Procedures

  • Applying pixel mapping information
  • Aberration correction
  • Distortion correction
  • Vignetting correction
  • Color correction
  • Denoising
  • Sharpening

Requirements

  • Linux OS (Kubuntu preferably).
  • ImageJ and Elphel plugins (most of the post-processing).
  • Hugin tools - enblend (for simple stitching).
  • ImageMagick - convert (for converting).
  • PHP
  • Get calibration kernels for the current Eyesis4Pi (come on a HDD with a camera).
  • Get default-config.corr-xml (come on a HDD with a camera).
  • Download footage from the camera.

Instructions

  • Launch ImageJ from Eclipse

  • Go to Plugins -> ImageJ-Elphel -> Eyesis Correction
Note: if plugin needs to be recompiled - Plugins -> Compile & Run. Find and select Eyesis_Correction.java.

Eyesis corrections plugin interface
  • Restore button > browse for default-config.corr-xml (should be located on the drive with calibration data, restores parameters for Configure correction)
  • Configure correction button - make sure that the following paths are set correctly (if not - edit or mark the checkboxes - a dialog for each path will pop up):

Source files directory                - directory with the footage images
Sensor calibration directory          - [YOUR-PATH]/calibration/sensors
Aberration kernels (sharp) directory  - [YOUR-PATH]/calibration/aberration_kernels/sharp
Aberration kernels (smooth) directory - [YOUR-PATH]/calibration/aberration_kernels/smooth
Equirectangular maps directory(may be empty) - [YOUR-PATH]/calibration/equirectangular_maps (it should be created automatically if the w/r rights of [YOUR-PATH]/calibration allow)

Source file suffix - .jp4 if jp4 files are processed
Sensor files prefix - the format is <prefix>NN.calib-tiff - <prefix> is blank if the files are just NN.calib-tiff. For XXX-NN.calib-tiff the prefix would be XXX-
Sensor files suffix - default is .calib-tiff
Kernel files (sharp)/(smooth) prefix - same rule as for the sensor files
Kernel files (sharp)/(smooth) suffix - default is .kernel-tiff
Equirectangular maps prefix - same rule as for the sensor files
Equirectangular maps suffix - default is .eqr-tiff

  • Configure warping (Skip if the files already exist) -> rebuild map files - this will create maps in [YOUR-PATH]/calibration/equirectangular_maps. Will take ~5-10 minutes.
  • Select source files -> select all the footage files to be processed.
  • Process files to start the processing. Depending on the PC power can take ~20 minutes for a panorama of (24+2) images.
  • The last 2 rows of the UI are experimental and not related to Eyesis4Pi. No need to use.
  • After processing is done there is only the blending step. It can be launched manually or from the WebGUI:
    • WebGUI
    • Manual blending: the following script scans directory for *.tiffs from ImageJ and uses enblend (to stitch into 16-bit tiffs) and converts them into jpegs, in terminal:

php stitch.php [source_directory] [destination_directory]
- no slashes in the end of the paths
