Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the application provides an ornament, wherein the surface of the ornament is divided into at least one ornament area, and the area of each ornament is set to be a unique color. That is, the regions of each of the ornaments on the surface of the ornament are previously set to a color, and the colors of the regions of the ornaments are different from each other.
In the image including the ornaments obtained by means of photographing or video recording, the preset color of the area of each ornament can be used as a basis for calibrating the colors of other objects in the image, so that the device with the color measurement function can be assisted to accurately measure the actual color of the object in the image.
Specifically, after wearing the ornament, a user holding the ornament can take a picture of the ornament and a part wearing the ornament by using a photographing device, and then analyze the taken picture by using a device or software with a color measurement function. In the analysis process, the preset colors of all the areas of the ornament can be used for calibrating the colors of the skin of the part wearing the ornament in the photo, so that the actual colors of the skin of the part are accurately measured.
When the ornament is used for assisting in measuring the skin color, a user can select to wear the ornament with the color closer to the color of the skin of the user, so that a better calibration effect is obtained.
The principle of using the color of the various ornament regions of the ornament surface for calibrating the color of other objects can be understood as follows: taking a photograph as an example, the deviation between the color of an object in the photograph and the actual color of the object in a photograph is determined by the environment in which the photograph was taken and the parameters of the photographing apparatus used to take the photograph. Therefore, for a good picture, it can be considered that the colors of all objects in the picture are substantially the same as the actual colors (or the color difference of each object in a picture is the same). Then, as long as the color difference of an object in the picture can be determined, the color difference of the object can be regarded as the color difference of all other objects in the picture, so that the color difference can be used to correct the colors of other objects expressed in the picture, thereby obtaining the actual colors of other objects.
Based on the principle, as the color of the area of each ornament is preset, the device (or software) for analyzing the photo to measure the color of the object can predetermine the actual color of the area of each ornament in the photo, and can collect the color of the area of each ornament represented in the photo, thereby calculating the color difference of the area of each ornament according to the actual color of the area of each ornament and the color represented in the photo, and further calibrating the color of other objects represented in the photo by using the calculated color difference to obtain the actual color of the object.
Optionally, the color of the area of each item may be the color in the standard color table, or may be other colors than the standard color table. When a color is set, the color numerical value of such color may be determined.
A color numerical value for a color refers to a number or set of numbers corresponding to a color in a particular color mode. Given a color value, a unique color can be directly determined.
For example, one commonly used color value is the RGB value. The RGB values for a color consist of three numbers, R for red, G for green and B for blue. The color corresponding to an RGB value can be directly determined by designating the RGB value and inputting the RGB value into a computer.
Based on the working principle of the ornaments provided by the embodiment of the application, it can be found that to assist in color measurement by using the ornaments, a device or software for measuring color needs to be capable of obtaining the color numerical values of the actual colors of the regions of each ornament of the ornaments.
In order to achieve the purpose, the ornament can be matched with corresponding color measurement software or equipment and provided for a user, the color numerical values of the actual colors of the areas of the ornaments on the ornament are stored in the corresponding color measurement software or equipment in advance, and the user can directly use the ornament and the corresponding software or equipment.
On the other hand, the ornaments of the application can record the color numerical values (such as RGB values) of the actual colors of the regions of each ornament on the product manual corresponding to each ornament in the form of the product manual, the ornaments and the corresponding product manual are packaged and provided for users, and when the ornaments are required to be used for assisting color measurement, the color numerical values on the product manual are input into color measurement equipment or software.

The film is adhered to the surface of the ornament, so that a plurality of ornament areas with different colors are divided on the surface of the ornament.
Optionally, in view of the implementation manner of the first aspect, a plurality of different films may be provided for one ornament, the color combination of the surface of each film is different, and a user may tear off the film currently adhered to the surface of the ornament according to the need of the user, and then select one of the plurality of films to be adhered, thereby achieving the effect of custom color adjustment.
Wherein each color on each film has a corresponding color value that can be provided to the user in the form of a product manual.
In the second aspect, the surface of the ornament can be provided with a plurality of grooves, color blocks with specific colors are inlaid in each groove, and the inlaid color blocks form the ornament areas with different colors on the surface of the ornament.
Optionally, for the implementation manner of the second aspect, the grooves and the corresponding color blocks may adopt detachable structures, and meanwhile, a plurality of color blocks with different colors are provided for one ornament, so that a user can freely combine the color blocks inlaid on the surface of the ornament as required.

In combination with the accessory provided in any embodiment of the present application, another embodiment of the present application further provides a color measurement method, which can be implemented by running specific software on a smart phone or a personal computer, where the software for implementing the method is software with a color measurement function, and the personal computer or the smart phone running the software is a device with a color measurement function.
As shown in fig. 3, the color measurement method includes the steps of:
s301, acquiring an image to be measured.
The image to be measured is an image including the ornament and the object to be measured provided by the embodiment of the application. The specific object to be measured may be the skin of the face of the user or the skin of other parts, and correspondingly, the image to be measured may be a picture obtained by shooting the face or other parts of the body with the shooting device after the user wears the accessory provided in the other embodiments of the present application, or an image frame in a video.
S302, collecting the color of the ornament area in the image to be measured and the color of the object to be measured in the image to be measured.
The position of the ornament in the image to be measured can be designated by a user, and the position of the ornament can be automatically determined by utilizing an image target detection algorithm.
The object to be measured needs to be specified by the user, the user can specify any object except the ornament in the image to be measured as the object to be measured, and further, the user can specify the specified position of the object to be measured and only measure the color of the specified position.
For example, in a photo taken by a user and including the face of the user and the accessory provided in the embodiment of the present application, the user may display the photo on a smart phone, and then, by clicking a touch screen of the smart phone, specify a position of the accessory and specify a specific area of the face, so that the color measurement software measures the skin color of the face skin in the area.
S303, correcting the color of the object to be measured in the image to be measured based on the color numerical value of the color of the ornament region in the image to be measured and the color numerical value of the actual color of the ornament region.
Step S303 may include the following two specific implementations:
the first method is mainly used when the surface of the ornament is divided into only one ornament area, or the surface of the ornament is divided into a plurality of ornament areas, but only one ornament area can be clearly identified by software.
The first implementation manner comprises the following steps: calculating a difference value between a color numerical value of a color of the area of the ornament in the image to be measured and a color numerical value of an actual color of the area of the ornament acquired in advance.
As previously mentioned, the color values for the actual colors of the regions of the jewelry item may be pre-stored in the color measurement software or may be manually entered by the user while using the color measurement software.
And subtracting the difference value from the color value of the color of the object to be measured in the image to be measured to obtain the color value of the actual color of the object to be measured, and directly determining the actual color of the object to be measured according to the color value of the actual color of the object to be measured.
For example, the RGB values corresponding to the actual color of the region of an ornament are (R1, G1, B1), and the RGB values of the color of the region of the ornament in the image to be measured are (R2, G2, B2), then the difference values of the actual color of the region of the ornament and the color of the region of the ornament in the image to be measured are (R1-R2), (G1-G2), and (B1-B2). Meanwhile, the RGB values of the colors of the object to be measured in the image are acquired (R3, G3, B3), and since the color differences of different objects in the same image are substantially consistent, it can be considered that the RGB values of the actual colors of the object to be measured (R4, G4, B4) can be calculated according to the following formula:
R4＝R3+(R1-R2)；
G4＝G3+(G1-G2)；
B4＝B3+(B1-B2)。
in the above symbols, R1 to R4, G1 to G4, and B1 to B4 are all positive integers.
Optionally, the above calculation process may be replaced by:
and calculating the proportional relation between the color of the area of the ornament in the image to be measured and the color of the object to be measured in the image to be measured.
And calculating to obtain the color numerical value of the actual color of the object to be detected according to the proportional relation and the color numerical value of the actual color of the area of the ornament, so as to determine the actual color of the object to be detected.
The second method is mainly used in the case where the surface of the ornament is divided into a plurality of regions of the ornament, and the regions of at least two ornaments in the image to be measured can be clearly recognized.
The second way includes: and for the areas of the plurality of ornaments which can be identified in the image to be measured, calculating the deviation degree of the colors of the areas of the ornaments in the image to be measured and the colors of the object to be measured in the image to be measured, sorting the areas of the ornaments from small to large according to the deviation degree, and then selecting the areas of the first N ornaments from the sequence, wherein the areas of the selected ornaments are approximate areas. N is a preset positive integer and is less than the number of areas of the ornament that can be identified in the image to be measured.
The second method can be understood as that a plurality of areas with colors closer to the object to be measured are selected from a plurality of areas of the ornament, and then the actual color of the object to be measured is calculated according to the actual colors of the areas of the ornament.
After the approximate area of the object to be detected is determined, the color numerical value of the actual color of the object to be detected can be calculated by utilizing the color numerical value of the actual color of the approximate area, so that the actual color of the object to be detected is determined.
For example, assuming that areas of 5 ornaments on the surface of the ornaments can be identified in the image to be measured, two of them having the smallest deviation can be selected as approximate areas according to the degree of deviation of the colors of the areas of the ornaments in the image to be measured from the color of the object to be measured.
Calculating the color value of the actual color of the object to be measured according to the color value of the actual color of the approximate area, which can be performed by referring to the following processes:
assume that there are two approximate regions (referred to as an approximate region a and an approximate region B, respectively) in the image to be measured, a difference between a color numerical value of a color of the approximate region a in the image to be measured and a color numerical value of a color of the object to be measured in the image to be measured is referred to as a first difference, and a difference between a color numerical value of a color of the approximate region B in the image to be measured and a color numerical value of a color of the object to be measured in the image to be measured is referred to as a second difference.
And after the first difference value and the second difference value are obtained through calculation, subtracting the first difference value from the color value of the actual color of the approximate area A to obtain a first actual color value of the object to be detected, and subtracting the second value from the color value of the actual color of the approximate area B to obtain a second actual color value of the object to be detected.
If the first actual color numerical value is consistent with the second actual color numerical value, the first actual color numerical value can be directly determined as the color numerical value of the actual color of the object to be detected, so that the actual color of the object to be detected is determined.
If the first actual color value is not consistent with the second actual color value, the average value of the first actual color value and the second actual color value can be calculated, and the calculated average value is used as the color value of the actual color of the object to be detected, so that the actual color of the object to be detected is determined.
In addition, after the plurality of approximate areas of the object to be detected are determined, interpolation calculation can be performed by using the actual colors of the plurality of approximate areas of the object to be detected, so that the actual color of the object to be detected is obtained.
According to the color measurement method provided by the embodiment of the application, after the image to be measured is obtained, the color of the object to be measured in the image to be measured is calibrated according to the colors of the areas of the ornaments on the surface of the ornament in the image to be measured and the pre-obtained actual colors of the areas of the ornaments, so that the actual color of the object to be measured is obtained. Based on the technical scheme, the method provided by the embodiment effectively eliminates the color difference of the photo caused by the illumination and the equipment parameters during photographing, so that the actual color of the object to be measured can be accurately measured according to the photo of the object to be measured. Particularly, when the skin of the user is taken as an object to be measured, the skin color of the user can be accurately and objectively measured, and the user can conveniently match the wearing aspect based on the skin color of the user.
In combination with the color measurement method provided by the foregoing embodiment of the present application, another embodiment of the present application provides an electronic device. The electronic device provided in this embodiment may be any device capable of executing the color measurement method provided in any embodiment of the present application, and for example, may be a smart phone or a personal computer or other device for executing the color measurement method provided in this application.
