What is IMU drift?

What is IMU drift?

The IMU orientation is usually obtained by integrating the angular velocity measured with the gyroscope [6,11,13,14,15,16,17]. This allows for immediate detection of orientation changes but leads to a drift of the estimated orientation over time, e.g., due to gyroscope bias [18].

How do you stop IMU drifting?

Filtering the gyroscope output within an IMU using a low-pass or Kalman filter is also a widely used method to cancel a portion of the drift error.

What is integration drift?

It is a well-known fact that the use of numerical integration of acceleration/angular rate information from inertial sensors (accelerometers/gyroscopes) to obtain position/orientation information inherently causes position/orientation errors to grow with time, which is commonly known as “integration drift”.

What three components are in an IMU?

An IMU is a specific type of sensor that measures angular rate, force and sometimes magnetic field. IMUs are composed of a 3-axis accelerometer and a 3-axis gyroscope, which would be considered a 6-axis IMU. They can also include an additional 3-axis magnetometer, which would be considered a 9-axis IMU.

What is the IMU responsible for?

An Inertial Measurement Unit (IMU) is a device that can measure and report specific gravity and angular rate of an object to which it is attached.

Does drift integrate with Salesforce?

Drift’s native integration with Salesforce is the most extensive for any messaging platform. We know that if you have a Sales team and have reached a certain scale, you’re likely using Salesforce.
