FAQ - 3DeVOK Scanner

The dual black-and-white cameras are mounted at a specific angle to each other, and the optimal scanning angle occurs when both cameras can detect the target object at near-vertical incidence angles. Point B yields the highest point cloud density, while points A and C produce the sparsest data. For challenging areas or dead zones, the scanner can be re-positioned to ensure simultaneous object visibility by both cameras.

For optimal scanning results, maintain a working distance between 200mm and 400mm to achieve the highest point cloud quality and finest detail resolution.

Optimal scanning distance of Infrared Structured Light Scan: 300 mm

Optimal scanning distance of Infrared Laser: 300 mm

Optimal scanning distance of Blue Laser: 210 mm

This advanced mode enables simultaneous recognition of:

• Geometric features(surface contours/edges)
• Texture features(natural patterns)
• Markers(when applied)

The hybrid alignment mode improves scanning performance through:

• Enhanced alignment accuracy
• Reduced marker dependency(enabling scans with:

1. Zero markers for textured objects
2. 3-5 markers for low-feature surfaces)

• 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.

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.

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:

A: The first six steps of the standard calibration involve calibrating the laser lines. When the scanner is raised to a certain height, the laser lines on the edges may extend beyond the master plate, causing the laser lines to disconnect. To address this issue, the 4 expansion accessories is used as an accessory to ensure proper calibration.

The reference distance (optimal scanning distance) of iReal 2E is 400mm. The effective scanning distance range is 280-1000mm, so its scanning depth of field is 720mm, which gives the operator more freedom and makes it easier for beginners.

1. Basic accuracy: up to 0.100 mm;
2. The highest alignment accuracy is 0.300 mm/m, the specific verification method: 3D scan the item with standard length (1m) in the marker alignment mode to obtain the deviation between the sphere center distance and the standard value (after multiple sets of tests), and the obtained alignment error value is called the accuracy.
3. Notes: it is suggested that with a higher requirement for accuracy, it is suggested to choose SCANTECH 3D’s industrial 3D laser scanner with better stability and precision. The highest accuracy of an industrial-grade 3D laser scanner can reach 0.02 mm+0.015 mm/m.
4. Notes for the three alignment modes without markers (feature alignment, texture alignment and mixed alignment): it has strong uncertainties for the alignment result based on geometric features and texture features, the scanning skills and the condition of the surface of the scanned object will affect the accuracy of the feature alignment and the texture alignment. Therefore, in feature alignment, texture alignment, or mixed alignment, there is no certain accuracy value of the alignment. The final result depends on real-life practice.

It can achieve 10 frames per second (1,000,000 points per second of the biggest scanning speed) under the standard mode. When the computer memory is equal to or larger than 6G, you can adjust the frame rate to 15 frames per second (1,500,000 points per second of the biggest scanning speed) in the 3DeVOK Studio software settings.

The bigger the frame rate is, the more features a single frame can capture, and the smoother the (geometric) feature alignment will be.

iReal 2E is equipped with three sets of built-in cameras: two sets of industrial black and white cameras and one set of color camera, all three pixels are 1.3 million.

Notes: Although higher pixel brings a higher quality of the image captured per single frame, it is true that those cameras with higher pixels tend to have much higher requirements for data transferring, real-time calculation and PC configuration. Therefore, cameras with 1.3 million pixels are relatively cost-effective for iReal 2E after a comprehensive consideration.
