AI Technical Summary

Technical Problem

Existing technologies cannot meet the requirements for efficient and smooth map display in scenarios with large-scale markers, resulting in high computational overhead, wasted resources, and poor user interaction experience.

Method used

By dividing the target grid within the display area, generating grid cache keys, and utilizing precise matching and proximity matching between grid cache keys and historical cache keys, effective labeled views can be quickly identified and reused, reducing the need for repeated view creation and update operations.

Benefits of technology

Significantly reduces CPU computational overhead and memory usage, improves the smoothness and stability of map annotation display, and ensures that the map maintains low latency and efficient display in scenarios with frequent interactive operations.

Abstract

本发明涉及地图数据技术领域，特别是一种地图数据的聚合方法、系统、电子设备和存储介质。该方法包括：获取电子设备显示范围，筛选出可显示点数据；根据可显示点数量将显示范围划分为多个目标网格，为各网格添加唯一标识并获取坐标范围，生成网格缓存键。生成聚合结果对象，包含网格缓存键及对应聚合标注点的信息。获取历史标注视图，按显示范围筛选出有效标注视图并获取其历史缓存键；逐一对聚合标注点匹配历史缓存键，匹配成功则复用有效标注视图为目标视图，失败则标记为待新建视图标注点。基于待新建点信息生成新建标注视图，结合目标视图与新建标注视图，最终生成聚合视图。本发明能保持流畅、稳定、低延迟的运行效果。
