Abstract

A computer-implemented technique can process overhead images of users in a line at a venue to obtain a user wait time for the line. The processing can include (a) identifying a user of the group of users that is second in the line to obtain a target user, (b) detecting when the target user becomes first in the line to obtain a start time, (c) after the target user becomes first in the line, detecting when the target user leaves the line to obtain an end time, (d) determining a period from the start time to the end time, and (e) calculating the user wait time by calculating a product of (i) the determined period and (ii) a quantity of the group of users in the line after the target user leaves the line. The calculated user wait time can then be output.

Claims

1. A system, comprising:

a camera attached to a surface in an area where a group of users congregate and configured to capture images of the group of users at a frame rate and/or a resolution based on a distance from the camera to the group of users, wherein higher frame rates and higher resolutions correspond to greater distances and lower frame rates and lower resolutions correspond to smaller distances; and

one or more processors configured to;

obtain the captured images;

apply a set of filters to the images to obtain filtered images, wherein each filter of the set of filters further distinguishes users from noise;

monitor movement of the group of users relative to the area using vector representations in a defined coordinate system;

determine a user density metric for the area based on the monitoring of the group of users relative to the area over a period; and

output an indicator of the determined user density metric for the area for storage, analysis, and/or display.

2. The system of claim 1, wherein the surface is overhead of the group of users in the area and the camera is configured to capture overhead images of the group of users in the area, and wherein the distance is a distance from the camera to a ground surface of the area.

3. The system of claim 2, wherein the camera has a curved fish-eye lens.

4. The system of claim 1, wherein the set of filters comprises a filter that defines boundaries in each of the captured images to exclude edges of the captured images.

5. The system of claim 1, wherein the surface is located towards an outer edge of the area and the camera is configured to capture at least partially side view images of the group of users in the area.

6. The system of claim 1, wherein the indicator of the determined user density metric for the area comprises at least one numerical value.

7. The system of claim 1, wherein the indicator of the determined user density metric for the area comprises at least one non-numerical visual indicator.

8. The system of claim 1, wherein the indicator of the determined user density metric for the area is an indicator of a percentage of the area that the group of users currently physically occupies.

9. The system of claim 1, wherein the indicator of the determined user density metric for the area is an indicator of a wait time for one or more lines in the area in which at least some of the group of users are waiting.

10. The system of claim 9, wherein the one or more processors are configured to calculate the wait time based on an average wait time for each user in the one or more lines over the period.

11. The system of claim 1, wherein the indicator of the determined user density metric for the area is an indicator of an average time that users remain in the area before leaving the area.

12. The system of claim 1, wherein the indicator of the determined user density metric for the area is an indicator of an average time that users remain in a portion of the area before moving to another portion of the area or leaving the area.

13. The system of claim 1, wherein the determined user density metric for the area is a relative user density metric relative to a separately determined user density metric for another group of users in another area.

14. The system of claim 1, wherein the determined user density metric for the area is output to a third-party analytics system.

15. The system of claim 1, wherein the determined user density metric for the area is output to a remote server for at least temporary storage.

16. The system of claim 1, wherein the determined user density metric for the area is output to a remote monitor for display.

17. The system of claim 1, wherein the determined relative density of the area is output to a personal mobile computing device of a remote user in response to a request.

18. The system of claim 1, wherein the area is an ingress or egress area, a viewing or seating area, a concessions area, a merchandise area, or a restroom area at an entertainment venue.

19. The system of claim 1, wherein the area is an ingress or egress area, a shopping area, a purchasing area, an elevator or escalator area, or a restroom area at a business or retail venue.

20. The system of claim 1, wherein the one or more processors are integrated into the camera or are part of a computing device that is distinct from the camera.
