Structured light scanning, also known as structured light 3D scanning or fringe projection, is a technique used to capture the three-dimensional geometry of objects. This non-contact, optical measurement method projects a known pattern, such as a grid or stripes, onto the surface of an object. A camera then captures the deformation of this pattern as it conforms to the object's shape. By analyzing these deformations, the system can calculate the surface geometry of the object in three dimensions.

The process typically involves projecting a series of patterns, often using a digital light processing (DLP) projector or similar device. These patterns can include various types of structured light, such as binary patterns, gray code patterns, or sinusoidal patterns. The camera captures images of the object with these patterns projected onto it. The system then uses algorithms to analyze the captured images and reconstruct the 3D shape of the object.

Structured light scanning is widely used in various applications, including quality control, reverse engineering, and medical imaging. It offers high accuracy and resolution, making it suitable for capturing fine details and complex geometries. However, it is generally limited to stationary objects and controlled environments, as factors like ambient light and object movement can affect the quality of the scan.

The technology behind structured light scanning has evolved significantly, with advancements in hardware and software improving its speed, accuracy, and ease of use. Modern systems can capture detailed 3D models quickly, making them valuable tools in industries ranging from manufacturing to healthcare. Despite its limitations, structured light scanning remains a powerful and versatile method for 3D data acquisition.
