摘　　要：在气压式微喷系统的基础上,使用相应的机器视觉算法,基于LabVIEW开发平台及IMAQ Vision视觉工具包搭建视觉检测系统。该系统能通过BCG调节、二值化及形态学功能,最终实现对微小液滴高速移动的检测与运动分析。通过这样的液滴视觉监测系统,操作人员能预估实验过程中产生的液滴体积,进而更加有效地指导气微量液体的分配作业。Based on the pneumatic micro-jet system,the corresponding machine vision algorithm is used to build a vision inspection system based on the LabVIEW development platform and IMAQ Vision vision toolkit.The system can finally realize the detection and motion analysis of the high-speed movement of small droplets through BCG adjustment,binarization and morphological functions.Through such a droplet visual monitoring system,the operator can estimate the droplet volume generated during the experiment,and then guide the distribution of gas and trace liquids more effectively.
