Camera Feed Superimposition on Virtual Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic camera feed visualization methods, such as displaying thumbnails or conventional maps, fail to clearly indicate camera orientation and coverage, especially as the number of cameras increases, making it difficult for users to understand which direction a camera is facing and what street it is recording, and can be confusing when camera orientations change dynamically.
Innovation Solution
Superimposing camera feeds onto a two- or three-dimensional virtual map, allowing for alignment of camera feeds with map features, enabling users to understand camera orientation and coverage, and using a combination of manual and automatic alignment techniques to maintain accurate positioning and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional maps with icons are used to display camera locations, then the system can handle a large number of cameras, but it becomes difficult for users to understand camera orientation and coverage
Solution Approach 1:
The patent transitions from a two-dimensional icon-based map to a three-dimensional virtual globe representation. This dimensional enhancement allows camera feeds to be displayed in their actual geographic context, showing orientation and coverage area naturally through the 3D spatial representation, thereby resolving the information loss problem while maintaining the ability to handle multiple cameras
2Ease of manufacture
If static map icons are used, then the system is simple to implement, but it cannot dynamically reflect changing camera orientations
Solution Approach 1:
The patent implements a dynamic system where camera feeds are continuously updated and repositioned on the virtual globe based on current camera orientation and location data. The virtual camera representation rotates and repositions automatically as camera orientations change, providing real-time adaptability while maintaining system simplicity through automated processing
3Ease of operation
If multiple camera feeds are displayed separately, then each feed can be viewed in detail, but it becomes difficult for users to assimilate information from different feeds
Solution Approach 1:
The patent merges multiple camera feeds into a unified virtual globe display where all feeds are simultaneously visible in their correct geographic positions and orientations. Users can view individual feeds by selecting them while maintaining context of their spatial relationships, combining detailed individual viewing with comprehensive spatial awareness in a single integrated interface

AI summary
Feeds from cameras are better visualized by superimposing images based on the feeds onto map based on a two- or three-dimensional virtual map. For example, a traffic camera feed can be aligned with a roadway included in the map. Multiple videos can be aligned with roadways in the map and can also be aligned in time.
