用单个传感器和1D CNN实现马匹跛行早期精准检测

Convolutional neural network for early detection of lameness and irregularity in horses using an IMU sensor

  • 仅用一个惯性传感器+一维卷积网络,实现步态分类
  • 实测90%会话准确率,且零误报,适合现场使用
  • 低成本、非侵入式,适合兽医和马术日常筛查

跛行与步态异常是影响马匹健康、表现及经济价值的重要问题。传统观察法依赖主观判断,易漏诊轻微或早期症状。现有基于AI的方法多需多个传感器、测力台或视频系统,成本高且不适用于野外。本研究提出一种基于单个惯性测量单元(IMU)和一维卷积神经网络(1D CNN)的步态级分类系统,专注于检测马匹慢步时的跛行。系统在真实场景中测试,达到90%的会话级准确率,且无假阳性,展现出良好的实用性。该方法大幅降低硬件复杂度与成本,同时保持高分类性能,具备可扩展性。通过实现早期诊断,有助于防止轻度步态异常恶化,为提升马匹福利与运动表现提供有效工具。

原文摘要 · Abstract (English)

Lameness and gait irregularities are significant concerns in equine health management, affecting performance, welfare, and economic value. Traditional observational methods rely on subjective expert assessments, which can lead to inconsistencies in detecting subtle or early-stage lameness. While AI-based approaches have emerged, many require multiple sensors, force plates, or video systems, making them costly and impractical for field deployment. In this applied research study, we present a stride-level classification system that utilizes a single inertial measurement unit (IMU) and a one-dimensional convolutional neural network (1D CNN) to objectively differentiate between sound and lame horses, with a primary focus on the trot gait. The proposed system was tested under real-world conditions, achieving a 90% session-level accuracy with no false positives, demonstrating its robustness for practical applications. By employing a single, non-intrusive, and readily available sensor, our approach significantly reduces the complexity and cost of hardware requirements while maintaining high classification performance. These results highlight the potential of our CNN-based method as a field-tested, scalable solution for automated lameness detection. By enabling early diagnosis, this system offers a valuable tool for preventing minor gait irregularities from developing into severe conditions, ultimately contributing to improved equine welfare and performance in veterinary and equestrian practice.
