A Novel Auto-focusing Method Applied to Micro Manipulation System
Abstract
The MEMS (Microelectromechanical Systems) technology is a new interesting research direction which aims to manufacture and assembly of micro-systems. The research of micro assembly robot has significances of academy and commerce. In the paper the theory and related key technologies of micro-assembly robot based on computer microscope vision feedback were investigated. To enlarge the manipulation area, a novel method of microscope focusing automatically was studied. The focusing process was carried out in cursory step and accurate one. The coarse focusing was based on the image gray histogram while the accurate one compared the width of image edges. Theory analysis and experiments showed that this algorithm enlarged the microscope focusing depth, with the advantages of simplicity and good real time performance.
