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 that reads a code attached to a workpiece, the optical information reading device comprising:
- a camera that captures an image of the code and generates a code image;
- a storage that stores a structure and a parameter of a neural network configured to estimate an ideal image corresponding to the code image generated by the camera;
- and
- a processor including an inference processing part that inputs the code image generated by the camera to the neural network configured using the structure and parameter stored in the storage and executes inference processing of generating the ideal image corresponding to the code image, and a decoding processing part that executes first decoding processing of decoding the code image generated by the camera and second decoding processing of decoding the ideal image generated by the inference processing part,
- wherein the processor is configured to execute the inference processing by the inference processing part and the first decoding processing by the decoding processing part in parallel, and execute the second decoding processing by the decoding processing part after completion of the inference processing by the inference processing part.
