Problems solved by technology

[0005] The purpose of the present invention is to overcome the existing upgrading of network cameras to network smart cameras. The information of face recognition does not conform to the H264 encoding standard, which is inconvenient to upgrade. The simple replacement of using network smart cameras is expensive and inconvenient for network smart cameras. promotional use of

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] Such as figure 1 As shown, a method for adding face recognition information into an H264 video stream is characterized in that: comprising the following steps,

[0031] In step (1), the face recognition information is encapsulated into data, and the encapsulated face recognition information conforms to the encoding standard of the H264 video stream,

[0032] (1) The data header of face recognition information is increased with the first flag of fixed hexadecimal data;

[0033] (2) Calculate the data length of the face recognition information, and add the data length bit to the rear part of the flag;

[0034] (3) face recognition information is added to the rear part of the data length ...

Abstract

The invention discloses a method of adding face recognition information into H264 video stream, after data packaging and anti-competition processing are carried out on the face recognition information, the H264 video stream is added and is transmitted to a client to extract the face recognition information in the H264 code stream data, the face recognition information is added without influencing the H264 standard code stream so as to facilitate development of a network intelligence camera based on the existing network camera products, on the one hand, the product performance is improved; on the other hand, the pace to put a product on the market is accelerated, and the method has good application prospect.

Description

technical field [0001] The invention relates to a method for adding face recognition information into an H264 video stream, and belongs to the technical field of video monitoring. Background technique [0002] At present, in order to achieve higher encoding efficiency and reduce the data volume of video streams, the video encoding method of network cameras basically adopts H264 encoding. According to market demand, the application of network smart cameras with face recognition function will become more and more extensive. [0003] In terms of video processing, the network camera is mainly divided into two modules: the image acquisition and encoding module and the data processing and transmission module. The processing and transmission module is mainly responsible for packaging the H264 code stream data in RTP and other ways, and then sending it to the client through the Ethernet network, and the client decodes and displays the code stream data. It can be seen that compared ...
