At 221e, our expertise lies in developing Edge AI solutions that blend reliability, precision, and efficiency. One of our holy grails is our proprietary MPE (Motion Processing Engine) sensor fusion software, built specifically to enhance the performance of 9-Axis IMUs. Whether you’re developing products for VR motion tracking, athlete performance monitoring, or industrial use, our tools are designed to provide accurate, real-time results without the usual problems like drift or magnetic interference.
Let’s examine how a 9-axis IMU works, its benefits, and why sensor fusion and Edge AI matter more than ever in motion tracking.
Understanding the 9-Axis IMU
A 9-axis IMU (Inertial Measurement Unit) is a motion-tracking sensor that combines three accelerometers, three gyroscopes, and three magnetometers. Together, they track movements along multiple axes (pitch, roll, and yaw) providing a full 3D picture of motion.
When paired with the right software, a 9-axis IMU can provide highly detailed orientation data in real time. This is especially useful for applications like VR motion tracking, where even minor inaccuracies can break immersion or cause motion sickness.
Miniature IMU: Big Capabilities in Small Packages
Modern motion tracking solutions need to be compact and efficient. That’s where the miniature IMU shines. These small-sized sensors offer powerful tracking without taking up much space, making them ideal for:
- Wearables for athlete performance monitoring
- Motion capture in VR headsets
- Robotics and automation applications
- Healthcare monitoring systems
Their size doesn’t compromise performance. In fact, with the integration of sensor fusion software like our MPE, these compact powerhouses can deliver accurate, stable, and dependable data.
Why Sensor Fusion Matters in Motion Tracking
Motion tracking isn’t always reliable. Raw data from accelerometers, gyroscopes, and magnetometers can be noisy or subject to environmental factors like magnetic distortion. That’s why sensor fusion plays a vital role.
Our MPE software processes input from all axes using advanced filtering algorithms, specifically, an Extended Kalman filter. This technique combines data from multiple sensors to give a more accurate and consistent result, even under difficult conditions.
Whether you’re developing VR sensors or autonomous machines, sensor fusion minimizes the errors that come from individual sensors. The results are a noticeable improvement in stability and reduced drift over time.
Common Challenges Solved by 9-Axis IMUs
Even the best motion sensors face real-world challenges. Without the proper support, you may encounter:
- Drift over time, causing the orientation to become inaccurate
- Magnetic disturbances, especially in urban environments
- Incorrect orientation, affecting performance and user experience
With MPE on your side, these issues become manageable. Our software intelligently filters out noise and inconsistencies, delivering results that closely match real-world motion, after all, it was developed for real-world scenarios.
This makes it an ideal solution for:
- Sports tech and athlete performance monitoring
- Industrial motion control systems
- Mobile robots and drones
- Virtual and augmented reality systems using VR motion tracking
Precision You Can Count On
Accuracy isn’t just a feature, instead it’s the crux of any motion-sensing device. Whether your application involves VR sensors, wearable technology, or vehicle navigation systems, your IMU must offer dependable results every time.
Our MPE software ensures that the 9-axis IMU delivers:
- Real-time 3D orientation: access to immediate and accurate spatial tracking so that your applications perform fluidly.
- Minimal drift and noise: advanced filtering that provides accuracy with near-zero drift.
- Stable performance during motion or at rest: Our proprietary sensor fusion performs better than other competitors in conditions of low, medium and high motion dynamics.
- Reduced magnetic interference: intelligent calibration for environments with fluctuating electromagnetic fields.
With such a high level of accuracy, your product shouldn’t just function, it should perform exceptionally in the real world, even in challenging environments.
Real-World Applications of the 9-Axis IMU
Let’s take a closer look at some practical uses of the 9-axis IMU across different industries.
1. VR Motion Tracking
For virtual reality, orientation and position tracking are key to creating an immersive experience. A 9-axis IMU, when paired with well-built sensor fusion software, gives you the responsiveness and realism needed for natural user interactions.
2. Athlete Performance Monitoring
Real-time data obtained from wearables helps coaches and athletes understand motion mechanics, prevent injury, and improve form. Our MPE software adds reliability to the feedback, making the data not just abundant but meaningful.
3. Autonomous Systems
In drones, robots, and self-driving vehicles, up-to-date orientation and direction data is essential. Our software helps these machines operate safely and reliably by providing accurate spatial awareness in real time.
4. Medical Applications
Rehabilitation devices and motion-sensitive monitoring systems are using IMUs to track patient movement. The compact design of miniature IMUs, combined with accurate sensor fusion, makes them ideal for wearable medical devices. An example is demonstrated in this case study where our miniature IMUs were embedded with sensor fusion algorithms as part of a system designed to help in neurorehabilitation.
