Researchers at the Indian Institute of Technology (IIT) Madras have developed a groundbreaking, real-time indoor mapping technology that can function effectively in challenging environments. UbiqMap, a portable system, creates accurate floor plans using radio frequency signals, without relying on existing infrastructure.
Key Features and Benefits
- Real-time imaging of indoor spaces using radio frequency signals
- Portable system with wearable transceivers for continuous tracking of movement and location
- Minimal reliance on visual line of sight and computing resources
- Identifies material properties of building components, aiding responders in route planning and safety assessments
- Designed for affordability and adaptability, working with existing systems like cameras and SLAM tools
The system, named UbiqMap, employs Radio Tomographic Imaging (RTI), a technique that uses radio frequency signals to generate accurate floor maps. Unlike traditional RTI systems that depend on a fixed network of wireless transceivers, UbiqMap introduces a dynamic system using wearable transceivers.
Ayon Chakraborty, assistant professor in the Department of Computer Science and Engineering, led the project. “This technology addresses a crucial challenge in disaster management—access to accurate and up-to-date indoor maps, which are often unavailable or outdated during emergencies,” he said.
Testing and Future Developments
The UbiqMap system was tested successfully within controlled settings on the IIT-Madras campus, demonstrating reliable imaging of indoor spaces. The team is now working on enhancing the technology by balancing radio frequency choices for optimal resolution and indoor penetration, integrating visual inputs through sensor fusion, and developing a wearable prototype for real-world field trials.
A patent has been filed for the technology, and the research has been peer-reviewed and published in the IEEE Transactions on Mobile Computing.
Applications and Potential Impact
UbiqMap stands out among existing mapping solutions due to its independence from visual line of sight and low reliance on computing resources. This makes it particularly valuable in cluttered, poorly lit, or structurally compromised environments. It can also identify material properties of building components, aiding responders in route planning and safety assessments.
Designed for affordability and adaptability, the technology can work in tandem with existing systems like cameras and SLAM tools, further enhancing its performance. By providing first responders with real-time situational awareness, UbiqMap is poised to become a vital tool in managing high-risk, time-sensitive operations.
In future applications, the system could benefit smart building management, indoor robotics, and warehouse navigation, offering scalable solutions for both emergency and commercial use cases.
Conclusion
UbiqMap, the real-time indoor mapping technology developed by IIT Madras researchers, has the potential to revolutionize disaster response and public safety missions. With its ability to create accurate floor plans in challenging environments, UbiqMap is poised to become a vital tool in managing high-risk, time-sensitive operations.
