Real-time pullup counter in Rust. Uses a webcam and MoveNet pose estimation via tract to track shoulder and wrist keypoints, detect pullup reps with a state machine, and display a live count in the terminal.

How it works

1. Captures frames from your webcam (src/camera.rs)
2. Square-crops and resizes to 192x192, runs MoveNet on-device, and reads the shoulder and wrist keypoints out (src/movenet.rs)
3. Feeds each pose to a counter that flips Down to Up when the shoulders reach the wrists and back when they drop away, with a gap between the two so a wobble at either end never counts twice. Frames under a confidence floor are ignored (src/domain.rs)

The counter, the milestone messages and the crop bounds are plain functions with no camera or model behind them, and cargo test covers them. The thresholds are Thresholds::default() in src/domain.rs.

Setup

Prerequisites

• Rust toolchain (rustup)
• USB webcam

Get the model

mkdir -p models
cd models
wget https://qaihub-public-assets.s3.us-west-2.amazonaws.com/qai-hub-models/models/movenet/releases/v0.46.0/movenet-onnx-float.zip
unzip movenet-onnx-float.zip
cd ..

Run

cargo run --release

Stand back far enough that the camera can see your full upper body for best results. The terminal clears and displays the current rep count as you go.
