Virtual Image Sensor Simulation for Alarm Scenario Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for testing image sensors in alarm systems are limited by the inability to recreate complex and disruptive environmental conditions, such as weather scenarios, and cannot effectively simulate unusual situations before the system is installed, leading to inadequate evaluation of sensor effectiveness.
Innovation Solution
The method involves creating simulation data by merging image sensor data with virtual object movement data to generate accurate simulation data that can be used to test the effectiveness of image sensors in various conditions, allowing for efficient evaluation of the alarm system's response to both normal and unusual situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real environmental conditions are used for testing image sensors, then the testing reflects actual system performance, but the testing cannot be performed before system installation and cannot recreate complex weather scenarios
Solution Approach 1:
The patent creates virtual copies of real-world environmental conditions through simulation data. Image sensor model data is generated that replicates the optical properties and sensor responses under various weather conditions (rain, snow, fog, different lighting) without requiring physical presence of these conditions. This allows comprehensive testing before installation while maintaining reliability through accurate virtual modeling.
Solution Approach 2:
The patent enables preliminary testing by generating image sensor model data in advance of actual system installation. The simulation framework allows evaluation of sensor performance under multiple environmental conditions before the physical sensor is deployed, enabling proactive system optimization and validation without waiting for real-world deployment.
2Reliability
If physical recreation of unusual situations is performed, then the testing covers all real-world scenarios, but the process is time-consuming and requires physical access to locations
Solution Approach 1:
The patent creates virtual representations of unusual situations by generating simulation data that models object movements, environmental conditions, and sensor responses. Instead of physically recreating scenarios like break-ins, accidents, or severe weather events, the system uses computational models to replicate these situations, achieving comprehensive scenario coverage without physical constraints or time delays.
Solution Approach 2:
The patent replaces physical mechanical recreation of scenarios with computational simulation. Rather than physically moving objects, setting up physical environments, and manually testing sensor responses, the system uses software-based simulation to generate and evaluate sensor data under various unusual conditions, dramatically reducing testing time and eliminating physical access requirements.
3Reliability
If comprehensive environmental conditions are simulated, then the evaluation covers all edge cases, but the data processing and simulation complexity increases
Solution Approach 1:
The patent divides the complex simulation task into separate manageable components: image sensor model data generation, environmental condition modeling, object movement simulation, and alarm situation evaluation. Each component can be independently configured, tested, and optimized. This modular approach allows comprehensive evaluation while managing complexity through systematic decomposition of the simulation framework.
