Danger recognition alarm method based on video streaming data

Abstract

The invention discloses a danger recognition alarm method based on video streaming data, and the method specifically comprises the following steps: S1, collection and conversion of video data, S2, primary recognition of the video data, S3, secondary recognition of the video data, S4, intelligent learning of an recognition algorithm, and S5, data storage, and relates to the technical field of safety and protection. The invention discloses a danger recognition alarm method based on video streaming data. According to the invention, image data recognition is carried out on the DVR; secondary recognition is carried out through the cloud intelligent recognition system; the purpose of improving the recognition accuracy of the dangerous situation in the video through dual recognition is well achieved; according to the invention, networking learning training is carried out on the recognition algorithm, and the generated recognition algorithm is transmitted to the DVR for intelligent learning storage, so that the self-algorithm can be modified and increased, the application range of the recognition algorithm is greatly enlarged, and the situations of insensitive recognition and low accuracyare prevented.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a method for identifying and alarming danger based on video stream data. Background technique [0002] Video streaming refers to the transmission of video data, for example, which can be processed as a steady and continuous stream over a network. Because of streaming, a client browser or plug-in can display multimedia data before the entire file is transferred. Video streaming technology Based on the development of 2-key technology, video decoding technology and scalable video distribution technology, with the development of the Internet, the transmission of multimedia information on the Internet is becoming more and more important. Streaming technology is deeply educated for its characteristics of playing while downloading , entertainment and other industries, the video stream processing system is widely used in video surveillance places. [0003] In the process of using vide...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method of hazard identification and alarm based on video stream data, which solves the problem that the existing video identification method cannot be modified or added because the identification algorithm is entered in the DVR production process. It is relatively limited, and the recognition is often insensitive and the accuracy is low. It is impossible to realize the second recognition through the cloud intelligent recognition system after the image data recognition in the DVR, and it is impossible to improve the recognition accuracy of dangerous situations in the video through double recognition. Purpose, the problem of learning and training the recognition algorithm online and transferring the generated recognition algorithm to the DVR for intelligent learning and storage cannot be realized
