Abstract
A device for detecting a parking space includes: a signal pre-processing unit configured to filter ultrasonic signals emitted from ultrasonic sensors attached to a vehicle, and reflected and returned from a corner section of an obstacle; a corner estimating unit configured to extract a crossing point of a plurality of circles each having a measurement distance as a radius, wherein the measurement distances are collected from the received ultrasonic signals according to a movement of the vehicle, estimate a reflection angle between a first line for bisecting a detection region of the ultrasonic sensor, which has an attachment position of the ultrasonic sensor as a reference point, and a second line for connecting the reference point and the crossing point, and estimate the corner section based on the estimated reflection angle; and a parking space detecting unit configured to detect a parking space according to the estimated corner section.
