Description

Technical Field

[0001] The present invention belongs to the field of archaeological cultural relics protection, and in particular relates to a method for generating muscle texture drawings of digital scanning models for archaeology. Background Art

[0002] In recent years, the application of digital technology in the field of archaeological cultural relics protection has enabled this field to develop rapidly, not only improving the efficiency, accuracy and depth of cultural relics protection work, but also greatly promoting the development of other industries radiating from it, such as: industry, culture, entertainment, manufacturing, handicrafts, etc.

[0003] Based on the current state of digital preservation, it is possible to scan archaeological artifacts in three dimensions, obtain primary data, and then statistically analyze, improve, and apply this raw data, achieving non-contact collection of artifact information. This data can be processed into different types, such as three-dimensional and two-dimensional data. However, there is currently a lack of methods for secondary processing of the surface texture obtained by scanning archaeological artifacts to obtain relevant data.

[0004] In order to further develop the field of digital archaeological cultural relics protection and obtain more perfect and complete cultural relics data, the rapid mapping of surface muscle texture scanning model data is Figure 2 A secondary generation method is very necessary. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for generating muscle texture mapping of a digital scanning model for archaeology, which is beneficial to improving the integrity of cultural relic data.

[0006] The technical solution adopted by the present invention is a method for generating muscle texture drawings of a digital scanned model for archaeology, comprising the following steps:

[0007] Step 1: Scan the cultural relic with a scanner to obtain the original muscle texture data of the cultural relic;

[0008] Step 2: Import the original muscle texture data of the artifact described in Step 1 into Geomagic Studio, process the redundant scan data, and import it into Rhino software to obtain a complete and accurate model drawing;

[0009] Step 3, importing the model drawing described in step 2 into Adobe Photoshop software to obtain a flat line drawing;

[0010] Step 4: introduce the secondary development method to process the plane data of the surface muscle texture layer;

[0011] Step 5: Using image recognition methods, remove noise points and rough edges on the plane view frame to obtain a digital plane view of the muscle texture;

[0012] Step 6: Process the plan views obtained in step 5 in batches with one click.

[0013] The present invention is also characterized in that:

[0014] In step 1, Geomagic Studio software processes redundant scan data into miscellaneous surfaces, broken surfaces, and noise points.

[0015] In step 2, the processing of redundant scan data is specifically to perform cutting and repairing of the model.

[0016] Step 2 specifically involves importing the 3D model data into Rhino to adjust the light and shadow to obtain a rendering effect model image.

[0017] The rendering effect model diagram includes line drawings, section views, and rendering file drawings.

[0018] Step 3 specifically involves importing the model image into Adobe Photoshop and deleting any parts that interfere with the desired artifacts.

[0019] The specific steps of the secondary development method in step 4 include:

[0020] Step 4.1, select the "Action" command in the software to create a new action;

[0021] Step 4.2. Select the "High Contrast" command in the filter bar of the menu bar. Adjust the radius parameter value in the command according to the specific situation of the model and adjust the value to 6 until the texture is clear.

[0022] Step 4.3. Use the "Filter Gallery" command in the filter bar, select the "Note Paper" sub-command of the "Sketch" layer, adjust the image balance parameter value to 25, the granularity to 0, and the relief to 0.

[0023] In step 4.4, select the "Threshold" command and adjust the threshold color level parameter to 180 to generate a flat view with rich and clear colors.

[0024] In step 4.5, use the "Selection" tool to cut half of the complete muscle texture view obtained in step 5.4 with the sagittal plane as the symmetry plane, to obtain a half view of the muscle texture that can be combined with the line drawing and cross-sectional view of the overall model.

[0025] The beneficial effects of the present invention are:

[0026] The method for generating muscle texture drawings of digital scanning models for archaeology of the present invention obtains a three-dimensional model by processing the original data obtained by three-dimensional scanning, and outputs it as a two-dimensional plane map for a second time. The obtained surface muscle texture layer is added to the overall two-dimensional plane map of the cultural relic, thereby achieving a digital two-dimensional plane map of the archaeological cultural relic with four effects of lines, cross-sections, textures and colors, thereby improving the integrity of the scanned data.

[0028] Figure 2 It is a schematic diagram of a specific implementation method of the method for generating muscle texture mapping of a digital scanning model for archaeology according to the present invention. DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 and Figure 2 As shown, the method for generating muscle texture mapping of a digital scanning model for archaeology of the present invention is specifically implemented according to the following steps:

[0031] Step 1: Scan the cultural relic with a scanner to obtain the original muscle texture data of the cultural relic. Import the original model obtained by the 3D scanning instrument into Geomagic Studio software to process the redundant scanning data. After cutting and repairing the model, the model of the surface muscle texture layer can be obtained.

[0032] In step 1, Geomagic Studio software processes redundant scan data into miscellaneous surfaces, broken surfaces, and noise points.

[0033] Step 2: Import the model obtained above into Rhino software, adjust the light and shadow to obtain a clear and complete rendering effect model image, select the "Rendering Effect" view to save the image at a fixed scale, and then flatten the texture lines.

[0034] The rendering effect model diagram includes line drawings, section views, and rendering file drawings.

[0035] Step 3. Import the rendered file obtained in step 2 into Adobe Photoshop software. First, use the "selection" tool to reverse select the redundant areas in the view and delete the parts in the view layer that interfere with the required artifacts.

[0036] The purpose of importing the rendered file into Adobe Photoshop is to convert the surface texture of the "Rendering Effect" view into a flat line drawing.

[0037] Step 4: Introduce the secondary development method, select the "Action" command in the software, and create a new action. The specific steps are as follows:

[0038] 1) Then select the "High Contrast Preservation" command in the filter bar of the menu bar, debug the radius parameter value in the command according to the specific situation of the model, and adjust the value to 6 until the texture is clear.

[0039] 2) Again use the "Filter Gallery" command in the filter bar, select the "Note Paper" sub-command of the "Sketch" layer, adjust the parameter value of Image Balance to 25, the Graininess to 0, and the Emphasis to 0. This can make the lines of the muscle texture clearer and more separated.

[0040] 3) For special organ types with color textures, use the adjustment bar of the image bar, select the "Threshold" command, and adjust the threshold color level parameter to 180. The purpose of deepening the threshold is to darken the hue of the separated muscle texture lines mentioned above, generating a plane view with richer and clearer colors.

[0041] Step 5. Use the "Selection" tool and, based on the artifact drawing method, use the sagittal plane as the symmetry plane to cut half of the complete muscle texture view, thus obtaining a half-view of the muscle texture that can be combined with the line drawing and cross-sectional view of the overall model.

[0042] Step 6: Use image recognition methods to erase noise points, burrs, etc. on the plane view border, and finally obtain a smooth and clear muscle texture digitized plane view.

[0043] Step 7. Select the Automatic column in the File column, use the "Batch Processing" command, select the "New Action" created in the above step 4 in the Action column, and choose to import the plan view obtained in the above step 6 for one-click batch processing.

[0044] The present invention is based on an archaeological cultural relic data acquisition platform. Through digital acquisition technology, the collected digitized archaeological cultural relic original data is subjected to secondary mapping processing. The focus is on obtaining highly accurate surface texture processing data of cultural relics, improving the integrity of cultural relic data, and achieving a step-by-step promotion effect in the digital protection and restoration of archaeological cultural relics.
