Overlaying 3D Building Models on Printed Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printed maps are limited to 2D representations, making it difficult for users to understand the topography and location of places, leading to confusion and potential getting lost during travel.
Innovation Solution
An electronic apparatus method that captures a printed map, defines a block area using image processing, queries a map service to find corresponding electronic map areas, and overlays 3D models of buildings onto the map, aligning them with the printed map's scale and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If printed maps are used for navigation, then portability and accessibility are improved, but spatial understanding and topography visualization deteriorate
Solution Approach 1:
The patent transforms 2D printed map information into 3D visual representations by overlaying three-dimensional building models onto the flat map surface. This dimensional transformation allows users to maintain the portability of printed maps while gaining enhanced spatial understanding through 3D building height representations, roof structure visualizations, and topographical depth perception that were impossible in traditional 2D format.
2Ease of manufacture
If 2D map representations are used, then simplicity and ease of production are improved, but user comprehension and navigation accuracy deteriorate
Solution Approach 1:
The patent introduces an intermediary layer of 3D building models that are superimposed onto the 2D printed map. This intermediary visualization layer acts as a bridge between the simple 2D map representation and the user's need for accurate spatial comprehension. The 3D models provide building height, volume, and structural information that enhance navigation accuracy without requiring the user to abandon the simplicity of printed maps.
3Adaptability or versatility
If traditional printed maps are used, then cost-effectiveness and accessibility are improved, but visual information richness and environmental understanding deteriorate
Solution Approach 1:
The patent adds a third dimension to traditional printed maps by overlaying 3D building models, thereby transforming flat 2D representations into visually rich three-dimensional visualizations. This approach maintains the cost-effectiveness and accessibility of printed maps while dramatically enhancing visual information richness through building height representations, spatial depth, and environmental context that help users better understand their surroundings.

AI summary
The invention discloses a method, an electronic apparatus, and a computer readable medium for retrieving a map. The method includes the following steps. Firstly, a picture of a printed map is obtained. A block area surrounded by a road outline in the picture is defined. A map service is queried to find an electronic map having a map area corresponding to the block area according to contents of the printed map. A plurality of 3-D models of a plurality of buildings located in the map area is retrieved. The 3-D models are mapped on the picture.
