| Abstract: | Most Chinese enterprises are using artificial visual detection to inspect defects of one-off injectors. According to the status quo, an on-line inspection system of syringe needle defects based on virtual instrument is developS.The system controls stepping motor through c ] FP-PWM-520 module which is produced by NI Company. IMAQ VISION software package is used to perform image processing, including filtering, image enhancement, automatic threshold, morphologic processing, location, template matching and etc. The tests indicates that the system can meet the demands of on-line defect detection of all kinds of syringe needles. |
