Latest Patents
One of Long Qian's latest patents is a "Calibration system and method to align a 3D virtual scene and a 3D real world for a stereoscopic head-mounted display." This innovative calibration platform is designed to obtain measurements for aligning a real-world coordinate system with a display coordinate system. It utilizes an optical see-through head-mounted display (OST-HMD) to display a three-dimensional virtual object while receiving information from a positional tracking device about the current pose of a real-world object. The platform records the three-dimensional position of multiple points on the real-world object, generating a transformation function that maps points between the two coordinate systems.
Another significant patent is the "Blink-based calibration of an optical see-through head-mounted display." This system allows the calibration platform to display a virtual image with specific features. It determines when a user performs a voluntary eye blink to indicate alignment between the virtual image and a point on a real-world object. The platform records this alignment measurement, which is then used to create a mapping function between the real-world coordinate system and the display space of the OST-HMD.
