Description

Three-dimensional modeling software three-dimensional inspection model unstructured data analysis method
Technical Field
The invention relates to a visual unstructured three-dimensional model data analysis method for analyzing unstructured data (unstructured data) of a three-dimensional inspection model of three-dimensional modeling software into a computer understandable format.
Background
The data in the world is growing in an explosive situation, wherein the content of unstructured data occupies 80% of the current data sea, and more than 80% of the data can be unstructured data with greater processing difficulty, the exponentially growing data volume makes it almost impossible to use manual work to complete the data management process, and computers become important tools for data management, however, most computer software can only understand certain data with specific structures according to preset programs, so that computers do not seem to be distracting when managing unstructured data.
The unstructured data is more easily represented by the unstructured data in a more general structured data system than the structured data in a more general structured data system, the unstructured data is more easily represented by the structured data in a more general structured data system than the structured data in a more general structured data system, the structured data is more easily represented by the structured data in a more general structured data system than the structured data in a more general structured data system, the structured data in a more general structured data, the more difficult structured data in a more general structured data, more difficult structured data, more information.
One difficulty with unstructured data storage is that the content of metadata to be extracted cannot be determined in advance, and the content and format of the metadata may change as the system requirements change. In fact, pure unstructured data is not present. Firstly, the unstructured data may contain partially structured information and many different types of features, wherein the unstructured data may contain data with format information, such as tables; secondly, the unstructured data can be converted into structured data under the translation of a proper interpreter, and structured meta information such as a data storage mode, a data producer, a data transmission mode and even data can be extracted from the unstructured data. Relational databases the files used to store data, which are unstructured before database management loads and parses, are typically binary files stored on disk. The method has the defects that the structure is complex, the implementation difficulty is increased, in addition, the machine can automatically mine and understand the structured part in the unstructured data through means of machine learning, natural language processing and the like, and the structure of the data is learned according to the method. The data generally has two storage modes, the first mode is to store the data in a file system and store a file link in a database, and the mode has certain safety problem and needs extra work to ensure the ACID characteristic of a transaction; the other mode is that large data types provided by a database system are used for storage, such as Blob of Oracle, the mode increases IO work in the database query process, and therefore efficiency is low, some database systems provide a columnar storage model to solve the problem, metadata is used as the feature of unstructured data, and compared with original data, the metadata has certain structurality, and the feature can be described by using a feature type and a feature value binary group, so that a corresponding relation exists between the metadata and an entity of a relational data model. Second, the complexity of unstructured data determines the versatility of its metadata type, and even unstructured data of similar types may exist in disparate metadata types. Due to the diversity of unstructured data, the whole entity relationship model is abnormally bloated, and therefore the complexity of a data management program is increased. One difficulty with unstructured data storage is that the content of metadata to be extracted cannot be determined in advance, and the content and format of the metadata may change as the system requirements change. Over time and with the increasing number of users, the original data scheme is gradually faced with some problems: the application system is frequently changed, so that new and old data are difficult to be compatible; the system needs to process a large amount of unstructured data, and the management requirement is variable; the data volume is larger and larger, the original copying technology not only wastes the storage space, but also can not improve the execution efficiency of single complex query operation. If the structure is complicated, the difficulty of implementation is increased.
In a modern manufacturing enterprise, process data is the most important and basic technical data for the transformation of the process data of the enterprise. For a long time, due to the lack of professional auxiliary software support, in the information society, the data types of information are mainly three types: the traditional process is mostly manually compiled by office software, and the process data mostly exist in an independent electronic document form. With the lapse of time, process data accumulate day by day, the data volume is huge, and is dispersedly stored in an unstructured data form, the process data sharing and the reusability are poor, the knowledge contained in the data resources cannot be fully mined and utilized, and the problems of abundant data and poor knowledge are very serious. The traditional process rule usually relies on WORD software to create a one-dimensional table and describe process information in the form of the one-dimensional table, and belongs to a typical unstructured data type.
With the rapid development of information technology, the method and means for designing products in the mechanical industry undergo the leap-type development from manual drawing to two-dimensional CAD technology and then to three-dimensional modeling technology, the transformation from planar projection technology to full three-dimensional model digital prototype and complete digital product definition is realized, and the analysis and verification of product performance and manufacturing capability are finished by relying on a computer application system more and more. The three-dimensional labeling technology really opens the full three-dimensional digital design and manufacturing era, really realizes the three-dimensional digital and drawing-free design and manufacturing technology, enables the two-dimensional engineering drawing or the engineering drawing to become history, is no longer the manufacturing authority basis even if the two-dimensional engineering drawing or the engineering drawing exists, and is only an auxiliary expression mode of data under specific conditions. However, although the product design process has all the engineering and manufacturing information contained in the three-dimensional model, when the data of the three-dimensional model is transmitted to the product manufacturing process, the data is stored in an unstructured mode, and only special tool software, such as typical unstructured three-dimensional modeling software CATIA, UG and the like, can be used for analyzing and extracting the data for being identified or applied by a relevant technician or an information system. These software relational databases are unstructured before the files used to store the data, which are typically binary files stored on disk, are loaded and parsed by the database management. Metadata is used as the characteristics of unstructured data, and the characteristics are divided into basic attributes, semantic characteristics, bottom-layer characteristics and original data to represent the data into dimensions, variables, attributes and original data. However, the metadata of unstructured data is not necessarily able to simply correspond. First, the data type of metadata is not necessarily an atomic type, and may be a list or even unstructured data, so the actual corresponding result is a tree structure. The complexity of unstructured data determines the versatility of its metadata types, even though unstructured data of similar types may exist in disparate metadata types. The complexity of unstructured data makes it often inadequate to utilize views alone, and database management systems typically do not support update operations across table views. With the increase of time and user quantity, the original data scheme gradually faces some problems that an application system is frequently changed, so that new and old data are difficult to be compatible; the system needs to process a large amount of unstructured data, such as logs and images, and the management requirements are variable; the data volume is larger and larger, the original copying technology not only wastes the storage space, but also can not improve the execution efficiency of single complex query operation. The unstructured data structure is complex, the realization difficulty is high, and the problem of management and data version compatibility is difficult to solve.
The three-dimensional modeling software CATIA adopts a characteristic modeling and parametric modeling technology, has a unified user interface, data management and compatible database and application program interfaces, can watch the model from any direction, is easier to visually inspect the structure of a part and interfere among the parts, and greatly depends on the conformity of dimensional constraints in a two-dimensional graph and physical parameters.
