Deep Learning-Based Vehicular IMU Calibration
Developed a deep learning framework to detect vehicle stationary states, utilizing zero-velocity updates (ZUPT) and gradient descent optimization to calibrate accelerometer bias, scale, and cross-talk.
Polarised-Light-Aided Magnetometer Calibration
Developed an online calibration filter fusing celestial polarisation cues with magnetic field updates to resolve yaw-calibration ambiguities.
Quantum-Aided Gravity Gradient Estimation
Built a deep learning model to estimate vertical gravity gradients from anomaly data, overcoming computational bottlenecks in quantum-aided map-matching navigation.
