Abstract:

Checker Pattern detection in the presence of miscellaneous background objects is a challenging task in computer vision systems. In practical applications, the direct detection of corner points fails due to the illumination variation in the lighting system. A computationally efficient checker pattern detection method using morphological operations and contour tree validation is proposed. The proposed method is tolerant to illumination, rotation and scaling variation. Comparative analysis with corner detection demonstrates the viability of the proposed algorithm as a valuable tool for automatic camera calibration and 3D measurements.
