Abstract
Disclosed are a parking space recognition method and apparatus. The inventive parking space recognition system includes: a vehicle edge extraction unit for extracting a vehicle edge of a counterpart vehicle positioned adjacent to a parking space by analyzing an image acquired by a camera; a vehicle position extraction unit for extracting a vehicle position of the counterpart vehicle by analyzing ultrasonic wave data acquired by an ultrasonic sensor; a vehicle edge position analysis unit for analyzing the vehicle edge position for the extracted vehicle edge by mapping the extracted vehicle edge and the extracted vehicle position; and a parking space recognition unit for recognizing the parking space by determining the position of the counterpart vehicle on the basis of the analyzed vehicle edge position. According to the present invention, a sensor convergence type parking space recognition technology using a camera and an ultrasonic sensor in such a manner that the disadvantages of the ultrasonic sensor and the camera can be compensated with each other.
