People Counter for Events
Advanced AutonomyIntermediate Robotics plus perception pipelines, control loops, coordinate frames, and real-time behavior.
Before you start
- Complete Camera Module
- Understand object tracking, image coordinates, and basic data logging
- Use an instructor-approved person detector
Build a stationary camera project that estimates how many people cross a doorway or hallway boundary during a session.
Project Outcome
Display a live in, out, and total count with a timestamped session summary.
Camera Input
- Person detections and stable track identifiers
- A virtual crossing line in image or depth space
- Recent positions for each active track
Build Stages
- Draw and verify the crossing line.
- Detect people without counting them.
- Track each detection across frames.
- Count only when a track crosses from one side to the other.
- Add a cooldown or completed-track record to prevent duplicates.
- Save aggregate counts without storing identifying imagery.
First Prototype
Count crossings in one direction and display the current total.
What To Measure
- Missed crossings
- Duplicate counts
- Behavior when people overlap or reverse direction
- Count accuracy over a known test group
Extensions
- Add separate entry and exit totals.
- Show hourly counts on a local dashboard.
- Compare image-line and depth-line crossing logic.
- Add a reset control for a new session.
Safety And Privacy
Keep the robot stationary and position equipment so it does not block the walkway. Store aggregate counts by default; do not add face recognition or identifying records.
