Abstract

Systems and associated methods are disclosed to reduce wait time experienced by customers during order fulfillment and pick-up. The system utilizes cameras and automatic license plate recognition (ALPR) to quickly identify vehicles associated with customer accounts and pending pick-up orders upon arrival. Proximity detectors provide an additional layer of vehicle detection. A concierge tool provides manual inputs from a user relating to vehicle or customer status. The system provides for synthesis and fusion of these diverse input types to accurately detect and identify arriving and departing customers.

Claims

1. A method of identifying a vehicle in a parking bay, the method comprising:

detecting, using a proximity sensor, a presence of a first vehicle within the parking bay;

communicating proximity data from the proximity sensor to a processing device, the processing device communicatively coupled to the proximity sensor;

determining, by the processing device, that the first vehicle is present within the parking bay;

detecting, using a camera communicatively coupled to the processing device, a first license plate of the first vehicle within the parking bay;

determining, by the processing device, a first candidate license plate identification of the first license plate;

determining, by the processing device, whether the first candidate license plate identification matches a stored license plate identification;

determining, by the processing device, whether the first candidate license plate identification corresponds to a pending pick-up order;

automatically checking in the first vehicle, by the processing device, for pick-up of the pending pick-up order when the first candidate license plate identification matches the stored license plate identification and when the first candidate license plate identification corresponds to the pending pick-up order;

receiving, by the processing device, from a concierge tool communicatively coupled to the processing device, a manual input indicating that the pick-up order is completed, the concierge tool comprising an electronic device;

setting, by the processing device, a status of the first vehicle as a departing vehicle in response to receiving from the concierge tool the manual input that the pick-up order is completed; and

after receiving the manual input indicating that the pick-up order is completed;

detecting a second time, using the camera, the first license plate of the first vehicle;

determining a second time, by the processing device, the first candidate license plate identification of the first license plate;

determining, by the processing device, that the status of the first vehicle is a departing vehicle; and

determining, by the processing device, to ignore the first candidate license plate identification.

2. The method of claim 1, further comprising:

prompting, by the concierge tool, to manually check in the first vehicle for pick-up of the pending pick-up order when the first candidate license plate identification does not match the stored license plate identification or when the first candidate license plate identification does not correspond to a pending pick-up order.

3. The method of claim 1, further comprising:

after receiving the manual input indicating that the pick-up order is completed, detecting, using the camera, a second license plate of a second vehicle within the parking bay;

determining, by the processing device, a second candidate license plate identification of the second license plate;

determining, by the processing device, that the second candidate license plate identification is different from the first candidate license plate identification; and

determining, by the processing device, that the second vehicle is an arriving customer.

4. The method of claim 1, further comprising:

after automatically checking in the first vehicle, receiving, by the processing device from the proximity sensor, an indication that the parking bay is unoccupied; and

determining, by the processing device, that the indication that the parking bay is unoccupied represents a customer departure event.

5. A method of identifying a vehicle in a parking bay, the method comprising:

receiving, by customer identification circuitry, from automatic license plate recognition (ALPR) circuitry coupled to a camera, at least a first license plate identification of a first vehicle in a parking bay, the camera capturing images of the parking bay;

categorizing, by the customer identification circuitry, the first vehicle as an arriving customer;

receiving, from a concierge tool comprising an electronic device communicatively coupled to the customer identification circuitry, a manual input indicating that a pick-up order corresponding to the first vehicle is completed;

after receiving the manual input that the pick-up order is completed;

receiving a second time, by the customer identification circuitry from the ALPR circuitry, the first license plate identification of the first vehicle in the parking bay;

categorizing, by the customer identification circuitry, the first vehicle as a departing customer; and

determining, by the customer identification circuitry, to ignore the first license plate identification in response to categorizing the first vehicle as a departing customer.

6. The method of claim 5, further comprising:

determining, by the customer identification circuitry, that the first license plate identification matches a stored license plate identification;

determining, by the customer identification circuitry, that the stored license plate identification corresponds to the pending pick-up order; and

automatically checking in the first vehicle, by the customer identification circuitry, for the pending pick-up order in response to determining that the stored license plate identification corresponds to the pending pick-up order.

7. The method of claim 5, further comprising:

determining, by the customer identification circuitry, that the first license plate identification does not match a stored license plate identification; and

prompting, by the concierge tool, to manually check in the first vehicle for the pending pick-up order via input to the concierge tool.

8. The method of claim 6, further comprising:

generating a first license plate hash value corresponding to the first license plate identification, wherein the stored license plate identification comprises a stored license plate hash value; and

determining that the first license plate hash value matches the stored license plate hash value.

9. The method of claim 5, further comprising:

generating a first license plate hash value corresponding to the first license plate identification;

determining that the first license plate hash value does not match a stored license plate hash value; and

storing the first license plate hash value as associated with a user account for the pick-up order.

10. The method of claim 5, further comprising:

receiving, by the customer identification circuitry from proximity sensor interface circuitry coupled to a proximity sensor configured to detect a presence of a vehicle in the parking bay, an indication that the parking bay is occupied by the first vehicle;

after receiving the manual input that the pick-up order is completed;

receiving, by the customer identification circuitry from the proximity sensor interface circuitry, an indication that the parking bay is unoccupied; and

determining, by the customer identification circuitry, that the indication that the parking bay is unoccupied represents a customer departure event.

11. The method of claim 5, further comprising:

after receiving the manual indication that the pick-up order is completed;

receiving, by the customer identification circuitry from proximity sensor interface circuitry coupled to a proximity sensor configured to detect a presence of a vehicle in the parking bay, an indication that the parking bay is occupied by a second vehicle received without a corresponding license plate identification from the ALPR circuitry for the second vehicle; and
