Detailed Description
Referring to fig. 1, a method of distributing wiring in an embodiment includes steps S110 to S170.
S110: and acquiring a color value and a color element value corresponding to the cloth to be wired.
Color values refer to the corresponding color values in a color mode. The color element value refers to a parameter value for representing a color attribute, and may include at least one of lightness, hue, and saturation. The color mode may be any of an RGB mode, a Lab color mode, a CMYK mode, an HSB mode, and the like, and a parameter indicating a color is associated with each color mode. For example, the parameters representing the color in the RGB mode include three values of R, G, and B, and when the RGB mode is used to represent the color, the color values include the R, G, and B values; the parameters for representing the color in the Lab color mode comprise three values of an L value, an a value and a b value, and when the Lab color mode is used for representing the color, the color value comprises the L value, the a value and the b value.
The color value and the color element value corresponding to the cloth to be wired may be obtained by receiving input information, for example, a worker manually inputs the color value and the color element value after determining the color value and the color element value of the cloth to be wired, in this case, step S110 includes: and receiving the input color value and the color element value to obtain the color value and the color element value corresponding to the cloth to be wired. The color value and the color element value corresponding to the cloth to be wired may also be obtained by searching, for example, the database stores in advance the corresponding relationship between the cloth identification information of each cloth and the color value and the color element value, where the cloth identification information refers to a mark for identifying the cloth, such as a name or a number, and the worker inputs the cloth identification information, and correspondingly, step S110 includes: and searching the corresponding color value and color element value according to the input cloth identification information to obtain the color value and color element value corresponding to the cloth to be wired.
S130: and acquiring color values of the alternative lines of a plurality of color numbers.
The color number indicates a symbol number for representing a color; the alternative line refers to a standby line which can be matched with the cloth to be distributed; the plurality of color numbers refer to two or more color numbers. One color number may correspond to one or more alternative lines, for example, if all alternative lines are provided by the same supplier, one color number corresponds to one alternative line; if there are several suppliers providing the optional lines, one color number may correspond to several optional lines and different suppliers. Specifically, step S130 may include: and searching the color values corresponding to the alternative lines of the plurality of color numbers from the database.
The execution sequence of step S130 and step S110 is not limited, that is, step S110 may be executed first, step S130 may be executed first, or step S110 and step S130 may be executed simultaneously.
S150: and respectively acquiring the color difference between the cloth to be distributed and each alternative line according to the color value, the color element value and the color value of the cloth to be distributed.
Color difference refers to a difference value of colors; the size of the color difference reflects the difference between the color corresponding to the color number of the alternative line and the color of the cloth to be wired. The smaller the color difference is, the smaller the difference between the color corresponding to the color number of the corresponding alternative line and the color of the cloth to be wired is.
S170: and selecting a line matched with the cloth to be wired from the corresponding alternative lines according to the plurality of color differences.
The number of color differences is equal to the number of candidate lines. According to the color difference matching line, the matching can be carried out according to the size of the color difference. Specifically, step S170 may include: and selecting the minimum color difference from the plurality of color differences, and taking the alternative line corresponding to the minimum color difference as a line matched with the cloth to be wired. It is understood that step S170 may further include: and selecting a color difference smaller than a preset value from the plurality of color differences, and taking an alternative line corresponding to the selected color difference as a line matched with the cloth to be wired. Alternatively, step S170 may further include: and sequencing the plurality of color differences from small to large, and taking the alternative lines corresponding to the color differences with the preset number in the front ranking as lines matched with the cloth to be wired.
The cloth wiring method comprises the steps of obtaining a color value corresponding to the cloth to be wired, a color element value and color values of multiple color number alternative lines, respectively obtaining the color difference between the cloth to be wired and the alternative lines according to the color value, the color element value and the color value of the alternative lines, and selecting lines matched with the cloth to be wired from the corresponding alternative lines according to the color differences; therefore, the lines matched with the cloth to be distributed can be automatically selected, the color difference analysis of human eyes by workers is not needed, the difference caused by human eye judgment can be avoided, and the distribution accuracy is improved; simultaneously, through automatic matching, can reduce artifical working strength and improve distribution efficiency.
