Abstract
A toy is identified by locating a marker within image data that includes data that represents a toy and data that represents the marker; obtaining one or more marker samples, each of the one or more marker samples including a measured value of a color metric of the marker; determining a color metric offset based on the one or more marker samples and a known value of the color metric of the marker; obtaining one or more toy samples, each of the one or more toy samples including a measured value of the color metric of the toy; applying the determined color metric offset to at least one of the toy samples to determine a corrected color metric of the toy; and identifying the toy as a particular toy based on the corrected color metric of the toy.

A method of identifying a toy as a particular one of a plurality of pre-identified toys, the method comprising:
- locating a marker within image data based on one or more pre-known and optically detectable characteristics of the marker, the image data comprising data that represents a toy and data that represents the marker;
- obtaining one or more marker samples, each of the one or more marker samples comprising a measured value of a color metric of the marker;
- determining a color metric offset based on the one or more marker samples and a known value of the color metric of the marker;
- obtaining one or more toy samples, each of the one or more toy samples comprising a measured value of the color metric of the toy;
- applying the determined color metric offset to at least one of the toy samples to determine a corrected color metric of the toy;
- and
- identifying the toy as a particular one of a plurality of pre-identified toys based on the corrected color metric of the toy.
A toy identification system comprising a detection system configured to capture image data, the detection system being configured to:
- locate a marker within image data based on one or more pre-known and optically detectable characteristics of the marker, the image data comprising data that represents a toy and data that represents the marker;
- obtain one or more marker samples, each of the one or more marker samples comprising a measured value of a color metric of the marker;
- determine a color metric offset based on the one or more marker samples and a known value of the color metric of the marker;
- obtain one or more toy samples, each of the one or more toy samples comprising a measured value of the color metric of the toy;
- apply the determined color metric offset to at least one of the toy samples to determine a corrected color metric of the toy;
- and
- identify the toy as a particular one of a plurality of pre-identified toys based on the corrected color metric of the toy.
A method of identifying a toy, the method comprising:
- determining that a toy is in a toy region of a play surface;
- directing a user to position the toy relative to a detection system such that a first portion of the toy is in the field of view of an optical sensor of the detection system;
- obtaining one or more first portion samples, each of the one or more first portion samples comprising a measured value of a color metric of the first portion of the toy;
- determining a color metric offset based on the one or more first portion samples and a known value of the color metric of the first portion of the toy;
- obtaining one or more toy samples, each of the one or more toy samples comprising a measured value of the color metric of the toy in a second portion of the toy, the second portion of the toy being spatially distinct from the first portion of the toy and being a different color than the first portion;
- applying the determined color metric offset to at least one of the toy samples to determine a corrected color metric of the toy;
- and
- identifying the toy as a particular one of a plurality of pre-identified toys based on the corrected color metric of the toy.
