Abstract: Three-dimensional scanning technology has greatly promoted the modernization of apparel companies. It can obtain the three-dimensional information of the human body. Compared with other three-dimensional scanning technologies, millimeter-wave scanning technology is less affected by human dress, avoiding the shortcomings that the tested person must wear specific tights during scanning. This will effectively break through the existing restrictions on dress. On this basis, the millimeter-wave point cloud is calculated and measured, and an anthropometric algorithm based on projection and posture correction is proposed to fit the missing data. The measurement and calculation of the human body characteristic parameters based on the millimeter-wave point cloud are realized and verified that it can realize good human body measurement, which has significant value in theoretical research and practice.

Key words: 3D scanning; millimeter-wave scanning; point cloud model; anthropometry
