Fringe projection is a technique used in 3D measurement and scanning applications to capture the surface topography of objects. It involves projecting a pattern of fringes onto an object and analyzing the deformation of these fringes when they are captured by a camera. By measuring the phase shift of the fringes, accurate 3D information can be obtained. Fringe projection is commonly used in industries such as automotive, aerospace, and archaeology for applications like quality control, reverse engineering, and cultural heritage preservation. This technique is highly versatile and provides high-resolution and accurate 3D data, making it a valuable tool in various fields.
