A rails application for remote capturing of pictures using GPhoto.
This application runs on any Linux machine, windows not tried yet, and was intended to run on a Beagleboard for use in a KAP setup (kite aerial photograpy).
If the installation seems a bit difficult, I plan to make available a disk image for the beagleboard that can be put on a memory card and run directly on a Beagleboard.
KAPture offera a web interface to the camera. The intenden use is to have th camera and a small linux computer (beagleboard) on a kite. The linux computer has a usb WLAN adapter configured with an adhoc network. On the ground, using a standard phone, you can connect to the adhoc network and capture images using buttons on a web page. Currently KAPture has the following functionality:
Capture an image
Capture many images automatically, continuously updating previews
Download previews and fullsize images
Automatic conversion of RAW images to JPEG for browsing
Automatic scaling of images to save bandwidth
Delete all images on camera
Delete all images on linux computer
Change camera settings such as image format (RAW/JPEG/compression), aperture etc. This is still a bit sketchy but works well for many settings. Many times the availability of a setting depends on which mode the camera dial is in.
Browse images captured during the session
You will need to install the following commands
dcraw (executable in standard folder /usr/bin)
cjpeg (executable in standard folder /usr/bin)
Also, the following gems
Install any other gems as they are reported missing ;-)
Two gems must be installed from github:
cd ~ sudo apt-get install libgphoto2-2-dev git clone git://github.com/tallakt/gphoto4ruby.git cd gphoto4ruby git fetch origin eos_40D_bugs:eos_40D_bugs git checkout -b eos_40D_bugs sudo rake install cd ~ sudo apt-get install libfreeimage-dev libfreeimage3 git clone git://github.com/tdd/image_science.git cd image_science sudo rake install_gem
Clone the project from GitHub
cd ~ git clone git://github.com/tallakt/kapture.git cd kapture
To generate the production database run the following commands from the
RAILS_ENV=production rake db:create RAILS_ENV=production rake db:migrate
Install the daemon services for thin and kaptured. The kaptured daemon will handle communication with the camera
It will now start with the machine, to start it now type
sudo /etc/init.d/kaptured sudo /etc/init.d/kaptured start sudo /etc/init.d/thin sudo /etc/init.d/thin start
At this stage, if everything went well, point yout browser to your machine name or ip address and plug in your camera to the USB port.
Running in development mode
Running in development mode is simple.
cd ~/kapture rake db:create rake db:migrate thin start
In a separate window type
cd ~/kapture script/runner lib/kaptured/kaptured.rb run
Log files and pid files should go in the log folder.
