1. A lighting control method, comprising:
receiving light-emitting color data, the light-emitting color data including color values corresponding to a plurality of preset light-emitting channels;
determining at least one additional light-emitting channel other than the plurality of preset light-emitting channels among the actual light-emitting channels of a lighting device;
generating a color value of the additional light-emitting channel according to color values of the plurality of preset light-emitting channels in the light-emitting color data, and using the color values corresponding to the plurality of preset light-emitting channels and the additional light-emitting channel as target light-emitting color data; and
transmitting the target light-emitting color data to each lamp bead chip in the lighting device to control corresponding lamp beads to emit light according to the color values corresponding to the actual light-emitting channel to which the lamp beads belong,
wherein generating a color value of the additional light-emitting channel according to color values of the plurality of preset light-emitting channels in the light-emitting color data further comprises:
according to the color value of each preset light-emitting channel in the light-emitting color data, determining a maximum value and a minimum value, and calculating a saturation;
matching a corresponding brightness ratio according to the saturation, and matching corresponding weights of the color values of the preset light-emitting channels in the light-emitting color data, and calculating a first color value, wherein the first color value is used as a color value of the additional light-emitting channel, and the additional light-emitting channel is a single channel and is used to emit white light; or, based on corresponding weights matched with color values of the additional light-emitting channels, and the first color value, determining the color values of the additional light-emitting channels, wherein the additional light-emitting channels include two different light-emitting channels that emit white cold light and white warm light respectively; and
using the color value of each preset light-emitting channel specified by the lighting color data as the color value corresponding to the same light-emitting channel in the actual light-emitting channels, and constructing the color values of the light-emitting channels in the actual light-emitting channels as target lighting color data.
