Patents by Inventor Chuangqi TANG

Chuangqi TANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11610330
    Abstract: A pose tracking method and apparatus are disclosed. The pose tracking method includes obtaining an image of a trackable target having a plurality of markers, detecting first points in the obtained image to which the markers are projected, matching the first points and second points corresponding to positions of the markers in a coordinate system set based on the trackable target based on rotation information of the trackable target, and estimating a pose of the trackable target based on matching pairs of the first points and the second points.
    Type: Grant

  • Patent number: 11488320
    Abstract: A pose estimation method includes obtains an event stream from an event-based vision sensor configured to capture a target object to which light-emitting devices flickering at a predetermined first frequency are attached, obtains a polarity change period of at least one pixel based on the event stream, generates an image frame sequence using at least one target pixel having a polarity change period corresponding to the first frequency, among the at least one pixel, extracts a feature sequence including feature vectors corresponding to the at least one target pixel, from the image frame sequence, and estimates a pose sequence of the target object by applying the feature sequence to a deep neural network (DNN) model.
