What Is a 3D Scanner?

3D scanner is a kind of image name for 3D scanner, which is 3D scanner.

3D stereo scanner

The first generation is characterized by point-by-point scanning, slow speed and high accuracy of 0.001mm. Such as CMM

· The second generation is characterized by line-by-line scanning, and the speed is still slow. For example, the laser line scanner has a poor accuracy of 0.05mm.

· The third generation is characterized by surface scanning, which is very fast, such as the OKIO 3D scanner, which has a higher accuracy of 0.01mm

Three-dimensional optical scanners are divided into two categories according to their principles, one is "photographic" and the other is "laser", both of which are non-contact, that is, when scanning, these two devices are not Need to be in contact with the measured object.

"Laser" scanners belong to earlier products. The scanner emits a laser light band. When the light band is irradiated on the measured object and moves on the measured object, the actual shape of the object can be collected. "Laser" scanners are generally equipped with articulated arms.

"Photographic" scanners are a new generation of scanners for industrial products,

· Measure one surface at a time, the scanning speed is extremely fast, more than 1 million points can be obtained in a few seconds · Portable, can be moved to the scene for measurement

· The workpiece or measuring head can be adjusted at will to facilitate measurement

· Large depth of field (up to 300 ~ 500mm)

Large measuring range

·High precision

Measurement point distribution is very regular

· Block measurement of large objects

1. Non-contact scanning: Use the principle of photography to perform non-contact optical scanning to obtain three-dimensional data on the surface of the object. 2. Very fast scanning speed: Unique surface scanning method, extremely fast (single-sided scanning time is less than 5 seconds).

3. High accuracy: Using unique measurement technology, very high measurement accuracy can be obtained.

4. High-density sampling points: The high-performance measuring head can obtain extremely high-density point cloud data at one time.

5. Portable design: All components are flexible, reliable, and easy to move, and can be measured according to the actual situation on site.

6. Flexible scanning method: Supports marker point stitching and turntable stitching. The results of multiple measurements can be synthesized through the stitching of landmark points, from

And realize ultra-large area scanning. Using the turntable stitching can rotate the object flexibly, thereby reducing the measurement

Dead end.

7. Insensitive to environmental conditions: High-performance optical and mechanical components can be used to obtain high-performance data in most environments.

8. Friendly operation software interface: highly integrated and intelligent design, so that users can operate proficiently without excessive training regardless of their experience.

9. Point cloud noise processing and trimming: The noise points generated by the measurement can be trimmed and eliminated.

10. Extensive data output data interface: measurement results are output in asc format, which can be used with surfacer (imageware),

UG, CATIA, Geomagic, Pro / e, MasterCAM and other software exchange data.

11. Good compatibility: compatible with Windows98 / NT / 2000 / XP platforms, easy to learn.

1) CAD / CAM / Reverse Engineering (RE) / Rapid Prototyping (RP):

· Scan real objects to establish CAD data; or scan models to establish 3D data for detecting the surface of parts; · For parts that cannot use 3D CAD data, establish data · Use real models created by RP to establish and improve product designs, limited Data capture for meta-analysis.

2) Inspection (CAT) / CAE: Production line quality control and shape detection of curved parts

3) Scientific research: computer vision, computational geometry, archeological research

4) Other applications: entry and electronic display of cultural relics, artworks, animation modeling, dental and orthodontic correction, cosmetic surgery and maxillofacial surgery
