报告摘要:
In recent years we have witnessed the rapid development of smart bicycles. For example, Mobike is able to interact with smartphones. As we all known, accurate bicycle localization system is one of the most critical technologies for the development of smart bicycles. However, GPS’s error is at meter-level and it performs poorly under skyscrapers and in tunnels.BikeLoc is a novel and accurate bicycle localization system that can achieve sub-meter location granularity without requiring fingerprinting of the environment. BikeLoc is based on a subtle combination of the wheel of a bicycle and Commercial Off-The-Shelf (COTS) Wi-Fi devices. The core design of BikeLoc is to leverage three antennas installed on one wheel to emulate large circular antenna arrays using Synthetic Aperture Radar (SAR). Previous work on circular SAR is based on the far-field assumption, which means the translation of the antenna array is limited and insignificant compared with the rotation. However, in bicycle’s application scenario, the translation and rotation are simultaneous and comparable. Our core contribution is the ability to perform SAR without the above assumption. We implement BikeLoc on a real bicycle and empirically demonstrate tens of centimeters localization accuracy for 3-D localization.
