Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map display technologies struggle to effectively simulate three-dimensional geological features on electronic maps, resulting in a reduced display effect due to elongated building representations that do not accurately depict real three-dimensional features.
Innovation Solution
A method and apparatus for displaying maps that determine and display three-dimensional geological features using a shared three-dimensional model and display style data, which includes display position, angle, and size information, to accurately simulate and enhance the display of these features on electronic maps.

Engineering Contradiction Analysis
1Ease of manufacture
If buildings are elongated based on display outline (cube to cuboid), then the display process is simplified, but the three-dimensional geological feature simulation effect is reduced
Solution Approach 1:
The patent uses three-dimensional model data to copy and reconstruct the actual geological features on the electronic map. Instead of simplifying buildings to basic cuboids, the system retrieves and renders detailed three-dimensional models that accurately replicate the real-world geological features, thereby maintaining high simulation accuracy while streamlining the display process through automated model retrieval and positioning.
Solution Approach 2:
The patent transforms the display approach by changing from geometric simplification (elongating cubes to cuboids) to parameter-driven rendering. It uses three-dimensional coordinate data, elevation information, and model parameters to dynamically adjust the display of geological features, enabling accurate three-dimensional representation without manual simplification while improving display efficiency through automated parameter application.
2Manufacturing precision
If three-dimensional models are used to simulate geological features, then the display effect is improved, but the data processing complexity increases
Solution Approach 1:
The patent implements a universal three-dimensional model management system that handles multiple types of geological features (buildings, mountains, water bodies) using a common data structure and rendering pipeline. The system retrieves three-dimensional models from a centralized database, applies unified coordinate transformations, and uses consistent rendering parameters, thereby reducing data processing complexity while maintaining high display quality across diverse geological features.
Solution Approach 2:
The patent introduces an intermediary layer consisting of a three-dimensional model database and a coordinate transformation module. This intermediary system acts as a mediator between the raw geographic data and the final display, automatically handling the complex tasks of model retrieval, coordinate conversion, and parameter adjustment. This intermediary architecture simplifies the overall data processing workflow while enabling high-quality three-dimensional visualization.

AI summary
This application relates to the field of map technologies, and may be applied to the field of an in-vehicle scene and a map. Three-dimensional geological features included in a to-be-displayed area is determined in response to a display instruction for a to-be-displayed area in an electronic map, the plurality of three-dimensional geological features corresponding to a same shared three-dimensional model. The shared three-dimensional model and display style data of the three-dimensional geological features is obtained. The to-be-displayed area on the electronic map is displayed, and a to-be-displayed three-dimensional geological feature of the plurality of three-dimensional geological features is displayed in the to-be-displayed area based on the shared three-dimensional model and the display style data of the plurality of three-dimensional geological features.
