Method and apparatus for recognizing parking lot

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.

Description

technical field [0001] The present invention relates to a method and system for identifying a parking lot, and more particularly, a technique for identifying a parking space using a camera and an ultrasonic sensor. Background technique [0002] Due to the development of the automobile industry, the number of automobiles has grown substantially, and automobile technology has also been fully developed. Especially, due to the development of electronic technology, there has been a lot of research on smart car technology. Among them, the driver assistance system (DAS) has made significant improvements with the advancement of technology, and has been applied in smart cars. [0003] Among driver assistance systems, parking assistance systems are also widely studied in the field of smart cars, and have been practically applied in cars. Such a parking assist system mainly assists the driver in parking. [0004] Such a parking assistance system can be divided into a parking space r...

AI Technical Summary

Problems solved by technology

[0005] In the traditional parking space recognition method, there is usually a problem with the ultrasonic parking space recognition method, that is, due to the limitation of the transmission distance and resolution of the ultrasonic wave, the counterpart vehicle (counterpart vehicle) adjacent to the parking space where the vehicle wants to park The edges of can't be extracted precisely, so the parking space can't be identified precisely

There is a problem with the conventional parking space recognition method using a camera that the parking space cannot be accurately recognized because the position of the opposing vehicle cannot be accurately recognized by determining the distance to the opposing vehicle

[0006] That is to say, in order to identify the parking space, no matter whether the ultrasonic sensor or the camera is used, there is a problem in the traditional parking space recognition method, that is, due to the respective shortcomings of the ultrasonic sensor and the camera, the parking space cannot be accurately identified.
