picam

A server that allows a raspberry pi camera to be controlled with an HTTP API and an admin GUI. It can also be run as a docker container.

The server takes a picture every X seconds and also allows you to take a picture on demand and configure the options. You can currently only access one photo at a time.

API

take a picture = $ curl -X POST http://picam/photo

get the picture = $ curl http://picam/photo.jpg

get camera options = $ curl http://picam/camera

set camera options = $ curl -X PUT http://picam/camera -H "Content-Type: application/json" -d '{}'

note: you can optionally pass camera options when taking a picture, for example:

$ curl -X POST http://picam/photo -d '{}'

GUI

Go to http://picam/admin for the admin GUI that allows you to take a picture, view a picture, and change the camera options

Docker

$ docker build -t jritsema/rpi-picam:1.1.1 .
$ docker tag -f x jritsema/rpi-picam:latest
