Automatic danger early warning system and method for law enforcement recorder

Abstract

The invention, which relates to the technical field of law enforcement recorders, provides an automatic danger early warning system of a law enforcement recorder. A dangerous environment early warningsystem is established by utilizing a scene recognition module, a temperature detection module, an air monitoring module and a central processing unit with strong operational capability. The inventiondiscloses an automatic danger early warning method adopting a law enforcement recorder. A static picture and a dynamic video of a current scene are identified by adopting edge calculation and face recognition technologies; scene features, article features in a scene, and facial features and action features of a person in a scene picture or a video are obtained, and whether the current environmentis a dangerous environment or not is determined in combination with a voice recognition text, a human body temperature value and a dangerous gas concentration; alarm information is quickly fed back to a command platform through a 4G or 5G network for command scheduling and emergency processing, so that the personal danger of field law enforcement officers or workers is effectively reduced.
