Problems solved by technology

When the traditional scheme uses image processing software to generate DXF curves, the center line of the image is extracted based on vectorization, and the image skeleton is obtained by "corroding" the graphic boundary to the center according to the Voronoi diagram principle. This method relies heavily on the quality of the image, and the image is blurred The skeleton line obtained during the process is not smooth enough, and it is prone to line loss, which cannot meet the high ornamental requirements of handicrafts
The traditional technical solution requires the operator to switch between multiple softwares, the time utilization rate is low, and the requirements for the operator are high

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] see figure 1 , the present invention is based on the curve engraving path generation method of point string fitting and comprises the following steps:

[0028] 1. Obtain input point strings through the digital board to construct engraving curve graphics. Personalized input devices such as digital boards can be used to directly obtain two-dimensional point string data such as electronic signatures, and then construct engraving graphics.

[0029] 2. Process point string data to generate smooth engraving curve graphics.

[0030] 1) Convert the point string data screen coordinates to physical coordinates through coordinate conversion.

[0031] The coordinates of the data points obtained through a personalized input device such as a digital tablet are screen coordinates. The Y axis of the screen coordinate system is opposite to the Y axis of the physical...

Abstract

The invention discloses a curve engraving path generation method based on point-string fitting. The curve engraving path generation method comprises the steps of: 1) constructing an engraving curve pattern by acquiring two-dimensional input point-string data; 2) carrying out denoising processing on the point-string data and re-performing spline fitting to generate a smooth engraving curve pattern; 3) carrying out the following processing to generate a machining pattern: 3.1) centralizing the smooth engraving curve pattern so that the engraving curve pattern coincides with the center of an engraving region coordinate system, 3.2) zooming the engraving curve pattern so that the engraving curve pattern fills up an engraving region maximally, 3.3) and positioning the engraving curve pattern, maintaining an original shape of the engraving curve pattern, and positioning the engraving curve pattern to a designated region; 4) and generating a corresponding CAD or CAM template according to the machining pattern. The curve engraving path generation method adopts the idea of a template, formulates different rules according to different machining requirements, generates corresponding templates, simplifies subsequent manual operations and improves the efficiency.

Description

technical field [0001] The invention relates to the field of personalized handicraft processing, in particular to a method for generating curve engraving paths based on point string fitting. Background technique [0002] Incorporating personalized elements into handicrafts has gradually become a model that consumers prefer, such as engraving personal handwritten signatures on handicrafts. The engraving processing of this personalized element mainly adopts image processing technology and numerical control processing technology. Image processing software mainly converts personalized elements into curve data required for processing, while NC processing mainly uses CAD / CAM software to generate processing paths. Currently commonly used image processing software includes PhotoShop, 3DMax, Rhino software, etc. The mainstream CAD / CAM software includes French Catia, German Siemens NX, etc. [0003] The traditional personalized handicraft processing scheme first obtains the signatur...
