Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video monitoring systems using radar and fixed location imaging devices often result in false alarms due to environmental reflections and non-threatening targets, leading to increased human resources and costs for investigating potential threats.
Innovation Solution
The integration of an unmanned aerial vehicle (UAV) with a radar system that autonomously navigates to detected movement locations, captures images, and transmits them to a computing device for automatic recognition, reducing false alarms by supplementing image validation and potentially using a multi-hop network to increase communication range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a network of fixed location imaging devices is deployed to validate movement and reduce false alarms, then the accuracy of threat identification is improved, but the device complexity and cost increase
Solution Approach 1:
The patent transitions from static fixed location imaging devices to a dynamic mobile imaging device (UAV) that can autonomously navigate to detected movement locations. This dynamic approach allows a single mobile device to replace multiple fixed devices, reducing system complexity while maintaining the ability to validate movements and reduce false alarms through image capture and automatic recognition
Solution Approach 2:
The mobile imaging device on the UAV serves multiple functions: it navigates autonomously to event locations, captures images for validation, and transmits data for automatic recognition. This multi-functional device replaces the need for multiple specialized fixed imaging devices, reducing overall system complexity while improving measurement precision
2Area of stationary object
If multiple fixed location imaging devices are installed to cover the total area, then the area coverage is improved, but the cost and difficulty of installation increase
Solution Approach 1:
The patent employs a mobile imaging device that can dynamically reposition itself to cover different areas, replacing the need for multiple fixed devices. The UAV can fly to any location within the monitored area, providing flexible and comprehensive coverage without the installation complexity of deploying multiple fixed devices throughout the area
Solution Approach 2:
The mobile imaging device operates in three-dimensional space, allowing it to cover a larger area from elevated positions and adjust its viewing angles. This dimensional advantage enables a single device to cover the total area more effectively than multiple ground-level fixed devices, simplifying installation while maintaining comprehensive coverage
3Reliability
If fixed location imaging devices are used to capture images for validation, then false alarms are reduced, but the range and quality of image capture are limited
Solution Approach 1:
The mobile imaging device can dynamically approach detected movement locations to capture high-quality validation images, overcoming the limited range of fixed devices. By autonomously navigating close to the event, the mobile device ensures reliable image capture for false alarm reduction while achieving superior image quality and range compared to stationary devices
Solution Approach 2:
The mobile imaging device acts as an intermediary between the radar system and the final validation decision. It autonomously bridges the gap by navigating to detected locations and capturing images that confirm or refute potential threats, thereby reducing false alarms while achieving both extended range and high image quality that fixed devices cannot provide
