Description

OpenMV IMU Expansion board can not only obtain acceleration, speed, magnetic field, more importantly, can directly obtain posture, including four yuan, Euler angle.

OpenMV IMU扩展板

The IMU shield board uses a BNO055,9-DOF sensor with a built-in attitude fusion algorithm that fuses the accelerometer, magnetometer, and gyroscope data into a stable three-axis direction.

OpenMV can obtain the following sensor data:

• Absolute direction (Euler angle, 100Hz) three-axis direction data
• Absolute Orientation (Quaterion, 100Hz) Four point quaternion output for more accurate data manipulation
• Angular Velocity Vector (100Hz) Three axis of ‘rotation speed’ in rad/s
• Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2
• Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)
• Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2
• Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2
• Temperature (1Hz) Ambient temperature in degrees celsius
