Abstract

The invention discloses an optimization method and device for scanning paths of a galvanometer. The method comprises the following steps that an initial scanning path set S of the galvanometer and a scanning filling distance m are acquired; according to the scanning sequence of each scanning path in the initial scanning path set S and the scanning filling distance m, an optimized scanning path ofthe galvanometer is determined; and the galvanometer is controlled to perform scanning according to the optimized scanning path. Compared with the prior art, the galvanometer is not strictly scanned according to the scanning sequence of each scanning path in the initial scanning path set S, and the scanning sequence of each scanning path and the scanning filling distance are determined according to the scanning sequence of each scanning path and the scanning sequence of each scanning path, so that a new optimized scanning path is determined; and the optimized scanning path can effectively reduce the total length of the galvanometer during scanning of the model hollow area, so that the scanning time of the galvanometer can be shortened, and the 3D printing efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping, in particular to a method and device for optimizing the scanning path of a vibrating mirror. Background technique [0002] Vibrating mirror, also called laser scanner, generally consists of X-Y optical scanning head, electronic drive amplifier and optical mirror. The signal provided by the computer controller drives the optical scanning through the driving amplifier circuit, so as to control the deflection of the laser beam on the X-Y plane. [0003] At present, when planning the scanning path of the galvanometer, the galvanometer generally scans one by one in strict accordance with the actual filling sequence. For details, see figure 1 , figure 1 It is a schematic diagram of the common galvanometer scanning path in the prior art, in figure 1 In , the solid line part indicates the scanning path of the galvanometer corresponding to the solid part of the model, and the dotted line part...
