Abstract
Color measurement instruments and processes provide automated and accurate color measurements. Sensor to sample distance is automatically adjusted by the instrument over the course of measurement collection. Adaptive parameters may include turntable speed, illumination spectrum, laser gain setting, number of measurement samples, duration of sampling, sample color measurement threshold, and distance variation measurement threshold.
Claims20
A method of performing non-contact color measurements with a color measurement instrument, comprising
- collecting one or more preliminary measurements of a specific sample with the color measurement instrument, at least one of the preliminary measurements being performed using a default setting;
- adapting the color measurement instrument to the specific sample by automatically adjusting one or more measurement parameters or control points of the color measurement instrument based on the one or more preliminary measurements;
- and
- collecting one or more final measurements of the specific sample using the adaptively adjusted measurement parameters or control points.
A color measurement instrument for performing non-contact color measurements, comprising
- a sensor head for collecting preliminary measurements and final measurements;
- one or more processors configured for
- collecting one or more preliminary measurements of a specific sample with the sensor head, at least one of the preliminary measurements being performed using a default setting;
- adapting the color measurement instrument to the specific sample by automatically adjusting one or more measurement parameters or control points of the color measurement instrument based on the one or more preliminary measurements;
- and
- collecting one or more final measurements of the specific sample with the sensor head using the adaptively adjusted measurement parameters or control points.
A non-transitory computer readable storage medium comprising computer program instructions which, when executed by one or more processors of one or more of an onboard computer, signal processing module, and spectrometer system of a non-contact color measurement instrument, cause the instrument to perform
- collecting one or more preliminary measurements of a specific sample with a sensor head, at least one of the preliminary measurements being performed using a default setting;
- adapting the color measurement instrument to the specific sample by automatically adjusting one or more measurement parameters or control points of the color measurement instrument based on the one or more preliminary measurements;
- and
- collecting one or more final measurements of the specific sample with the sensor head using the adaptively adjusted measurement parameters or control points.
