High-accuracy chromaticity imaging device, and chromaticity imaging method thereof

Abstract

The invention relates to a high-accuracy chromaticity imaging device, and a chromaticity imaging method thereof. The device comprises a closed camera obscura, a standard light source, a chromaticity collection sensor, a movement mechanism and a target substance collection area, wherein the chromaticity collection sensor is arranged on the movement mechanism to carry out surface scanning on a target substance collection area under the driving of the movement mechanism. The method comprises the following steps that: the movement mechanism drives the chromaticity collection sensor to carry out the surface scanning on the whole target substance collection area; the chromaticity value of each point in the target substance collection area is collected to form a surface chromaticity diagram corresponding to the whole target substance collection area; then, through a segmentation algorithm, a target substance and the background of the target substance are segmented; the surface chromaticity diagram of the target substance is extracted; and finally, through a mean value algorithm, the surface average chromaticity of the target substance is calculated. By use of the device and the method, collecting and imaging efficiency is high, the surface chromaticity of the target substance can be automatically collected, and in addition, the device and the method are easy in operation and good in use effects.

Description

technical field [0001] The invention relates to the technical field of chromaticity acquisition, in particular to a high-precision chromaticity imaging device and a chromaticity imaging method thereof. Background technique [0002] Various professional equipments for chromaticity acquisition have been disclosed in the prior art. For example, the invention patent with the application number 201621441180.8 discloses a scanner and chromaticity recognition equipment. The improvement of the chromaticity scanner is only to set multiple windows and place different substances for data collection. Compared with the previous single window, there is no need to The standard substance and the target substance are placed successively for collection, which improves the efficiency, but the chromaticity value of a single point is still collected, and the chromaticity value of the entire surface of an object cannot be obtained. Contents of the invention [0003] The purpose of the present ...
