As an essential medical device, a bag infusion set is often used for intravenous infusion, and part of the set. Due to unavoidable defects in production process, quality detection bags critical ensure use In this paper, we adopt machine vision system inspect assembly lanyard dosing interface liquid conduct in-depth discussion research from image acquisition, defect strategy, algorithm two missing missing. The design acquisition auxiliary mechanism realized solve complex problem due irregular shape assembly; based on determining study contour extraction finally completed through comparison experiments extract precise piping area; finally, virtual straight line method proposed combined with ROI selected according position feature outer rectangle count number contours completed, goal achieved. pipeline rate paper reaches 100%, which can perfectly replace existing manual visual inspection reduce employment cost enterprises.
