Count People in a Queue from a Photo — Queue Length Counter

Queue length is the single most visible service metric a business has, and it is almost never actually measured — just apologised for. Upload a photo of the queue and get a headcount with every person marked for review.

  • Counts dense crowds as well as small groups
  • Built for retailers and service desks
  • Stop recounting because someone moved halfway through
  • Review every detected person directly on the marked result

Prepared settings

Starting point
One wide photo of the queue
Stand to the side and shoot along the line so every person is visible in profile; switchback queues count best from above.
Prepared workflow
Count people in a queue
People mode and automatic scene routing are already selected; there is no detector to find manually.
Reviewable output
A marked headcount and downloadable record
Detected people are marked so the total can be checked against the source instead of accepted as a black box.
Review rule
Review every marker before using or sharing the total
Occlusion, blur, and people at the frame edge can affect a count; correct any missed or duplicate marker first.

Best-fit uses

  • Queue-length records at known peak times
  • Before-and-after proof for a staffing change
  • Service-level evidence in tenant or landlord disputes

Frequently asked questions

How do I count people in a queue from a photo?
Upload one clear photo of the queue and the AI marks every person it detects, with the total shown on top. Stand to the side and shoot along the line so every person is visible in profile; switchback queues count best from above. Review the markers and adjust sensitivity before you rely on the number.
Does it work when the scene is packed?
Yes — dense scenes switch automatically to a crowd-density engine built for gatherings where people overlap, with a heatmap and dots showing where the estimate comes from. Occlusion still hides people, so treat busy-scene results as reviewed estimates and use a higher, wider vantage when you can.
How do I turn a queue count into a wait time?
Divide the counted queue by your service rate — 12 people waiting at 2 minutes per customer on 3 desks is roughly an 8-minute wait. Photograph the line at the same times daily and the counts become your service-level record.
Is the people counter free, and what happens to my photo?
Yes — count, review and download the marked-up result without creating an account, and the headcount itself is identical on every plan. Downloads are free without a watermark. No signup required. Photos are encrypted in transit, processed to produce the count, and removed under our Security policy.

Count

Included markersSliderRange: 0–1 · Default: 0
Starts at Show more so every returned people marker is visible; slide toward Only strongest to keep fewer relative top-ranked markers, and the headcount updates instantly.
Overlay stylePresets
Sets how counted people appear on the preview — dots, a density heatmap, both, or a clean image — so you can verify the headcount visually.Options: BothDotsHeatNone
Include people facing awayOn / Off
Counts people turned away, in profile, or whose face is hidden — not just visible faces — while never counting one person twice and never counting legs alone as a person. For genuinely dense crowds it escalates to a density estimate.
Max accuracy (slower)On / Off
Runs every counting engine on the photo and cross-checks their results for the most dependable headcount, taking a little longer to process.
Detection sensitivitySliderRange: 0–1 · Default: 0.5
Controls how eagerly people are marked, from Strict to Lenient — raise it if people in small groups are missed, lower it if things that are not people get counted.
