What is the difference between blue laser and infrared laser in 3DeVOK MT device?
- Visibility & User Experience:
Infrared lasers operate in the non-visible spectrum, while blue light is visible. This makes infrared scanning more user-friendly (e.g., no glare or visual disturbance). - Material Adaptability:
Blue light is prone to absorption by red/yellow objects, rendering it unsuitable for scanning such surfaces. Infrared exhibits superior penetration and reflection consistency across colors. - Detail Resolution:
Blue light achieves marginally higher detail accuracy, making it ideal for high-precision applications. - Scanning Speed:
With a higher laser line density (34 beams vs. 22 beams), blue light enables faster scanning compared to infrared.
How to choose appropriate scanning modes in 3DeVOK Studio scanning software?
For objects scanned with 3DeVOK MT/MQ, the primary classifications and suggested scanning modes are listed below:
- Matte/textured/multi-colored objects:Laser Scan – Hybrid Alignment / Infrared Structured Light Scan
- Large-scale objects(>30cm): Infrared Structured Light Scan / Marker Alignment
- Human:Human Mode / Lightless Scan
- Glossy black/reflective/detailed components:Laser Scan – Marker Alignment
- Small parts（5-10cm）: Laser Scan – Marker Alignment
After finishing the scanning of markers, why does the scanner continue to capture marker points rather than scanning the object?
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 below) to finish scanning markers. Then click “Start” to scan the object.
What should be noticed when sticking markers?
- Markerplacement: When sticking markers, each marker should be positioned more than 3mm away from the edges or features to ensure the hole-filling algorithm works properly. Otherwise, the marker area may not be filled correctly, affecting the quality of the edge data.
- Distance between markers: The distance between any two points should not exceed 10-12 cm, with 6-8 cm being recommended.
- Marker position: Markers should be stuck on a flat surfaceinstead of a corner or a
Why does the device suddenly generate noise data during scanning?
It is caused by an excessive temperature difference between device calibration and the actual scanning environment. If the temperature difference exceeds 8°C, recalibration is required.
In 3DeVOK Studio software，what is the function of Color Camera Fill Light and Laser Fill Light?
- 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).
What is the difference between Standard Calibration and Fast Calibration in 3DeVOK Studio scanning software?
- 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
Is there a front and back on the 3DeVOK device’s Type-C port for the data cable?
The Type-C port has a front and back. The front side has a raised area at the rear, while the back side has a rectangular indentation in the center, as shown in the image:
How to Evaluate Data Quality in the Relative and Absolute Orientation Stages？
Relative Orientation Stage
- Camera Spatial Pose Check
– For circular shooting, the spatial distribution of cameras should form a circle.
- Sparse Point Cloud Check:
– Sparse point clouds should show no obvious misalignment.
– For objects with fewer surface features, dense reconstruction can help assess the point cloud quality.
After confirming that the relative orientation results are accurate:
– Proceed to absolute orientation and align individual photos to refine the global alignment.
– After completing register, return to the absolute orientation stage to randomly check the camera alignment. If there are no issues, you can proceed to the texturing stage.
Absolute Orientation Stage
- Photo Alignment Check:
– If most photos are correctly aligned but a few are not, it may indicate issues with the relative orientation results.
- Overall Alignment Check:
– If all photos fail to align, it likely indicates errors in absolute orientation.
– For objects with fewer surface features, consider using point cloud and model matching to achieve absolute orientation.
By following these steps, you can systematically ensure the quality of your data.
For reflective objects with few features, how to handle the issue of Assist Patterned Pad reflecting onto the object during photography?
You can print the Assist Patterned Pad provided on the official website, cut it into the shape shown below according to the real size of object. Then place it on the turntable for photography.
After opening the project file, the mesh data node shows that the path does not exist?
Please open the directory where the project file is located, find the Mesh folder, and check if there is any obj file inside. If the obj files exist, please ensure that the project directory name and the obj file names are consistent. If they are not, please modify them to be consistent.
After reinstalling the computer’s operating system, do I need to reapply for authorization for the 3DeVOK Mapping Software?
No, you do not need to reapply for authorization. The ID is bound to the hardware.
