Real-time visualization of domain coverage by dynamically moving sensors

Area of Science:

• Robotics and Sensor Networks
• Computer Vision and Graphics

Background:

• Effective monitoring of sensor coverage in dynamic environments is crucial for applications like autonomous navigation and surveillance.
• Existing methods often lack real-time feedback or detailed visualization of sensor visibility.

Purpose of the Study:

• To develop a real-time system for visualizing sensor visibility within an environment.
• To enable operators to monitor and control sensor movements effectively based on coverage data.

Main Methods:

• Implementation of two ray-tracing-based algorithms for visibility calculation.
• Development of interactive visualizations for preattentive detection of sensor coverage.
• Utilization of a GPU (Graphics Processing Unit) implementation with CUDA (Compute-Unified Device Architecture) for real-time processing.

Main Results:

• Real-time monitoring of the visible and non-visible portions of an environment by sensor subsets.
• Visualization allowing preattentive detection of sensor coverage at any location.
• Identification of individual sensors through distinct coloring schemes.

Conclusions:

• The developed system provides efficient, real-time environmental monitoring for sensor networks.
• The visualization tools enhance operator situational awareness and control over sensor operations.
• GPU acceleration significantly improves processing and display capabilities for dynamic scenes.
