A:

After scanning the markers, click Finish in the software or long press the button on the touchscreen and wait for the green progress circle to complete one full rotation. Release your finger when it turns into a green  (as shown in the image on the right) to finish scanning markers. Then click Start to scan the object.

 

Q:
After installing the software, when starting it, a prompt appears stating **the reason for the missing 'nvml.dll' file**
A:
  • First, check if the computer meets the requirements of NVIDIA dedicated graphics card

Task Manager - Performance -GPU (Generally, dedicated graphics cards are GPU1, so check GPU1 first. If there is no GPU1, then look at GPU0).

  • If there is no NVIDIA dedicated graphics card, the computer configuration needs to be changed. The recommended configuration is as follows:

Under the condition of having a NVIDIA independent graphics card that meets the requirements, the reasons for the absence of the dll file are as follows:

① The driver was not installed or updated correctly. ② The operating system files were damaged. ③ The system files were lost due to virus or malicious software attacks. ④ The user manually or through certain cleaning software mistakenly deleted the key system files.

The nvml.dll file needs to be installed manually or imported.

Q:
How to Use the Marker First Mode?
A:

- Mode Principle: This mode uses an infrared speckle light source and combines feature points with marker points to achieve stitching, effectively improving scanning stability in environments with insufficient features.

- Stitching Requirements: The scanner must recognize at least 1 marker point in each frame to maintain normal stitching. If stitching is lost, the scanner needs to see at least 2 marker points simultaneously to relocate and restore stitching.

- Marker Placement: Avoid placing two marker points on flat, featureless areas at the same time. It is recommended to place at least one marker point on a feature with distinct curvature or corners.

- Example Application: Infant Head Scanning

This mode is particularly suitable for scanning moving subjects, such as infant heads. Using assisted marker points can effectively counteract stitching loss caused by head movements, making the scanning process smoother. It is also recommended to enable the "Small Scanning Area" mode to limit the scanning range to the head area, avoiding capturing movements below the neck and further ensuring data quality.

Q:
In the 3DeVOK software, when aiming the scanner at an object, no point cloud is generated. The laser lines appear very weak, yet the device functions normally and calibration has been performed. What is the cause and how can it be resolved?
A:

This issue is typically caused by the surface material or color of the scanned object. Black, dark-colored, or highly reflective objects (such as metal or mirrors) absorb or reflect the laser abnormally, causing the laser lines to appear weak or difficult for the camera to recognize, thus preventing point cloud generation.

 

Solutions:

 

Increase laser brightness: Appropriately raise the laser intensity or gain in the software to enhance the visibility of the laser lines.

Use a developing agent (scanning spray): Evenly spray a developing agent (such as matte developing spray, talcum powder, or dedicated scanning spray) onto the object's surface. This will significantly improve laser reflection. Be careful not to apply too thick a coating, as it may obscure fine details.

If the above methods do not work, check whether the scanning environment has strong ambient light interference (e.g., sunlight, intense lighting). Try scanning in a darker environment.

Note: The developing agent is a temporary coating. After scanning, it can usually be removed with a soft cloth or water (refer to the product instructions for details).

 

Q:
When scanning with the 3DeVOK software, data layering errors (such as interlayer misalignment or displacement) occur. How should this be handled?
A:

You may choose one of the following two options depending on the data condition:

 

Option 1: Retract Frame (suitable for minor layering errors discovered during real-time scanning)

 

In the scanning interface, click the "Retract Frame" button, select the number of frames to retract, and undo the current frame data that caused the layering error.

 

Note: The retraction operation is irreversible. Retracted data cannot be restored. Please confirm that the frame data is no longer needed before proceeding.

 

Option 2: Point Cloud Pre-Processing Repair (suitable for overall repair after scanning is completed)

 

Click the "Finish Scan" button in the interface to end the current scan, then locate the "Optimize Floating Layering" function. Adjust the "Repair Extent" parameter (higher values provide stronger repair but may alter local details), and the software will automatically repair the layering error.

 

Suggestion: If the layering error is small and you are still scanning, prefer Option 1. If the layering error has formed a large area or the scan has already ended, use Option 2. If layering errors occur frequently, please check device calibration, environmental vibration, or hardware connections.

 

 

 

Q:
When using the 3DeVOK Studio software for scanning, the computer runs very slowly or even crashes. How can this be resolved?
A:

 Please follow the steps below to troubleshoot:

 

Open Task Manager (shortcut: Ctrl + Shift + Esc), go to the "Performance" tab, and check whether the GPU memory usage is close to or has reached 100%.

If GPU memory usage is too high, close other GPU-intensive programs (such as large games, design software, video players, etc.), then retry scanning.

If the issue persists after closing unrelated programs, the current computer's hardware performance (especially GPU memory) may be insufficient. It is recommended to use a computer with higher specifications or upgrade the graphics card.

For further assistance, please contact 3DeVOK technical support with your specific hardware configuration information.

Q:
What is the purpose of saving project files?
A:

After scanning, you can save scan project files, point cloud project files, and mesh project files for data archiving to prevent data loss and facilitate further processing later.

Saving a scan project file allows you to recalculate starting from the real-time scanning stage; saving a point cloud project file enables you to regenerate the mesh from the point cloud stage; saving a mesh project file lets you reapply texture directly from the mesh stage.

Q:
Does 3DeVOK support the Kylinos operating system?
A:

Currently, it does not support.

Q:
Does the black reflective object have a preset scanning mode?
A:

 In the 3DeVOK Studio software,Click the plus sign on the right side of the general mode - Object - open Black or Reflective - return to the Scan Mode interface and select”Black or Reflective” .






Q:

Q:
After opening the 3DeVOK Studio software, it can't import the EPJ file (EPJ is a scanning project file). How can I resolve this?
A:

Reason:

The device has not been connected, and the necessary KSET configuration file is missing.

 

Solution:

01.If there is a device available, simply connect the device, and the software will automatically activate and generate the configuration file.

02.If no device is available, you will need to manually import the KSET configuration file.

Follow these steps:

Copy the "KSET" folder from a USB drive / EPJ folder.

Right-click on the 3DeVOK Studio shortcut and select "Open file location."

Go to the software's root directory (D:\3DeVOK Studio\3DeVOK Studio).

Paste the "KSET" folder and ensure it contains the necessary configuration files

Restart the software, and you should be able to import the EPJ file successfully.

Q:
What do the three parameters—"Memory," "Disk Space," and "VRAM"—at the bottom left of the 3DeVOK Studio scanning software represent?
A:

Memory: determines the computer's ability to run the scanner and process data. If insufficient, scanning fails: so expanding the virtual memory is necessary. Usage above 80% may cause software crashes: the project should be saved immediately.

Disk Space: defines data storage capacity. While it affects file saving, it is unrelated to operational speed.

Video Memory: governs real-time rendering and computing performance. If insufficient, issues such as display abnormalities, data loss, or crashes may arise. If usage exceeds 80%, the project should be saved immediately.

 

Q:
When scanning with marker mode in 3DeVOK Studio scanning software, insufficient markers cause poor alignment, and re-scanning is inconvenient:
A:

①Pause scanning and add markers to sparse areas.

②In the software, enable "Add Mark Points" under "Scan Mode" > "More" > "Common" before resuming.

*Note: New markers aid real-time alignment only and do not affect accuracy calculations. For precision, ensure sufficient markers are attached before scanning.

 

 

Q:
Why the scanner fails to recognize 3mm markers?
A:

If the scanner cannot recognize 3mm markers, it is usually because the option has not been enabled. Please follow these steps:  

- Click to enter the “More” settings menu in the software.  

- Under “Marker”setting, check whether “3mm Markers” is enabled.  

- If it is not enabled: Exit the settings, create a new scanning project, enable “3mm Markers” in the project settings, and then start scanning.  

- If it is already enabled but still not recognized: Ensure that the markers are firmly attached, the surface is clean and non-reflective, and retry under good lighting conditions.

 

Q:
In 3DeVOK Studio scanning software, what is the scan preview mode?
A:

The scan preview mode is a real-time calibration step before scanning begins. After clicking “Start Scan” for the first time, the software enters this mode. The interface displays a live view and distance bar, allowing you to adjust to the optimal scanning distance based on the device type (Infrared: 300–400 mm; Blue Light: 210–300 mm). Once the distance is properly adjusted, click “Start Scan” again to exit the preview mode and begin recording 3D data. This feature is enabled by default and effectively improves the success rate of initial scans, which can be disabled in the settings menu.

 

Q:
Why does the calibration freezes in 3DeVOK Studio?
A:

1. Potential Marker Interference: 

The presence of extraneous marker points near the calibration board or its accessories can cause potential interference, which may stall the calibration process. Please remove any unrelated marker points from the vicinity.

2. Incorrect Board Orientation & Cluttered Environment:

Ensure the calibration board is positioned in the correct orientation as indicated by the software. An incorrectly oriented board can cause calibration to stall.

Keep the area around the calibration board and its accessories clean and free of cluttered objects.

3. The serial number of the calibration board does not match that of the scanner. For instructions on replacing the calibration board, please refer to the FAQ: How to calibrate the 3DeVOK scanner with a non-matching master plate?
