Detailed Description

Factor to estimate rotation given magnetometer reading This version uses model measured bM = scale * bRn * direction + bias and assumes scale, direction, and the bias are given. Rotation is around negative Z axis, i.e. positive is yaw to right!

		const Point3 &	measured,
		double	scale,
		const Unit3 &	direction,
		const Point3 &	bias,
		const SharedNoiseModel &	model
	)

inline

Constructor of factor that estimates nav to body rotation bRn

Parameters

key	of the unknown rotation bRn in the factor graph
measured	magnetometer reading, a 3-vector
scale	by which a unit vector is scaled to yield a magnetometer reading
direction	of the local magnetic field, see e.g. http://www.ngdc.noaa.gov/geomag-web/#igrfwmm
bias	of the magnetometer, modeled as purely additive (after scaling)
model	of the additive Gaussian noise that is assumed
