Method for calibrating, in an automated manner, a virtual retinal scan display for a pair of smart glasses, calibration device, and virtual retinal scan display

A method for calibrating, in an at least largely automated manner, a virtual retinal scan display for a pair of smart glasses including multiple exit pupils that are spaced apart from one another without overlapping, in a provided pupil plane of the virtual retinal scan display, the method comprising the following steps:

• in at least one calibration step, automatically translating and/or rotating an eye-like camera in the provided pupil plane of the virtual retinal scan display in such a way that at least two exit pupils of the virtual retinal scan display are each sequentially captured from different positions and/or angles of the eye-like camera,
• wherein, in at least one substep of the calibration step, geometric distortions of the exit pupils of the virtual retinal scan display are determined by positioning the eye-like camera at ascertained or at defined positions and angles in the provided pupil plane of the virtual retinal scan display and by the positioned eye-like camera recording test patterns projected into the exit pupils, and
• wherein the test patterns projected by the virtual retinal scan display into the exit pupils are composed, digitally, of individual partial patterns projected in chronological succession by the virtual retinal scan display and recorded in chronological succession by the eye-like camera.

• wherein, in at least one substep of the calibration step, full-area, homogeneously monochrome, images are projected into the exit pupils, from which brightness profiles of the exit pupils of the virtual retinal scan display are determined by positioning the eye-like camera at ascertained or at defined angles in the provided pupil plane of the virtual retinal scan display and by the positioned eye-like camera recording the projected full-area images in the exit pupils.

• wherein, before and/or after at least one substep of the calibration step, the eye-like camera is moved in such a way that a further sensor motion-connected with the eye-like camera is superimposed at least with an exit pupil of the virtual retina scan display that is:
• (i) currently recorded, and/or (ii) recorded immediately afterward, and/or recorded immediately beforehand.
