Hybrid Parking Detection

摘要

The present invention combines the strengths of the background-subtraction and edge-detection algorithm for parking detection. Being computationally efficient, the background-subtraction algorithm is used whenever possible. On the other hand, being robust, the edge-detection algorithm is used at calibration points, or when the background-subtraction algorithm cannot reliably determine the parking state.

1. A hybrid parking-detection device, comprising:
an optical detector for capturing a image of a parking area, said parking area including a plurality of parking spaces; a memory for storing at least a background-subtraction algorithm and an edge-detection algorithm; a processor for detecting parked vehicles in said parking area, wherein said processor is configured to select said background-subtraction algorithm under a first condition and select said edge-detection algorithm under a second condition.
