Realtime Football Curve Shot Posture Assessment Using Markerless Pose Estimation
The Real-Time Football Curve Shot Posture Assessment System is an AI-enabled sports analytics innovation developed to evaluate a player’s body posture during a football curve shot using multi-view video analysis and markerless pose estimation. The system is designed to support coaches, players, trainers, and sports researchers by providing an objective, explainable, and technology-driven method for posture assessment without requiring wearable sensors or expensive motion-capture equipment.The system captures the player’s kicking action from multiple camera angles, such as front, side, and rear views. These video streams are synchronized using an audio-based clap signal, allowing the system to analyze the same moment of action from different perspectives. The key event in the shot, the exact foot-ball contact frame, is identified by tracking the ball movement and the position of the player’s ankle.Once the contact frame is detected, the system applies markerless pose estimation to extract important body keypoints, including the shoulder, hip, knee, ankle, and foot. These keypoints are then used to calculate biomechanical posture parameters such as knee angle, trunk angle, and ankle angle. The calculated posture values are compared with predefined assessment ranges to generate rule-based feedback and an overall posture score.This innovation aims to make sports performance analysis more accessible, practical, and interpretable. It can help players understand their body alignment, balance, joint positioning, and technique during a curve shot. For coaches, the system provides a visual and data-supported method to identify posture errors and guide performance improvement.The technology represents a step toward low-cost, AI-based sports biomechanics solutions that can be used in training environments, academic research, sports coaching, and performance evaluation. By combining computer vision, artificial intelligence, and biomechanical analysis, the system demonstrates how modern digital tools can contribute to smarter and more scientific sports training.Key FeaturesMulti-view football shot video analysisAudio-based video synchronizationMarkerless pose estimation without wearable sensorsAutomatic foot-ball contact frame detectionKnee, trunk, and ankle angle calculationRule-based posture evaluationVisual feedback dashboard and posture scoringPractical application in sports training and biomechanics researchPotential ApplicationsFootball coaching and player trainingSports biomechanics researchAI-based performance assessmentInjury-risk awareness and posture correctionAcademic research and product-based innovationDevelopment of low-cost sports analytics toolsDeveloped under the innovation and research ecosystem of Amity Innovation and Design Centre (AIDC), Amity University Uttar Pradesh, this system reflects AIDC’s focus on transforming interdisciplinary research ideas into practical, product-oriented solutions.
