Overview of Inertial Measurement Units (IMUs)

To record the six possible kinematic degrees of freedom

We are distributor for Europe

nexonar is a specialist for motion capturing and 3D coordinate measurement. The Japanese company LP Research is partner for inertial measurement units (inertial measurement unit - IMU). nexonar now offers IMUs for those interested in the European market. Through the close cooperation of both companies, complex individual solutions can be implemented in the area of 3D motion tracking for customers.

The advantage of the LP Research platform is that the fusion of complex mathematical sensor data is already included. This dramatically reduces development times and prevents failures in product development. Different setups can be simply configured and controlled to find the optimum conditions for each individual application as quickly as possible. An indispensable basis for a low-cost development of IMU applications.

The nexonar team supports your development team with optimal solutions for your requirements. We are happy to consult with you so that you quickly and effectively get ahead in the IMU development environment.

Sensor Calibration

Besides data acquisition, visualization and logging, LPMS- Control allows calibration of the LP motion sensor’s MEMS components. The application offers offset and misalignment calibration for the unit’s gyroscope and accelerometer, as well as magnetometer calibration functionality.

While accelerometer and gyroscope calibration is usually done at our factory before delivery to the customer, the calibration parameters of the magnetometer can vary strongly depending on the usage of the sensor.

Therefore the so-called hard- and soft iron calibration is an essential tool to adjust the sensor to work well in a specific environment. LPMS-Control offers a comfortable method to calibrate the magnetometer. Additionally to the pure calibra- tion, the application also visualizes the shape of the environment magnetic field and shows the impact of magnetic noise on the sensor performance.

LpSensor Library

The LpSensor library contains classes that allow a user to integrate LPMS devices into their own applications. We provide the library pre-compiled for different operating systems. The standard library is written in C++, but we also offer wrappers for Python, C# and C. MATLAB and LabView ports are under development. Should your application require a specific soft- ware integration please contact us.

The code snippet below shows the most simple method of connecting to the sensor and reading data. For deeper insight in the programming library and the full source code of LPMS-Control please have a look at our code repository.

Mobile Application
As part of the open motion analysis toolkit (OpenMAT) we offer support to monitor and log data from our wireless sensors using mobile devices. See below a screenshot of a sample program for Android. The application is well suitable for data logging tasks as is. Additionally we provide source code for users to modify the program to fit their specific requirements. An iOS version with similar functionality to the Android application is currently under development.

LPMS Control Software



All LP-RESEARCH sensor devices are delivered with a software package. The software package contains the LPMS-Control application for general control of the sensors and a program- ming library for users to implement their own applications communicating with the sensor. The LPMS-Control application allows users to control various aspects of an LPMS device. In particular the application has the following core functionality:

  • Lists all LPMS devices connected to the system
  • Connects to up to 256 sensors simultaneously. Multiple connection interfaces (Bluetooth, CAN bus etc.) can be used at the same time.
  • Adjusts all sensor parameters (sensor range etc.).
  • Sets orientation offsets.
  • Initiates accelerometer, gyroscope and magnetometer calibration.
  • Displays the acquired data in real-time either as line graphs or a 3D image.
  • Records data from the sensors to a CSV data file.
  • Plays back data from a previously recorded CSV file.
  • Uploads new firmware and in-application-programming software to the sensor.
