A line-of-sight detection method and device, an apparatus, and a storage medium. The method comprises: in monocular vision, obtaining line-of-sight calibration coefficients of both eyes of a user respectively (S110), wherein the line-of-sight calibration coefficients comprise a left-eye line-of-sight calibration coefficient and a right-eye line-of-sight calibration coefficient; and in binocular vision, obtaining line-of-sight data of both eyes of the user on the basis of the line-of-sight calibration coefficients (S120). In the detection method, an eye tracking module is used to detect the user's line of sight, thereby improving line-of-sight detection accuracy.
