Abstract

Quality control of different coatings (colorful, paint, marker, safety, etc.) that are applied to the surface of various objects (both metallic and non-metallic) is an important problem. Also, there is a problem of dealing with counterfeit products. So it’s necessary to distinguish the fake replicas of marking from the authentic marking of producer. To solve these problems, we propose an automated apparatus for analysis and control of spectral reflection characteristics, albedo and color parameters of extended (up to 150 mm × 150 mm) flat objects. It allows constructing the color image of the object surface as well as its multispectral images in different regions of the spectrum. Herewith the color of the object surface can be calculated for various standard light sources (A, B, C, D65, E, F2, F7, F11, GE), or to any light source with a predetermined emission spectrum. The paper presents the description of working principles of the proposed apparatus as well as the results of reflection and multispectral analysis of different flat objects.

分析平面物体反射光谱特征、反照率和颜色参数的仪器的适用范围

应用于各种物体(包括金属和非金属)表面的不同涂层(彩色、油漆、标记、安全等)的质量控制是一个重要问题。此外，还有处理假冒产品的问题。因此，有必要将标识的仿制品与生产者的真品标识区分开来。为了解决这些问题，我们设计了一种自动化装置，用于分析和控制扩展(150mm × 150mm)平面物体的光谱反射特性、反照率和颜色参数。它允许构建物体表面的彩色图像以及其在光谱不同区域的多光谱图像。据此，可以对各种标准光源(A、B、C、D65、E、F2、F7、F11、GE)或具有预定发射光谱的任何光源计算物体表面的颜色。本文介绍了该装置的工作原理，以及对不同平面物体的反射和多光谱分析结果。
