Automated video based ingress/egress sensor reset for truck stop occupancy detection
First Claim
1. A method for parking occupancy detection comprising:
- collecting video of a parking facility with a video camera;
counting an occupancy of said parking facility using at least one sensor to establish a sensor occupancy count;
classifying each of a plurality of parking spots as occupied or vacant with a classifier according to a classification threshold in order to establish a video occupancy count;
determining a difference between said sensor occupancy count and said video occupancy count; and
setting said sensor occupancy count according to said difference between said sensor occupancy count and said video occupancy count.

Abstract
A method and system for parking occupancy detection comprises collecting video of the parking facility with a video capturing device, counting an occupancy of a parking facility using at least one sensor to establish a sensor occupancy count, classifying each of a plurality of parking spots as occupied or vacant with a classifier according to the classification threshold in order to establish a video occupancy count, determining a difference between the sensor occupancy count and the video occupancy count, and setting the sensor occupancy count to equal the video occupancy count if the difference between the sensor occupancy count and the video occupancy count exceeds a difference threshold.

17. A method for parking occupancy detection comprising:
-
collecting video of a parking facility with a video camera; counting an occupancy of said parking facility using at least one sensor to establish a sensor occupancy count; assigning a classification threshold wherein said classification threshold is dependent on said sensor occupancy count; establishing an ROC curve for said parking facility; determining a current sensor occupancy count; selecting a threshold value on said ROC curve associated with said current sensor occupancy count; classifying each of a plurality of parking spots as occupied or vacant with a classifier according to said classification threshold in order to establish a video occupancy count; determining a difference between said sensor occupancy count and said video occupancy count; and setting said sensor occupancy count according to said difference between said sensor occupancy count and said video occupancy count. - View Dependent Claims (18, 19, 20)
