Determining the color of a multi-colored object with relatively large dimensions

Abstract

The use of standard instruments (colorimeters) when measuring the color coordinates and chromaticity of multicolored objects and having relatively large dimensions is practically impossible. This is due to the fact that ordinary colorimeters, no matter what method is implemented in them, are designed to determine the color of a specific point of the measured object. This article discusses a method for determining the color of a multicolored and relatively large object, for example, a car, color photography, art painting, etc. Let us call this method computer colorimetry. A practical solution to this method can be used in such areas of the national economy, as, for example, repainting a car after damage to certain parts of the body with damage to the paintwork, automatic control and video surveillance of forest and peatland areas to detect fires, in the examination of the authenticity of documents and works of art, and other areas of the national economy.
