Embodiment Construction

[0011] The present invention provides a mold CAD drawing query and management system based on similarity query. The implementation process of the system is as follows: figure 1 shown, including:

[0012] (1) Drawings are stored in batches. The company has accumulated a large number of drawings. The basic information of these drawings is extracted and entered into the database in batches for unified management and query. These basic information mainly include: designer, design time, purpose, graphic features of drawings, etc. The graphic feature of the drawing is the key information for similarity query.

[0013] (2) Drawing query based on similarity, users can use various query methods to query drawings in the database, for example: query through CAD drawings, query through simple drawings, or query through photos.

[0014] (3) The similarity is a positive real number (0%-100%), which can be input by the user according to the needs. According to the similarity, the system wi...

Abstract

The invention discloses a mould CAD drawing query based on similarity query and a management method, according to the following steps: putting the drawing in storage in a batch mode, extracting the basic information of the CAD drawing and writing the basic information into the database in a batch mode; extracting the geometry moment of the section of the mould as the shaft characteristic; extracting the basic element characteristic of the midpoint, line and surface and the like of the drawing; taking the extracted characteristic as the similarity calculating parameter, defining the similarity percentage according to the requirement and contrasting the shape characteristic of different drawings, calculating the similarity of the different drawings according to the mathematic operation, thereby obtaining the final search result. The mould CAD drawing query based on similarity query and the management method are simple in method and high in query precision.

Description

technical field [0001] The invention belongs to the technical field of drawing classification query management, and relates to a method for querying and managing mold CAD drawings based on similarity query. Background technique [0002] Mold is the key equipment for forming various materials or products. Over time, many manufacturers have accumulated a large number of mold design drawings. On the other hand, mold designers often need to refer to historical mold drawings when developing new molds. Therefore, mold drawing management software systems came into being. Currently known mold drawing management software systems basically manage and query drawings based on keywords, such keywords include time, designer, purpose, and so on. The current query method is too complicated, the query precision is low, and it cannot be quickly and effectively searched. The invention adopts the similarity degree to manage and query drawings, which can conveniently and quickly help mold desi...
