  • Patent number: 11822089
    Abstract: Disclosed are systems and methods for superimposing a virtual image on a real-time image. A system for superimposing a virtual image on a real-time image comprises a real-time image module and a virtual image module. The real-time image module comprises a magnification assembly to generate a real-time image of an object at a first location and a first depth, with a predetermined magnification. The virtual image module generates a virtual image by respectively projecting a right light signal to a viewer's right eye and a corresponding left light signal to a viewer's left eye. The right light signal and the corresponding left light signal are perceived by the viewer to display the virtual image at a second location and a second depth. The second depth is related to an angle between the right light signal and the corresponding left light signal projected to the viewer's eyes. The second depth may be approximately the same as the first depth.
