Latest Patents

Qifu Zhu holds a patent for a "Method for correcting a 3D location measured by a tracking system assuming a vertical offset." This patent focuses on correcting position measurements by a tracking system associated with a survey tool, which are often affected by tilt. The tracking station typically has an offset from the surface being surveyed, leading to angular displacement as the tool tilts. The system records the 3D position of the survey tool, which can include angular offset errors. Zhu's invention utilizes an inertial measurement unit (IMU) and dual-axis inclinometers to measure angular offsets, allowing for the correction of position data. This correction is crucial for accurate processing of measurement data, such as Ground Penetrating Radar (GPR) readings, to produce images of sub-surface features.
