Paper Abstract

In this paper, we discuss a color measuring system, which is based on the measurement of the wavelength spectrum of an object of interest. The design of measuring head, the correction of errors in the measuring and color recognition and analysis methods for an intelligent colorimeter are studied and discussed. We have described a compact and shock resistant measuring head for color spectrum measurements. It is shown that the cut of a spectrum from the 640 nm can be corrected quite accurately by linear extrapolation function in the sense of error in CIELAB coordinate values. For construction of an adaptive color measurement system, the subspace network or the Multi-Layer-Perceptron network can be used as an intelligent method for spectral analysis and recognition.
