A Tool for Creating Calibrated Images

A synthetic imaging tool by which three-dimensional model descriptions given in OpenGL are converted into images, is described. Camera parameters are also extracted and attached to the images. Conversion of OpenGL matrices to calibration parameters and conversion of calibration parameters to OpenGL matrices are explained in detail. Radial distortion is also modeled, so that images become more realistic. The libraries, created in the scope of this work, are made publicly available over Internet under <www.cv.tu-berlin.de/~ulas/rarf>. In the lack of time or photographing equipment, the tools presented in this study would be vital for the researchers who want to test their surface modeling and calibration algorithms.
