Slope Landmark Classification for Indoor Vehicle Floor Detection

Indoor vehicle floor detection is an important technology for building a smart parking system. Conventional indoor floor detection methods are impractical because they are limited to the sites where infrastructure such as cameras, beacons, and sensors are installed. In this paper, we introduce indoor vehicle floor detection technology with smartphone sensors. The proposed technology is highly practical because it does not require installation of additional infrastructures for vehicles and parking lots to detect indoor floors of the vehicle. The experimental result shows that our approach detects vehicle’s floor with an average accuracy of 89.2% based on a single-floor reference.
