Abstract

A measure method and a measure device are provided. The measure method includes: scanning a face of a testee wearing a positioning frame to obtain pupil positions, visual directions, and a 3D face model, the 3D face model wears a positioning frame model corresponding to the positioning frame; superposing a 3D glasses reference model on the positioning frame model of the 3D face model; calculating an inner intersection point of the visual directions and the 3D glasses reference model; and calculating out a back vertex distance according to the pupil positions and the inner intersection point and calculate an angle between a lens plane line of the 3D glasses reference model and a space vertical line to regard as a pantoscopic tilt.
