Member Function Documentation

degreesOfFreedom()

virtual ossim_uint32 ossimOptimizableProjection::degreesOfFreedom ( ) const

pure virtual

degreesOfFreedom() number of degrees of freedom (eg: 8 for bilinear, 6 for affine, 2 for translation) especially useful when not inheriting from AdjustableParameterInterface

Implemented in ossimSensorModel, ossimRpcProjection, ossimBilinearProjection, and ossimPolynomProjection.

needsInitialState()

bool ossimOptimizableProjection::needsInitialState ( ) const

virtual

needsInitialState()

Returns

This implementation returns false. Sub classes should true if the projection needs to be initialized to be optimized, eg: sensor models.

Reimplemented in ossimSensorModel.

Definition at line 33 of file ossimOptimizableProjection.cpp.

{
   return false;
}

operator=()

ossimOptimizableProjection & ossimOptimizableProjection::operator= ( const ossimOptimizableProjection &  source )

   // nothing to do (copy) in base.
   // if (this != & source)
   // {
   // }
   return *this;
}

optimizeFit()

virtual double ossimOptimizableProjection::optimizeFit ( const ossimTieGptSet &  tieSet, double *  targetVariance = 0  )

pure virtual

optimizeFit() adjusts projection to GLOBALLY fit best to ALL tie points (no outlier rejection) can select an optional threshold for accuracy

RETURNS : resulting image error variance of fitted model, or negative value for error

IMPORTANT : the unit for *targetVariance and the returned value is : meters^2 when useForward() is true OR pixel^2 if useForward() is false

Implemented in ossimSensorModel, ossimRpcProjection, ossimBilinearProjection, and ossimPolynomProjection.

setupOptimizer()

bool ossimOptimizableProjection::setupOptimizer ( const ossimString &  setup )

virtual

setupFromString() Derived classes should implement as needed. Initialize parameters needed for optimizeFit and degreesOfFreedom

Returns

This implementation does nothing and returns false.

Reimplemented in ossimRpcModel, ossimLandSatModel, ossimRpcProjection, ossimplugins::ossimFormosatModel, ossimSpot5Model, ossimApplanixEcefModel, ossimBilinearProjection, ossimSpectraboticsRedEdgeModel, ossimPolynomProjection, and ossimApplanixUtmModel.

Definition at line 27 of file ossimOptimizableProjection.cpp.

{
   return false;
}

useForward()

virtual bool ossimOptimizableProjection::useForward ( ) const

pure virtual

useForward() return true when it's better (more accurate / fast) to use forward (from ground to image) than inverse(from image to ground)

Implemented in ossimFcsiModel, ossimRpcModel, ossimplugins::ossimGeometricSarSensorModel, ossimSarModel, ossimRpcProjection, ossimLandSatModel, ossimAdjMapModel, ossimSonomaSensor, ossimplugins::ossimTileMapModel, ossimCoarseGridModel, ossimplugins::ossimFormosatModel, ossimSpot5Model, ossimRS1SarModel, ossimSkyBoxLearSensor, ossimApplanixEcefModel, ossimBilinearProjection, ossimIpodSensor, ossimSpectraboticsRedEdgeModel, ossimNitfMapModel, ossimRsmModel, ossimPolynomProjection, ossimApplanixUtmModel, ossimPpjFrameSensor, and ossimAlphaSensor.
