Constructor & Destructor Documentation

◆ RollingShutterCameraDetectorMap()

Isis::RollingShutterCameraDetectorMap::RollingShutterCameraDetectorMap ( Camera * parent,
std::vector< double > times,
std::vector< double > sampleCoeffs,
std::vector< double > lineCoeffs )

Constructs a RollingShutterCameraDetectorMap.

Parameters
timesA std::vector of normalized readout times
coeffsA std::vector of the coefficients of the polynomial that fit the jitter. The coefficients are from highest degree to lowest degree.
parentThe parent camera that uses the detector map.

◆ ~RollingShutterCameraDetectorMap()

Isis::RollingShutterCameraDetectorMap::~RollingShutterCameraDetectorMap ( )
virtual

Destructor.

Member Function Documentation

◆ AdjustedStartingLine()

double Isis::CameraDetectorMap::AdjustedStartingLine ( ) const
inherited

Return the starting detector line adjusted for summation.

Returns
(double) The starting line

References Isis::CameraDetectorMap::p_sl.

◆ AdjustedStartingSample()

double Isis::CameraDetectorMap::AdjustedStartingSample ( ) const
inherited

Return the starting detector sample adjusted for summation.

Returns
(double) The starting sample

References Isis::CameraDetectorMap::p_ss.

◆ applyJitter()

std::pair< double, double > Isis::RollingShutterCameraDetectorMap::applyJitter ( const double sample,
const double line )

Iteratively finds a solution to "apply" jitter to an image coordinate.

Each iteration adds jitter to the original image coordinate until it finds an image coordinate that maps back to to the original image coordinate when jitter is removed. This is similar to how we handle applying radial distortion.

Note: If the jitter varies significantly (>1 pixel difference) then it is possible for there to be multiple solutions to the inverse problem and it is impossible to know which one to choose.

Parameters
sampleImage sample to apply jitter to.
lineImage line to apply jitter to.
Returns
std::pair<double,double> Returns the image coordinate with jitter applied to it.

◆ exposureDuration()

double Isis::CameraDetectorMap::exposureDuration ( const double sample,
const double line,
const int band ) const
virtualinherited

This virtual method is for returning the exposure duration of a given pixel.

For framing cameras, exposure duration is not available so it throws an error.

Parameters
sampleThe sample of the desired pixel.
lineThe line of the desired pixel.
bandThe band of the desired pixel.
Returns
double The exposure duration for the desired pixel in seconds.
Exceptions
IException::Programmer"Exposure duration is only available for LineScan, VariableLineScan, and PushFrame Cameras."

Reimplemented in Isis::LineScanCameraDetectorMap, Isis::PushFrameCameraDetectorMap, Isis::VariableLineScanCameraDetectorMap, and Isis::NirsDetectorMap.

◆ removeJitter()

std::pair< double, double > Isis::RollingShutterCameraDetectorMap::removeJitter ( const double sample,

Remove the distortion from the image (parent) coordinates.

This is a helper function for the SetParent method.

Parameters
sampleInput (parent) image sample coordinate.
lineInput (parent) image line coordinate.
Returns
std::pair<double,double> Returns a pair of doubles corresponding to the de-jittered sample and line. This is in image coordinates.
