Magnetometer calibration python
Magnetic Calibration with Jupyter Jupyter Notebooks are a powerful cross-platform method for analyzing data using Python You can definitely use Jupyter to plot, analyze and calibrate your sensor data. This method is the most powerful because you can do plotting and calculations. WebThe same locus of magnetometer measurements represents the primary information available to the calibration algorithms to determine the hard- and soft-iron calibration V and W-1. Under arbitrary rotation of the smartphone by its owner, the magnetometer readings lie on a surface which can be derived from Equation 5 to be: Eqn. 11
