Locating the Center of Circular Targets Based on Mathematical Morphology

SUN Yingchao,LI Zhenhai (School of Geodesy and Geomatics,Wuhan University,Wuhan 430079,China)  
The paper useed morphological operators for image pre-processing,then detected the edge with an improved robust morphology arithmetic,and locateed the center of Retro-Reflective Targets by least-square fitting,Test demonstrates that this arithmetic can eliminate the noise effectively and locate the center accurately.
