Abstract
To suppress an increase in processing time due to a load of inference processing while improving reading accuracy by the inference processing of machine learning. An optical information reading device includes a processor including: an inference processing part that inputs a code image to a neural network and executes inference processing of generating an ideal image corresponding to the code image; and a decoding processing part that executes first decoding processing of decoding the code image and second decoding processing of decoding the ideal image generated by the inference processing part. The processor executes the inference processing and the first decoding processing in parallel, and executes the second decoding processing after completion of the inference processing.
Claims20
An optical information reading device for reading a code attached to a workpiece, the optical information reading device comprising:
- a camera configured to capture an image of the code and generate a first image containing the code;
- a storage unit configured to store information of a neural network;
- and
- a processor including at least one core and a neural processing unit,
