Method and system for automated sequencing of vehicles in side-by-side drive-thru configurations via appearance-based classification
First Claim
1. A computer-implemented method of automated sequencing of vehicles merging from multiple lanes into a single lane, the method comprising:
- a) an image-capturing device capturing video of a merge-point area associated with multiple lanes of traffic merging;
b) detecting in the video a vehicle as it traverses the merge-point area;
c) classifying the detected vehicle associated with traversing the merge-point area as coming from one of the merging lanes;
d) aggregating vehicle classifications performed in step c) to generate a merge sequence of detected vehicles;
wherein the multiple lanes of traffic merging correspond to a side-by-side drive-thru, and the side-by-side drive-thru includes an inner drive-thru lane and an outer drive-thru lane;
wherein a detected vehicle is tracked until the detected vehicle is outside the merge-point area; and
wherein the merge-point area is associated with a fast-food drive-thru.

13. A system for updating an event sequence, the system comprising an automatic sequencing device including a memory and a processor in communication with the processor configured to:
-
receive a number of individual order requests from the two order points, each order request being received when a vehicle is located in the one of the two order points; acquire video data of a lane merge point area from at least one image source, the merge point area associated with the convergence of two vehicle queue lanes from two respective order points to a single queue lane; process one of frames and at least one region of interest (ROI) in frames of the video data to detect a vehicle including at least a portion of the vehicle in the lane merge point area; track a movement of each detected vehicle through the lane merge point area over a subsequent series of frames until the detected vehicle is outside the lane merge point area; in response to the detected and tracked vehicle associated with the lane merge point area, classify one or more video frames as including a vehicle corning from an outer lane associated with order point A or a vehicle corning from an inner lane associated with order point B; update a sequence of the orders to match the determined sequence of vehicles in the single queue lane; and wherein the order points and lane merge point area is associated with a fast-food drive-thru. - View Dependent Claims (14, 15, 16, 17)
