Abstract:
1. A method for the determination of optical overlaps of a virtual image of a virtual object and a real image of a real environment, the method comprising: optically recording image points of the real image from an observation pose utilizing an optical recording apparatus; determining first depth positions for the image points of the real image with reference to the observation pose; creating image points from the virtual image of the virtual object based on a pose of the virtual object and the observation pose; calculating second depth positions for the image points of the virtual image with reference to the observation pose; comparing the first depth positions with the second depth positions along an optical axis of the observation pose; visually depicting a first portion of the virtual object that lies behind and would otherwise be hidden by a corresponding image area of the real image relative to the observation pose, wherein the first portion of the virtual object that lies behind the corresponding image area of the real image is visually depicted differently from a second portion of the virtual object that does not lie behind the corresponding image area of the real image; and visually representing the first portion or the second portion of the virtual object as a function of its depth position relative to the corresponding depth position of the corresponding image area of the real image.
