Multi-Camera Traffic Violation Detection System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic violation detection systems face challenges in providing a 360° field of view without high bandwidth and expense, achieving detailed images of distant objects, and effectively using GPS location technology for comprehensive violation data, while also lacking side-looking cameras for improved position estimation and violation detection.
Innovation Solution
A system comprising multiple cameras, including wide-angle and narrow-angle cameras mounted on a law enforcement vehicle, which provides a 360° field of view, records and analyzes images in real-time to detect and document traffic violations, using GPS data and optical recognition software for evidentiary purposes, and includes a mechanism for issuing citations.

Engineering Contradiction Analysis
1Measurement precision
If very high resolution cameras are employed to achieve detailed images of distant objects, then image quality is improved, but bandwidth and expense increase significantly
Solution Approach 1:
The system segments the imaging function into two types of cameras: wide-angle cameras for general scene coverage and narrow-angle high-resolution cameras for detailed imaging of specific targets. This segmentation allows the system to achieve detailed images of distant objects without requiring all cameras to be high-resolution, thus reducing overall bandwidth and expense while maintaining measurement precision where needed.
2Measurement precision
If side looking cameras are added to improve position estimation and violation detection, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The side-looking cameras are integrated into the existing camera array system, serving multiple functions: they provide position estimation for vehicles, detect traffic violations such as passing on the wrong side, and contribute to the overall 360-degree field of view. This multi-functionality approach allows the system to achieve improved detection accuracy without proportionally increasing device complexity, as the same hardware infrastructure supports multiple detection objectives.

AI summary
A system mountable in a host vehicle, configured to operate while the host vehicle is moving in a road environment. The system includes a backward-looking camera with field-of-view behind the host vehicle, a side-looking camera with field-of-view to a side of the host vehicle, a forward-looking camera with field-of-view in front of the host vehicle. A processor is configured to control the cameras, to acquire and store in memory images acquired from the cameras. The processor is configured to detect a target vehicle in the images of a one camera and track a feature of the target vehicle in the images of the other cameras. A traffic violation is declared when a feature of the target vehicle is identified in images of the other cameras.
