#ESPrtk

Uses artificial intelligence (AI) algorithms to eliminate noise and automatically find the correct rotation matrix for the sphere for magnetometer sensor calibration applications.

ESPrtk's calibration quality is very high.
The result was astonishing, with 99.99% eliminated noise. The algorithm works very well, even when only 1/4 surface point data exist in input data. Distortion and eccentricity due to hard-iron and soft-iron are completely removed.
The algorithm was developed exclusively by the ESPrtk development team and is already available on ESPrtk 3.9.8, so please update your ESP32 firmware.

-It has been tested many times with different data inputs (a lot of noise, missing spherical data) and both solved them perfectly. . Test results (.txt) in the video here: https://esprtk.files.wordpress.com/20...
