Referring to fig. 1, the method may specifically include the following steps:
s101, determining a target pantone color system according to set production requirement information, and storing color data of the target pantone color system into a pantone color system standard library.
The set production requirement can be an industry requirement or a requirement of an application scene, for example, when the method is applied to the printing and dyeing industry, a pantone system commonly used in the printing and dyeing industry is determined as a target pantone system, and then color data of the target pantone system is stored in a pantone system standard library. The basic color data in the pantone color system standard library is maintained, and is not fixed and unchanged, and is updated according to the color change commonly used in the international standard. The pantone System standard library may exist in an existing ERP (Enterprise Resource Planning) System, MES (Manufacturing Execution System), or the like, and may exist in a database independently in the role of third-party technical support software.
Optionally, the target pantone color system comprises a color system of a pantone paper color card and a color system of a pantone polyester color card; the target pantone color system comprises a color name, a color number, three primary color data of the color, the hue of the color, the brightness of the color and the saturation of the color. The three primary color data mainly refers to R (Red), G (Green), and B (Blue, Green).
S102, collecting first color data of the cloth to be identified.
The first color data of the cloth to be identified can be collected by the color collecting device, and optionally, the color collecting device can adopt a unified civil mobile phone camera, a professional camera and the like, and the color collecting device is matched with a standard light source provided by the color lamp box to complete color collection.
It should be noted that there is no obvious precedence relationship between S101 and S102, which is only an example, that is, there is no obvious precedence relationship between the process of the pantone color system standard library and the process of acquiring the color data of the cloth to be identified, and S102 and then S101 may be executed first.
S103, determining the target color of the cloth to be identified according to the first color data and the second color data of each color in the pantone system standard library.
Specifically, in order to distinguish from the first color data to be recognized, the color data of a plurality of colors included in the pantone color system standard library are referred to as second color data, and then a distance algorithm and a similarity algorithm may be applied to determine the target color of the cloth to be recognized. In a specific example, the distance algorithm may be to determine a distance between two color data, where a color corresponding to the second color data with the shortest distance is a target color; and the color corresponding to the second color data with the maximum similarity is the target color.

On the basis of the technical scheme, the target color of the cloth to be identified is determined according to the first color data and the second color data of each color in the pantone color system standard library, and the method can be realized in the following mode: calculating the similarity of the first color data and each second color data according to the three primary color data of the first color data, the three primary color data of the second color data and a set included angle cosine algorithm; and determining the color in the pantone color system standard library corresponding to the second color data with the highest similarity as the target color of the cloth to be identified.
In a specific example, also taking the RGB expression form as an example, the first color data is referred to as a, the second color data is referred to as B, RGB of a is referred to as (R1, G1, B1), and X is (X) respectively1,x2,x3) RGB of B is (R2, G2, B2), and Y is (Y)1,y2,y3) Then, X and Y are respectively substituted into a cosine calculation formula:
where θ represents the angle between space vectors X and Y, n is 3, and i is 1, 2, and 3. And cos (theta) is the similarity, and the color in the pantone color system standard library corresponding to the second color data with the highest similarity is the target color of the cloth to be identified.
In addition, the target color which is determined to be unavailable in the world through the distance and the similarity belongs to the selectable configuration item of the customized color distinguishing logic module, and the adaptability of the method to different production environments is further improved.
