1. A parking area detecting method, comprising:
- generating a top view image by capturing images of surroundings of a vehicle;
detecting a first directional parking line from the top view image;
detecting at least one second directional parking line having a direction different from that of the first directional parking line from the top view image; and
detecting a parking area by combining the first directional parking line and the second directional parking line;
wherein the detecting of the parking area includes;
detecting a square area defined by connecting the first directional parking line and the at least one second directional parking line; and
determining the square area as the parking area,wherein a parking area previously detected exists, andwherein the method further comprises;
comparing the parking area currently detected with the parking area detected previously;
determining a proportion of an overlapping area between the parking area currently detected and the parking area previously detected; and
registering the parking area currently detected as a new parking area if the overlapping proportion is equal to or less than a pre-set proportion.

Abstract
A parking area detecting method includes generating a top view image by capturing images of surroundings of a vehicle, detecting a first directional parking line from the top view image, detecting a second directional parking line having a direction different from a direction of the first directional parking line from the top view image, and detecting a parking area by combining the first directional parking line and the second directional parking line.

6. A parking area detecting method, comprising:
-
generating a top view image by capturing images of surroundings of a vehicle; detecting a first directional parking line from the top view image; detecting a second directional parking line having a direction different from that of the first directional parking line from the top view image; and detecting a parking area by combining the first directional parking line and the second directional parking line, wherein the detecting of the second directional parking line includes; detecting edge pixels at a pre-set angle with respect to the first directional parking line among the edge pixels included in the top view image; measuring differences between a linear template and the edge pixels by positions of the first directional parking line by using the linear template; and determining positions of local minimum points of the differences, as positions of the second directional parking line, wherein a parking area previously detected exists, and wherein the method further comprises; comparing the parking area currently detected with the parking area detected previously; determining a proportion of an overlapping area between the parking area currently detected and the parking area previously detected; and registering the parking area currently detected as a new parking area if the overlapping proportion is equal to or less than a pre-set proportion. - View Dependent Claims (7)

8. A parking area detecting method, comprising:
-
generating a top view image by capturing images of surroundings of a vehicle; detecting a first directional parking line from the top view image; detecting a second directional parking line having a direction different from that of the first directional parking line from the top view image; detecting a parking area by combining the first directional parking line and the second directional parking line; calculating reliability of a parking area on the basis of a difference of the second directional parking line constituting the parking area; calculating occupancy of an interior of the parking area by using position information of an object around the vehicle obtained by an ultrasonic sensor; and determining a parking area on the basis of the reliability and occupancy, wherein a parking area previously detected exists, and wherein the method further comprises; comparing the parking area currently detected with the parking area detected previously; determining a proportion of an overlapping area between the parking area currently detected and the parking area previously detected; and registering the parking area currently detected as a new parking area if the overlapping proportion is equal to or less than a pre-set proportion.

9. A parking area detecting method, comprising:
-
generating a top view image by capturing images of surroundings of a vehicle; detecting a first directional parking line from the top view images; detecting a second directional parking line having a direction different from that of the first directional parking line from the top view image; detecting a an available parking area by combining the first directional parking line and the second directional parking line; when a parking area detected previously exists, predicting a current location according to a movement of the vehicle with respect to the a parking area detected previously; comparing the available parking area with the parking area detected previously and determining a proportion of an overlapping area between the available parking area and the parking area detected previously; and whenupon the overlapping area isproportion being equal to or less than a pre-set proportion, registering the available parking available area as a new parking area, and when upon the overlapping area exceeds proportion exceeding the pre-set proportion, selecting one of the available parking available area and the parking area detected previously. - View Dependent Claims (10)
