Patent ID: 6880758

Claim:
A system for identifying an object having a bar code symbology, the system comprising: a measurement and input unit for measuring a height and a length of the object and inputting the measured values into the system; an object image and search region image storage unit for storing an image of the object and images of at least two sub blocks divided from the image of the object and searching a region from the image of the object at certain intervals; a search region setting unit for setting a size of the sub blocks; a region of interest having a possibility of containing the bar code symbology (ROI) generation unit for checking the sub blocks to only examine a surface of the object and the possibility of contaning the bar code symbology, setting a weight on every sub block, generating a characteristic value of the sub blocks and setting the ROI; a bar code symbology identification unit for vertically searching a bar code region from the ROI based on the weight and the characteristic value of the sub blocks, searching a section corresponding to reference information on a predetermined symbology based on a central line of the bar code region and generating a bar code edge region; an information interpretation unit for interpreting object information corresponding to the bar code edge region; and a result process and storage unit for processing and storing the interpreted object information based on data of pre-stored database if the interpreted object information exists in the pre-stored database and, if otherwise, notifying the search region setting unit of no existence of the object information.
