Structured light scanning

Definition

Structured light scanning is a 3D scanning technique that projects a series of light patterns onto an object to capture its shape and surface details. This method captures the deformation of the light patterns caused by the object's contours, which are then analyzed to create a detailed 3D point cloud representation of the object. This technology is crucial for applications like industrial inspection and 3D modeling, providing precise measurements and facilitating quality control.

5 Must Know Facts For Your Next Test

1. Structured light scanning can achieve high accuracy, making it suitable for applications requiring precise measurements, such as in industrial settings.
2. The technology works by analyzing how projected light patterns distort when they hit an object's surface, allowing for detailed geometric representations.
3. This scanning technique is often faster than traditional methods like laser scanning because it captures multiple data points simultaneously.
4. Structured light scanners are commonly used in quality control processes to detect defects or deviations in manufactured parts.
5. This method can also be utilized in reverse engineering, helping to create digital models of existing physical objects for design and analysis.
