Calibrator

Calibrate your projector-camera system on a single click.

• Generates both projector and camera intrinsic and extrinsic matrices
• Spacial scan supports 720p and 1080p projectors
• Spacial scan supports Canon DSLR
• Live view with Canon DSLR
• Saves spacial scan image
• Supports Windows and OS X

Usage

Parameters

• Corners: Checkerboard pattern size (e.g. this pattern has corners of 9x6)
• Size: Physical dimension of checkerboard grid or circle spacing, usually in millimeter
• Threshold: Projector view binary image threshold
• b: Percentage of light emitted by a turned-off projector pixel
• m:

Dependencies

• Qt (4.8.6)
• OpenCV (2.4.11)
• EDSDK (2.15)

Build

OS X

1. Install Qt and OpenCV from homebrew.

   $ brew install qt opencv

2. Move the EDSDK folder to lib/EDSDK, replace lib/EDSDK/Framekwork/EDSDK.framework to be the 64 bit version.

3. Build with make or Qt Creator IDE.

   $ cd calibrator/build
   $ qmake
   $ make

Windows

1. Install Qt libraries 4.8.6 for Visual Studio 2010 and latest OpenCV binary. Remember to add C:\Qt\4.8.6\bin and C:\opencv\build\x86\vc10\bin to environment variable PATH.

2. Build with nmake or Qt Creator IDE.

   $ cd calibrator/build
   $ qmake
   $ nmake release
