Laser cutting system based on image recognition

Abstract

The invention provides a laser cutting system based on image recognition. The system comprises an image acquisition module, an image processing module, a path planning module, a coordinate calculationmodule, a laser cutting unit and a main control unit, wherein the image acquisition module comprises a first camera and a second camera, and the first camera is used for acquiring the integral graphof the graph to be cut; the image processing module is connected with the image acquisition module; the path planning module is connected with the image processing module and is used for dividing thewhole graph acquired by the first camera into a plurality of unit patterns, acquiring the position of each unit pattern and planning the cutting sequence of each unit pattern to acquire the shortest cutting path, and the second camera is used for acquiring the local graph of each unit pattern; the coordinate calculation module is used for calculating coordinate information of the local graphs shotby the second camera after being processed by the image processing module; and the laser cutting unit comprises a laser head and a numerical control objective table. With the system, when multi-target cutting is required for complicated patterns, an optimal cutting path can be obtained, and the required patterns can be obtained through cutting more accurately.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser cutting system based on image recognition. Background technique [0002] Although the existing laser cutting control systems on the market can cut various materials, most of them are limited to cutting according to the graphic files derived from the computer. However, in the market, sometimes there are various good-looking printing patterns, but the general CNC cutting system cannot immediately use the computer to generate graphics files in time. [0003] In the field of computer vision, the research history of extracting target contours from source images is not long. People have gradually discovered its important value, and have gradually paid attention to and studied it. Some CNC cutting systems are combined with computer vision technology to recognize graphics, but for complex graphics, for example, there are N patterns in the graphics, it is difficult for s...
