Research on design and implementation of high precision imaging colorimeter system

As an important parameter to characterize the apparent characteristics of objects, color plays an irreplaceable role in various fields. With the increasing demand for color quality, special color detection instruments are needed to measure color quickly and accurately. However, the current traditional color measuring instrument has some limitations, it is difficult to accurately measure the color of a certain part of the complex pattern, and it is very easy to miss the image information of the object surface.With the continuous development of machine vision technology and spectrum technology, hyperspectral imaging technology came into being. The advantage over traditional color detection instruments is that hyperspectral imaging technology obtains spectral and spatial information at the same time, so as to achieve accurate color detection.In this paper, machine vision technology and hyperspectral imaging technology are applied to the field of color measurement, and a high precision imaging colorimeter system is designed and developed. Compared with the traditional three-channel color detection instrument, the system has more spectral information carried by hyperspectrum, so it can more accurately restore the true color of the item, so as to achieve high-precision color detection.
