Title:
METHOD AND APPARATUS FOR PROXIMITY DETECTION AND PROXIMITY DIRECTION ESTIMATION
Document Type and Number:
WIPO Patent Application WO/2023/200276
Kind Code:
A1
Abstract:
An apparatus for estimating a proximity direction of an obstacle includes an acoustic transmitter attached to a surface of the apparatus; a first acoustic receiver spaced apart from the surface of the apparatus; a second acoustic receiver spaced apart from the surface of the apparatus; and at least one processor configured to: control the acoustic transmitter to generate an acoustic wave along the surface; obtain first and second proximity direction signals based on first and second acoustic wave signals corresponding to the generated acoustic wave; and estimate a proximity direction of the obstacle with respect to the apparatus based on the first and second proximity direction signals.
