Description

Technical Field

[0001] The present invention belongs to the technical field of data visualization, and particularly relates to a method and system for immersive interaction of spatio-temporal data based on video structuring technology. Background Art

[0002] With the development of data analysis and visualization technologies, various visualization display and interaction methods are now commonly applied in fields such as data analysis, data statistics, and data mining. For the data obtained through structuring in videos, which has characteristics such as being massive, spatio-temporal, and having a tight correlation between objects, it is a type of spatio-temporal data. The use of front-end visualization and interaction technologies can help users efficiently view and analyze such data. Currently, visualization and interaction methods for spatio-temporal data include web visualization technologies such as Chart chart technology and map GIS visualization technology, as well as interaction methods that combine multi-field technologies such as virtual reality technology and multi-dimensional models.

[0003] A relatively typical video structured object visualization interaction method is to visually display spatio-temporal data through a list. This method can express the continuity and complete attributes of object data, but spatial information cannot be intuitively expressed. Especially when the data is paged, the thinking of browsing and analyzing data is more likely to be interrupted.

[0004] The spatio-temporal data interaction technology based on map GIS can better express geographical spatial information. The spatio-temporal data visualization method based on multi-dimensional models has powerful computing capabilities and is used for statistical analysis of a large number of point data. Both of these methods are applicable to the large-scale overview of video structuring and the display of data volume distribution, and are not applicable to video structured object subscriptions with clear spatial destinations and web application systems with lightweight requirements.

[0005] Charts such as relationship diagrams, line charts, and pie charts are suitable for visualizing a certain type of data attribute or data statistical results, and cannot express the complete attributes of spatio-temporal data. Moreover, they focus on visual effects and lack spatial interaction.

[0006] In view of this, it is very meaningful to propose a method and system for immersive interaction of spatio-temporal data based on video structuring technology. Summary of the Invention

[0062] Figure 2 The embodiments of the present invention disclose a method for immersive interaction of spatio-temporal data based on video structuring technology, as Figure 2 and Figure 3 shown, the method includes the following steps:

[0063] S1. Select a historical time point and a spatial location of interest;

[0064] S2. Initiate a request to obtain video-structured spatio-temporal data sources for the time periods before and after the time point;

[0065] S3. Determine whether the data of the video-structured spatio-temporal data source returned by the request is empty. If so, execute S4; otherwise, execute S5;

[0066] S4. Determine whether the total number of requests is greater than N. If so, expand the time range of the request and execute S2; otherwise, end.

[0067] Specifically, in this embodiment, S4 further includes ending and prompting the user that there is no structured spatio-temporal data within this time period, where N is the maximum number of allowed repeated requests. Preferably, in this embodiment, the value of N is set to 30.

[0068] S5. Obtain the time difference between spatio-temporal data to calculate the step size of the data object, and establish a data model with time anchor point attributes.

[0069] Specifically, in S5, the step size of the data object is calculated through a piecewise function and the Pearl model using the time difference between spatio-temporal data, which is used as a factor for transition during object rendering.

[0070] The calculation formula is as follows:

[0071]

[0072] Where t is the absolute value of the time difference between two adjacent spatio-temporal data, in seconds, s is the step size, and a, b, c, and K are the parameters of the Pearl model. Preferably, in this embodiment, the value of a is 0.25; the value of b is 1; the value of c is 5; and the value of K is 3.

[0073] By using a piecewise function and the Pearl growth model to calculate the interactive transition factor between data, smooth transition between rendering objects in high-dimensional spatio-temporal space is achieved, and its visual perception conforms to the principle of objects being larger when closer and smaller when farther away, as well as the rhythm of time, which conforms to the habits and laws of humans perceiving time and space. This kind of transition enables users to be immersive and quickly immersed.

[0074] Specifically, as Figure 4 shown, the data model diagram includes point ID, point name, structured ID, photo, coordinates, time, time anchor point, longitude and latitude, and background photo, etc.

[0075] S6. Further define the background of the page.

[0076] Specifically, in this embodiment, the defined resolution is the resolution of the video, and the page background is a Gaussian-blurred real background photo.

[0077] S7. Render the structured data at the current time point in proportion to the spatial position, and bind rendering components with interactive functions as needed to interactively display the specific attributes of this piece of data.

[0078] Specifically, the rendering component includes hover and click interaction events. The hover event is to display the real-time background image at the current time point, and the click event is to request and display the structured attributes of the current object from the backend.

[0079] S8. Calculate the transparency opacity and scaling ratio transform of the current rendering object according to the obtained step size;

[0080] S9. Add a global listener for the mouse wheel scrolling event DOMMousescroll and set the initial anchor value to 0;

[0081] S10. Listen for whether the scroll wheel is scrolled. If so, execute S11; otherwise, end.

[0082] S11. When the scroll wheel scrolls down, subtract 1 from the current anchor value. When the scroll wheel scrolls up, add 1 to the current anchor value, and execute S7;

[0083] S12. Determine whether the value obtained by subtracting the current anchor value from the anchor value of the last spatio-temporal data is less than M. If so, execute S2; otherwise, end. Here, M is the range of data requested again specified by the user.

[0084] The present invention clearly displays the spatial positions and time sequences of structured objects by using web technology, combines piecewise functions and the Pearl growth model to calculate the interaction transition factors between data, enables smooth transitions between rendering objects in high-dimensional space-time, allows users to quickly immerse themselves in the actual scene for interaction, and can quickly locate the spatial points and time points of interest to users. By quickly browsing in a short time, key structured objects can be captured, invalid time periods can be skipped, time costs can be saved, and associated structured objects under the same spatio-temporal conditions can be quickly locked, improving the user experience.

[0085] Furthermore, the present invention can conveniently fuse and display the time attributes and spatial attributes of data, to a certain extent solve the spatial chaos phenomenon in the display of a large amount of structured objects, with good visual effects; can quickly and conveniently overview the video structured objects within a historical time period, quickly discover the time, location, and associated objects of interest (such as fires, dangers, etc.); can conveniently superimpose all attributes of the rendered data on the structured objects, improving the user experience; the present invention can configure and change calculation parameters in real time to meet the personalized needs of users, such as speed requirements; interactive optimization has been done for video structured spatio-temporal data, but the data type is not limited, and any data with spatio-temporal attributes can be used as the input of this method, with strong scalability.
