Script for Matlab to calculate QE by Raw Bayer data, captured by Raspberry Pi script.

Status: Stable.

This project were made for my thesis into Optolab Lab at Enzo Ferrari University at Modena.

Program's tree:

• bayer_all.py : Raspberry Pi script for capture images with space bar.

  This Script must have intalled in a Rasp:

  • py-getch: https://goo.gl/jeLuDv
  • picamera: https://goo.gl/QFMRFa

On Rasp's console: python camera.py

• BayerRgb_to_RGB : folder with MatLab script.

  Open it on MatLab and follow the instruction on top.

Study step by step:

Raspberry setup:

1. Load the bayer_all.py on raspberry, you could use scp *folderName.zip* pi@IP: .

2. Put in front of raspberry camera the slit of monochromator.

3. Run the script and follow the istruction on monitor. Step by step, move the trigger on monochromator and take a pic with space bar.

4. The Rasp's script will save a folderName.zip file with your Raw Bayer data, called numberX.npy .

5. You could use scp pi@IP:*folderName.zip* . to grab the file from the raspberry to your Unix terminal destination pc ( linux or mac ) .

MatLab setup:

1. Open plot_mix.m in Matlab

2. Remember to set the number of captures, if you have more then one, keep in mind to start with NDF lower to NDF highter.
