Scanning Procedure

Preparation

  1. Observe the scanned objects: objects, creatures, size, color, material, deformation, etc;

  2. Observe the scanning environment: dark, bright, narrow, dangerous, etc; 1

  3. Quick Calibration first；

  4. Click Scan, enter the scan interface

  5. Select or create a new scanning mode. By default, there are 3 modes: Human Body Scanning Mode, Colorful Object Scanning Mode and LED Off Mode; 2

  6. Set Resolution

  7. The scanner is connected. If it is not, please check the diagnosis.

How to turn off scan preview

  1. Click the button on the scanner to enter the preview state where you can observe the software interface will appear as some “shadow” that is the scanner capturing some 3D point cloud data ( point cloud ). It can help check whether the scanned object is easy to be scanned and whether the distance is appropriate through the point cloud sparse degree.

  • The reason for the sparse dot cloud may be: too close, or too far, you can observe the distance bar on the right to determine; whether the swept object is too bright, or too dark, too small, too transparent, you can spray developer to enhance.

  • The impact of too sparse point clouds: If you choose the ‘feature splicing’, situation like splicing failure, splicing errors, splicing non-fluency would occur.

  • 09:13If you get good at scanning and don’t like to preview every time, the preview function can be turned off in Settings as shown in the right figure.

  1. Click the button on the scanner again to pause the preview, click again to officially start scanning, and complete the scan according to some scanning tips and scanning techniques.

Hint

When using the marker splicing, the process is different from the normal process. For details, see Marker Splicing .

After Scanning

  1. When the scan is complete and no other operations are needed, you can either save the project as a scan in the menu bar so that you can continue scanning next time, or you can click the Finish button A to perform a point cloud calculation, before which you can select a different resolution in the drop-down box on the right B and then perform the point cloud calculation. After selecting the resolution, click the Data Quality Color Map button.

  1. Point cloud prot-processing

Enter the point cloud processing interface after the calculation is completed: the upper toolbar can be done to remove isolated points E, non-connected items F and other operations, click the drop-down box next to the meshing B, select the way to fill the hole, whether to optimize the mesh, whether to simplify the mesh (recommended use), whether to mark points to fill the hole, whether to fill a small hole and then generate the mesh C.

  1. In the Mesh interface:

Mesh processing: the upper toolbar can do mesh simplification G, mesh refinement and other operations H, click the drop-down box next to the map I, select whether to map smoothing and then generate a map.

  1. In the Texture interface:

Texture processing: The upper toolbar can adjust the hue, luminance, saturation, ambient, and specula.

Hint

3 ways to fill holes

  • Not Close Holes: No hole filling, fast speed, suitable for importing the third software for processing

  • Close Small Holes: In the Human Scene, the model will have the edge extension but not in the Object Scene. Most of the holes will be filled.

  • Fully Close Holes: All holes will be filled. If some holes are too big, it will be ugly to use this function. The algorithm cannot achieve the hole-filling effect we imagined.

Saving Projects & Files

Based on the scanning procedure, we have 4 different projects, each of which represents a data type and an interface, respectively:

Data Type

Interface

Data Type To Be Saved

Original Scanned Data

Scan Interface

Scan Project (.epj)

Point Cloud Data

Point Cloud Interface

Point Cloud Project (.apj), Point Cloud file (.asc)

Mesh Data

Mesh Interface

Mesh Project (.spj), Mesh File (.stl/.sk/.obj (monochrome model) /.ply)

Mesh data with texture

Texture Interface

Mesh File (.stl/.sk/.obj (colorful object) /.ply)

Error

Please do not use the Chinese name when saving an .obj files. Some third-party software may not support it, which may fail the maps to link automatically. At this time, we need to manually change some details in .mtl and .obj.

Various scanned objects and scanning environments require different operation methods or techniques to help us scan better. Please check for details.
