[0158] In the experiment, a 3D laser scanner was first used to acquire a 3D model of an unknown source skull, such as figure 2 shown. The sex of the skull is then determined by measuring the geometrical measurements of the skull. The distribution of facial soft tissue directly affects the results of facial restoration. Therefore, in order to improve the reliability of facial restoration, the relationship between facial soft tissue distribution and gender and age distribution is analyzed based on the craniofacial database, and multiple factors such as age, gender, and appearance are considered. craniofacial classification library. Based on other clues left at the criminal investigation scene, forensic experts speculated on the age and appearance of the skull of the unknown source. For each craniofacial sample in the craniofacial classification database that conforms to the properties of the skull of unknown origin, the face restoration method based on dense point registratio...
