METHOD AND APPARATUS FOR LOCALIZATION OF ONE-DIMENSIONAL BARCODES

摘要

The proposed method and apparatus localizes one or more one-dimensional barcodes present in a digital image. The method uses a line segment detection algorithm detecting line segments in the digital image. Further, the line segments detected are clustered together as belonging to probable barcodes based on the orientation and distance between each line segment. The line segments in a cluster are joined by growing a ray in the direction perpendicular to the line segments. Further, the various clusters are subjected to connected component analysis in order to identify valid barcodes. Further, the location of the barcode and the bounding box details of the barcode are returned. Based on the location and bounding box details, the barcode may be read using barcode readers.
