#camera-webservice

Summary:

Here is a Python webservice called webservice.py written for this event. Google won't help you with any information specifically about the script, but you will find lots of information about the libraries used in the script. Proceed in steps.

1 - Setup the Raspberry Pi and take a photo

1. Install required prerequisites:
   • OS Package dependencies (hint: use apt-get): python-pip fswebcam git
   • Python module dependencies (hint: use pip): flask flask-restful boto3 elasticsearch
   • On Windows: Additionally the Python module pillow and the CommandCam photo software placed in same directory as webservice.py
2. Take a photo with fswebcam or commandcam.exe, transfer this to your laptop (scp, and maybe winscp are your friends), and verify the camera focus is good. Repeat as necessary :-)

2- Setup the camera-webservice

1. Clone the repo from github (hint: use git)
2. Copy the camera-webserivce config.json.example to config.json
3. Update all parameters to meet your needs
4. For the camera_command parameter these might be helpful:
   • Example linux USB camera: fswebcam -r 1280x720 --jpeg 85 --no-banner -S 20
   • Example native raspberry camera module: raspistill -o
   • Example windows usb camera: CommandCam.exe /quiet /filename

3 - Run the Camera webservice
