Abstract

The spot centroid localization is one of the key problems in various fields of scientific research and engineering applications. This paper proposed a novel algorithm based on profile regularization of the detecting spots. The algorithm first roughly eliminates the background and random noise errors by an a priori statistically estimated threshold; then determines the profile edge of the spot region by using morphological filtering technique; last calculates the centroid position with a center of weight algorithm. The field experiments were performed to validate the presented algorithm. The experimental results have demonstrated the superiorities of the proposed centroid detection algorithm on precision, stability and repeatability. This study is of value in improving the precision of center location algorithms.
