Latest Patents

Hsiao’s listed recent inventions address camera calibration and load balancing.

- **Camera calibration method and camera calibration system.** This invention describes calibrating a camera using two line segments in a space. By measuring their heights and image coordinates, the method calculates camera parameters, including focal length, rotation angles, and translation components. It also uses a reference direction and point to determine additional camera parameters.

- **Load balancing system, load balancing device and topology management method.** This invention manages video streams across edge servers. It tracks transmission progress, groups servers by the streams they provide, and identifies a stream associated with a heavily loaded server. The system can synchronize that stream’s video data to another server, align the servers’ progress values, and add the receiving server to the relevant group.
