The booming three-dimensional laser scanning technology can efficiently and effectively get spatial three-dimensional coordinates of the detected object surface and reconstruct the image at high speed, high precision and large capacity of information. Non-radiation, non-contact and the ability of visualization make it increasingly popular in three-dimensional surface medical mapping. This paper reviews the applications and developments of three-dimensional laser scanning technology in medical field, especially in stomatology, plastic surgery and orthopedics. Furthermore, the paper also discusses the application prospects in the future as well as the biomedical engineering problems it would encounter with.
