the engraving track generation module is used for generating a track required to be engraved by the galvanometer according to the graph stored in the storage module and transmitting the track required to be engraved by the galvanometer to the control device, and the control device controls the galvanometer to perform laser engraving according to the track required to be engraved generated by the engraving track generation module.
9. The apparatus of claim 8, wherein the control device further comprises a comparison module for comparing in real time whether the actual engraving trajectory of the galvanometer captured by the camera module coincides with the trajectory of the required engraving of the galvanometer generated by the engraving trajectory generation module, and if the actual engraving trajectory of the galvanometer captured by the camera module deviates from the trajectory of the required engraving, the control device controls the galvanometer to stop and adjusts the parameters of the galvanometer according to the trajectory of the required engraving.
10. The apparatus of claim 8, wherein the engraving trajectory generating module is configured to generate a trajectory to be engraved by the galvanometer based on the pattern stored in the storage module, the method specifically comprises the steps of analyzing stored graphs, collecting the graph with the lightest color to generate a first carving track if the graphs have the gradually changing depth of the same color, sequentially generating a second carving track and a third carving track from light to deep according to the color, wherein the second carving track and the third carving track are the Nth carving track, the first carving track, the second carving track and the third carving track are used for determining a first carving parameter, a second carving parameter and a third carving parameter according to the color depth degree, and the first carving parameter, the second carving parameter and the third carving parameter are stored in the storage module.
