Structured Light
Structured Light is a computer vision technique that projects a known pattern of light (e.g., stripes, grids, or dots) onto an object and uses a camera to capture the deformation of this pattern. By analyzing how the pattern distorts on the object's surface, it enables precise 3D reconstruction, depth sensing, and surface measurement. This method is widely used in applications like 3D scanning, motion capture, and industrial inspection.
Developers should learn Structured Light when working on projects requiring high-accuracy 3D modeling, such as in robotics for object recognition, in manufacturing for quality control, or in augmented reality for realistic environment mapping. It is particularly useful in scenarios where contactless measurement is needed, offering advantages over other depth-sensing methods like stereo vision in controlled lighting conditions due to its precision and reliability.
