This article aims to introduce how to create a fast and robust 3D scanner using XIMEA Currera-R camera for industrial environments. The primary goal is to design and develop a fast and high precision active triangulation 3D scanner based on the advantages of Currera versatile camera and the latest 3D industrial profiling techniques. The Basics of Triangulation section introduces a fast active triangulation technique followed by several implementation methods regarding the camera and laser position. In the Laser Profile Analysis paragraph the most common measurement problems are presented that occur in noisy environments; a new laser peak detection technique with the aim of reduce noise derived from reflection of the object or insufficient lighting condition; and a dimensionally stable interpolation method in order to provide accurate profile.
