Title: The Innovative Contributions of Shangchen Han
Introduction
Shangchen Han is a notable inventor based in Kirkland, WA (US). He has made significant contributions to the field of technology, particularly in the area of object and hand tracking systems. With a total of 4 patents to his name, his work continues to influence advancements in computer vision and user interaction.
Latest Patents
One of Shangchen Han's latest patents is focused on passive object tracking using a camera. This innovative system tracks the poses of a passive object by utilizing fiducial markers on the object's polygonal structure. The system employs an object tracking controller that generates an estimated pose for image data frames through approximate pose estimation (APE) and refines it using dense pose refinement (DPR). The APE minimizes reprojection error between projected and observed image points, while the DPR focuses on minimizing appearance error between image pixels and projected model pixels.
Another significant patent involves hand tracking using a passive camera system. This system processes image data captured by one or more passive cameras to track a user's hands. The hand tracking unit applies a neural network model to the image data to create heat maps that indicate the locations of hand features. This technology allows for accurate hand pose determination, which can be used for user input or to render the hand in displays, such as head-mounted displays.
