摘要： A surface characteristics evaluation method for evaluating a surface characteristic of a painted surface including a glittering material, including: a multi-angle condition image acquisition step S101 for acquiring a multi-angle condition image including multi-angle conditions in a continuous manner by performing an image-capturing process to capture how a reflection condition of the painted surface changes when rotating an illumination device 2 emitting light onto the painted surface, the image-capturing process being performed by the line scan camera 4 while a sample P having the painted surface is moved in a certain direction; an in-plane chromaticity distribution acquisition step S102 for acquiring an in-plane chromaticity distribution of the painted surface from the multi-angle condition image acquired; and a surface characteristics evaluation step S107 for calculating particle characteristics S as surface characteristics evaluation values of the multi-angle conditions, on the basis of the in-plane chromaticity distribution acquired.

摘要： A colorimetric compliance control device includes a electronic communication device, a non-transitory computer readable medium, an electronic controller. The electronic communication device is programmed to electronically receive colorimetric information regarding a vehicle component. The non-transitory computer readable medium electronically stores a non-transitory computer learning model using the colorimetric information acquired by the detector as a first input. The non-transitory computer learning model generates a colorimetric value as an output value related to the colorimetric information. The electronic controller is programmed to compare the output value with a predetermined exemplary value. The electronic controller is programmed to determine when the output value deviates from the predetermined exemplary value.

摘要： Methods and software applications for transmitting high-resolution spectral curve data to a tinter for generating a tint formula usable to custom-tint a base paint or coating to match the color of a sensed surface. The high-resolution spectral curve data is derived from low-resolution or wideband spectral data obtained via a low resolution or wideband spectrophotometer. Additional user information, order information, or location information may be transmitted to the tinter.

摘要： A monitoring procedure for monitoring the quality of measurement spectra of a liquid medium continuously determined with a spectrometric sensor, which spectra in each case reproduce spectral values in a specified measurement wavelength range, is described with which: for each measurement spectrum, a quality parameter of the respective measurement spectrum is determined in each case based upon at least one characteristic value calculated in each case based upon the spectral values of the respective measurement spectrum, wherein each characteristic value for each measurement spectrum is determined in each case based upon the spectral values of the respective measurement spectrum in a range, specified for the respective characteristic value, of the measurement wavelength range, and, based upon the quality parameters, those measurement spectra which have spectral values that are impaired by a disturbance are identified as outliers.

摘要： A color measuring system includes a processor configured to perform color measurement, configured to receive designation of a color sample book, configured to, in response to the color measurement being performed, compare colors of the color sample book and a color measured by the color measurement and automatically select a color close to the measured color out of the color sample book, and configured to notify, together with the measured color, the selected color to a user as an approximate color of the measured color.

摘要： The image processing device (during learning) converts RGB color space of an input image and a label image into CIELAB color space and performs learning using a color difference between an inferred image and the label image as an error. The image processing device (during inference) converts RGB color space of an input image into CIELAB color space and creates an inferred image using the CIELAB input image.

摘要： A method and a device for determining a yellowish level of a screen caused by pressing are provided. The method includes: acquiring chromaticity coordinates of a plurality of test points of the screen during a pressing test; processing the acquired chromaticity coordinates, so as to acquire a chromatic aberration between the test point with a maximum value of X or a maximum value of Y in the chromaticity coordinates and the test point with a minimum value of X or a minimum value of Y in the chromaticity coordinates; and comparing the chromatic aberration with a predetermined standard chromatic aberration, so as to determine whether the screen is qualified after the pressing test.
