Solution Overview
Problem
Current navigation systems face challenges in effectively providing and displaying map and navigation information, particularly in illustrating routes in images with depth information, such as panoramic or street level views, which can be confusing due to the lack of accurate depth representation.
Innovation Solution
A system that receives image data correlated with a depthmap generated from an optical distancing system and route data calculated using a geographical database and routing algorithm, allowing for the insertion of navigation illustrations into the image data based on depth comparisons, enabling three-dimensional routing visualization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation information is provided using traditional 2D maps or lists, then the system is simple to implement, but the user experience is confusing and lacks accurate depth representation
Solution Approach 1:
The patent transitions from traditional 2D map representations to 3D spatial visualization by integrating depthmap data with panoramic images. Route points are projected onto the panoramic image plane using depth information, creating a three-dimensional routing visualization that preserves spatial relationships and provides accurate depth representation, directly resolving the information loss in traditional 2D displays
Solution Approach 2:
The system merges multiple data sources including panoramic images, depthmap data, and route calculation results into a unified navigation display. By combining these heterogeneous data types and integrating them into a single coherent visualization system, the patent achieves comprehensive spatial awareness without proportionally increasing system complexity
2Manufacturing precision
If navigation illustrations are inserted without depth consideration, then the processing is simple, but the routing visualization is inaccurate
Solution Approach 1:
The system performs preliminary depthmap generation and route point projection calculations before inserting navigation illustrations into the panoramic image. By pre-calculating the three-dimensional positions and projecting them onto the two-dimensional image plane using depth information, the system ensures accurate routing visualization while managing processing complexity through staged computation
Solution Approach 2:
The patent applies depth-based rendering selectively to route illustration elements, comparing the depth of each route point with the depth of underlying image features. This local quality approach ensures that navigation illustrations are rendered with appropriate transparency and positioning only where needed, achieving high visualization accuracy without uniformly increasing processing complexity across the entire system

Data Source
AI summary
One or more systems, devices, and/or methods for three dimensional routing are disclosed. For example, one embodiment includes receiving image data selected based on a viewer perspective from a memory. The image data is correlated with a depthmap generated from an optical distancing system and correlated with route data calculated from an origin point to a destination point using a geographical database and a routing algorithm. The controller compares a first distance, from the viewer perspective to a point correlated with the route data, to a second distance, derived from the depth map at the point. If the comparison indicates that the first distance is closer to the viewer perspective than the second distance, the controller inserts at least one pixel of a navigation illustration into the image data. The image data including the navigation illustration is transmitted to or stored in a memory.
