[0003] Most of the traditional safety identification of campus crowd flow is to obtain the number of people gathered in a certain area in real time through the camera, know the current gathering degree of crowd flow within the range of the camera, and then judge whether the current situation is safe. This kind of judgment method exists. The timeliness of security identification lags behind, resulting in low accuracy in identifying the safety of human traffic

Embodiment Construction
[0055] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0056] The identification method for the safety of traffic flow provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal device 120 communicates with the server 140 through the network. The terminal device 120 may be set at a preset location around the preset area 101 to be monitored, and collect images of the preset area 101 . The preset area 101 can be set according to actual needs. For example, the preset area 101 can be a certain area at the campus gate, and the terminal device 120 can be fixed on the...

The invention relates to a pedestrian flow safety identification method and device, computer equipment and a storage medium. The method comprises the following steps: obtaining a to-be-identified target time node; Obtaining a people flow number sequence, wherein the people flow number sequence comprises the people flow numbers of a plurality of time nodes of the monitored preset area in front of the target time node; Inputting the people flow number sequence into a people flow number prediction model to obtain a predicted people flow number corresponding to a preset area at a target time node;Obtaining the actual people flow number of the monitored preset area at the target time node; And determining safety decision information of the preset area at the target time node according to the predicted people flow number and the actual people flow number. Compared with a traditional method for judging whether the pedestrian flow is safe or not only according to the real-time pedestrian flow, the method has the advantages that whether the pedestrian flow is safe or not is comprehensively judged by combining the predicted value and the actual value of the historical pedestrian flow information on the pedestrian flow, and the accuracy and the timeliness of pedestrian flow safety recognition can be effectively improved.
Description
technical field [0001] The present application relates to the technical field of people flow identification, in particular to a method, device, computer equipment and storage medium for identifying people flow security. Background technique [0002] In areas where the flow of people is dense and may cause safety hazards, such as campuses, it is often necessary to monitor the flow of people. When the flow of people may cause safety hazards, an alarm is issued to remind relevant management personnel to prevent and evacuate the flow of people in time to ensure the safety of pedestrians. [0003] Most of the traditional safety identification of campus crowd flow is to obtain the number of people gathered in a certain area in real time through the camera, know the current gathering degree of crowd flow within the range of the camera, and then judge whether the current situation is safe. This kind of judgment method exists. The timeliness of safety identification lags behind, resu...
