Detailed Description
So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 2, an embodiment of the present application discloses a display screen-based passenger flow guidance method, which is suitable for passenger flow management of a platform of a subway station, and includes:
s100, obtaining an image of the interior of a carriage of a train to be entered, and determining the number of passengers in each carriage through image analysis;
fig. 1 shows a suitable scenario of the passenger flow guiding method of the embodiment, in a subway station, a train runs on a track in an orbital area, passengers are on a platform, and the passengers can get on or off the train through a screen door. A plurality of waiting areas can be arranged on the platform and respectively correspond to different shielding doors and carriage access doors. On the platform, an image pickup unit 20 and a display screen 30 are provided, and the image pickup unit 20 can pick up an image of a waiting area. The same imaging means is provided in the train car to capture images of the interior of the car. The camera unit on the train, the camera unit 20 on the platform and the display screen 30 are in communication connection with the background control system 10 in a wireless or wired manner.
The passenger flow guidance method of the present embodiment may be implemented by the back-office control system 10, or may be implemented by the back-office control system 10 and other units together. Next, the operation of the passenger flow guidance method according to the present embodiment will be described by taking the background control system 10 as an example.
In step S100, the train waiting for entering may control the camera unit in the train car to capture the image of the interior of the train car, and then transmit the image of the interior of the train car to the back office control system 10. The background control system 10 obtains the images of the interior of the train to be entered, and obtains the number of passengers in each train through image analysis, such as face recognition.
S200, determining the estimated getting-off number of each compartment according to the getting-off prediction model and the number of passengers in each compartment;
for example, the getting-off prediction model may be obtained by multiplying the statistical getting-off proportion by the number of passengers in each compartment, so as to obtain an estimated number of people getting-off in each compartment. According to historical data, the getting-off proportion in the subway station in each time period can be counted, namely the ratio of the number of the passengers getting off to the total number of the passengers on the train at that time. This is because, from the overall data point of view, the traffic of people is approximately close in the same time period every day in one subway station. Therefore, the getting-off proportion in each time period can be counted from the historical data so as to reasonably estimate the number of people getting off.
In this case, step S200 may specifically be: acquiring current time, and matching get-off proportion corresponding to the current time from the get-off prediction model; and determining the estimated getting-off number of each carriage according to the getting-off proportion and the number of passengers in each carriage.
It is understood that during the statistics, workdays and holidays can also be distinguished. Therefore, the estimated number of people getting off can be consistent with the fluctuation situation between working days and holidays.
For example, the getting-off prediction model may be based on analysis of the movement trajectory of the person on the image of the interior of the compartment. Generally, in a car, a passenger who arrives at a station and needs to get off the car moves to the vicinity of a car door in advance. Therefore, the estimated passengers getting off can be identified by analyzing the personnel moving track of the images in the carriage, so that the estimated number of people getting off in each carriage is obtained in a gathering manner.
It is understood that, considering that passengers may stay near the car door all the time, the passengers who are near the car door but do not move may be directly counted in the number of alighting persons when the estimated number of alighting persons is counted.
S300, acquiring images of waiting areas on the incoming platforms according to preset time arrangement, and determining the number of waiting people in each waiting area through image analysis;
s400, determining the estimated pedestrian volume of getting on or off the bus in each waiting area according to the estimated number of people getting off the bus in each carriage and the number of waiting people in each waiting area;
the image capturing unit 20 on the platform can capture images of the waiting area on the platform at a preset time schedule, such as a timed or untimed time. The background control system 10 receives the images of the waiting areas on the inbound platform, and obtains the number of waiting people in each waiting area through image analysis, such as face recognition. The estimated pedestrian flow for getting on or off the bus in each waiting area, namely the number of people getting on or off the bus, can be determined by combining the estimated number of people getting off the bus in each carriage.
S500, identifying a waiting area with dense passenger flow and a waiting area with sparse passenger flow according to the estimated passenger flow for getting on and off the train in each waiting area, and determining a passenger flow guide signal picture;
according to the estimated passenger flow of getting on or off the bus in each waiting area, the waiting area with dense passenger flow and the waiting area with sparse passenger flow can be determined, and then a passenger flow guide signal picture is determined for guiding passengers on the platform to move to the waiting area with sparse passenger flow.
In some embodiments, the area of each waiting area may be different, and when a waiting area with dense traffic flow and a waiting area with sparse traffic flow are determined, the ratio between the traffic flow and the waiting area may also be determined according to the traffic flow density, that is, the ratio between the traffic flow and the waiting area is estimated. In this case, step S500 may specifically be:
acquiring the area of each waiting area, and determining the estimated traffic density of getting on and off the bus in each waiting area by combining the estimated traffic of getting on and off the bus in each waiting area;
comparing the estimated traffic density of getting on and off the train in each waiting area with a preset traffic density threshold value, and identifying waiting areas with dense traffic and waiting areas with sparse traffic;
and determining a passenger flow guide signal picture according to the passenger flow dense waiting area and the passenger flow sparse waiting area.
And S600, controlling a display screen of the waiting area and displaying a people flow guide signal picture.
And controlling a display screen corresponding to the waiting area according to the passenger flow guide signal picture, displaying the corresponding passenger flow guide signal picture, and guiding passengers on the platform to move to the waiting area with sparse passenger flow.
