Latest Patents

One of Xu Yang's latest patents is a low-complexity panoramic video coding method considering distortion temporal propagation. This innovative method analyzes inter-frame reference relationships under a random access coding structure and establishes a corresponding distortion propagation chain. By utilizing distortion impact factors of coding units, the method optimizes the encoding process by adjusting encoding parameters. Additionally, it addresses oversampling issues caused by varying geometric deformations in different latitude regions during the projection of spherical images in panoramic videos. This approach significantly enhances coding performance.

Another notable patent is the active intelligent wellbore pressure control system. This invention includes a ground multi-parameter online monitoring system, a rotary blowout preventer, a wellhead back pressure compensation manifold, an automatic plugging material filling device, a drilling device, an MPD intelligent control system, a remote monitoring and control system, and a high-precision hydraulic calculation system. The system provides a wellbore pressure control strategy that integrates plugging and control, improving the pressure resistance of formations while drilling. It effectively broadens the “drilling safety density window” of the formation and expands the application range of managed pressure drilling technology.
