Abstract
In evaluation of the print quality of a symbol, the evaluation processing takes time. A symbol evaluation device (5) includes: a decoding unit (52) that decodes a symbol included in an image and thereby identifies reference position information of the symbol; a module position identification unit (53) that identifies a plurality of module positions included in the symbol on the basis of the reference position information of the symbol identified by the decoding unit; and a quality evaluation unit (54) that evaluates the quality of the symbol on the basis of the plurality of module positions identified by the module position identification unit.
Claims15
A symbol evaluation device, comprising:
- a processor, configured to:
- decode a symbol included in an image and thereby identifies reference position information of the symbol, wherein the reference position information of the symbol comprises position information of a symbol position detection pattern or position information of a module position detection pattern determined for each type of symbols;
- identify a plurality of module positions included in the symbol on the basis of the reference position information of the symbol comprising:
- identifying a partial region comprising modules that constitute at least a part of the symbol position detection pattern or the module position detection pattern in the image on the basis of the position information of the symbol position detection pattern or the position information of the module position detection pattern;
- identifying a pattern reference position of the symbol position detection pattern or the module position detection pattern according to the partial region,
- identifying the plurality of module positions included in the symbol on the basis of the pattern reference position;
- and
- evaluate a quality of the symbol on the basis of the plurality of module positions.
A symbol evaluation method, comprising:
- a decoding step of decoding a symbol included in an image and thereby identifying reference position information of the symbol, wherein the reference position information of the symbol comprises position information of a symbol position detection pattern or position information of a module position detection pattern determined for each type of symbols;
- a module position identification step of identifying a plurality of module positions included in the symbol on the basis of the reference position information of the symbol identified in the decoding step, wherein the module position identification step comprising:
- identifying a partial region comprising modules that constitute at least a part of the symbol position detection pattern or the module position detection pattern in the image on the basis of the position information of the symbol position detection pattern or the position information of the module position detection pattern;
- identifying a pattern reference position of the symbol position detection pattern or the module position detection pattern according to the partial region,
- identifying the plurality of module positions included in the symbol on the basis of the pattern reference position;
- and
- a quality evaluation step of evaluating the quality of the symbol on the basis of the plurality of module positions identified in the module position identification step.
