Enhancing Precision: Using our new DecaMarkers Registration Targets for Small or Complex Parts in 3D Scanning



In the realm of 3D scanning, accuracy and precision are paramount. Whether for quality control, reverse engineering, or replication, capturing detailed and intricate information about small or complex parts is often a challenging task. However, the use of registration targets can significantly improve the accuracy of 3D scans for such components. In this article, we explore the importance of registration targets and how they can elevate the quality of 3D scans in scenarios involving small or complex parts.

The Challenge of Small and Complex Parts

Small or intricately designed parts pose unique challenges for 3D scanning. These components may have intricate details, sharp edges, or fine surface textures that can be difficult to capture accurately with standard scanning techniques. Moreover, their size can make it challenging to apply markers and to align multiple scans or ensure that all parts of the object are adequately captured.

The Role of Registration Targets

Registration targets, also known as reference markers or alignment aids, are physical objects placed strategically on or around the part being scanned. These targets are often made of contrasting materials or feature distinctive patterns that can be easily detected by the 3D scanner’s sensors. Their primary purpose is to aid in the alignment and registration of multiple scans, ensuring that they can be accurately merged into a single, cohesive 3D model.

Advantages of Using Registration Targets

  1. Enhanced Precision: The most significant advantage of registration targets is the improvement in scan precision. By providing clear reference points, they enable the scanner to establish accurate spatial relationships between different scan data sets. This is particularly important when dealing with intricate parts where precision is critical.

  2. Alignment of Multiple Scans: For larger objects or parts with complex geometries, it’s often necessary to capture multiple scans from different angles. Registration targets streamline the alignment process, making it easier to merge these scans into a complete 3D model without inaccuracies or misalignments.

  3. Mitigating Data Loss: Small parts can be easily overlooked during scanning due to their size. Registration targets can be strategically placed to ensure that all aspects of the part are captured, reducing the risk of data loss or incomplete scans.

  4. Time Efficiency: Using registration targets can significantly reduce the time required for post-processing and alignment. This is particularly beneficial for industries where efficiency and productivity are essential.

Best Practices for Using Registration Targets

To maximize the benefits of registration targets when 3D scanning small or complex parts, consider the following best practices:

  1. Strategic Placement: Carefully plan the placement of registration targets to cover critical areas of the part and ensure comprehensive coverage.

  2. Contrasting Colors and Patterns: Use targets with colors or patterns that provide a strong contrast to the part’s surface, making them easily detectable by the scanner’s sensors.

  3. Multiple Targets: Place multiple targets within the field of view of each scan to ensure redundancy and robust registration.

  4. Calibration: Ensure that your 3D scanner is properly calibrated to accurately detect and register the type of targets you are using targets.


In the world of 3D scanning, precision and accuracy are essential, especially when dealing with small or complex parts. Registration targets play a crucial role in enhancing the quality of scans for these challenging scenarios. By strategically placing and utilizing these markers, you can significantly improve the accuracy, efficiency, and completeness of your 3D scans. Whether you are in the field of manufacturing, design, or quality control, the incorporation of registration targets is a valuable strategy for achieving exceptional results in 3D scanning applications involving small or intricate components.

Our multisided DecaMarkers allow easy data capturing from all sides and these come with retroreflective 6mm dia markers or you can order them blank and use your own reference markers! These can be used with any 3d scanning system whether its whitelight, bluelight or laser scanners or any brand it makes no difference.
