Progressive online high-precision map service engine system

Abstract

The invention discloses a progressive online high-precision map service engine system which comprises a data assembly module, a computing power collaboration module and a rendering editing module. The data assembly module is used for organizing and storing the high-precision map vector data of an original source; constructing a high-precision graph spatial index according to a global subdivision grid mode, performing high-precision map illustration according to a graph-data loose coupling mode, and checking the transmission accuracy of the end-to-end data; the computing power collaboration module is used for carrying out collaboration utilization and balance scheduling on the computing power resources of a server side and a client side of the engine system, finely controlling the transmission of a high-precision map object and displaying a time sequence; and the rendering editing module is used for compiling the components of a high-precision map illustration scheme according to the balance scheduling of the computing power collaboration module on the high-precision map object data and performing editable rendering display. The system has the remarkable effect that the service problems of online transmission, display, analysis and the like of the mass spatial graphic data of the high-precision map are solved.

Description

technical field [0001] The invention relates to the technical field of geographic information services, in particular to a high-precision map-oriented online service engine system that adopts schedulable, programmable, and progressive technical methods. Background technique [0002] With the continuous advancement of automobile automatic driving technology, automatic driving has gradually been applied in experiments and specific environments, and high-precision maps are one of the basic technologies supporting automatic driving applications, and are widely used in electronic navigation, Internet maps and other fields. application. The difference between high-definition maps and traditional electronic maps is that the former has higher map data accuracy, and has more detailed, accurate, and high-fidelity map element objects. Due to the above characteristics of high-precision maps, high-precision maps have the characteristics of large data volume, complex graphics, and the ne...

Problems solved by technology

This method needs to be equipped with a large number of hardware computing resources on the server side, and the investment cost is high, and there is a lot of redundancy in server resources, and the computing resources of the client side are not fully utilized to share the burden of the server.

[0005] The above two technical methods ultimately use pictures to display electronic maps. When it is necessary to analyze spatial objects, it cannot be analyzed directly based on pictures. It is necessary to call the background vector data for analysis and calculation, which naturally separates image display and data analysis. , causing a lot of inconvenience to the practical application

[0006] The above two technical methods are difficult to meet the needs of applications such as intelligent navigation and unmanned driving when facing high-precision map services
