Abstract
With the development of science and technology，especially information technology, image science technology has become an indispensable and powerful tool for scientific research. Using machine vision software to achieve the statistics of objects number has broad application prospects in modern industry automation, medicine, biology and many other fields. Among them, Labview Vision Assistant is an important tool in machine vision fields, which is the most widely and rapidly growing, most powerful graphics software integrated development environment. To realize these procedures that getting the statistics of the number of triodes, separating the triode base pin and the hose cap through image smoothing, threshold segmentation, hole-filling, swelling, corrosion is all by using modules of Lab view Vision Assistant Calculation. Experimental results indicated that to gather statistics to the triodes is simple and convenient with the use of machine vision software, also can improve working efficiency greatly and have good application value on the project.
