Structured light systems

Definition

Structured light systems are advanced imaging techniques used to capture three-dimensional shapes and surfaces by projecting a known light pattern onto the subject. This method enables the accurate measurement of depth and surface details, making it essential for applications like volumetric capture and 3D video production. By analyzing the deformation of the projected pattern on the object's surface, these systems can create precise 3D representations.
