Virtual instruments can well fulfill the requirement of real time and precision whose combination possesses an outstanding practicability. Machine Vision System which is based on the virtual instruments is necessary and feasible; at the same time, it reduces the hardware device costs. Whats more, Machine Vision System is featured with high precision, high automation and non-contact. This paper introduces the common development platform of virtual instruments LabVIEW and its visual software module IMAQ Vision (Image Acquisition System Vision). Based on that, developing the Target Image Acquisition System Based on the logical structure of image measurement and analysis system, the Target Image Acquisition System is an important part of machine vision. Then this paper discusses the preprocessing procedure after the acquisition of image, as well as the technology and methods of image segmentation, which is the base for the design methods of Machine System and Target.Image Acquisition System in this paper.And with the Modular programming ideas, I finally accomplish the design of image measurement and analysis syste
