Development of global vision system for biological automatic micro-manipulation system

Abstract

An automatic micro manipulation system, which aims at various kinds of operations in the field of bio-engineering has been developed. Visual servo control is usually employed to improve the performance of the system. However, the great amount of computation that is required in image processing hinders the formation of a closed-loop control system with visual servo. In this paper, efforts are made to improve the performance of the vision system in two aspects: algorithm design and hardware implementation. Methods of correlation based pattern matching and morphological operation based image processing technique are used to implement the fast visual information abstraction, thus forming a real-time visual servo control system. The system performance and the result of an experiment on gene injection are given.
