METHOD AND APPARATUS FOR RECOGNIZING PARKING AREA

摘要

PURPOSE: A method and an apparatus for recognizing a parking space is provided to reduce measurement errors by processing an echo signal which is reflected to an object with a multiplex echo signal when the parking area is recognized using an ultrasonic sensor. CONSTITUTION: An apparatus(100) of recognizing a parking space comprises; a signal transmission unit(110) which transmits a signal using a sensor; an echo signal receiving unit(120); a multiplex echo signal generator(130) creating a multiplex echo signal from the echo signal based on a preset first critical value and a second critical value; and a parking space recognition unit(140) which recognizes the parking spaced based on a round trip time and a duration.
