Abstract
The present disclosure relates to a method for calibrating a camera of a head-mounted display, HMD. The method comprises providing a calibration target in front of a lens of the HMD. Each of the calibration target and the lens basically extend in a corresponding two-dimensional plane. The method further comprises determining a lateral position of the calibration target. The lateral position relates to a position of the calibration target in the two-dimensional plane. The method even further comprises determining a lateral position of the lens. The lateral position relates to a position of the lens in the two-dimensional plane. The method yet even further comprises determining a calibration target misalignment based on the determined lateral position of the calibration target and based on the determined lateral position of the lens. The method also comprises performing a hardware calibration of the HMD. The hardware calibration is adapted for the calibration target misalignment. The present disclosure also relates to an arrangement and a computer program product.
