Numerical control laser engraving machine, control system, control method and computer

Abstract

The invention belongs to the technical field of numerical control engraving, and discloses a numerical control laser engraving machine, a control system, a control method and a computer. The control method comprises the steps that a set of circularly photographing graph sequences are obtained through a camera through a CAD graphic module, so that CAD engraving graphic data of a to-be- engraved product is obtained; moreover, the data are preprocessed through a signal processor and then are sent to a graphic processing module for analysis of the CAD engraving graphic data of the to-be-engraved product; the analyzed data is input into a single-chip microcomputer to be compiled by an engraving program; and an instruction of the compiled program is sent to a core board module, an instruction motor drives a laser to slide back and forth in a guide rail, and engraving of the whole graph is completed. According to the numerical control laser engraving machine, the control system, the control method and the computer, fine engraving can be carried out by utilizing laser, a computer numerical control technology is used and can be well combined with a laser processing system so that requirements for industrial mass production can be met, the production efficiency can be effectively improved, moreover, by using laser processing, the environment can be prevented from being polluted, and thepracticability and the generalization performance are good.

[0009] In the prior art, the stereo vision method requires less calculation, but there are blank areas in the disparity map obtained in the flat area of ​​the image texture, so the calculated point cloud density is very low; the motion structure method has high universality , which includes the derivation process from sparse point cloud to dense point cloud, but the density of the obtained dense point cloud still depends on the texture complexity of the image. For images with flat texture, the obtained point cloud density is relatively low; based on depth The image reconstruction method has high precision and does not require the complexity of the image texture. However, this method is highly sensitive to the accuracy of the depth camera and is currently not suitable for 3D reconstruction of finely carved objects.

The accuracy of the 3D base CAD data obtained by the existing technology is poor
