In industrial production, there are often high demands on the overall color of the product, or the color of the surface coating. When the color of the product deviates or the color of the product needs to be changed or upgraded, the formula and the process parameters of the product need to be adjusted.
In the prior art, under the condition that the color of a product deviates or the color of the product needs to be replaced or upgraded, some products are adjusted through manual visual inspection, and some products are debugged through a spectrophotometer.
Under the condition of debugging through manual visual inspection, debugging is carried out according to the experience of debugging personnel, and under the condition, the subjective factor is large, and the requirement on the experience of the debugging personnel is high.

Fig. 1 is a flowchart illustrating a product color correction method according to an embodiment of the present invention.
As shown in fig. 1, a product color correction method according to an embodiment of the present invention includes:
acquisition step S100: shooting a product on a product production end by using a mobile terminal to obtain the current color parameter of the product;
correction step S200: correcting the current color parameters of the products obtained in the step S200 at the mobile terminal, outputting the corrected current color parameters of the products and sending the corrected current color parameters to the background server;
a comparison step S300: comparing the corrected current color parameter with a target color parameter by a background server, and outputting a color parameter deviation between the corrected current color parameter and the target color parameter;
correction step S400: pre-storing a first corresponding relation between the color parameter deviation and a formula correction scheme of the product color, and obtaining the formula correction scheme of the product color corresponding to the color parameter deviation output in the comparison step based on the first corresponding relation; and
a transmission step S500: and sending the formula correction scheme to the production end to adjust the formula of the production end.
Next, specific contents of these steps will be described.
In the obtaining step S100, a mobile terminal is used to photograph a product on a product production end, and the mobile terminal is used to analyze an imaging result, and capture a color parameter in the imaging, that is, a current color parameter of the product.
The color parameter used most commonly here is the RGB parameter, but the present invention is not limited to the RGB parameter, and may be a CMYK parameter, for example. In the case of using the RGB parameters, for example, after the mobile terminal takes a picture of a product, a point on the imaged picture is manually selected to read the color parameters, that is, a certain position of the imaged picture is clicked, and then the values of the RGB parameters at the position can be read. Thus, color parameters can be easily collected at any position on the product, which is not possible with conventional spectrophotometers.
Next, in the correction step S200, the acquired color parameters may be corrected specifically as follows, as an example:
preparing a colorimetric standard product;
photographing the colorimetric standard under the same photographing conditions as in the obtaining step S100 and obtaining color parameters of the colorimetric standard as in the obtaining step S100;
and correcting the color parameters of the product obtained in the obtaining step S100 according to the color parameters of the colorimetric standard, thereby obtaining the corrected color parameters of the product.
Here, the same photographing conditions refer to, for example, assuming that a table on which products and colorimetric standards are photographed can provide an environment suitable for photographing (including light source intensity, direction, photographing angle, and the like).
Alternatively, as another example, the correction may also be performed as follows:
in the obtaining step S100, the product and the colorimetric standard prepared in advance are simultaneously photographed under the same photographing conditions, and then RGB parameters of the product and the colorimetric standard are respectively read to obtain RGB parameters of the product and RGB parameters of the colorimetric standard. Then, in a correction step S200, the RGB parameters of the product are corrected based on the RGB parameters of the colorimetric standard, so as to obtain the color parameters of the corrected product.
The color parameters and the formula information corresponding to the color parameters are stored in the background server in advance, the color parameters in the background server are also relative parameters after the color standard is corrected, a first corresponding relation between the color parameter deviation and the formula correction scheme of the product color is stored in the background server in advance, and the formula correction scheme of the product color corresponding to the color parameter deviation output by the comparison step is obtained in the correction step S400 based on the first corresponding relation. Further, in the modification step S400, after the background server receives the corrected color parameters (also referred to as relative color parameters) of the actually produced product sent from the mobile terminal, the corrected color parameters are compared with the originally designed target color parameters stored in the database of the background server, and according to the deviation thereof, the background server calculates the possible reason for the deviation according to the database thereof. Specifically, for example, the following sub-steps may be included in the correction step S400:
pre-storing a first corresponding relation between the color parameter deviation and a formula correction scheme of the product color and pre-storing a second corresponding relation between the color parameter deviation and a related possible reason;
obtaining a formula correction scheme of the product color corresponding to the color parameter deviation and related possible reasons according to the first corresponding relation and the second corresponding relation based on the comparison result; and
a plurality of recipe correction scenarios with a priority order are pushed based on the probability order of occurrence of each cause.
Preferably, recipe correction schemes such as Top3 (Top three digits) or Top5 (Top five digits) may be pushed according to the order of the probability of each problem occurring.
As an example, the following table is used to push the data in order of probability of possible cause from top to bottom.
Possible causes of color parameter deviations | Probability of possible cause | The main content of possible causes | Recipe correction scheme |
Possible reasons (1) | 90% | Adding additive AA | Recipe correction scheme 001 |
Possible reasons (2) | 80% | Reduced additive BB | Recipe correction scheme 002 |
Possible reasons (3) | 75% | Adding additive CC | Recipe correction scheme 003 |
Possible reasons (4) | 70% | Reduce additive DD | Recipe correction scheme 004 |
Possible reasons (5) | 60% | Increased additive EE | Recipe correction scheme 005 |
The product color correction method of the present invention can be applied to a process of coating/coloring or the like of various industrial products, and for example, correction of the color of the following products can be exemplified: polyurethane coatings, polycarbonates, and polycarbonate compositions, wherein the polyurethane coating comprises a polyurethane waterborne coating.
