Computer-aided design (CAD) graph and image mixed editing system

Abstract

The invention discloses a computer-aided design (CAD) graph and image mixed editing system, which comprises an expression and storage module, a primitive acquisition module, a first selection module, a second selection module, a first image editing module, a second image editing module, a primitive fusion module and a uniform primitive editing module, wherein the expression and storage module is used for uniformly expressing graphs and images through a uniform bottom abstract type and storing the graphs and the images in a storage medium; the primitive acquisition module is used for inputting graph elements by a user, acquiring the graph elements and image elements and displaying the graph elements and the image elements in a view in a mixed mode; the primitive acquisition module comprises a graph opening sub-module, an image inserting sub-module and a clipboard operating sub-module; and the graph opening sub-module is used for opening graph and image mixed format files completed in previous work of the user. Through the system, the graphs and the images can be fused together by a designer and used as a uniform model for editing.

Description

technical field [0001] The invention belongs to the field of graphics and image processing, and more specifically relates to a CAD graphics and image mixed editing system. Background technique [0002] In the process design process of the manufacturing industry, the design department generally provides design drawings. These drawings are usually CAD graphics files. Based on this, the process designer designs relevant process information, such as fixture symbol labeling, process dimension labeling, Graphics modification, etc. These functional requirements lead to the need to have the ability to edit CAD graphics in the process of process design. On the other hand, in the process design of painting, assembly, welding, etc., designers need to be able to use image symbols and physical electronic photos. Describe the steps of the process visually. These images need to perform a series of image processing operations such as zooming, transparency, highlighting, rotation, shearing, ...

AI Technical Summary

Problems solved by technology

[0003] Although there are many professional processing software in the field of image processing, these systems cannot be integrated into CAD graphics processing, and can only edit images in isolation, which cannot meet the actual needs of CAD graphics and image fusion

[0004] In terms of graphics processing software, there are many professional CAD software. These software can handle graphics editing well, but they cannot provide unified expression and editing capabilities of graphics and images, and cannot achieve mutual integration of graphics and images.

[0005] Based on the respective limitations of existing software, in the manufacturing industry, especially in the automobile assembly industry, designers can only process CAD graphics first, then convert them into images, and then perform some process identification in image processing software, and finally provide them to The downstream department is only an image, which loses the precise expression and measurement capabilities of the graphic, and cannot realize the re-modification function, resulting in a large number of repeated designs, prolonging the design time, and still unable to meet the needs of precise graphic expression
