Abstract

Disclosed herein are a method of representing an environment object in a cyber-physical system using an environment data model structure and a computer-readable storage medium storing a program therefor. A library model for storing information required to visualize environment data as an environment object in a cyber-physical system is generated. A geometry representation model having geometry structure information of the environment data is generated. A feature representation model having two-dimensional (2D) or three-dimensional (3D) information of the environment data is generated. A model structure of the environment data including the library model, the geometry representation model, and the feature representation model is configured. An environment data file having information about the model structure of the environment data is stored in a database (DB). The environment object in the cyber-physical system is visually represented using the environment data file stored in the DB.

Claims

1. A method of representing an environment object in a cyber-physical system using an environment data model structure, comprising:

generating a library model for storing information required to visualize environment data as an environment object in a cyber-physical system;

generating a geometry representation model having geometry structure information of the environment data;

generating a feature representation model having two-dimensional (2D) or three-dimensional (3D) information of the environment data;

configuring a model structure of the environment data including the library model, the geometry representation model, and the feature representation model;

storing an environment data file having information about the model structure of the environment data in a database (DB); and

visually representing the environment object in the cyber-physical system using the environment data file stored in the DB.

2. The method of claim 1, wherein generating the geometry representation model comprises generating a geometry model instance indicative of a model instance having geometry structure information of the environment data.

3. The method of claim 2, wherein the geometry model instance is represented by at least three polygon instances.

4. The method of claim 2, wherein generating the geometry representation model further comprises:

generating a reference model indicative of a reference relation between geometry model instances;

generating an identification model having identification information of the geometry model instances; and

generating a data table representing geometry structure information of the environment data in a format of a table.

5. The method of claim 4, wherein the data table is a table in which one or more of a property value, a property table, behavior, and transformation information related to a geometry structure of the environment data are represented in a format of a table.

6. The method of claim 1, wherein generating the feature representation model comprises generating a feature model instance indicative of a model instance having 2D or 3D information of the environment data.

7. The method of claim 6, wherein the feature model instance is defined by point features, linear features, areal features, or volume features.

8. The method of claim 6, wherein generating the feature representation model further comprises:

generating a reference model indicative of a reference relation between feature model instances;

generating an identification model having identification information of the feature model instances; and

generating a data table representing 2D or 3D information of the environment data in a format of a table.

9. The method of claim 8, wherein the data table is a table in which one or more of a property value, a property table, behavior, and transformation information related to 2D or 3D features of the environment data are represented in a format of a table.

10. A computer-readable storage medium storing a program for executing the method as set forth in claim 1.
