Since non-event pixel points are not required to participate in the matching of pixel points, even if it is difficult to distinguish between the non-event pixel points or the non-event pixel points are occluded, depth information of the non-event pixel points can be accurately determined according to the location information of neighboring event pixel points.

  • Patent number: 10546423
    Abstract: An augmented reality surgical system includes a head mounted display (HMD) with a see-through display screen, a motion sensor, a camera, and computer equipment. The motion sensor outputs a head motion signal indicating measured movement of the HMD. The computer equipment computes the relative location and orientation of reference markers connected to the HMD and to the patient based on processing a video signal from the camera. The computer equipment generates a three dimensional anatomical model using patient data created by medical imaging equipment, and rotates and scales at least a portion of the three dimensional anatomical model based on the relative location and orientation of the reference markers, and further rotate at least a portion of the three dimensional anatomical model based on the head motion signal to track measured movement of the HMD. The rotated and scaled three dimensional anatomical model is displayed on the display screen.

  • Patent number: 10515103
    Abstract: The disclosure is related to a method and a system for managing viewability of a location-based spatial object. The system provides subscribers to set up searching criteria for every spatial object through the viewability management mechanism. A viewable range for a spatial object is such as a spatial range, a user range and/or a time range. While the system inspects the spatial information and searching criteria of the spatial objects registered in a database, it may be found that the viewable ranges of multiple spatial objects are interfered under the same searching criteria. Thus, the system allows the subscribers to assign ranking weights to different spatial objects for giving them different values. As a result, the system adjusts an order to display the multiple spatial objects according to their ranking weights under the same searching criteria. A search result is displayed through an augmented-reality technology in a terminal device.

  • Patent number: 10503962
    Abstract: A three-dimensional model of an object is employed to aid in navigation among a number of images of the object taken from various viewpoints. In general, an image of an object such as a digital photograph is displayed in a user interface or the like. When a user selects a point within the display that corresponds to a location on the surface of the object, another image may be identified that provides a better view of the object. In order to maintain user orientation to the subject matter while navigating to this destination viewpoint, the display may switch to a model view and a fly-over to the destination viewpoint may be animated using the model. When the destination viewpoint is reached, the display may return to an image view for further inspection, marking, or other manipulation by the user.
