How to 3D Scan Black, Shiny, or Transparent Objects with iReal M3 3D Scanner?

03/06/24

In today’s technological landscape, 3D scanners have emerged as indispensable tools, facilitating the conversion of physical objects into digital models. Their applications span across diverse domains such as architecture, medicine, and art.

Despite their versatility, conventional scanners often encounter difficulties when tasked with 3D scanning black, shiny, or transparent materials.

Black surfaces possess a high absorbance of light, shiny surfaces bounce light off their surfaces, and transparent materials refract light. These inherent properties present formidable challenges for scanners aiming to capture accurate 3D data.

In light of these challenges, how can the iReal M3 dual-infrared laser 3D scanner effectively scan such surfaces?

Optimizing Scanning of Black/Dark Objects

When scanning black or dark objects with the iReal M3 infrared speckle mode, adjusting parameters tailored for such surfaces in the iReal 3D Scanning Software can significantly enhance the scanning process.

Optimizing Scanning of Shiny Objects

When scanning highly reflective objects, the infrared laser mode of the iReal M3 proves more effective than the speckle mode. To enhance scanning results, adjust the exposure value accordingly.

The default exposure value for scanning reflective objects is set at 2.0. Should difficulties persist in obtaining model data, gradually increase the exposure value up to 4.0 to improve scanning outcomes.

In addition to exposure adjustments, altering the scanning angle proves effective in mitigating reflections. Experiment with various angles to minimize light reflection and maintain stable lighting conditions during scanning.

Should challenges persist, consider applying a reflective spray to the objects. Specifically formulated sprays can create a uniform film, diminishing reflection impact and facilitating more accurate scanning results.

Optimizing Scanning of Transparent Objects

3D Scanning transparent materials is a complex challenge due to light refraction, hindering accurate shape and detail capture. To address this issue effectively, applying scanning spray powder onto transparent objects is recommended.

This specialized spray aids in optimizing refraction, thereby mitigating its effects and enhancing scan quality for transparent objects.

NOTE: Before using the spray developer, make sure the spray developer is compatible with the objects and follow the instructions for use.
