Abstract
In a shoe fit evaluation system, a dimensional difference calculator calculates a part dimensional difference, which is a difference between a measurement value of a foot part dimension and a last part dimension corresponding to the foot part, by performing a certain adjustment for the part. An evaluation processor calculates a last matching rate based on the part dimensional difference. An outputter outputs information regarding the last matching rate. The dimensional difference calculator calculates the part dimensional difference by performing, as the certain adjustment, subtraction of an allowance for specific stretch properties of each shoe part.
Claims18
A shoe fit evaluation device, comprising:
- a three-dimensional foot shape measuring device or measurement mat configured to receive a foot of a measurement subject and be used to acquire three-dimensional data regarding a foot shape of the foot;
- a measurement value acquirer configured to acquire measurement values of a plurality of foot part dimensions based on the three-dimensional data regarding the foot shape, which are dimensions of a plurality of foot parts including at least a foot length, as foot shape dimension information that defines the foot shape of the measurement subject;
- a last storage configured to store, for each of a plurality of types of lasts, a plurality of last part dimensions, which are dimensions of last parts corresponding to the plurality of foot parts including at least the foot length, as last dimension information that defines a last;
- a dimensional difference calculator configured to calculate a part dimensional difference, which is a difference between a measurement value of a foot part dimension of the plurality of foot part dimensions and a last part dimension of the plurality of last part dimensions corresponding to a foot part of the plurality of foot parts, by performing a predetermined adjustment for the foot part;
- an evaluation processor configured to calculate a last matching rate based on the part dimensional difference;
- and
- an outputter configured to output information regarding the last matching rate.
A shoe fit evaluation method, comprising:
- receiving a foot of a measurement subject and acquiring three-dimensional data regarding a foot shape of the foot using a three-dimensional foot shape measuring device or a measurement mat;
- acquiring measurement values of a plurality of foot part dimensions based on the three-dimensional data regarding the foot shape, the plurality of foot part dimensions being dimensions of a plurality of foot parts including at least a foot length, as foot shape dimension information defining the foot shape of the measurement subject;
- retrieving, from a predetermined storage device, a plurality of last part dimensions, the plurality of last part dimensions being dimensions of last parts corresponding to a plurality of foot parts including at least the foot length, as last dimension information defining a last;
- calculating a part dimensional difference, the part dimensional difference being a difference between a measurement value of a foot part dimension and a last part dimension corresponding to the foot part, by performing a predetermined adjustment for the foot part;
- calculating a last matching rate based on the part dimensional difference;
- and
- outputting information regarding the last matching rate.
