Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0052] Example.

[0053] see Figure 1 to Figure 2 , the variable cutting trajectory generation method of the borderless image in this embodiment, the steps are as follows:

[0054] (S1) Establish cutting prior knowledge

[0055] 1) Obtain the base image.

[0056] 2) Make basic image templates, make k basic image blocks with unique characteristics as the basic image template set Match: {matchContour1, matchContour2, ..., matchContourk}, k≥1, each matchContouri represents a unique necessary feature base image blocks.

[0057] 3) Establish the basic feature vector trajectory set BasicContour corresponding to the basic image template set Match. The elements of BasicContour can be rectangles or directly the vector d...

Abstract

The invention relates to a variable cutting track generation method for a boundless image, and belongs to the field of automatic cutting. A basic image is obtained through an image obtaining device; acorresponding relationship between the basic image and the cutting track is built and stored as priori knowledge in a knowledge base; prior knowledge is selected from a knowledge base; in the printing material cutting production process, the selected feature template is used for matching collected images to obtain the position of a basic image, and then the corresponding position of a cutting track on a cutting bed is automatically generated through cutting bed coordinate transformation, data grouping after transformation, cutting track position relation trace mapping matching and other processing. According to the invention, automatic generation of the cutting track for automatic alignment of the periodic printing materials with different cutting requirements can be achieved for the samecutting material, and the problems that the cutting track of the printing material without an obvious cutting track is difficult to extract, and the flexible and changeable cutting requirements are difficult to meet are solved.

Description

technical field [0001] The invention relates to a method, in particular to a method for generating a variable cutting trajectory of a borderless image, which is a method for automatically generating a cutting trajectory of a periodic printing material without an obvious boundary trajectory, and belongs to the field of automatic cutting. Background technique [0002] Printing materials in the cutting industry have rich patterns and colors, different shapes, and the cutting needs are ever-changing. Using machine vision technology to realize the automatic generation of cutting trajectory enables customers to easily use intelligent cutting equipment to realize automatic production and significantly improve the production efficiency of products. [0003] The current method needs to outline the cutting track of the printing material with a prominent color, and the color difference between the cutting track and the background color is obvious. Secondly, it is necessary to increase ...
