The invention provides a monitoring and early warning method for people stream analysis, and the method comprises the steps that a time-of-flight TOF camera carries out the environment photographing of a monitoring region according to an image collection instruction, obtains three-dimensional point cloud data, and transmits the three-dimensional point cloud data and a camera ID to a monitoring processor; the monitoring processor performs filtering processing on the three-dimensional point cloud data to obtain filtered three-dimensional point cloud data, performs facial feature detection processing on the filtered three-dimensional point cloud data to obtain facial three-dimensional point cloud data, and stores the facial three-dimensional point cloud data in a facial three-dimensional point cloud data list; the monitoring processor performs expression recognition processing based on the facial three-dimensional point cloud data, obtains an expression type of the facial three-dimensional point cloud data, performs matching detection on the facial three-dimensional point cloud data and image data in a to-be-identified personnel information database when it is determined that the expression type is a preset expression type to obtain detection result data, generates an alarm message according to personnel information when it is judged that a detection state is a preset state,, andsends the alarm message to an early warning terminal.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a monitoring and early warning method for analyzing people flow. Background technique [0002] With the rapid development of information technology in recent years, people have applied advanced information technology, communication technology and computer processing technology to various fields, which not only brings convenience to people's life, but also provides guarantee for people's living environment safety. [0003] With the development of camera technology and image processing technology, more and more places use cameras to monitor people's living environment and save the monitored data to improve the safety of the living environment. For example, cameras are installed in shopping malls, banks and other living places where people often move, to obtain real-time images of the environment for video recording and storage, or to output through monitoring and display devices, so ...
