Problems solved by technology

[0004] Although computer-aided design can be realized with the help of drawing software, manual drawing is still required. Even if the information of the outline of the master is obtained by scanning directly with a scanner, it is necessary to manually remove noise, find some special point information, or repair some defects of the outline.
At the same time, the typesetting and nesting process of the layout engineer is a time-consuming and laborious process, and the automation of this design process is low

Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described below with reference to the accompanying drawings.

[0031] Such as figure 1 As shown, a shoe sample automatic nesting processing method, the processing method includes the following specific implementation steps:

[0032] Step 1: Obtain a shoe sample image, take an image containing the shoe sample to be detected and a reference rectangle, where the size of the reference rectangle is known;

[0033] Step 2: image preprocessing, input the obtained image, and then denoise the image;

[0034] Step 3: Detect and obtain the contour information, use the adaptive threshold method to obtain the binary image, and then use the canny operator to detect all the contours of the binary image, and search for the reference rectangular contour and the target shoe shape contour according to the rectangularity and contour area ;

[0035] Step 4: Calculate the scale, and calculate the scale of the sh...

Abstract

The invention discloses an automatic shoe sample discharging processing system. The processing system includes the following specific implementation steps: acquiring shoe sample images, image preprocessing, detecting and acquiring contour information, calculating scale, smoothing processing, searching for special points, and outputting single Complete graphics processing G code, layout, path optimization and complete G code after output typesetting to complete automatic layout of shoe samples. The present invention has designed a system that integrates the functions of shoe sample outline recognition, layout and G code generation. This system can eliminate the need to use drawing software for drawing or contour processing, and the process of layout by the layout engineer, and directly generates CNC processing. The production of G-code reduces the production design cycle, improves efficiency, and improves material utilization and reduces production costs.

Description

technical field [0001] The invention relates to the field of shoe material production technology, more specifically to a shoe sample automatic discharge processing method. Background technique [0002] China is a big country in the shoe industry, and its shoe production accounts for a large part of the global shoe production. However, compared with developed countries, its production is less mechanized and automated, and its production efficiency is lower. With the rise of labor costs and the increase in raw material prices, shoe production needs to develop in the direction of automation and intelligence. [0003] In shoe production, improving the automation of processing can significantly improve labor intensity and production efficiency, and improving the utilization of materials can effectively reduce the cost of shoemaking. The application and development of machine vision and computer graphics technology in this field can effectively promote processing degree of intell...
