Description and Application

Structured light is a system consisting of a projector and a camera. The projector projects specific light patterns onto the surface of an object and the background, and the camera captures the reflected patterns. By analyzing the changes in light signals caused by the object, information such as the object's position and depth can be calculated, allowing for the reconstruction of the entire three-dimensional space. As a three-dimensional scanning device using structured light as a light source, it can create a point cloud of the object's geometric surface. These points can be interpolated to form the surface shape of the object. Denser point clouds can create more accurate models, which are used to detect and analyze the shape and appearance data of objects or environments in the real world. The collected data is often used for 3D reconstruction calculations to create digital models of real objects in the virtual world.
