Optical monitoring of scoliosis by 3D medical laser scanner

•This paper proposes a robust way to obtain a digitized map of human body.•The vision system has a 98% confidence level on its coordinate′s measurements.•The use of Levenberg–Marquardt method still increases the accuracy up to 99.98%.•The use of Energetic centre search method provides satisfactory spatial resolution.

Three dimensional recording of the human body surface or anatomical areas have gained importance in many medical applications. In this paper, our 3D Medical Laser Scanner is presented. It is based on the novel principle of dynamic triangulation. We analyze the method of operation, medical applications, orthopedically diseases as Scoliosis and the most common types of skin to employ the system the most proper way. It is analyzed a group of medical problems related to the application of optical scanning in optimal way. Finally, experiments are conducted to verify the performance of the proposed system and its method uncertainty.
