Short answer accelerometer gyroscope sensor fusion:
Accelerometer and gyroscope sensors are commonly used to provide data for motion tracking. Sensor fusion is the process of combining data from multiple sensors to increase accuracy and reduce drift. A common method of sensor fusion involves using a complementary filter, where the accelerometer provides short-term stability and the gyroscope provides long-term stability.
Accelerometer Gyroscope Sensor Fusion: A Step-by-Step Guide
As technology progresses and we become more dependent on our electronic devices, the demand for smarter and more capable sensors has only increased. From smartphones to drones, high-end robotics systems to vehicles, engineers are always looking for ways to improve accuracy, reliability and efficiency in sensor data collection.
One of the most fundamental aspects of many sensing applications is the ability to measure motion accurately. This requires a combination of accelerometer and gyroscope sensors, both of which are common in modern electronics.
However, because both these sensors have drawbacks when used standalone, it’s becoming increasingly popular for engineers to combine them through sensor fusion algorithms – creating a highly accurate motion sensor system.
Accelerometers: Measuring linear acceleration
Accelerometers are commonly used to measure linear acceleration as they detect forces acting upon an object in terms of movement along an axis. They’re a fairly simple device composed of a mass attached to a spring; when the object (with the spring/mass) moves or accelerates along an axis (e.g., left/right), then its relative position changes from that of equilibrium resting position leading to a return force proportional to distance.
This leads to outputting precise information about how much “g”’s (units of gravitational force) are being exerted on the device at any given time.
Gyroscopes: Measuring angular velocity
On the other hand, gyroscopes measure angular velocity by registering rotational movements such as twisting/wobbling around one or more axes. This measurement is immensely important in numerous applications – camera positioning for example – where motion blur can be avoided by processing acceleration measured via pre-integrated orientation values using gyroscopes’ data readings into rotational pitch/yaw rates.
So while accelerometers give us information about linear displacement/movement (also useful!), gyroscopes provide insight into rotational acceleration – together providing invaluable sensor fusion knowledge!
The challenge with individual sensors
Although each accelerometer/gyroscope offers unique benefits for measuring movement on its own merit, there are certain drawbacks.
When using only an accelerometer – its measurement becomes less reliable when the device is moving quickly or in a jerky, sudden fashion.
Alternatively, gyroscopes help offer accurate data for angles/positions being oriented – but its readings tend to drift due to imprecise readings or even surface finishes at times providing slightly contradictory feedbacks leading to inconsistency in output data quality when measured more than short periods of time (without the proper calibration regimen).
However when these two sensors are combined through sensor fusion algorithms it can result in a much more precise and effective solution – sometimes referred to as an IMU (inertial measurement units). Combining sensor data harnesses the benefits from each individual sensor allowing engineers to gain the full insight into movement with reduced error rates and ultimately more efficient application solutions.
Sensor Fusion: A game-changer
Developing Sensor Fusion algorithms has become all the rage among electronic engineers and manufacturers lately. Although the task may seem daunting at first glance, creating these algorithms doesn’t have to be as complicated as you might assume. Complex software often does several
