included in the message frame and corresponding coded frames according to the decoding sequence, generate real-time video, and display it visually.

[0112]Preferably, the decoding of the key...

Abstract

The invention provides a video transmission method and device applied to image acquisition equipment, and the method comprises the steps: receiving a video request sent by a client, wherein the video request comprises a target video type; controlling a lens corresponding to the target video type to acquire a real-time video stream; generating a message frame according to a preset frame number of the message frame and the real-time video stream, the preset frame number being determined according to a preset buffer duration, the message frame comprising a key frame and a corresponding coded frame; and sending the message frame to a client, so that the client analyzes the message frame and visually displays an analysis result, and the stability of video transmission under the condition of signal fluctuation or network instability can be further ensured by setting the frame number of the message frame to be the preset frame number determined according to the buffer duration. And the problem that in an existing multi-light handheld device, observation is realized through an eyepiece and it is inconvenient to observe is solved, and multi-user and multi-video type simultaneous observation is supported.

Description

technical field [0001] The invention relates to the field of image transmission, in particular to a video transmission method and device applied to image acquisition equipment. Background technique [0002] With the continuous development of infrared imaging, low-light imaging and other technologies, the single visible light lens of traditional handheld observation devices such as night vision devices can no longer meet the observation needs of multiple scenes. The new multi-light handheld device adds infrared and low-light technology on the basis of visible light, which can collect light signal data in different frequency bands, meeting the observation needs in various situations such as night and low illumination. [0003] However, the existing multi-light handheld devices only have one eyepiece for observation, do not have communication functions, and can only be observed by one person through the eyepiece. Simultaneous observation of infrared, low-light and visible ligh...
