3D indoor positioning of UAVs with spread spectrum ultrasound and time-of-flight cameras
This work proposes the use of a hybrid acoustic and optical indoor positioning system for the
accurate 3D positioning of Unmanned Aerial Vehicles (UAVs). The acoustic module of this
system is based on a Time-Code Division Multiple Access (T-CDMA) scheme, where the
sequential emission of five spread spectrum ultrasonic codes is performed to compute the
horizontal vehicle position following a 2D multilateration procedure. The optical module is
based on a Time-Of-Flight (TOF) camera that provides an initial estimation for the vehicle …
