[0060] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0061] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0062] The main solution of the embodiment of the present application is: determining the label information of the current information display screen, and determining the items to be displayed according to the label information;

[0063] Acquire target scene information according to the items to be displayed, perform target positioning on the target scene information, determine candidate areas, and perform feature extraction and classification judgment based on the candidate areas to obtain target scene elements;

[0064] Identify feature information of the target scene element, reconstruct the scene based on the feature information, and obtain animation information;

[0065] The animation information is output to the information display screen for information display.

[0066] In this embodiment, for the convenience of description, the following description is made by taking the identification of the station information display device as the execution subject.

[0067] In the prior art, the information displayed at the station is usually in the form of static text or static images to provide information guidance to passengers, for example, providing guidance services inside the station to passengers in the form of static images, and informing passengers of the current purpose of a certain area in the form of text, such as ticket checking information at the ticket gate, etc., and this form of information display cannot adapt well to the environment of a railway station or a high-speed railway station with a large flow of people and a large amount of information. The current information display method cannot accurately inform passengers of the corresponding information, which, on the one hand, results in passengers being unable to obtain station information in a timely manner, and unable to process the station information well to obtain useful information. On the other hand, it also results in station staff repeatedly providing question-answering services to passengers, resulting in a decrease in the work efficiency of station staff.

[0068] The present application provides a solution, which can determine the information that currently needs to be displayed according to the position of the current station information display screen and the type of items that need to be displayed when displaying station information on a display screen in a station, and obtain the corresponding information that needs to be displayed in the station according to the information that needs to be displayed, and then animate the information that needs to be displayed so that the information can be displayed through a visual animation, and provide information guidance based on the information that currently needs to be displayed.

[0069] It can be seen from the above embodiments that the present application determines the label information of the current information display screen, determines the items to be displayed according to the label information; obtains the target scene information according to the items to be displayed, locates the target scene information, determines the candidate area, and extracts features and classifies and judges based on the candidate area to obtain the target scene element; identifies the feature information of the target scene element, reconstructs the scene based on the feature information, and obtains animation information; outputs the animation information to the information display screen for information display, can obtain the corresponding display information according to the items to be displayed, and provides visual information guidance, which can improve the efficiency of passengers in receiving station information and also improve the work efficiency of station staff.

[0070] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a station information display device, etc. The following takes the station information display device as an example to illustrate this embodiment and the following embodiments.

[0071] Based on this, the present application embodiment provides a station information display method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the station information display method of the present application.

[0072] In this embodiment, the station information display method includes steps S10 to S40:

[0073] Step S10, determining the label information of the current information display screen, and determining the items to be displayed according to the label information.

[0074] It should be noted that the information display screen is used to display station information of a certain item type in the station information. The station includes an information display matrix consisting of multiple information display screens, and each information display screen has corresponding label information to indicate the location information of the information display screen and the type of information display item. The items to be displayed refer to the types of information that need to be displayed in the daily operation of the station, including but not limited to waiting train information, ticket checking information, station internal navigation information, station passenger flow statistics information, etc.

[0075] In a specific implementation, when displaying information, the label information of the display screen of the current information display screen can be determined. The label information can use the device number of the current information display screen as the key value, and the information corresponding to the current information display screen can be determined through the station information display screen layout distribution table. For example, any information display screen can be represented in the form of <project type-device number of information display screen-array number>. For example, the label information is <Ticket Gate Information Display-YLSKM160D0LM72908451-03>, which can determine that the current information display screen is the information display screen corresponding to Ticket Gate 3 for displaying ticket gate information. When the current display screen type is determined to be ticket gate information based on the label information, the current item to be displayed can be determined. The label information of other information display screens can also be determined through the station information display screen layout distribution table shown in Table 1.

[0076] Table 1, station information display screen layout distribution table:

[0077] Project Type Device number of the information display Array Number Ticket gate information display YLSKM160D0LM72908451 01 ...... ...... ...... Station navigation display YJSAM841W1RS65843215 01 ...... ...... ...... Train dynamic display YQXVLU160DE3G02463951 01 ...... ...... ......

[0078] In a feasible implementation manner, the step of determining the label information of the current information display screen and determining the items to be displayed according to the label information includes:

[0079] Determine the grouping information of the information display screen;

[0080] Determine the label information of the current information display screen, and obtain the grouping number according to the label information and the grouping information;

[0081] The items to be displayed are determined according to the grouping number.

[0082] In a specific implementation, the grouping information of the information display screen is determined, and the label information of the current information display screen is determined, and the grouping number is obtained by combining the label information and the grouping, and then the item to be displayed is determined by the grouping number.

[0083] Step S20, obtaining target scene information according to the items to be displayed, performing target positioning on the target scene information, determining candidate areas, and performing feature extraction and classification judgment based on the candidate areas to obtain target scene elements.

[0084] It should be noted that the target scene information is the image information or model information corresponding to the item to be displayed. By cropping or filtering the image information or model information, part / all of the area in the image information or model information is obtained as the candidate area, and the target scene element refers to the scene element in the feature area that has a corresponding relationship with the target scene information and can be matched.

[0085] In a specific implementation, when determining the items to be displayed, the target scene information can be determined according to the items to be displayed. For example, when the information of the items to be displayed is the ticket gate information display type, the video surveillance screen at the ticket gate can be obtained, and the specific video surveillance screen can be determined according to the specific number of the ticket gate, and the screen to be displayed can be determined according to the items to be displayed. The scene information reflected by the current items to be displayed is determined by the items to be displayed, so the target scene information is determined according to the items to be displayed. The ticket gate display type is used as an example for explanation. Figure 2 , Figure 2 The figure is a schematic diagram of the ticket gate scene information processing. The target scene information is determined according to the label information of the current ticket gate information display screen, and the target is located according to the target scene to determine the scene features in the target scene. For example, the scene feature in the ticket gate scene is the ticket gate, so the feature area can be the ticket gate and the area in front of the ticket gate. The current area is used as a candidate area, and feature extraction is performed on the candidate area. The crowd in the ticket gate and the area in front of the ticket gate can be extracted, and the features are classified and judged to obtain the target scene elements.

[0086] In a feasible implementation manner, the steps of acquiring target scene information according to the items to be displayed, locating the target scene information, determining candidate areas, and performing feature extraction and classification judgment based on the candidate areas to obtain target scene elements include:

[0087] Acquire target scene information according to the item to be displayed;

[0088] Performing format conversion on the target scene information to obtain target scene information after format conversion;

[0089] Traversing the target scene information after the format conversion based on a sliding window to obtain identification information, and obtaining a candidate area according to the identification information;

[0090] Extracting features from the candidate area based on a feature extraction model to obtain scene features;

[0091] Classifying the scene features to obtain classification results;

[0092] When the classification result is an image-type feature, performing feature recognition on the image information to obtain an image-type target scene element;

[0093] When the classification result is a structural feature, the structural information is three-dimensionally reorganized to obtain a structural target scene element.

[0094] It should be noted that scene features refer to feature information in the candidate region that can reflect the current scene. Scene features are obtained by extracting features from the candidate scene through a convolutional neural network. Target scene elements include image-based target scene elements and structure-based target scene elements.

[0095] In the specific implementation, the corresponding target scene information is obtained according to the project to be displayed, and the target scene information is converted into a format. Before the target scene information is converted, the data type of the target scene information needs to be detected. When the target data type is an image format such as .jpeg, .png, .eps, .raw, or a video format such as .mp4, .H.264, HEVC, etc., the target scene information can be first converted into .png format or .mp4 format for processing to obtain the target scene information after format conversion, and the video file is loaded and decoded to obtain the frame sequence of the video frame or image frame, and then a separate frame is extracted from the frame sequence, and these frames are used as input frames for analysis, and the initial position, size and compensation of the sliding window are obtained, and each frame of the frame sequence is traversed based on the sliding window, so that the sliding window slides on the frame according to the set compensation, and then the visual features of the area covered by the window are extracted, including color histogram, texture features, corner detection, etc. Through deep learning analysis features, specific targets in the target scene are obtained, and candidate areas that may contain targets are determined based on recognition information. After determining the candidate region, the feature region can be confidently identified and the final candidate region can be output.

[0096] Then preprocess the input frame and normalize the input frame data through the normalization layer according to the formula: Among them, σ(x) is the variance of the input, and ε is a small constant to avoid division by zero. During the processing, it can be normalized by batch normalization. The formula is: Among them, μ B and σ B are the mean and variance of the current batch, respectively, and γ and β are learnable parameters. The normalized data frame is processed through the convolution layer, activation layer, pooling layer, and fully connected layer in sequence, and the loss difference is determined based on the loss function to output the scene features.

[0097] For the convolution layer, it can be expressed as y=f(x*ω+b), where x is the input feature map, ω is the convolution kernel, * is the convolution operation, b is the bias term, and f is the activation function, such as ReLU, Sigmoid, etc.

[0098] For the activation layer, it can be expressed as y=g(z), where g is the activation function and z is the output of the previous layer. The activation functions include ReLU: g(z)=max(0,z), Sigmoid:

[0099] The pooling layer can be expressed as y=pool(x), where pool represents a pooling operation, and the pooling operation can be maximum pooling or average pooling.

[0100] The fully connected layer can be expressed as y=f(Wx+b), where W is the weight matrix, x is the input vector, b is the bias term, and f is the activation function.

[0101] For the loss function, we can use the mean square error (MSE): Or via cross entropy loss: y o,c is the one-hot encoding of the true label, p c is the probability that the model predicts class c.

[0102] When classifying scene features, feature extraction can be performed through F=CNN(I), where I is the input image, including pictures and videos, and F is the extracted feature. The feature is then input into a classifier, such as a support vector machine (SVM), and based on the output of the classifier, it is determined whether the feature belongs to an image class or a structure class. When the classification result is an image class feature, feature recognition is performed on the image information to obtain an image class target scene element. When the classification result is a structure class feature, the structure information is reorganized in three dimensions to obtain a structure class target scene element.

[0103] Step S30, identifying feature information of the target scene element, and reconstructing the scene based on the feature information to obtain animation information.

[0104] It should be noted that feature information includes geometric features, texture features, semantic features, etc. Scene reconstruction is the process of reconstructing the three-dimensional structure of the scene based on the extracted feature information.

[0105] In the specific implementation, after obtaining the characteristic information of the target scene element, the characteristic information of the target scene element can be reconstructed. Taking the ticket gate as an example, refer to Figure 2 , Figure 2 This is a schematic diagram of information processing at the ticket gate scene. By acquiring the image of the ticket gate area, the queue in front of the ticket gate is detected based on the ticket gate gate to determine the queue status of the current gate gate queue. At the same time, the features of the people in the current queue can be recognized to determine whether the people in the current queue are carrying large luggage. Figure 2 In the process, the current queue length can be determined by markings, and the number of people or the density of people in the current queue can be determined by head detection. Therefore, the crowding degree of the current queue can be reflected by the number of people or the density of people. At the same time, the same operation is performed on the queue information in front of each gate to determine the crowding degree of the current queue. The crowding weight of each person can be set to 1, and the crowding weight of each large luggage can be set to 0.4. The specific weight setting can be set according to the actual situation. Therefore, the crowding degree of the queue can be determined according to the crowding degree value of the current queue, and then the scene can be reconstructed through the feature information to obtain the following Figure 3 Animated schematic diagram of the crowdedness of the ticket gate shown. The information display screen is used to display the current train information and icons reflecting the crowdedness of the current queue. The area to be displayed can correspond one-to-one with the number of gates at the ticket gate. Similarly, when navigating within the station, the positioning information can be determined according to the current location of the information display screen. Passengers can wake up the three-dimensional model of the station on the information display screen, and when displaying, the current positioning information is used as the center of the display, and the current location is highlighted. The three-dimensional model can rotate according to the sliding action of the passenger. The passenger can choose any point in the model as the destination, and the current positioning information and the location of the destination are combined to generate a path, and an animated display of the path is generated, with the starting point being the direction the current passenger is facing. At the same time, the train operation information can also be obtained, and the operation status of the current train can be displayed on the corresponding information display screen in the waiting room, including the distance from the current station, the running speed and other information, such as Figure 4 As shown, Figure 4 It is a schematic diagram of the train's running animation. It can be used to describe the animation effect of the train entering the station, and enable passengers to obtain the train's running status in real time. It can reflect the vehicle's running speed, the train's delay information, and display the train's running status.

[0106] In a feasible implementation manner, the step of identifying the feature information of the target scene element, reconstructing the scene based on the feature information, and obtaining the animation information includes:

[0107] Identify the target scene element to obtain a target scene element identification result;

[0108] When the target scene element recognition result is an image-type target scene element, performing image grayscale processing on the image-type target scene element to obtain a grayscale image;

[0109] Performing feature recognition on the grayscale image to determine character features and scene features;

[0110] The character features and the scene features are reconstructed to obtain animation information.

[0111] In a specific implementation, the target element is identified to obtain the recognition result of the target scene element. When the target scene element is an image-type target scene element, the image grayscale processing can be performed on the image-type target scene element. According to the formula: gary =0.2989I R +0.5870I G +0.1140I B The image is grayed to obtain a gray image, and feature recognition is performed on the gray image to determine character features and scene features, and scene reconstruction is performed on the character features and the scene features to obtain animation information.

[0112] In a feasible implementation manner, the step of performing feature recognition on the grayscale image to determine character features and scene features includes:

[0113] Performing image segmentation on the grayscale image to obtain a segmented image;

[0114] Performing image recognition on the segmented image to obtain a regional feature image and a person feature image;

[0115] Identifying the regional feature image to obtain the number of regional features;

[0116] Dividing the character feature image according to the number of regional features to obtain character queue information;

[0117] Character features are obtained according to the character queue information, and scene features are obtained according to the regional feature image.

[0118] In the specific implementation, first, a segmentation algorithm, such as threshold segmentation, edge detection or region growing, is applied to the grayscale image to distinguish different regions in the image, so that the person and the background can be identified and separated; the segmented image is further analyzed to identify the regional feature image and the person feature image; the regional feature image is analyzed to count the number of features, for example, the number of edges in the image or the area of ​​a specific texture area is calculated. According to the number of identified regional features, the person feature image is divided, and the relative position or distribution of the person in the image can be determined according to the number of background features; by analyzing the divided person feature image, the person queue information is constructed, which may include the arrangement of the person, the formation or the number of individuals in the group; finally, the person features, such as height, body shape or any distinguishable features, are extracted from the person queue information. At the same time, scene features, such as the layout of the scene, the distribution of objects, etc., are extracted from the regional feature image.

[0119] In a feasible implementation manner, after the step of identifying the target scene element to obtain the target scene element identification result, the step further includes:

[0120] When the target scene element recognition result is a structural target scene element, determining a real scene parameter according to the structural target scene;

[0121] Determining real scene features according to the real scene parameters, and performing feature annotation according to the types of the real scene features;

[0122] A three-dimensional animation model is obtained based on the real scene parameters and the feature annotations, and the three-dimensional animation model is reconstructed to obtain animation information.

[0123] In the specific implementation, the recognition result of the target scene element is obtained by identifying the target element. When the target scene element is a structural target scene element, the structural target scene element is identified from the input data through the deep learning model, and the real scene parameters are determined according to the target scene. According to the identified structural elements, the size, proportion and layout space of the scene are estimated, and the geometric shape, texture, color and other characteristics of the scene elements are analyzed to provide necessary information for 3D modeling. According to the type of real scene features, such as room area features, classification and labeling are carried out, such as water room, toilet, waiting room, convenience store, ticket gate and other scenes, to prepare for automated modeling, using the identified and labeled data According to the method, a 3D animation model of a scene is constructed using 3D modeling software or an algorithm, and the generated 3D model is refined, including adding textures, materials and other details to improve the realism of the model. The 3D animation model is adjusted and reconstructed according to the real scene parameters to ensure that the scale and layout of the model are consistent with the actual scene. Animation keyframes are added to the 3D model, and the motion path, speed and time series of the model are defined. The real scene parameters are subjected to denoising to obtain denoised scene parameters; multiple model geometric features are generated based on the denoised scene parameters; the model geometric features are rendered based on the feature annotations to obtain rendered geometric features; the rendered geometric features are reconstructed to obtain animation information. The rendered animation is subjected to post-processing such as color correction and special effects addition to improve the animation quality, and the animation sequence is output as a video or other suitable format for display or further editing.

[0124] Step S40: output the animation information to the information display screen for information display.

[0125] In the specific implementation, after obtaining the animation information, the current animation information can be displayed on the corresponding information display screen. If the animation information to be displayed exceeds the resolution of a single information display screen, multiple information display screens can be combined and displayed to output the animation information on the information display screen for displaying the train information in the station and the navigation information inside the station.
