Real time multiple two dimensional barcode reader

The proposed work describes a system that can be used to detect and decode multiple Two-Dimensional (2D) barcodes (i.e. Datamatrix). The proposed system is capable of detecting and decoding of barcodes covered by polyethylene foiling in moving images. The foiling causes reflection on the captured images and hence provides challenges to detection/decoding. Similarly the proposed system addresses the problem of poor lighting conditions. The main contribution is the design of an optical hardware setup that is integrated with machine vision algorithms to successfully address the reflection and illumination challenges. A recognition accuracy of approximately 98% is achieved.
