Embodiment Construction

[0048] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description are only These are some embodiments of the present invention. Those skilled in the art can also obtain other drawings based on these drawings without creative work.

[0049] Such as figure 1 Shown, a kind of method of automatic outline extraction and path generation from bitmap of the present invention comprises the following major steps:

[0050] S1: read the bitmap file, and store the read data into the computer memory; the bitmap file includes bitmap files in BMP, JPG, PNG, TIF, and PDF formats;

[0051] S2: Determine whether the bitmap file is a color bitmap, if the bitmap file is a color bitmap, convert it into a grayscale image; thereby reducing the amo...

Abstract

The present invention discloses a method for automatic contour extraction and path generation of a bitmap. The method comprises the following steps of (1) reading the bitmap file, and storing the read data; (2) converting the bitmap file into a grey-scale map; (3) selecting a binarization algorithm to perform binarization processing; (4) performing contour extraction preprocessing; (5) performing contour extraction; and (6) obtaining cutting path generation. According to the method, the cutting path can be generated by the bitmap file without participation of professional designers or with participation of only a few professional designers, complexity of cutting path generation is reduced, generation efficiency and accuracy of the cutting path can be largely improved, cutting precision and automation degree are increased, and the method has good prospect of promotion and application.

Description

technical field [0001] The invention belongs to the field of numerical control cutting, and relates to a technology for extracting contours from bitmaps, in particular to a method for automatic contour extraction and path generation from bitmaps. Background technique [0002] At present, CNC cutting machines have been widely used in luggage, clothing, leather, bathroom, decoration, printing and advertising industries. From the perspective of cutting methods, they can be divided into two types: one is that no positioning is required before cutting, and designers directly Use CAD / CAM software to design various patterns on the computer and save them as vector files. The cutting machine control software will directly generate cutting paths from the corresponding vector files and perform cutting. This type of cutting is suitable for traditional clothing, leather, bags, paper Die, three-dimensional splicing and other application scenarios; the other is to realize the customization...
