Abstract
Disclosed herein is a method for recognizing a parking space line marking for a vehicle, including: detecting, by a processor, a plurality of parking spaces from a portion of a parking space line marking in an image; calculating, by the processor, an overlap coefficient representing a degree of overlapping between the detected parking spaces; selecting, by the processor, a parking space having a largest brightness coefficient as a final parking space by determining overlap when the overlap coefficient has a predetermined magnitude and comparing the brightness degrees of the overlapped parking spaces.
Claims19
A method for recognizing a parking space line marking for a vehicle, comprising:
- detecting, by a processor, a plurality of parking spaces from a portion of a parking space line marking in an image;
- calculating, by the processor, an overlap coefficient representing a degree of overlap between the detected plurality of parking spaces;
- calculating, by the processor, a brightness coefficient of the detected plurality of parking spaces;
- and
- selecting, by the processor, one parking space from the detected plurality of parking spaces having a largest brightness coefficient as a final parking space by determining an overlap when the overlap coefficient includes a predetermined dimension and comparing brightness degrees of the overlapped parking spaces.
A controller for recognizing a parking space line marking for a vehicle, comprising:
- a memory;
- and
- a processor configured to:
- detect a plurality of parking spaces from a portion of a parking space line marking in an image;
- calculate an overlap coefficient representing a degree of overlap between the detected parking spaces;
- calculate a brightness coefficient of the detected parking spaces;
- and
- select a parking space from the detected parking spaces having a largest brightness coefficient as a final parking space by determining an overlap when the overlap coefficient includes a predetermined dimension and comparing brightness degrees of the overlapped parking spaces.
A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:
- program instructions that detect a plurality of parking spaces from a portion of a parking space line marking in an image;
- program instructions that calculate an overlap coefficient representing a degree of overlap between the detected parking spaces;
- program instructions calculate a brightness coefficient of the detected parking spaces;
- and
- program instructions select a parking space from the detected parking spaces having a largest brightness coefficient as a final parking space by determining an overlap when the overlap coefficient includes a predetermined dimension and comparing brightness degrees of the overlapped parking spaces.
