Description

Technical Field

[0001] This application belongs to the field of big data visualization technology, and in particular relates to an adaptive display method and apparatus for image data. Background Technology

[0002] Currently, massive amounts of data are generated every moment, and how to collect, refine, and utilize this data is a challenge. Traditional data visualization represents each data point in the database as a single image element, while also representing the various attribute values ​​of the data in a multidimensional form, allowing for observation of the data from different dimensions and thus enabling deeper observation and analysis.

[0003] Data visualization primarily uses graphical means to clearly and effectively convey and communicate information; it's simply a different way of presenting data. However, big data visualization involves massive amounts of data, diverse types, and low value density, requiring storage, aggregation, and preprocessing. Traditional data visualization methods cannot be accurately applied to big data processing. For example, when using a fisheye lens to view data details during big data visualization, the following problems often occur: the data is too densely packed in the display area, making it difficult to see clearly; or, the large amount of data loaded during visualization affects the viewing function.

[0025] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] like Figure 1 The diagram shown is a flowchart illustrating a method for displaying image data according to an embodiment of this application. A method for displaying image data includes:

[0027] S101, based on the trigger of the target location within the display area, obtain the density of scattered data in the area corresponding to the target location;

[0028] S102, at least based on the density of the scattered data, determine the scattered data that the display area corresponding to the target location can display; wherein, the display area is a part of the display area;

[0029] S103, by adjusting the relative size of the background image on the display area and the display area, enlarges and displays the scatter data that can be displayed in the form of an image within the display area.

[0030] In S101, the user triggers the display of a target location. Based on the user's trigger, the system obtains the density of the scattered data in the area corresponding to the target location. The area corresponding to the target location is used to indicate the surrounding area, including the target location.

[0031] In S102, the visualization of image data can be achieved by adaptively adjusting the base map; alternatively, the visualization of image data can be achieved by adaptively adjusting the display radius.

[0032] In the adaptive adjustment of the base map: determine the scattered data that can be displayed in the display area corresponding to the target location, including: first determine the number of data to be displayed in the display area, and then determine the scattered data that can be displayed in the display area based on the number of data to be displayed in the display area and the density of the scattered data;

[0033] In the adaptive adjustment of the display radius scheme: determining the scattered data that the display area corresponding to the target position can display includes: determining the display radius based on the display distortion of the magnifying glass, the specified image display size corresponding to the scattered data, and the density of the scattered data; determining the display area based on the target position and the display radius, so as to determine the scattered data that the display area can display.

[0034] Here, the display area is used to indicate the area centered on the target location and displaying scattered data at that target location.

[0035] In S103, in the adaptive adjustment of the base map scheme: the display area size remains unchanged, and the scattered data that can be displayed in the display area is magnified in the form of an image by adjusting the size of the base map on the display area.

[0036] In the adaptive adjustment of the display radius scheme: the size of the base map on the display area remains unchanged, and the scattered data that can be displayed is enlarged in the form of an image within the display area by adjusting the size of the display area.

[0037] This application embodiment is based on triggering a target location within the display area to obtain the density of scattered data in the area corresponding to the target location; then, it determines the amount of scattered data that can be displayed in the display area corresponding to the target location based at least on the density of the scattered data; finally, by adjusting the relative size of the base map and the display area, it enlarges and displays the displayed scattered data in the form of an image within the display area. Therefore, it is possible to achieve a visual display of large amounts of data at the target location, improving the visualization effect and solving the problem of resource waste caused by the inability to view image data due to the large amount of data loaded.

[0038] A method that adaptively adjusts the base map is used to visualize image data.

[0039] like Figure 2 The diagram shown is a flowchart illustrating a method for displaying image data based on an adaptive adjustment of the base map, according to another embodiment of this application.

[0040] The embodiments of this application are as follows: Figure 1 This method, based on an optimized implementation of the previous example, is a further optimization of the image data display method using an adaptive base map adjustment scheme. It includes at least the following steps:

[0041] S201, based on the trigger of the target location within the display area, obtain the density of scattered data in the area corresponding to the target location;

[0042] S202, at least based on the density of the scattered data, determine the scattered data that the display area corresponding to the target location can display; wherein, the display area is a part of the display area;

[0043] S203, Adjust the scaling factor of the background image on the display area to enlarge and display the scatter data that can be displayed in the display area as an image.

[0044] Among them, steps S201 and S202 are respectively with Figure 1 The processes of steps S101 and S102 are similar and will not be repeated here.

[0045] In step S203, while keeping the size of the display area unchanged, the scaling factor of the base map is adaptively adjusted so that the scattered data within the display area are displayed at their respective new positions with their respective magnification factors; the scattered data outside the display area are displayed at their new positions in the form of scattered points.

[0046] It should be noted that if the scattered data in the area corresponding to the target location is very dense, the system can adaptively distribute the dense scattered data according to the number of data points to be displayed in the display area, thus obtaining the scattered data that can be displayed in the display area. If the scattered data in the area corresponding to the target location is very sparse, the system will adaptively cluster the sparse scattered data according to the number of data points to be displayed in the display area, thus obtaining the scattered data that can be displayed in the display area.

[0047] In a preferred embodiment, for step S202, the scattered data that can be displayed in the display area corresponding to the target location can be determined based on the display radius and the density of the scattered data; specifically as follows: Figure 3 The diagram shown is a flowchart illustrating the process of determining the scatter data that can be displayed in the display area based on the adaptive base map adjustment scheme of this application.

[0048] Determining the scatter data that can be displayed in the display area includes at least the following steps:

[0049] S301, Determine the display area based on the target location and display radius;

[0050] S302, based on the specified image display size and display distortion degree corresponding to the scatter data, determine the number of data to be displayed in the display area;

[0051] S303, determine the amount of scattered data that can be displayed within the display area based on the density of the scattered data and the number of data to be displayed;

[0052] In S301, the display area that the magnifying glass can display is determined based on the display radius, with the target location as the center. Here, the magnifying glass can be a fisheye magnifying glass, or other types of magnifying glasses.

[0053] In S302, the image display size corresponding to each scatter point in the scatter data can be the same or different; there are no strict limitations here. Generally, once the magnifying glass is determined, its magnification is also determined. Magnification corresponds to the degree of distortion; when the magnifying glass is determined, the degree of distortion is also determined.

[0054] The formula for calculating the number of data N displayed within the display area is as follows (1):

[0055]

[0056] Where W represents the area of ​​the display area, P represents the display distortion of the display area, S represents the specified image display size corresponding to the scatter data, and E, C, and D are all constants.

[0057] In step S303, for any scattered data point within the area corresponding to the target location, the distance between the scattered data point and the target location is determined; the scattered data points are sorted according to the order of their distances; the scattered data points with the smallest distances in the sorting result are designated as scattered data points to be displayed as images within the display area; the scattered data points other than the scattered data points with the smallest distances in the sorting result are designated as scattered data points to be displayed as scattered points. For example: the scattered data points are sorted in ascending order of distance, the top N scattered data points in the sorting result are added to the image display list, and the scattered data points in the image display list are used as scattered data points to be displayed as images within the display area. The other scattered data points besides the top N scattered data points in the sorting result are added to the scattered point display list, and the scattered data points in the scattered point display list are used as scattered data points to be displayed as scattered points outside the display area.

[0058] In a preferred embodiment, for step S203, the magnification and display position of the scatter data can be adaptively adjusted based on the scaling factor of the base map; specifically as follows: Figure 4 The diagram shown is a flowchart illustrating the process of determining the magnification factor and display position of scattered data in the adaptive base map adjustment scheme of this application.

[0059] Determining the magnification factor and display position of scatter data involves at least the following steps:

[0060] S401, for any scattered data point within the display area: determine the first display position of the scattered data point based on the scaling factor of the background image on the display area; calculate the distance between the first display position and the target position, and determine the magnification factor of the scattered data point based on the distance and the display distortion; determine the second display position of the scattered data point based on the magnification factor and the first display position.

[0061] S402, based on the scaling factor of the background image on the display area, calculate the scatter point display position of each scatter point data in the scatter point data displayed in scatter point form outside the display area.

[0062] The magnification of the scatter plot data is inversely proportional to the distance (the distance between the first display position and the target position). The magnification of the scatter plot data is greatest at the target position, which is the distortion of the display like a magnifying glass; the magnification of the scatter plot data around the target position gradually decreases as the distance from the target position gradually increases. The magnification of each scatter plot data point within the display area is uncertain.

[0063] The scaling factor of the background image in the display area is the same for each scatter point. Because the scaling factor of the background image in the display area varies, the positions of all scatter points within the display area will change, including those in the image display list and the scatter point display list.

[0064] It should be noted that the algorithm used to calculate the second display position of the scattered data within the display area and the magnification of the scattered data is the magnifying glass distortion algorithm.

[0065] At the zoom level of the display area's base map, the N scattered data points within the display area are displayed at their respective magnification levels in their new positions; the scattered data points outside the display area are displayed as scattered points in their new positions.

[0066] This application embodiment enables the visualization of large-scale image data by adaptively controlling the amount of data displayed within the display area and the scaling factor of the base map, thereby improving the visualization effect of big data and solving the problem of resource waste caused by the inability to view image data due to the large amount of data loaded.

[0067] The following section will provide a detailed explanation of the adaptive adjustment of the base map as a method for displaying image data, using specific applications as examples.

[0068] First, based on the display radius R, image display size S, and display distortion P, the number of data points N to be displayed within the display area is automatically calculated. Then, with the current mouse point as the center, the scaling factor of the background image in the display area is automatically calculated when displaying N data points within the display radius R. Finally, with the background image scaling factor determined, the N scattered data points within the R range are displayed as data images at their respective magnification factors and new positions, while other scattered data points are still displayed as scattered points at their new positions.

[0069] The specific process is as follows:

[0070] Step 1: Set the display distortion P; display radius R; image display size S.

[0071] Step 2: Calculate the number of data N displayed in the display area according to formula (1).

[0072] Step 3: Based on the feature region W' of the N data points to be displayed in the image and the display area W of the N data points, calculate the scaling factor L of the background image of the display area.

[0073] Step 4: Based on the magnifying glass distortion algorithm, calculate the magnification factor of each of the N data points of the image to be displayed, as well as the new position of each of the N data points of the image to be displayed.

[0074] Step 5: Obtain images of N data points and display them at a new location with a specified magnification.

[0075] Step 6: Based on the scaling factor L of the base map, calculate the new location of other scattered data outside the display area, and display the scattered data at the new location.

[0076] The visualization of image data is achieved by adaptively adjusting the display radius.

[0077] like Figure 5 The diagram shown is a flowchart illustrating a method for displaying image data based on an adaptive adjustment of the display radius, according to another embodiment of this application.

[0078] The embodiments of this application are as follows: Figure 1 This method for displaying image data based on an adaptive adjustment of the display radius is further optimized from the previous embodiment and includes at least the following steps:

[0079] S501, based on the trigger of the target location within the display area, obtain the density of scattered data in the area corresponding to the target location;

[0080] S502, at least based on the density of the scattered data, determine the scattered data that the display area corresponding to the target location can display; wherein, the display area is a part of the display area;

[0081] S503, determine the display radius of the display area, so as to display the scattered data that can be displayed in the form of images within the display area.

[0082] Among them, steps S501 and S502 are respectively with Figure 1 The processes of steps S101 and S102 are similar and will not be repeated here.

[0083] In step S503, while keeping the size of the display area base map unchanged, the size of the display radius is adaptively adjusted so that the scattered data within the display area are displayed at their respective new positions with their respective magnifications; the scattered data outside the display area are displayed in their original positions in the form of scattered points.

[0084] In a preferred embodiment, for step S502, the scatter data that the display area corresponding to the target location can display can be determined based on the display distortion of the display area, the specified image display size corresponding to the scatter data, and the density of the scatter data. Specifically, as follows... Figure 6 The diagram shown is a flowchart illustrating the process of determining the scatter data that can be displayed in the display area in the adaptive adjustment display radius scheme of this application.

[0085] Determining the scatter data that can be displayed in the display area includes at least the following steps:

[0086] S601, determine the display radius based on the display distortion, the specified image display size corresponding to the scatter data, and the density of the scatter data;

[0087] S602, determine the display area based on the target location and display radius, so as to determine the scattered data that can be displayed in the display area.

[0088] In S601, the formula for calculating the radius R is shown in equation (2) below:

[0089]

[0090] Where P represents the display distortion of the display area, and S represents the specified image display size corresponding to the scatter data. This represents the density of the scatter data; F, C, and D are all constants.

[0091] In S602, the location information of any scattered data within the area corresponding to the target location is obtained; it is determined whether the location information of the scattered data is located within the display area; if the scattered data is located within the display area, it is determined to be scattered data displayed in the form of an image within the display area; if the scattered data is located outside the display area, it is determined to be scattered data displayed in the form of scattered points outside the display area.

[0092] For example: For each scatter data point within the target location area, determine whether the location information of the scatter data point is within the display area. Add the scatter data point within the display area to the image display list, and add the scatter data point outside the display area to the scatter display list. The scatter data point in the image display list is displayed as an image in the display area, and the scatter data point in the scatter display list is displayed as a scatter point outside the display area.

[0093] In a preferred embodiment, for step S503, the magnification and display position of the scattered data can be adaptively adjusted based on the display distortion of the display area and the position of the scattered data within the display area. Specifically, as described below, determining the magnification and display position of the scattered data based on the adaptive adjustment of the display radius scheme of this application includes at least the following steps:

[0094] For any scattered data point within the display area: determine the distance between the scattered data point and the target location; determine the magnification factor corresponding to the scattered data point based on the distance and the display distortion; determine the display position of the scattered data point based on the magnification factor and the location information of the scattered data point.

[0095] For any scattered data point outside the display area: display the scattered data point in its original location.

[0096] The magnification factor corresponding to scatter data is inversely proportional to the distance (the distance between the scatter data and the target position).

[0097] It should be noted that the algorithm used to calculate the display position of scattered data within the display area and the magnification of the scattered data is the magnifying glass distortion algorithm.

[0098] Therefore, scattered data within the display area are displayed as data images at a specific magnification in the new display location, while scattered data outside the display area are displayed as scattered points in the original location.

[0099] The following section will provide a detailed explanation of the method for adaptively adjusting the display radius to display image data, using specific applications as examples.

[0100] First, using the current mouse point as the center, calculate the density of the scatter data. Based on the density of the scatter data Given the image display size S and display distortion P, calculate the display radius R. Then, with the current mouse point as the center, display the scattered data within the radius R as images at the new location with their respective magnifications, while other scattered data remain displayed as scattered points in their original locations.

[0101] The specific process is as follows:

[0102] Step 1: Set the display distortion P; image display size S.

[0103] Step 2: Calculate the density of the scatter data.

[0104] Step 3: Based on formula (2), determine the density of the scatter data. Given the image display size S, display distortion P, calculate the display radius R.

[0105] Step 4: For any scatter data point: Based on the location information of the scatter data point, detect whether the scatter data point is within the display area. If not, it will still be displayed in the original location as a scatter point.

[0106] Step 5: If the scattered data is within the display area, then calculate the magnification of the scattered data and its new position based on the magnifying glass distortion algorithm.

[0107] Step 6: Obtain an image of the scatter data of the display area and display it at the new location with a specified magnification.

[0108] This application implements adaptive adjustment of the display radius of the display area, thereby controlling the display range and the amount of display data, thus enabling the visualization of large-scale image data, improving the visualization effect of big data, and solving the problem of resource waste caused by the inability to view image data due to the large amount of scattered data loading.

[0109] It should be understood that in the various embodiments of this application, the sequence number of each process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
