Augmented Reality Map Overlay for Flood Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conditions such as floods or heavy snow, it is difficult for individuals to distinguish between road areas and water bodies, leading to potential accidents due to the lack of clear visual differentiation.
Innovation Solution
A system and method that overlays geographic map data onto a live feed using smart glasses or handheld devices, approximating fluid depth at fixed points and combining these readings with contour maps to generate a fluid depth map, which is then superimposed onto the live feed, creating an augmented reality image that enhances visibility and navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If geographic map data is overlaid onto a live feed to provide environmental information, then information completeness is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple data sources (live feed from camera, geographic map data, fluid depth data) into a single augmented reality display. The processing circuit merges these disparate information streams overlaying map contours and depth indicators on the real-world video feed, providing comprehensive environmental information while presenting it through a unified interface that the user perceives as a single integrated system.
2Measurement precision
If fluid depth approximation is performed on fixed points to calculate discrete depth readings, then measurement precision is improved, but loss of information increases
Solution Approach 1:
The patent creates a simplified representation of the continuous fluid depth field by measuring depth at discrete fixed points and then overlaying contour lines that represent equipotential depth values. Instead of processing every pixel for depth information, the system samples at specific points and generates a contour map that copies the essential depth information in a compressed, visually intuitive format that preserves measurement precision while reducing data processing requirements.

AI summary
A computer program product for overlaying geographic map data onto a live feed is provided. The computer program product includes a computer readable storage medium having program instructions embodied therewith. The program instructions are readable and executable by a processing circuit to cause the processing circuit to approximate fluid depth on fixed points in a live feed to calculate discrete depth readings, combine the discrete depth readings with a contour map associated with the live feed to generate a fluid depth map and combine the fluid depth map with the live feed to produce an augmented reality image including the fluid depth map superimposed onto the live feed.
