Image Based Faults Inspection of Cigarette Packets on LabVIEW Platform

This paper presents faults inspection scheme on cigarette packet on LabVIEW platform. The objectives of the proposed work are: (i) to count the number of cigarettes in an open packet, (ii) to check defect in the barcode, and (iii) to check defects on the label of the packet. A smart camera (from NI, India) is used to capture images from the required parts of the cigarette packets. These images are processed using various image processing techniques to achieve the above objectives. The proposed scheme is subjected to off-line testing on 300 sets of images of cigarette packets. The results obtained are found to be acceptable with an accuracy of 98.33% and hence the objectives of the present work are fulfilled. The accuracy of fault detection scheme can be improved by proper lighting arrangement.
