Introduction

3D scanning is the process of analysing a real-world object, person or environment to collect data (or create digital models). - Sculpteo

Best Practices

1. Proper Object Preparation

• Clean the Object: Ensure that the object is free of dust, dirt, or debris, as these can affect the accuracy of the scan.

• Choose a Suitable Object: Highly reflective, transparent, or very dark surfaces can be difficult to scan. Apply a temporary matte spray if necessary to make the surface more scannable.

2. Optimize Scanning Environment

• Good Lighting Conditions: Use diffuse, even lighting to avoid harsh shadows or reflections. This is crucial when scanning with photogrammetry, as light variations can distort the 3D model.

• Stable Surface: Place the object on a stable surface to avoid any movement during the scan. For larger objects, ensure the scanning environment is free of vibrations.

3. Avoid Common Pitfalls with Surface Types

• Reflective or Glossy Surfaces: These can cause problems by reflecting light, confusing the scanner. Apply a temporary matte spray to dull the surface temporarily.

• Transparent Objects: Scanners often struggle with transparency. You can add white paper on it, apply a spray to make it opaque or wrap the object in non-reflective tape.

• Thin and Flat Objects: Use a contrasting background to help the scanner distinguish edges. For thin objects, scan both sides and merge the results in post-processing.
