Pose Detection for Exercise Correction

March 2024
FitTech Solutions
Duration:8 months

Overview

Developed posture correction and rep-counting solutions using OpenPifPaf, quantized for TensorRT mobile edge devices.

This pose detection system helps users maintain proper form during exercises, reducing injury risk and maximizing workout effectiveness.

Leveraging OpenPifPaf's powerful pose estimation capabilities, we created a solution that provides real-time feedback on posture and automatically counts repetitions.

The model was extensively quantized to run efficiently on TensorRT-enabled mobile devices, making professional-level exercise guidance accessible to everyday users.

Challenges & Solutions

Accuracy with Partial Visibility

Implemented a temporal consistency algorithm to maintain accurate pose estimation even when parts of the body are temporarily occluded.

Battery Consumption on Mobile

Optimized inference frequency and developed an adaptive processing pipeline that adjusts computation based on movement intensity.

Exercise Classification Variety

Created a comprehensive dataset of over 50 common exercises and trained a separate lightweight classifier for exercise identification.

Client Feedback
