Comparative Study and Analysis of Human Knee Angle Measurement System

Human gait analysis is one of the most important tools to drive the actuator of the bionic leg, which is designed and acts on the command received from the gait system. In this article, we implemented the inertial measurement unit (IMU) and image processing system using Kinovea software to measure the human knee angle. A traditional tool called goniometer was used to measure the human knee angle. An updated new modified goniometer is introduced in this project to analyze the human gait system. IMU sensors are interfaced with Arduino, and the data was acquired and stored in the PC for the purpose of further analysis. The Kinovea is one the powerful sports analysis software, which was introduced here to measure the human knee angle measuring in different lightening condition. The comparative human knee angle measurement was studied, in that the acquired data was compared with each other system.
