Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic control systems are limited by incompatible data across multiple systems, requiring manual conversion to real-time applications and lack accurate real-time object detection and tracking.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional traffic control systems use sensors to detect vehicles and traffic, then traffic monitoring capability is provided, but the systems are limited to tracking objects from a point of view of a sensor and the data from different systems are not compatible for real-time applications
Solution Approach 1:
The patent introduces a coordinate transformation module as an intermediary that converts sensor coordinates to GPS coordinates, enabling compatibility between different systems (traffic control systems, vehicle navigation systems, etc.) without requiring complex direct integration between all systems
Solution Approach 2:
The patent transforms the tracking dimension from a 2D sensor point-of-view to a 3D GPS coordinate system, allowing objects to be tracked in the real-world coordinate system rather than being confined to the sensor's limited field of view, thereby enabling multi-system compatibility
2Reliability
If manual conversion of data between systems is performed, then data compatibility is achieved, but real-time processing capability is lost
Solution Approach 1:
The coordinate transformation module automatically performs the conversion from sensor coordinates to GPS coordinates without requiring manual intervention, enabling real-time data processing while maintaining compatibility across different systems
Solution Approach 2:
The system pre-establishes the coordinate transformation parameters and models before actual data processing occurs, allowing for instant conversion of incoming data without time-consuming manual conversion steps
3Measurement precision
If sensors track objects from a fixed point of view, then local traffic monitoring is achieved, but accurate real-time mapping to real-world coordinates is not possible
Solution Approach 1:
The patent transitions from 2D sensor-based tracking to 3D GPS coordinate mapping, enabling precise real-world location identification while making the data more interpretable by referencing familiar map coordinates rather than sensor-specific coordinate systems
Solution Approach 2:
The coordinate transformation module serves as an intermediary that bridges the gap between sensor coordinates and real-world GPS coordinates, maintaining measurement precision while improving ease of interpretation through familiar mapping references

AI summary
Systems and methods for tracking objects though a traffic control system include an image sensor configured to capture a stream of images of scene from an associated real-world position, an object tracker configured to identify an object in the captured images and define an associated object location in the captured images, a three-dimensional stage model system configured to transform the associated object location in the image to three-dimensional coordinates associated with the image sensor, and a three-dimensional world model configured to transform identified objects to real-world coordinates. Embodiments use lens aberration, sensor mounting height and location, accelerometer, gyro-compass and/or global position satellite information to generate a situational map.
