The projector casts a structured light pattern, which can be either stripes, grids, or dots, onto the object's surface. The resulting distortions of the projected pattern reveals the object's solid geometry through. The LTPRHP3W series features advanced and efficient LED projectors for structured light applications such as, quality control, 3D reconstruction, 3D profilometry, stereovision, planarity control, robot guidance for pick and place and alignment applications. Unlike laser sources, which typically. ams OSRAM offers image sensors, micro cameras, flood and dot illuminator modules to enable passive stereovision, structured light and active stereovision 3D sensing systems. Passive vision systems capture multiple images of the scene from different positions.
