Abstract

The present disclosure provides systems and methods associated with determining position and/or movement information using ultrasound. A system may include one or more ultrasonic transmitters and/or receivers. An ultrasonic transmitter may be configured to transmit ultrasound into a region bounded by one or more surfaces. The ultrasonic receiver may receive direct ultrasonic reflections and/or rebounded ultrasonic reflections from one or more objects within the region. A mapping or positioning system may generate positional data associated with one or more of the object(s) based on the direct ultrasonic reflection(s) and/or the rebounded ultrasonic reflection(s). The mapping or positioning system may generate enhanced positional data by combining the direct positional data and the rebounded positional data.
