Latest Patents

One of Guijin Wang's latest patents is titled "Method and system for automatic focusing for high-resolution structured light 3D imaging." This invention provides an improvement to digital fringe projection techniques by automatically determining optimal focal length settings for reconstructing a 3D profile. The process involves a pre-calibration phase where geometric parameters are calibrated using discrete focal length settings. These parameters are then fitted onto a continuous function model. In the 3D autofocusing phase, optimal focal length settings for a scene are determined using a 2D autofocusing technique, allowing for the automatic calculation of calibrated geometric parameters. Ultimately, a 3D profile of objects in the scene is reconstructed using these parameters.

Another significant patent is "Channel and quality of service adaptation for multimedia over wireless networks." This invention presents a cross-layer architecture for delivering multiple media streams over 3G W-CDMA channels in adaptive multimedia wireless networks. It features a resource management mechanism that dynamically allocates resources among different media streams based on channel status and Quality of Service (QoS) requirements. By considering the time-varying wireless transmission characteristics, the allocation of resources is performed based on a minimum-distortion or minimum-power criterion.
