[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, an embodiment of the present invention provides a display method of a subway display terminal, the method comprising the following steps: S100, collecting subway image information, where the subway image information includes a plurality of carriage images, each of which corresponds to a carriage number; S200, performing feature analysis on the carriage image to determine the number of empty seats in each carriage number, and determining whether there is eating behavior; S300, displaying the number of empty seats and the corresponding carriage numbers on the passenger compartment display screen, and marking the guidance direction, and the displayed number of empty seats is not zero; S400, retrieve the data of the gate of the upcoming station, predict the number of people who will get on the train according to the gate of the upcoming station, and transmit the number of people who will get on the train to the display screen in the passenger compartment for display; S500 collects the sound intensity inside each compartment and displays eating behavior and sound intensity warning information on the passenger compartment display screen.

[0025] In the embodiment of the present invention, it is first necessary to install a surveillance camera in the subway car, and collect subway image information through the surveillance camera. The subway image information includes several car images, each car image corresponds to a car number, and then the car image is analyzed for features to determine the number of empty seats for each car number. When there are no empty seats in a car, the corresponding number of empty seats is zero, and it is determined whether the passenger has any eating behavior. Then, the number of empty seats and the corresponding car number will be displayed on the passenger compartment display screen, and the guidance direction will be marked to guide passengers to quickly find empty seats and improve the riding comfort. In addition, the embodiment of the present invention will also retrieve the data of the entrance gate that is about to arrive at the station, predict the number of people who are about to get on the train based on the entrance gate data, and transmit the number of people who are about to get on the train to the passenger compartment display screen for display, so as to provide passengers with more accurate riding information, which helps passengers plan their riding strategies in advance, such as moving to the inside of the car to make room. In addition, decibel meters are installed in subway cars to collect the sound intensity inside each car, and will display eating behavior and sound intensity warning information on the passenger compartment display screen, which helps remind passengers to comply with subway regulations, maintain a good riding environment, and provide passengers with a quieter and more comfortable riding environment.

[0026] like Figure 2 As shown, as a preferred embodiment of the present invention, the step of performing feature analysis on the carriage image to determine the number of empty seats for each carriage number and determining whether there is eating behavior specifically includes: S201, preprocessing the collected carriage image, the preprocessing including denoising and image enhancement; S202, retrieve the corresponding empty carriage template, determine the seat area in the carriage image according to the empty carriage template, and determine the number of empty seats according to whether each seat area is occupied; S203, identifying the hand shape and mouth shape of the passenger in the carriage image, and when the distance between the hand and the mouth is less than a preset distance value and the mouth shape meets the chewing characteristics, it is determined that there is eating behavior.

[0027] In the embodiment of the present invention, in order to accurately analyze the carriage image, it is first necessary to preprocess the collected carriage image, and the preprocessing includes denoising and image enhancement. The preprocessing method includes: mean filtering, histogram equalization and sharpening enhancement. It should be noted that each carriage collects a carriage image from a bird's-eye view, and the corresponding empty carriage template is retrieved according to the carriage number of the carriage image from a bird's-eye view. The empty carriage template is prepared in advance and is exactly the same as the shooting angle of the carriage image from a bird's-eye view. Then, the seat area in the carriage image is determined according to the empty carriage template, and the number of empty seats is determined according to whether each seat area is occupied. Finally, the hand shape and mouth shape of the passenger in the carriage image are also identified. When the distance between the hand and the mouth is less than the preset distance value, and the mouth shape meets the chewing characteristics, it is determined that there is eating behavior. Here, multiple consecutive frames of images can be analyzed, and the chewing characteristics need to be set in advance.

[0028] like Figure 3 As shown, as a preferred embodiment of the present invention, the step of determining the seat area in the carriage image according to the empty carriage template and determining the number of empty seats according to whether each seat area is occupied specifically includes: S2021, superimposing the empty carriage template with the carriage image, and determining each seat area in the carriage image according to each seat frame calibrated in the empty carriage template; S2022, determining the percentage of seat colors in each seat area in turn, and when the percentage of seat colors is higher than a preset percentage value, determining that the corresponding seat area is an empty seat; S2023, count all the empty seats to obtain the number of empty seats in each carriage number.

[0029] In an embodiment of the present invention, in order to determine the empty seats, the empty car template is superimposed with the corresponding car image, and each seat area in the car image is determined according to each seat frame pre-marked in the empty car template, and then the proportion of the seat color in each seat area is determined in turn, and the seat color is a known quantity. When the proportion of the seat color is higher than the preset proportion value, it means that the seat is basically exposed, and the corresponding seat area is determined to be an empty seat. Finally, all the empty seats are counted to obtain the number of empty seats in each car number.

[0030] like Figure 4 As shown, as a preferred embodiment of the present invention, the step of displaying the number of empty seats and the corresponding carriage numbers on the passenger compartment display screen and marking the guidance direction specifically includes: S301, displaying the numbers of the two closest carriages and the corresponding number of empty seats on a passenger compartment display screen, where each passenger compartment display screen corresponds to a carriage number; S302, guiding directions according to the carriage number on the passenger compartment display screen and the carriage number with the number of empty seats.

[0031] In the embodiment of the present invention, the two nearest car numbers and the corresponding number of empty seats will be displayed on the passenger compartment display screen. It should be understood that the number of empty seats of the displayed car number is greater than or equal to 1. If there are not two car numbers and the corresponding number of empty seats that can be displayed, then one will be displayed or not displayed. In addition, the direction will be marked according to the directional relationship between the car number on the passenger compartment display screen and the car number with the number of empty seats, so as to facilitate passengers to quickly find empty seats.

[0032] like Figure 5 As shown, as a preferred embodiment of the present invention, the steps of retrieving the data of the gate that is about to arrive at the station, predicting the number of people who are about to get on the train according to the gate data, and transmitting the number of people who are about to get on the train to the passenger compartment display screen for display, specifically include: S401, retrieve the train arrival timetable, determine the arrival time of the current train and the arrival time of the previous train, and determine the collection time period; S402, retrieve the data of the upcoming station entrance gate according to the collection time period, and obtain the number of people entering the station in the collection time period according to the station entrance gate data; S403, predicting the number of people who will get on the bus based on the number of people entering the station, determining the degree of congestion based on the number of people who will get on the bus, and sending the number of people who will get on the bus and the degree of congestion to the passenger compartment display screen for display.

[0033] In the embodiment of the present invention, the train arrival timetable is automatically retrieved to determine the arrival time of the current train and the arrival time of the previous train, and the collection time period is determined. For example, the collection time period is from one minute before the arrival time of the current train to one minute before the arrival time of the previous train. Then, the station gate data of the corresponding time period is retrieved according to the collection time period, and the number of people entering the station during the collection time period can be directly obtained according to the station gate data. Then, the number of people who are about to board is predicted based on the number of people entering the station. For example, if there is no transfer at the station, the number of people who are about to board is the number of people entering the station / 2. Finally, the degree of congestion is determined based on the number of people who are about to board. The corresponding relationship between the degree of congestion and the range of the number of people who are about to board needs to be set in advance. Then, the number of people who are about to board and the degree of congestion are sent to the passenger compartment display screen for display, reminding passengers to move to the inside of the carriage to make room.

[0034] like Figure 6 As shown, as a preferred embodiment of the present invention, the step of displaying the eating behavior and sound intensity warning information on the passenger compartment display screen specifically includes: S501, when there is eating behavior in the corresponding carriage number, displaying eating behavior warning information on the passenger compartment display screen; S502, when the sound intensity of the corresponding carriage number is higher than the preset decibel value, a sound intensity warning message is displayed on the passenger compartment display screen; S503, making the warning information flash and sending the warning information and the corresponding car number to the in-car security terminal.
