Problems solved by technology

However, the materials used in these embroideries or woven labels and some labels are relatively soft materials, such as cloth and leather. In the process of weaving and embroidery, due to the certain elasticity of the material, the patterns woven and embroidered There is a certain amount of deformation, resulting in a certain difference in the individual patterns on the material
Therefore, according to the above cutting method, the cutting accuracy is not high, and there is a certain deviation between the cutting line and the actual outline of the cut pattern, resulting in a large number of cutting waste products

Embodiment Construction

[0016] In the laser cutting machine of the present invention, when it is commissioned at the factory or is working for the first time, it is necessary to calibrate the camera on the laser cutting machine through the software of the computer to generate a correction file, which is stored in the computer; The camera on the laser cutting machine collects the pattern on the material to be cut, and sends it to the computer through the signal line, and the computer corrects the collected image with the correction file generated above; By adjusting the RGB of the real-time captured image, the boundary of the image is made clearer, and the sense of layering of colors with similar gray levels is more obvious. Replace the rectified image with a grayscale image, and then adjust its threshold to make the boundary of the image more distinct, convert the obtained grayscale image into a contour graphic through vectorization, and adjust the smoothing parameters and connectivity parameters to m...

Abstract

The invention discloses an edge finding cutting method of a laser cutting device which is characterized in that images of an object needing to be cut are collected through a camera. A correcting document is used for the correction to generate a contour graph. Then, based on the contour graph, a matching model is constructed. Then, the patterns cut in real time are collected through the camera according to set parameters. The vectorization treatment is implemented on the collected images to generate graphs. The graphs are compared with the matching model according to the set similarity. An image satisfying the set similarity is the successful matching image. To the successful matching image, cutting data are generated according to the contour graph of the actually paragraphed image. Finally, the cutting data are sent to the laser cutting device to be cut. The cutting method is characterized by automatically adapting to the cut image differences within certain similarity scope and realizing the precise cutting of images.

Description

technical field [0001] The invention relates to a method for cutting materials by a laser cutting machine. Background technique [0002] At present, embroidery or woven labels and some labels must be embroidered or drawn on materials first. Because the laser cutting machine has the characteristics of fast cutting, it is cut one by one by the laser cutting machine. Now, the most commonly used cutting method is to install a camera on the laser cutting machine, collect the image to be cut into the computer through the camera, and the software in the computer builds a model for the collected image. The process of building a model is Generate contour lines from the collected images, and then search for matching images according to the established model contours. As long as the matching degree reaches a certain level, the established model contour parameters are sent to the laser cutting machine for cutting. This model contour There are two matching methods, one is to match the ...
