Realization of Ellipsoid Fitting Calibration for Three-axis Magnetic Sensor Based on STM32 Embedded System
field error calibration compensation method of three-axis magnetic sensor in STM32 embedded systems.Firstly,we analyzed the source of the error and established the error model.Then,we got the error coefficient by computing the parameter of the ellipsoid.At last,we realized this algorithm in STM32 embedded systems.The experiment results showed that the magnetic sensor can be calibrated and compensated in the embedded directly after this system realized.Thus,it is not necessary to collect data and process data in MATLAB.And,the accuracy compensated by the embedded system has not been reduced more than 3°,meets general commercial requirements.
