Example 2
The embodiment provides an evaluation method of color block matching degree of a ship cabin, which is a further improvement on the basis of embodiment 1.
In this embodiment, since the brightness value representing the brightness state of each color block and the chroma value representing the chroma state both exist in a numerical form, and the hue identifier representing the hue state of each color block exists in a character form, before calculation, the hue identifier needs to be converted into a hue value in a numerical form.
Based on this, a hue conversion table may be preset before the color value corresponding to each color patch is obtained, where the hue conversion table includes a one-to-one correspondence relationship between hue identifiers and hue values.
Next, the hue identifier, the brightness value, and the chroma value of each color block may be extracted, and the hue identifier is converted into the corresponding hue value by using the hue conversion table.
Preferably, the embodiment can adopt a Munsell (Munsell) color system to design the hue conversion table. In the Munsell (Munsell) color system, hue is a characteristic used primarily to distinguish different colors. This embodiment can select five dominant hues: red, yellow, green, blue, violet, five intermediate colors can also be selected: red yellow, yellow green, green blue, blue violet, and purplish red. The colors are arranged in a ring shape and divided into 100 uniform points (each hue is further divided into 10, and the total number of hues is 100). The hue marks R are defined as red, YR as red yellow, Y as yellow, GY as yellow-green, G as green, BG as green-blue, B as blue, PB as blue-violet, P as violet, RP as magenta, etc. For convenience of calculation, the hue marks can be converted into numerical values, and table 1 shows hue marks mainly related to color patches in the ship cabin and hue values corresponding to the hue marks. In specific application, a curve with the abscissa as the hue mark and the ordinate as the hue value can be fitted according to the parameters in table 1, and for hue marks (for example, 6R) not related in table 1, the hue value corresponding to the hue mark can be found by using an interpolation method in the prior art according to the rule of the curve.
