Abstract
A method for calibrating a projection device for a head-mounted display includes scanning a light beam emitted by a light source over a scanning angle range by means of a reflection element such that the light beam deflected by the reflection element passes over a head-mounted display surface region of a deflection element arranged on a lens of the head-mounted display. The surface region has at least two adjustment markings arranged on the head-mounted display, each adjustment marking arranged at a specified position relative to the surface of the deflection element arranged on a lens of the head-mounted display. The method further includes determining in which scan setting of the reflection element the at least two adjustment markings are struck by the light beam.
