  • Publication number: 20220413293
    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.

  • Patent number: 11422619
    Abstract: A tracking method for tracking a head-mounted device includes following steps. First pose data of the head-mounted device is tracked in an inside-out coordinate system. Second pose data of the head-mounted device is tracked in an outside-in coordinate system. A transformation relationship between the inside-out coordinate system and the outside-in coordinate system is calculated according to the first pose data and the second pose data. The first pose data in the inside-out coordinate system is transformed into third pose data in the outside-in coordinate system according to the transformation relationship. In response to that the second pose data is currently available, the second pose data is utilized to determine a device pose of the head-mounted device. In response to that the second pose data is currently unavailable, the third pose data is utilized to determine the device pose of the head-mounted device.
