FAQ - 3DeVOK Studio Scanning Software

Two primary factors significantly impact point cloud processing duration:

• Resolution: Higher resolutions(smaller values) increase processing time.
• Scanning Duration: Longer scans directly result in longer computation times, for every frame captured is being processed after finishing scanning.

Below the “Finish” button, there are two options: “Partial Data Retention” and “Complete Data Retention” When processing data, the software defaults to “Partial Data Retention”

Partial Data Retention: Only retain point clouds displayed as green in color map

Complete Data Retention: Retain all data including point clouds displayed as red in color map

When the texture dims due to disabled fill light, adjust the color camera’s exposure brightness in the Real View on the right to compensate.

3DeVOK Studio offers four measurement modes: volume, circumference, area, and distance. Additionally, it provides a data alignment feature to adjust object coordinates, which can be found in Mesh Project.

Click on the camera view button at the top right corner of the software to view the real-time brightness of the laser line. Based on the brightness of the laser line, adjust the brightness in the real-time parameters section on the left sidebar.

Note:

Left: Underexposed, which results in failed point cloud generation

Middle: Optimal laser brightness for scanning

Right: Overexposed, which leads to poor point cloud generation, rough data surface and excessive noise

• Auxiliary Fiducial Markers requires at least one marker at every FOV, while hybrid alignment only necessitates markers in areas with insufficient geometric features. Theoretically, the former requires more markers than the latter.
• Auxiliary Fiducial Markers prioritizes marker detection first in order to prevent geometric feature misalignment. While Hybrid Alignment recognizes texture first, then geometry, markers the last.

• 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.
