3D machine vision is a necessity in the world of Industrial inspection due to the requirement for efficiency improvement in manufacturing. There is a clear emphasis towards automation and quality control, which are both critical in order to compete.  

The basic principle of 3D structured lighting is the process of projecting a reference illumination pattern onto an object whereby the displacement of the illumination is used to determine dimensional information via triangulation. This data is then processed for different machine vision related inspection tasks.
