Abstract
A sight positioning method, a head-mounted display device, a computer device, and a computer-readable storage medium are provided. The method includes: determining a first transform relation and a second transform relation, where the first transform relation is a transform relation between an image coordinate system and a light source coordinate system, and the second transform relation is a transform relation between the light source coordinate system and a display unit coordinate system; calculating coordinates of a pupil center in the image coordinate system according to an eye image of eyes of a user acquired by the image acquisition equipment; and obtaining coordinates of the pupil center serving as a fixation point position in the display unit coordinate system of the display unit according to the coordinates of the pupil center in the image coordinate system, the first transform relation and the second transform relation.
