    V2I Work Zone Geometry Reconstruction with Pose-Conditioned UWB Range Denoising

    Researchers have developed a new method for reconstructing work zone geometry using ultra-wideband (UWB) range data from connected and autonomous vehicles (CAVs). This approach utilizes a pose-conditioned, permutation-equivariant predictive denoiser to improve the accuracy of UWB range estimations, which are often degraded by outliers and non-line-of-sight errors. The system incorporates vehicle motion as a geometric prior and was evaluated on real-world field data, showing a significant reduction in measurement-weighted mean squared error. AI

    Ultra Diffusion Poser: Diffusion-Based Human Motion Tracking From Sparse Inertial Sensors and Ranging-Based Between-Sensor Distances

    Researchers have developed Ultra Diffusion Poser, a new diffusion model for human motion tracking that integrates data from sparse inertial sensors and ultra-wideband (UWB) ranging. This model explicitly accounts for the geometric constraints imposed by UWB distance measurements, which were previously underutilized. By reconstructing the 3D sensor layout and using this information alongside IMU signals, the model significantly improves pose estimation accuracy, achieving up to a 22% reduction in joint position error compared to existing methods.
