From 9dccfa01fc3a9067e51f9d76aafb74f6478c9276 Mon Sep 17 00:00:00 2001 From: Tyler Wilson Date: Mon, 4 Mar 2019 11:24:29 -0700 Subject: [PATCH] Added I/F calibration step to hyb2onccal (#3132) * Added AlphaCube group to outputlabel in the event the image is cropped. * Fix libtiff dependency (#636) (#644) * Upgrade libtiff to 4.0.10 (#636) * Switch libtiff to 4.0.9 or higher to remove geotiff conflict * Moved ISIS3 conda-build recipe from ISIS3_deps repository (#650) * Fixed warning in Pixel unit tests * Made a tweak to the dimensions of the alpha cube for cropped images to give it the correct dimensions. * Changed the transform function so it could process an array of doubles instead of an array of ints. * Smear correction was being incorrectly applied to onboard smear corrected images and screwing things up. Fixed it. * Added gtest capability to hyb2onc2isis * Removing build numbers from external libraries (#660) * Moved ISIS3 conda-build recipe from ISIS3_deps repository * Un-pinned non-astro build numbers * Removing build numbers from external libraries in the environment and meta.yeml files * Final merging * Added pixel type attribute to the output image of program shadow. Fixes #5187 (#659) * Removed bolding of some text to decrease distraction. * Fixed some typos. * Reworded documentation. * Added section for Environment and PreferemcesSetup in the Getting Started Section. (#663) * Updated .gitmodules to use https rather than ssh (#673) * Added build type release to conda recipe (#676) * Modified isis/tests/CMakeLists.txt as well as hyb2onc2isis to fix unresolved symbol errors (CMakeLists.txt) and to fix some bugs in hyb2onc2isis involved with turning it into a callable function. * Added w1 test to hyb2onc2isisTests.cpp * Modified hyb2onccal to be a callable function. * Updates README with Discourse (#690) * Updates README with Discourse * Update README.md * Update README.md * Changed the Pvl label output for Pvl hyb2onc2isis(QString fitsFileName, QString outputCubeFileName, CubeAttributeOutput att, QString target) * Added Newton-Rapheson method to Hyb2OncCalUtils.h to solve the linearity equation. * Final push of hayabusa2 changes made to the ingestion/calibration applications. * Added I/F calibration step. Cleaned up code base and worked on the documentation. The documentation will need to be corrected before this is merged into dev. * Fixed a missing tag in hyb2onccal.xml --- .../apps/hyb2onc2isis/hyb2onc2isis.cpp | 13 +- .../apps/hyb2onccal/Hyb2OncCalUtils.h | 228 +++++++----------- .../hayabusa2/apps/hyb2onccal/hyb2onccal.cpp | 62 ++--- .../hayabusa2/apps/hyb2onccal/hyb2onccal.xml | 186 ++------------ isis/tests/hyb2onc2isisTests.cpp | 32 ++- 5 files changed, 171 insertions(+), 350 deletions(-) diff --git a/isis/src/hayabusa2/apps/hyb2onc2isis/hyb2onc2isis.cpp b/isis/src/hayabusa2/apps/hyb2onc2isis/hyb2onc2isis.cpp index 987e6ae55d..222d27ae4c 100644 --- a/isis/src/hayabusa2/apps/hyb2onc2isis/hyb2onc2isis.cpp +++ b/isis/src/hayabusa2/apps/hyb2onc2isis/hyb2onc2isis.cpp @@ -53,6 +53,7 @@ void hyb2onc2isis(UserInterface &ui) { Pvl hyb2onc2isis(QString fitsFileName, QString outputCubeFileName, CubeAttributeOutput att, QString target) { + Pvl finalPvl; ProcessImportFits importFits; importFits.setFitsFile(FileName(fitsFileName)); importFits.setProcessFileStructure(0); @@ -138,7 +139,7 @@ Pvl hyb2onc2isis(QString fitsFileName, QString outputCubeFileName, CubeAttribute // Translate the Instrument group - FileName transFile(transDir + "hyb2oncInstrument1.trn"); + FileName transFile(transDir + "hyb2oncInstrument.trn"); if (updatedKeywords) { transFile = transDir+"hyb2oncInstrumentUpdated.trn"; @@ -255,14 +256,16 @@ Pvl hyb2onc2isis(QString fitsFileName, QString outputCubeFileName, CubeAttribute // Convert the image data importFits.Progress()->SetText("Importing Hayabusa2 image"); - Pvl finalLabel = *(outputCube->label() ); + importFits.StartProcess(); importFits.Finalize(); - return finalLabel; - + + return outputLabel; + } -} + + diff --git a/isis/src/hayabusa2/apps/hyb2onccal/Hyb2OncCalUtils.h b/isis/src/hayabusa2/apps/hyb2onccal/Hyb2OncCalUtils.h index 967cf07920..dfefe3e3fe 100644 --- a/isis/src/hayabusa2/apps/hyb2onccal/Hyb2OncCalUtils.h +++ b/isis/src/hayabusa2/apps/hyb2onccal/Hyb2OncCalUtils.h @@ -120,14 +120,12 @@ static double g_compfactor(1.0); // Default if OutputMode = LOSS-LESS; 16.0 for static QString g_iofCorrection("IOF"); //!< Is I/F correction to be applied? // I/F variables -static double g_solarDist(1.0); /**< Distance from the Sun to the target body -(used to calculate g_iof) */ -static double g_iof(1.0); //!< I/F conversion value + static double g_iofScale(1.0); static double g_solarFlux(1.0); //!< The solar flux (used to calculate g_iof). -// TODO: we do not have this conversion factor for Hayabusa 2 ONC. -static double g_v_standard(1.0); -// static double g_v_standard(3.42E-3);//!< Base conversion for all filters (Tbl. 9) +static double g_sensitivity(1.0); +static double g_effectiveBandwidth(1.0); + namespace Isis { @@ -186,12 +184,74 @@ bool newton_rapheson(double Iobs,double x0, double g[3],double &result, double e /** -* @brief Apply radiometric correction to each line of an AMICA image. + * @brief linearFun: The linear correction function (used by the newton_rapheson method) + * @author 2019-02-12 Tyler Wilson + * @param Iobs: The observed intensity + * @param x: The ideal intensity. + * @param g: The vector of empirically derived coefficients for the third-order polynomial + * modelling the linear correction (for DN values < 3400 DN) + * @return The value of the function at the point x. + */ +double linearFun(double Iobs,double x, double g[3]) { + return Iobs - g[0]*x -g[1]*pow(x,2.0) -g[2]*pow(x,3.0); + +} + +/** + * @brief dFun: The first-order derivative of linearFun + * @author 2019-02-12 Tyler Wilson + * @param x: The ideal intensity. + * @param g: The vector of empirically derived coefficients for the third-order polynomial + * modelling the linear correction (for DN values < 3400 DN) + * @return + */ +double dFun(double x, double g[3]) { + return -g[0] - 2*g[1]*x -3*g[2]*pow(x,2.0); + +} + +/** + * @brief newton_rapheson + * @author 2019-02-12 Tyler Wilson + * @param Iobs: The observed DN intensity + * @param x0: The starting value for the Newton-Rapheson method + * @param g: A vector of the coefficients for the linearity function.

Notes

-
    -
  1. - Smear correction is not currently provided, as we do not have the readout time - (charge-transfer period) for the instrument. -
    2. -
  2. - Similarly, since no radiance values could be found for the instrument filters, the output - cannot be correctly converted to radiance or I/F. -
