Open-Source IMU Signal Processing Tools
54 open-source tools for inertial measurement (IMU) and accelerometer data, most often in Python, R and Java. Each listing shows its licence, commercial use and last commit.
What open-source tools process IMU and accelerometer data from wearables?
An inertial measurement unit (IMU) combines accelerometers, often with gyroscopes and magnetometers, to record movement. Wearables use it for activity, sleep and gait.
