Procedures done at the post-processing stage
- Applying pixel mapping information
- Aberration correction
- Distortion correction
- Vignetting correction
- Color correction
- Denoising
- Sharpening
Requirements
- Linux OS (Kubuntu preferably).
- ImageJ and Elphel plugins.
- Calibration data (come with camera)
- default-config.corr-xml (comes with 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.
- Restore button -> browse for default_config.corr-xml (restores parameters for Configure correction)
- Configure correction button - make sure that the following paths are set correctly (if not - 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.
