A visual method tor the detection of available parking slots

Visual sensors are widely used in automatic parking systems, so this paper proposes an algorithm for the visual detection of available parking slots. The proposed system consists of two stages: parking slot recognition and slot occupancy classification. The parking slot recognition stage generates parking slots using the corner features of parking slot markings. The slot occupancy classification stage verifies the availability of the parking slot using the features of detected slots. The experimental results demonstrate that the proposed method effectively detects available parking slots in AVM images.
