Preface
The following page describes the Eyesis4Pi camera software and post-processing procedures.
WebGUI (recording)
Eyesis4Pi GUI (PHP+JavaScript+HTML) should be installed on the laptop.
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
- Distortion correction
- Vignetting correction
- Color correction
- Denoising
- Sharpening
