System and method for checking small line segment figure

Abstract

The invention relates to a system for checking a small line segment figure, comprising a parameter setting module, a figure selection module, a figure element dividing module, a figure element detection module and a figure element identification module, wherein the parameter setting module is used for setting the allowable value of the length of a small line segment; the figure selection module is used for reading figure parts from a figure library and determining a figure element needed to be checked in the figure parts, and the figure element comprises a line, a line segment and a circular arc; the figure element dividing module is used for classifying the figure elements, dividing the line into the line segment and the circular arc and merging the divided line segment and the divided circular arc into a figure checking area; the figure element detection module is used for calculating the length of the line segment and the perimeter of the circular arc and judging whether the length of the line segment and the perimeter of the circular arc are smaller than the allowable value or not; and the figure element identification module is used for identifying the small line segment figure which does not conform to a processing standard by an instruction sign and displaying the position of the small line segment figure in the figure parts in a display device. The invention also provides a method for checking the small line segment figure. The invention can detect whether the figure parts meet the processing standard to enhance the quality of the figure parts.

Description

technical field [0001] The invention relates to a graphic inspection system and method, in particular to a small line segment graphic inspection system and method. Background technique [0002] In graphics processing, a small line segment is a general concept, and there is no exact regulation on the specific data range, but generally speaking, a line segment, arc, 1 / 4 arc and other graphics elements with a length of less than 0.1mm can be called small line segment. figure 1 (a)-(c) are simple examples of small line segments in a part drawing. figure 1 (a) is the original image of a small line segment, figure 1 (b) is the right end of the small line segment enlarged by ten times, figure 1 (c) is the obvious sharp corner that appears after the small line segment is magnified one hundred times. From figure 1 In , it can be found that the original visual effect is a small line segment that is a straight line, but after zooming in, a sharp-edged figure appears on the right e...

Problems solved by technology

If there is a problem during the processing, not only the processing materials and time are wasted, but also the waste of the electrode wire is a considerable expense, so it is necessary to ensure the correctness of the processing path as much as possible before the parts are processed, that is, to detect the processing Whether there are unprocessable parts in the graphics, to prompt the processor to deal with such graphics

[0004] However, at present, the naked eye is generally used to detect the processed graphics, but the naked eye cannot detect all small line segment graphics smaller than the specified range, so it cannot guarantee whether the processed graphics meet the processing conditions, resulting in losses caused by problems during the processing
