Abstract
According to one embodiment, a code recognition device includes a reader, a processor for region detection, for first extraction, and for second extraction. The reader photographs a code image. The processor detects a code region and a letter region included in the code image from the code image photographed by the reader. The processor extracts first code information indicating the code image from the code region. The processor also extracts second code information indicating the code image from the letter region.
Claims17
A code recognition apparatus, comprising:
- a reading device that reads a code in a predetermined area, the predetermined area includes a code image and a letter string;
- a memory that temporarily stores the code image which is read by the reading device;
- and
- a processor that
- detects a code region and a letter region included in the code image in the memory,
- performs a distortion correction process to correct geometric distortion of a letter region in the code image stored in the memory,
- performs an OCR process to recognize a letter string after distortion process,
- extracts a first code information represented by the code image from the code region, and
- extracts a second code information represented by the code image from the letter region.
A method for recognizing a code, comprising:
- reading a code image by a reader;
- detecting, by a processor, a code region and a letter region included in the code image from the code image photographed by the reader;
- extracting, by the processor, a first code information represented by the code image from the code region;
- performing a distortion correction process to correct geometric distortion of the letter region,
- performing an OCR process, by the processor, to recognize a letter string in the letter region after the distortion correction;
- and
- extracting, by the processor, a second code information represented by the code image from the letter region.
