Abstract
A code reader 1 comprises: a composite processing unit 43 that generates a composite image by executing composite processing of a plurality of images based on image features of each of the plurality of images output from a camera; a decoding unit 45 that executes decode processing on the composite image generated by the composite processing unit 43; a calculation unit 46 that calculates an index indicating the accuracy of the composite processing of the plurality of images by the composite processing unit 43; and an output unit 47 that outputs the index to a management device. The management device displays the index calculated for the composite image on which the decode processing by the decoding unit 45 has failed on a display device.
Claims20
A code reader system comprising:
- a code reader configured to read a code attached to a workpiece conveyed on a conveyor,
- a management device connected to the code reader and a display device, and configured to display information of the code reader on the display device,
- wherein the code reader includes:
- a camera configured to capture the workpiece multiple times,
- a memory configured to store a plurality of images output from the camera,
- a composite processing unit configured to generate a composite image by executing composite processing of the plurality of images based on image features of each of the plurality of images stored in the memory,
- a decoding unit configured to execute a decode processing on the composite image generated by the composite processing unit,
- a calculation unit configured to calculate an index indicating accuracy of the composite processing of the plurality of images by the composite processing unit, and
- an output unit configured to output to the management device a result of the decode processing by the decoding unit and the index calculated by the calculation unit,
- wherein the management device is configured to display on the display device the index calculated for the composite image for which the decode processing by the decoding unit has failed.
A method using a code reader system including a code reader that reads a code attached to a workpiece conveyed on a conveyor, and a management device connected to the code reader and a display device, which displays information from the code reader on the display device,
- the method comprising:
- capturing the workpiece multiple times by a camera of the code reader;
- executing a composite processing on the plurality of images to generate a composite image based on image features of each of the plurality of images, by a composite processing unit of the code reader;
- executing a decode processing on the composite image by a decoding unit of the code reader;
- calculating an index indicating accuracy of the composite processing of the plurality of images by a calculation unit of the code reader;
- outputting a result of the decode processing and the index to the management device by an output unit of the code reader;
- and
- displaying the index calculated for the composite image for which the decode processing failed, on the display device by the management device.
