The visual code may be a Quick Response (QR) code that contains information useful to calibrating a variety of navigation-based sensors such as gyroscopes, e-compasses, and barometric pressure sensors. Embodiments describe methods for magnetometer calibration and computing sensor orientation relative to users' local frame of reference. The embodiments use an initial yaw estimate, accelerometer, and gyroscope measurements along with other readily available information (the earth's magnetic field intensity, inclination angle, and declination angle)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetormeter calibration for navigation assistance","description":"Visual codes are scanned to assist navigation.
