- Applying pixel mapping information
- Aberration correction
- Distortion correction
- Vignetting correction
- Color correction
- Linux OS (Kubuntu preferably).
- Elphel ImageJ plugins.
- Locate calibration kernels for the current camera.
- Locate default-config.corr-xml.
- Launch ImageJ from Eclipse
- Go to Plugins -> ImageJ-Elphel -> Eyesis Correction
- 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-007 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
Also the following check boxes need to be checked:
De-mosaic Sharpen Denoise Convert colors Warp results to equiretangular Use projection to a common plane instead of the equirectangular
- 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 - all files should be named as *_1.jp4 (example: test_1.jp4, something was hard coded, we will fix later)
- Process files to start the processing. Depending on the PC power it can take ~1 minute per image.
