[0002] In the current data visualization field, many solutions rely on traditional drawing algorithms and data processing pipelines. These software are usually designed to handle a certain number of drawing nodes, each of which represents an element or object in the drawing. When the user modifies the content of a node, the software triggers a redrawing process to ensure that the displayed content is consistent with the data model.

[0003] Existing real-time data visualizations often adopt a full update strategy when processing drawing nodes. This means that every content change, regardless of the scope of the change, will result in the redrawing of all related nodes. Although this method is simple and direct, it will cause significant performance problems when faced with a large number of drawing nodes that do not interfere with each other. Existing real-time data visualizations do not have an effective mechanism to distinguish which nodes have actually undergone content changes, so targeted local updates cannot be achieved. This not only adds unnecessary computing burden, but may also lead to a waste of system resources, especially in resource-constrained environments.

The specific settings can be made according to the situation, and the embodiments of the present invention are not limited here. The method of obtaining the historical signal data of the vehicle in step S101 can be to obtain the historical signal data set of the vehicle according to the signal acquisition device, or to call the historical signal data set stored in the storage medium. The real-time signal data of the vehicle can be obtained through vehicle sensors, cameras and other devices. The specific historical signal data and real-time signal data can be set according to the situation, and the embodiments of the present invention are not limited here.

[0021] In a specific embodiment of the present invention, the historical signal data may include multiple signal parameters, such as angle, speed, etc. After obtaining the historical signal data and real-time signal data of the vehicle, the historical data can be analyzed and processed to obtain at least one graphic element of the multiple signal parameters, that is, a graphic element for each signal parameter, such as a graphic element corresponding to the angle; then the historical signal data and the real-time signal data can be compared item by item, so that it can be determined based on the comparison result whether the data of multiple signal parameters in the real-time signal data have changed. If so, at least one signal data to be updated can be determined, and then the target graphic element corresponding to each signal data to be updated can be determined, and then the target graphic element can be recalculated and rendered according to each signal data to be updated to obtain the real-time updated signal data of the vehicle, thereby completing the optimization of the real-time vehicle signal display.

[0022] Compared with the prior art, the present embodiment provides a method for obtaining historical signal data and real-time signal data of a vehicle; the historical signal data includes multiple signal parameters; at least one graphic element of the multiple signal parameters is obtained based on the historical signal data; the historical signal data and the real-time signal data are compared item by item to determine at least one signal data to be updated, and a target graphic element corresponding to each signal data to be updated is determined; the target graphic element is recalculated and rendered based on each signal data to be updated to obtain the real-time updated signal data of the vehicle; the present invention divides the signal parameters of the vehicle into multiple graphic elements, and when there is signal data to be updated in the real-time signal data of the vehicle, the target graphic element is determined by matching the signal data to be updated with the multiple graphic elements, so that the target graphic element can be recalculated and rendered, thereby achieving targeted local updates and reducing unnecessary computing burdens.

[0023] In some embodiments of the present invention, at least one graphic element includes at least one high-frequency graphic element and at least one low-frequency graphic element; Figure 2 , step S102 includes: S201, drawing an initial graphic element corresponding to each signal parameter according to a plurality of signal parameters; S202, analyzing historical signal data to obtain the usage frequency of the initial graphic element of each signal parameter; S203: Screen the initial graphic elements according to the usage frequency to determine at least one high-frequency graphic element and at least one low-frequency graphic element.

[0024] In a specific embodiment of the present invention, after obtaining the historical signal data, the initial graphic elements corresponding to each signal parameter can be drawn through drawing software based on multiple signal parameters in the historical signal data. For example, the initial graphic elements may include various vehicles, various signs and other picture elements; this step can be drawn and stored before S101 to facilitate subsequent use, and then the historical signal data can be analyzed to obtain the frequency of use of the original graphic elements of each signal parameter in the historical signal data.

[0025] In some embodiments of the present invention, Figure 3 As shown, step S203 includes: S301, determining whether the usage frequency of each graphic element is greater than a preset threshold; S302: If yes, determine that the graphic element is a high-frequency graphic element, and obtain at least one high-frequency graphic element; S303: If not, determine that the graphic element is a low-frequency graphic element, and obtain at least one low-frequency graphic element.

[0026] In a specific embodiment of the present invention, after obtaining the usage frequency of the graphic element, the usage frequency of each graphic element can be judged to determine whether the usage frequency is greater than a preset threshold. The specific preset threshold can be set according to actual conditions, and the embodiment of the present invention is not limited. Then, the graphic element with a usage frequency greater than the preset threshold can be determined as a high-frequency graphic element, and the graphic element with a usage frequency not greater than the preset threshold can be determined as a low-frequency graphic element, and then at least one high-frequency graphic element and at least one low-frequency graphic element can be obtained.

[0027] In some embodiments of the present invention, after step S203, the method further includes: A first unique identifier corresponding to each high-frequency graphic element is determined according to the graphic data of at least one high-frequency graphic element.

[0029] Furthermore, after acquiring the real-time signal data, the real-time signal data can be stored in a cache library, and it can be ensured that the data structure type of the real-time signal data is consistent with the historical signal data. Then, the historical signal data and the real-time signal data can be compared item by item, wherein the item by item comparison can be a comparison of specific data, such as the angle and speed of the vehicle offset signal. If it is found that a specific value in the historical signal data and the real-time signal data has changed, this signal data in the real-time signal data is marked as signal data to be updated, and then at least one signal data to be updated can be obtained.

The target graphic element can include a target low-frequency graphic element, and the corresponding graphic element can be determined according to at least one signal data to be updated, so as to determine the target low-frequency graphic element in the graphic element that is at least one low-frequency graphic element.

[0034] Furthermore, after obtaining the target graphic elements of each signal data to be updated, the corresponding target graphic elements can be recalculated and rendered according to each signal data to be updated, and only the changed parts are updated to obtain the real-time updated signal data of the vehicle, and the updated graphic elements are drawn on the display screen to achieve optimization of real-time vehicle signal display.
