Structured Light 3D Scanning

Structured light scanning technology involves projecting a known pattern of light onto the surface of an object, and then using cameras to capture the deformations of this pattern on the object's surface.

Precision and Speed:

Our Einscan SP scanner can achieve high-precision, detailed and accurate 3D models well-suited for a wide range of applications. With the Auto Scan mode, Einscan uses a turntable with built in markers to capture objects from a 360° angle. With automatic alignment, the scanner is designed to capture data quickly. 

Color Texture Mapping:

In addition to capturing geometry, the Einscan SP scanner can also capture color information. This allows for the creation of visually realistic 3D models with detailed color texture mapping.

User-Friendly Operation:

The scanner is designed with user-friendliness in mind. Intuitive software and easy-to-use controls make the scanning process accessible to both beginners and experienced users, ensuring a smooth workflow.

Common Limitations:

Reflective, Translucent or Transparent Surfaces:

Structured light scanners may struggle with highly reflective surfaces, such as mirrors or polished metals. The reflection of the projected light pattern can interfere with the accuracy of the captured data. To overcome this, anti-reflective coatings or alternative scanning technologies may be used. Transparent or translucent objects can pose challenges as the light pattern may pass through these materials.

Limited Field of View:

In automatic turntable mode our scanner has a capacity of 7.8” (200mm) cubed. With larger objects it is necessary to perform multiple scans from different angles to capture the entire object. This can be time-consuming and may require additional post-processing to align the scans accurately.

Complex Geometries: 

Objects with intricate and recessed features may pose challenges for structured light scanners. Shadows and occlusions in these complex areas can affect the accuracy of the scan. Complementary scanning methods or multiple scanning passes may be needed to capture all details.
