| Abstract: | To devise a machine vision system based on virtual instruments which can be used in the field of apertures measurement of work pieces. The background-lighting was chose as lamp-house in this system. Nonlinear calibration and finding circle edge were introduced to measure the images acquired, To put forward and realize a method based on LabVIEW which can be used to initialize and optimize the central parameters automatically and with which the precision of repeating inspection can be ensured. It is proved by experiments that the apertures of work pieces can be measured quickly and the results are perfect. |
