This software package contains routines for calibrating Roger Tsai's perspective projection camera model. Routines are provided for two levels of calibration. The second level is an extension of Tsai's algorithm in which the full 11 parameter model is numerically optimized.
Full optimization is slower but provides the most accurate calibration.
This software also contains routines for using the camera model and for gauging the model's accuracy. Click here for a description of the model. A detailed list of the changes in this release can be obtained by clicking here .
