How to Calibrate MPU6050 sensor using MATLAB?
Show older comments
I need to know is there any command to calibrate my MPU6050 sensor? Because from one video on youtube the person used "readCalibrationstatus()" this command for his 9-axis BNO055 sensor. Also I want to know how to apply complimentary filter on the angular velocity matrix in below code:
Code:
clc
clear all
%Setting up Arduino and making object
ard = arduino
%Setting up IMU Sensor and making object
my_sens = mpu6050(ard)
%Capturing IMU Data
imu_read = read(my_sens) %Collecting data from IMU Sensor
imu_matrix = imu_read{:,:} %Converting data into matrix form
imu_mean = mean(imu_matrix) %Computes mean of 10 sample values for each column
%Tabulating mean data for one instance (@10 smaples)
imu_table = array2table(imu_mean, 'VariableNames', {'Acc_x','Acc_y','Acc_z','Gyro_x','Gyro_y','Gyro_z'})
%Printing Accelration Values
acc_x = imu_mean(:,1);
acc_y = imu_mean(:,2);
acc_z = imu_mean(:,3);
%Creating Accelration Matrix
accelration_matrix = [acc_x, acc_y, acc_z]
%Printing Angular Velocity Values
angvel_x_rad = imu_mean(:,4);
angvel_y_rad = imu_mean(:,5);
angvel_z_rad = imu_mean(:,6);
%Creating Angular Velocity Matrix
angvel_matrix = [angvel_x_rad, angvel_y_rad, angvel_z_rad]
Now i am stuck after this.Its just I collected raw data from the sensor and put them in matrix. Also I need calibration for my sensor. Please help.

Calibration for the BN appears to be by using hardware registers that invoke device hardware whose details are not documented. Unfortunately it is not a matter of just changing device addresses to select similar hardware; the calibration for the BN is built in to the hardware.

Haris, if you dont mind can you share how you calculate it?
