Gait analysis is a method of gathering quantitative information to assist in determining the cause of abnormal gait for the purpose of making treatment decisions in veterinary medicine. Recent technology has offered the wearable wireless sensor of an inertial measurement unit (IMU) for determining gait parameters. This study proposed the use of a triaxial IMU, comprising an accelerometer, a gyroscope, and a magnetometer, for detecting three-dimensional limb segment motion ( axis) during the gait cycle in Asian elephants. A new algorithm was developed to estimate the kinematic parameter that represents each limb segment of the forelimbs and hindlimbs while walking at a comfortable speed. For future use, this study aimed to create a new prototype of the IMU with a configuration that is tailored to the elephant and apply machine learning in an effort to achieve greater precision.
步态分析是一种收集定量信息的方法，用于协助确定异常步态的原因，以便在兽医学中做出治疗决策。最近的技术提供了用于确定步态参数的惯性测量单元（IMU）可穿戴无线传感器。本研究提出使用包含加速度计、陀螺仪和磁力计的三轴IMU，来检测亚洲象在步态周期中的三维肢体节段运动（轴）。开发了一种新算法，以估计亚洲象以舒适速度行走时代表前肢和后肢各肢体节段的运动学参数。为了未来的应用，本研究旨在创建一种针对大象量身定制配置的IMU新原型，并应用机器学习以实现更高的精度。
