Scanning Software Software that communicates with the HDI 3D scanner. The software acquires 3D data from physical objects and performs basic data editing before exporting it for 3D post-processing.

FlexScan3D PRO

Sample Scan Single 3D image generated from the 3D scanner
Scan Speed Time required to capture a single 3D image. For scanning humans, faster scan speed will produce better scan results

1.3 seconds

0.9 seconds

Resolution The amount of detail the 3D scanner can capture in a single scan. Higher resolution means the 3D scanner can capture more detailed 3D scans.

Field of View The 3D scanner's observable area. A 3D scanner with a larger field of view can scan larger objects.

Adjustable field of view to scan objects of different shapes and sizes

Preset: 165mm, 310mm, 455mm diagonal
Range: 165mm to 1500mm diagonal

Adjustable field of view to scan objects of different shapes and sizes

Preset: 200mm, 400mm, 600mm diagonal
Range: 200mm to 2000mm diagonal

Accuracy How close a measurement is to it's true value. Higher accuracy is better.

165mm diagonal field of view:
35µm (standard deviation: 35µm)
0.0014" (standard deviation: 0.0014")

310mm diagonal field of view:
60µm (standard deviation: 60µm)
0.0024" (standard deviation: 0.0024")

200mm diagonal field of view:
30µm (standard deviation: 35µm)
0.0012" (standard deviation: 0.0014")

400mm diagonal field of view:
50µm (standard deviation: 60µm)
0.002" (standard deviation: 0.0024")

Geometry Formats 3D scanner exports to the following common 3D mesh file formats. Almost all 3D processing applications support these file formats.

PLY, OBJ, STL, ASC, 3D3

Color Texture Standard 3D scanner captures 3D geometry in black and white. Color texture map can be qcquired using a separate Digital SLR camera.

Digital SLR camera required (sold separately).
