Description

Technical Field

[0001] The present invention belongs to the technical field of model rendering, and in particular relates to an automatic rendering method and device for a 3D lightweight model. Background Art

[0002] With the continuous development of the non-standard mechanical design industry, the selection and application of purchased parts in the manufacturing industry has become more and more extensive. At present, the mainstream method of selecting purchased parts in China is to search for suitable component parameter information and 3D model files on some industrial software platforms such as CADENAS, 3DSource, and Big Engineer. Current mainstream industrial software such as CADENAS and 3DSource have the function of lightweight display of component models. The lightweight display of 3D models is an entity that only retains the external structural features of the model. The lightweight display function of 3D models can directly browse the model without downloading the model file and opening it through other modeling and design software. Compared with product annotation drawings and physical product drawings, it can more intuitively reflect the structural characteristics of components, which is convenient for designers to quickly select.

[0003] The lightweight functions of current industrial software can realize functions such as dimension measurement, cross-section viewing, and exploded views, which is convenient for users to explore the model structure in depth. However, the lightweight appearance color display still has the following defects: 1. The color of the lightweight display of parts on the current industrial software platform is based on the color when the manufacturer builds the model. Through practical investigation, the color of most industrial purchased parts models in CADENAS is gray. The monotonous color often makes it impossible to simply distinguish the contact surfaces and various features between different parts of the component, which is not conducive to users having a more realistic appearance perception of the model; 2. The lightweight display of some industrial software has a one-click coloring function, which can randomly attach several different general colors to different parts of the component, but the random coloring effect is difficult to guarantee most of the time, and the renderings still need to be re-rendered by engineers.

[0053] See also Figure 1-Figure 6 One embodiment of the present invention provides a method for automatically rendering a 3D lightweight model, comprising the following steps:

[0054] S100: Obtain a parameter table corresponding to an input 3D lightweight model, and obtain material information and surface treatment information in the parameter table.

[0055] In this embodiment, the 3D lightweight model can be uploaded by the user in real time, or it can be uploaded in batches and input at a scheduled time. When the 3D lightweight model is input, a parameter table of the 3D lightweight model is also carried, and the parameter table includes material information and surface treatment information.

[0056] In one embodiment, the obtaining of the material information and the surface treatment information in the parameter table is specifically any one of the following situations:

[0057] The parameter table includes the material information but does not include the surface treatment information;

[0058] The parameter table includes the material information and the surface treatment information;

[0059] The parameter table does not include the material information, but includes the surface treatment information;

[0060] The parameter table does not include the material information and does not include the surface treatment information.

[0061] In this embodiment, if Figure 2 and Figure 3As shown, the parameter table carried by the 3D lightweight model may contain both material information and surface treatment information, or may not contain both material information and surface information. Obviously, only one of the material information and surface information may exist, which is related to the specific situation of the 3D lightweight model.

[0062] S200: output a first recognition result based on the material information and the surface treatment information.

[0063] In this embodiment, the corresponding first recognition result is output according to whether the material information and the surface treatment information exist, such as Figure 2 As shown, the present invention can be implemented by a system for automatically rendering a 3D lightweight model based on component material and surface treatment properties, and this step can be implemented by a component material and surface treatment identification module based on a parameter table to which the model belongs.

[0064] In one embodiment, outputting a first recognition result based on the material information and the surface treatment information includes:

[0065] When the parameter table includes the material information but does not include the surface treatment information, the first recognition result is True and the material information;

[0066] When the parameter table includes the material information and the surface treatment information, the first recognition result is True and the surface treatment information;

[0067] When the parameter table does not include the material information but includes the surface treatment information, the first recognition result is True and the surface treatment information;

[0068] When the parameter table does not include the material information and does not include the surface treatment information, the first recognition result is False.

[0069] In this embodiment, Figure 2 and 3 As shown, the first recognition result consists of two parts. The first part is True or False, and the second part is material information or surface treatment information. When both the material information and the surface treatment information in the parameter table do not exist, False is output, otherwise True is output. Correspondingly, when False is output, the second part does not exist. When True is output, material information is output only when material information exists in the parameter table but surface treatment information does not exist. In the other two cases, surface treatment information is output.

[0070] S300: Match corresponding RGB information in a preset color matching library based on the first recognition result, and output a second recognition result according to the matching result of the RGB information.

[0071] In this embodiment, Figure 2 and 4 As shown, according to the first recognition result, the RGB information corresponding to the material information or the surface treatment information is matched in the preset color matching library. RGB is a color standard in the industry. Various colors are obtained by changing the three color channels of red (R), green (G), and blue (B) and superimposing them on each other. RGB represents the colors of the three channels of red, green, and blue. This standard almost includes all colors that can be perceived by human vision and is one of the most widely used color systems. Therefore, by obtaining the corresponding RGB, it can be used for subsequent automatic rendering, and the corresponding second recognition result is output after obtaining the RGB information.

[0072] In one embodiment, matching corresponding RGB information in a preset color matching library based on the first recognition result includes:

[0073] When the first recognition result is True and the material information is obtained, matching the RGB information corresponding to the material information in the preset color matching library;

[0074] When the first recognition result is True and the surface treatment information is present, matching RGB information corresponding to the surface treatment information in the preset color matching library;

[0075] When the first recognition result is False, the RGB information is not matched in the preset color matching library.

[0076] In this embodiment, Figure 4 As shown, there are three cases for the second output result, including False, True+RGB information corresponding to material information, and True+RGB information corresponding to surface treatment information. This step can be completed by matching the corresponding color processing module based on the component material and surface treatment.

[0077] In one embodiment, outputting a second recognition result according to the matching result of the RGB information includes:

[0078] When the RGB information corresponding to the material information is matched, the second recognition result is True and the RGB information corresponding to the material information;

[0079] When the RGB information corresponding to the surface treatment information is matched, the second recognition result is True and the RGB information corresponding to the surface treatment information;

[0080] When the RGB information is not matched, the second recognition result is False.

[0081] S400: Automatically render material and surface treatment properties of the 3D lightweight model based on the second recognition result.

[0082] In one embodiment, automatically rendering the material and surface treatment properties of the 3D lightweight model based on the second recognition result includes:

[0083] When the second recognition result is True and the RGB information corresponds to the material information, a color corresponding to the RGB information corresponding to the material information is selected from the preset color library to automatically render the material of the 3D lightweight model;

[0084] When the second recognition result is True and the RGB information corresponding to the surface treatment information is present, a color corresponding to the RGB information corresponding to the surface treatment information is selected from the preset color library to automatically render the surface treatment attributes of the 3D lightweight model;

[0085] When the second recognition result is False, the 3D lightweight model is not rendered.

[0086] In this embodiment, Figure 5 As shown, when the second recognition result carries RGB information corresponding to the material information, the material is automatically rendered using the RGB information, otherwise, the surface treatment properties are automatically rendered.

[0087] In one embodiment, the method further comprises:

[0088] An association table is established between the material information and the surface treatment information and the RGB information in the preset color matching library, so that the RGB information corresponding to the material information or the surface treatment information is matched from the preset color matching library through the association table.

[0089] In this embodiment, the association table can be stored in the cloud, and can be called from the cloud by the corresponding color processing module based on component material and surface treatment matching during the automatic rendering process. It can also be directly stored in the corresponding color processing module based on component material and surface treatment matching to quickly respond to the RGB information matching process. At the same time, in order to improve the automatic rendering efficiency and accuracy of the 3D lightweight model, the association table is updated in real time or periodically.
