1- per panorama
WebGUI (recording)
- PHP+JavaScript+HTML.
- Installed on the laptop or PC used for recording.
Output
- Images in a JP4 format(a RAW format with a better quality than *.jpeg).
- Binary log with the IMU,GPS and Internal Timestamp records.
Post-Processing
A. WebGUI part (PHP + JavaScript + HTML)
- Copying images before processing.
- Extracting GPS coordinates from images.
- Stitching (after ImageJ).
- Formatting/resizing the results.
B. ImageJ part (Java)
- Applying pixel mapping information
- Aberration correction
- Distortion correction
- Vignetting correction
- Color correction
- Denoising
- Sharpening
