FAQ - 3DeVOK Studio Scanning Software

• 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 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.

The method and steps for calibrating white balance are as follows:

1. Take out the gray card from the case and position it face-up on a light-color surface.
2. Select the “White Balance Calibration ” function on the left, and process the calibration following the on-screen instructions, as shown in Figure 6-3.
3. Align the scanner perpendicularly to the gray card surface, adjust the distance until the position indicator enters the yellow target frame on the user interface.
4. Maintain a vertical standoff distance of 300 mm between the scanner and the gray card.

Note: In which situations is white balance calibration required?

• Environmental Change Between Scans (e.g., outdoor-to-indoor transition).
• Color Deviations (e.g., significant hue/saturation deviation during real-time preview)
• Complex Ambient Lighting (e.g., Mixed artificial light sources (e.g., red/green dominant illumination)

Select Infrared Laser and Marker Mode in scanning mode, and click settings to enable Color Camera Fill Light. When the option is turned on, the maximum scanning frame rate will drop from 70 FPS to 30 FPS.

• Color Camera Fill Light: Enhances surface texture recognition and provides color mapping.If it is disabled, it degrades texture stitching and color data quality. Keep enabled when using hybrid alignment or requiring color data.
• Laser Fill Light: Help recognizing markers. Manually enable it when using structured light or laser with hybrid alignment (requires markers).

• The Standard Calibrationoffers more comprehensive calibration steps and higher precision than the Fast Calibration option.
• Standard calibration requires matching the device with its correspondingmaster plate, whereas quick calibration works with any calibration board.

Standard Calibration: 17 steps

Fast Calibration: 7 steps

The position and color of the overlapping point clouds are comprehensively sampled from the two sets of original data and finally merged. Additionally, there is an upper limit for the point cloud density.

When some customers download 3DeVOK scanning software, 3DeVOK intelligent mapping assistant or other related files using the channels provided by 3DeVOK’s official website, they may encounter a browser pop-up window “virus exists” after the download is completed.

In this case, you need to complete the following operations in the computer settings:

Open the computer system settings and enter the “Security Center – Virus and Threat Protection” interface. Turn off “Real-time protection”, “Cloud-provided protection” and “Automatic sample submission“.

Once you have done the above, you can download the software normally!

(The files downloaded from the 3DeVOK website are virus-free and pose no threat to your computer’s security, so please feel free to download them!)

Anomalies:

After the available RGF license file is downloaded and replaced by other means such as WeChat, the software still does not work.

Solution:

1. Right-click the RGF file to open the Properties

2. Uncheck “Read Only” and click “OK”

3. Re-open the scanning software and configure it.

3DeVOK Studio scanning software supports a total of 3 types of 3D projects: Scan Project, Point Cloud Project and Mesh Project.

1. When you save the Scan Project, if you do not move the scanned item, you can reopen the scan project and continue to scan the data to prevent some parts from being missed during the first scan, resulting in incomplete data.
2. Save the Point Cloud Project, you can use “Model Splicing” to stitch and merge the data, and merge the texture files in the two projects at the same time, when the stitching is completed, you will start the calculation from the point cloud step.
3. Regarding the Mesh Project, replace the STL file with the optimized STL file. After opening it again, you can re-map, but the structure and spatial position of the model should not be too different so that the texture will not be misplaced.

Usually, the 3D data in stl/obj/asc formats are the most commonly used 3D data formats. The stl format has no color texture, and the obj format has color textures. When you save an obj file, 3 files will be saved together: obj, mtl, and png. Without mtl and png, obj is equal to stl, with no color tuxture. The mtl file is like a bridge, it combines the obj and png.
