AI Technical Summary

Technical Problem

In the fields of geographic information systems and remote sensing, existing technologies, such as traditional tile map services, cannot achieve semantic understanding of data, resulting in storage waste and data update delays. Furthermore, deep learning inference capabilities are not seamlessly integrated into the standard tile request-response chain, leading to high latency in high-concurrency scenarios and the inability to achieve WYSIWYG intelligent map services.

Method used

Employing the lightweight MICP protocol, it achieves sub-millisecond collaborative scheduling of CPU rendering and GPU inference dual pipelines. It uses vector pyramid indexing technology for on-demand computation and combines the MICP protocol for task distribution and state synchronization, enabling parallel processing of raster tile real-time visualization and deep learning interpretation.

Benefits of technology

It significantly reduces the response latency and storage overhead of map services, enables online intelligent reasoning of remote sensing data with instant visibility, improves the timeliness of geospatial information acquisition and system operation and maintenance efficiency, and expands the interactive depth and analytical flexibility of map services.

Abstract

This invention discloses a real-time raster tile inference map service method and system, belonging to the fields of geographic information systems and remote sensing technology. The method includes a service system receiving tile requests, calculating the corresponding geospatial coordinate range based on the tile requests, reading the original data block covering the geospatial coordinate range from distributed storage, and distributing the original data block to the CPU rendering pipeline and GPU inference pipeline for parallel processing based on the MICP protocol. The MICP protocol is an application-layer protocol specifically used for task distribution and state synchronization between the computing scheduling unit and the intelligent inference engine. It fuses the visual base map generated by the CPU rendering pipeline with the intelligent interpretation result generated by the GPU inference pipeline and returns it as a service response. This invention achieves real-time raster tile rendering and intelligent inference parallel processing based on the MICP protocol, providing a WYSIWYG map service.
