Description
Contribution generators seems wrong for the partial derivative part respect to rotation angles
and scale factor
equation used:
(X -Xbar) = ech* R * (x - xbar) +T"
with T" = T + ech * R * xbar -Xbar
Using notation of chaba in
TLSHelmertParametersCG::processHTObservations(TChabaLSCalcDataSet* ds,
LSPointPairIter pair)
X1 = ech * R *x2 + T + ech * R * xbar -Xbar
Partial derivative respect to rotation angle and scale are using this equation:
X1 = ech* R * x2 +T
Comments
Comment by Marie Barbier [ 15/Jan/16 ]
Rewritte contribution and equation with barycentre and T (not T").
Two tests have been added in TestChabaProject to check calculation results. Some other tests
with the interface will be done to compare chaba with SA.
