The alarm information identification method provided by the present application is applied to a server, and the method includes: when receiving the alarm information based on the motion detection event sent by the front-end device, obtaining multiple alarm pictures targeted by the alarm information; the alarm picture is The pictures collected by the front-end equipment within the preset time from the triggering time of the motion detection event; use a variety of human figure recognition algorithms to perform human figure recognition on each alarm picture; recognize the human figure contained in each alarm picture according to each human figure recognition algorithm Quantity, calculating the degree of discreteness corresponding to each human figure recognition algorithm; according to the number of human figures contained in each alarm picture identified by the first human figure recognition algorithm with the smallest degree of dispersion, determine whether there is an intruder; if so, determine that the alarm information is valid alarm information. The alarm information identification method, server and system provided in this application can identify the alarm information reported by the front-end equipment, and reduce the possibility of invalid operations by the server.
Description
technical field [0001] The present application relates to the field of video surveillance, and in particular, to a method, server and system for identifying alarm information. Background technique [0002] The video surveillance system is an important part of the security protection system, and it is a comprehensive system with strong prevention ability. At present, with the rapid development of social economy and the advancement of science and technology, video surveillance systems are widely used in many occasions due to their intuitive, accurate, timely and content-rich features. However, the large-scale application of video surveillance makes it difficult to identify by human beings. [0003] In the existing video surveillance alarm system, the front-end equipment usually performs motion detection in the area to be monitored, and then triggers a motion detection event when a moving object is detected, and reports alarm information to the server when a motion detection e...
