Question 1

New features

Accepted Answer

- UI editor for the most important model configuration parameters: Edit the available default configurations in the UI and save the modified configurations easily as user configurations. The latter are then directly available in the configuration menu. - Added new configruation files for GEOCAL laser wavelengths 638nm and for the GEOCAL IR with 935nm. - Added option IMAGE_FIELD for the configuration entry RadiusFilterForDetectedPoints : Unit="GRID_ORDER" works as in version 1.5.0, that means the maximum radius (1.0) is defined as the relative distance of the detected grid point with biggest radial distance to the 0th order grid point. Unit="IMAGE_FIELD": the maximum radius (1.0) is defined as the relative distance from the corners of the image to the center of the image. - Import / export of detected grid points: The detected grid points of the GEOCAL image can be saved as CSV files. Such files can be imported as new detecion data for an analysis. - Field of View (FoV) calculation for alle distortion models: FoV in horizontal, vertical and diagonal direction. - Optional rre-calculation of the focal length: A more precise focal estimation can be run before the distortion parameter calculation. - New "HDR" algorithm for merging two images with different exposures - Logging functionality: Displays information, warnings and errors in the UI and saves it to a log file - New command line interface (CLI): Allows to use batch scripts for automated analysis of multiple images and/or configurations. - Implemented new Rational Function Distortion Model and the OpenCV Rational model - Undistort function: Choose a measurement result and load any image to undistort it. The resulting image can be saved to disk. This feature supports the Even-Brown and the Fisheye model. - New RMSE statistics with respect to region (radius restriction for field of view in the image plane) and to quantiles of the RMSE deviation. For example, a 98% quantile excludes 2% of the points with the greates deviation in RMSE. The statistics can be edited in the configuration files. - The units of the resulting distotion parameters can be calculated as physical units of the sensor size. The known pixel pitch can be entered in the configuration files in the entry NormalizeToSensorSize in units of µm. - Support of PGM file format - Abort button for running detection and analysis - Option for connecting detection and analysis procedure: in version 1.4 detection of grid. points and subsequent analysis were separated, now both can be combined into one workflow - New result overview in addition to the result table.

Question 2

Improvements

Accepted Answer

- General revision of the whole GUI - Speed up of detection and analysis

Question 3

Fixes

Accepted Answer

- Many minor fixes

Question 4

New

Accepted Answer

- Added configuration parameter for excluding detected grid points in relation to relative radius with origin in image center. - Added simple HDR Tool for merging image stacks with GEOCAL images with different camera exposure settings. - Added more parameters to configuration files, which allow for more accurate and stable estimation of focal length parameter

Question 5

Improved and Fixes

Accepted Answer

-Improved point detection -Some Fixes

Question 6

Added

Accepted Answer

- Added software version to window title. - Added defaultname to export dialogs. - The detected grid can now be displayed even when the detection failed

Question 7

Updated

Accepted Answer

- GEOCAL-API to 1.2.2. - XML configuration file to Version 4:

Question 8

Updated UI

Accepted Answer

- Added 2d color scatter plot - Added quiver plot - Added detected and reprojected points to image - Added control labels to detect and analyse buttons - Added detection histogram - Update IE color bar - Change position of "Show detected grid" button

Question 9

Updated XML configuration file to Version 3

Accepted Answer

- Added some comments - Added new Parameter "DetectionParameter"

Question 10

Bug fix

Accepted Answer

- calculation of alpha

Question 11

Updated File Dialog

Accepted Answer

File dialog saves its last path.

Question 12

Updated XML configuration file

Accepted Answer

- configuration file is now versioned. actual verion: 2 - Now it is possible to set a start value for optimization with new tag "UseAsStartValue" - Rename Tag "SetToInvariant" to "IsInvariant" - Parameter check: parameters has to be numbers. Otherwise the reading of the file is aborted.

Updated GEOCAL-API

Accepted Answer

- the software now uses the GEOCAL-API 1.0.1.

Question 14

Bug fixed

Accepted Answer

- Program no longer crashes when image has wrong number of channels.

Question 15

Renamed

Accepted Answer

- example_configuration.xml file to default_configuration.xml.

Question 16

Updated configuration file

Accepted Answer

- Now it is possible to choose between different distortion models.

Question 17
