A Java application, that turns a webcam into a VisiCut compatible network camera with marker detection and perspective correction. Uses OpenCV through JavaCV

0. download JavaCV: On Linux, simply run ./lib/fetch-javacv.sh on the command line. On Windows, read the instructions in that file (Download and unpack ZIP).
1. Make sure you have apache-ant, java jdk >=6 and openCv installed (see below for OS-specific instructions)
2. run "ant" on the command line
3. run java -jar dist/VisiCam.jar on the Command Line or double click in finder/explorer

If you use it on ARM, you need to replace the javacv.jar in the dist/lib folder with the javacv.jar from the lib/javacv-pi folder. It works on ArchLinux (opencv can be installed through pacman). But is VERY SLOW. Any help is appreciated.

• Download and install Microsoft Visual C++ 2010 Redistributable Package (x86) http://www.microsoft.com/download/en/details.aspx?id=5555 or Microsoft Visual C++ 2010 Redistributable Package (x64) http://www.microsoft.com/download/en/details.aspx?id=14632

• Download OpenCV from http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.4.3/OpenCV-2.4.3.exe/download

• Add either the build/vc10/bin folder to PATH or copy all the dlls to the VisiCam folder

Install the required dependencies with: sudo apt-get install openjdk-8-jdk ant libopencv2.4

Read the Dockerfile for a more up-to-date list of all commands.

1. Place 4 Markers (Circles within circles) at the corners of you laser-bed
2. Place a webcam over the laser-cutter, so that it's image contains all the markers
3. Connect the webcam to a PC running VisiCam
4. Go to you webbrowser and enter the VisiCam URL (is printed on the Command Line after starting)
5. Click on "Get image from your webcam" to check if the camera is working and the markers are visible
6. Click on "Show Configuration". Here you can specify the resolutions and more important:
7. For each Marker-Position (top-left...) select a rectangle on the image, where VisiCam should search the marker
8. Save the configuration
9. In VisiCut go to Preferences->Manage Lasercutters->Edit and enter the CameraURL, which is the VisiCam URL with /image at the end. If you have the latest version, you can just click "search" and all VisiCam instances in your Network should appear.
