摘要： As described herein, a method has been developed to estimate the gloss of a black or dark sample using a color measurement system. In such a system, when measuring a higher gloss sample, more illumination light reflected from the sample surface will be directed away from the receiving sensor, and thus less signal will be detected. Using a derived sensor-signal to surface-gloss relationship, the surface gloss of a sample can be calculated by applying the measurements of the sample to the signal to gloss relationship to obtain a more accurate gloss measurement of a sample under analysis.

摘要： A method and a system are provided for obtaining improved spectra recovery results of a measurement of a sample through the use of a calibration matrix obtained from calibration measurement values using at least one illumination source. By calculating the reflectance spectrum of a collection of calibration samples across several rounds of measurements and cascading the results, an improved calibration matrix can be used to convert the sample measurement values to more accurate results.

摘要： A method and a system are provided to measure transmittance or reflectance of a color specimen by using a transformation matrix obtained from the measurement values of a series of known transmittance or reflectance calibration color standards and multiple flashes from different illumination sources. A color spectrum can be determined with reduced error by calculating the reflectance spectra of an object using measurement matrices obtained under at least two illuminants and the transformation matrix.

摘要： A method has been developed to monitor the aging of an illuminator (such as a lamp) and the interior sphere wall in a sphere-based color measurement instrument. This monitoring process or method is configurable to independently monitor the aging of the illuminator as well as the aging of the interior surface of a color measurement device using standard calibration measurements already present in the color measurement device.

摘要： A method has been developed to improve the stability of a color measurement system that measures reflectances using matrix-transformation method. The transformation matrix can be obtained by training with a raw measurement matrix and a master reflectance matrix. The raw measurement matrix can be stacked with one or more of its variations, with each variation being some random noise added onto a part or the whole original raw signal matrix. The same number of master reflectance matrices are also stacked to match the size and sample ordering of the raw measurement matrix. The resulting transformation matrix will be more stable and less sensitive to the measurement noise.

摘要： A system including a processor and a memory configured to store code executed by the processor is provided. In one or more implementations, the processor is configured by the code to calibrate measurements made by color measurement devices. In one particular implementation, the processor receives a measurement dataset of one or more color values, for a sample obtained by a color measurement device. The processor is configured to convert the measurement dataset to a standard space measurement dataset using a standard space measurement model and calculate a color dataset based on the standard space measurement dataset using a color conversion model. The processor is further configured to output the calculated color dataset to at least one of a display, database or local memory store.

摘要： A method is provided for identifying colors across illuminants using a processor configured by code executing therein, the method comprising capturing a sample image with an image recording device, the image including pixels resenting a color sample under analysis and a color reference chart. The processor is also configured to execute comparing the color values of pixels representing the color reference chart of the sample image to the pixel values corresponding to a plurality of entries within a plurality of color reference datasets to determine the color reference having the closest match of sample captured in the image. The reference identifier of the color that is the closest match to the sample is then output for further use.

摘要： An apparatus and method for providing a solution that enables technicians or other technical professionals to obtain accurate gloss, haze and DOI values for a reflecting sample due to the surface conditions of the sample. The apparatus and method allow for the generation of a data model of the surface of a sample using a sensor array designed to detect the divergence of a collimated beam of light reflected off the surface of the sample. The same principle enables technical professionals to obtain accurate haze and clarity values for a transparent or translucent sample that is trans-illuminated by light.
