Radar-Camera Object Matching for Reliable Monitoring Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems face challenges in accurately detecting objects within a monitoring area, as the detection by one unit (object detection or imaging) may fail to trigger alarms when the other unit cannot detect the object, leading to inaccuracies in object positioning.
Innovation Solution
A monitoring system comprising a radar and at least one camera that collaboratively determine whether detected and imaged objects are identical by using radar and imaging position information, generating attribute information, and providing notification based on this determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the object detection unit triggers the setting of an inspection area, then the imaging unit can capture the object, but if the object detection unit cannot detect the object, then an alarm cannot be activated and detection accuracy deteriorates
Solution Approach 1:
The patent combines radar detection and camera imaging into an integrated monitoring system where both units operate simultaneously on overlapping monitoring areas. The radar detection unit and camera imaging unit work together to detect and identify objects, with their results cross-referenced to improve both detection accuracy and alarm reliability. This merging eliminates the dependency where one unit must trigger the other, allowing independent verification of object presence.
2Measurement precision
If radar and camera monitor overlapping areas, then object detection accuracy improves, but system complexity increases
Solution Approach 1:
The patent introduces a determination unit as an intermediary component that receives detection results from both the radar detection unit and camera imaging unit. This determination unit processes and correlates the data from both sources, determining whether detected objects are identical or different. By centralizing the integration logic in this intermediary unit, the system manages complexity while maintaining high detection accuracy through multi-source verification.

Function Achieved in This Case
Improves detection accuracy by ensuring that objects are correctly identified and tracked within the monitoring area, enabling precise object positioning and attribute recognition.
Implementation Method 1
a radar including an antenna unit configured to transmit an electromagnetic wave to a first monitoring area and receive a reflected wave of the electromagnetic wave
Data Source
AI summary
A monitoring system determines whether or not a detected object and an imaged object are an identical object on the basis of radar position information and imaging position information and notifies a user terminal of notification information. The notification information is, in a case where it is determined that the detected object and the imaged object are an identical object, information in which a first identifier for identifying the detected object, detected object attribute information, a camera image, and imaged object attribute information are associated together and is, in a case where it is determined that the detected object and the imaged object are not an identical object, information based on at least one of radar installation position information, detected object attribute information, imaging position information, or imaged object attribute information.
