Augmented Reality Overlay for 3D Spatial Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing maps and applications for mobile devices are limited to two-dimensional displays that do not effectively show features that are not point features or are elevation-dependent, failing to provide users with comprehensive spatial information.
Innovation Solution
The development of systems and methods that overlay point, line, and elevation features onto a real-time camera view using a three-dimensional spatial database, integrating GPS, compass, and accelerometer data to display features in a user's current field of view, allowing for dynamic and interactive augmented reality experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two-dimensional map displays are used, then device complexity is reduced, but the ability to show elevation-dependent features and non-point features is limited
Solution Approach 1:
The patent transitions from two-dimensional map displays to three-dimensional augmented reality visualization by overlaying virtual features (point, line, and area features with elevation data) onto the real-world camera view. This allows elevation-dependent features to be displayed in their spatial context, resolving the contradiction between display versatility and system complexity.
2Loss of information
If three-dimensional spatial features are overlaid onto real-time camera view, then spatial information completeness is improved, but processing and integration complexity increases
Solution Approach 1:
The patent merges multiple data sources (GPS location, compass orientation, accelerometer data, and spatial database information) into a unified augmented reality display. By combining these elements into a single integrated system that processes and visualizes spatial features in context, the patent reduces information loss while managing integration complexity through unified processing.
3Measurement precision
If point, line, and area features with elevation data are displayed, then feature representation accuracy is improved, but computational requirements increase
Solution Approach 1:
The patent segments spatial features into distinct categories (point features, line features, and area features) with specific elevation dependencies. By dividing the complex spatial data into manageable segments with different rendering requirements, the system achieves high feature representation accuracy while optimizing computational energy consumption through selective processing of each feature type.

AI summary
A method for generating an augmented reality display on a display device according to embodiments of the present invention includes overlaying augmented reality data onto an actual image using three dimensional positioning data and three dimensional orientation data of the display device. The augmented reality data may include at least one line feature and/or at least one video feature, and may take into account both elevation of the device and the three-dimensional direction in which the imaging device is pointed.
