Dynamic 3D Ad Overlay on Navigation Building Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems display advertisements in a 3D environment using a jerky sequence of 2D images, which does not provide a realistic view and can confuse users by showing virtual objects that differ from the real world, especially when moving through a 3D world.
Innovation Solution
The system uses a vector-based 3D model of real-world objects to dynamically overlay messages, such as advertisements, on 3D objects like building facades and billboards, allowing for a realistic video-like view from different angles and integrating seamlessly with navigation data like road locations and attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a sequence of 2D images is used to display advertisements on 3D objects, then the advertisement can be shown on virtual objects, but the display appears jerky and does not provide a realistic view
Solution Approach 1:
The patent transitions from displaying advertisements on 2D images to displaying them on 3D objects in a three-dimensional environment. This dimensional change allows the advertisement to be rendered on the surface of 3D models (e.g., buildings, billboards) rather than on flat 2D images, providing a more realistic and immersive view that moves with the vehicle along the road.
2Adaptability or versatility
If virtual objects are displayed that differ from the real world, then advertisements can be shown on 3D objects, but users may be confused by the discrepancy
Solution Approach 1:
The patent applies local quality by displaying advertisements only on specific 3D objects (such as buildings or billboards) rather than altering all virtual objects. The 3D environment and other objects remain consistent with the real world, while only the designated advertisement surfaces are replaced, maintaining realism where it matters and avoiding user confusion.
3Productivity
If a jerky sequence of 2D images is used, then advertisements can be displayed on moving objects, but the view does not move naturally with the vehicle
Solution Approach 1:
The patent implements dynamics by rendering advertisements on 3D objects that move smoothly with the vehicle along the road. The 3D models and advertisements are updated continuously based on the vehicle's position, creating a seamless and natural viewing experience rather than a jerky sequence of static images.

AI summary
A method of and system for displaying information on a display are disclosed. In at least one embodiment, the method has the following actions: a) accessing a 3D model with 3D objects 5 b) showing on the display a graphical display of one or more scenes comprising a moving view on one or more of the 3D objects as seen from a certain moving point of view, the one or more 3D objects comprising at least one advertisement space, the at least one advertisement space having an advertisement space location and an advertisement space size, c) receiving a message inclusive of message data and message location data, and d) in dependence on a distance between the moving point of view and the one or more 3D objects, mapping the message data on the at least one advertisement space if the advertisement space location is associated with the message location data such that the message data overlays the advertisement space in the display.
