<p>A method and an apparatus for recognizing a parking area are disclosed. The parking area recognizing apparatus includes: a signal transmitter transmitting a signal using a sensor; an echo signal receiver receiving an echo signal for the signal; a multiple signal generator generating a multiple echo signal using the echo signal based on first and second preset thresholds; and a parking area recognizer recognizing a parking area by calculating a round trip time and a duration time for the multiple echo signal and selecting an available echo signal based on at least one of the round trip time and the duration time. Accordingly, a precision in recognition of a parking area is enhanced by reducing a measurement error by processing an echo signal received after it is reflected on an object with a multiple echo signal in recognition of the parking area using a sensor such as an ultrasonic sensor or a radar sensor.</p> |
