Abstract: In a displacement monitoring method based on elliptical trajectory calibration and modified principal component analysis, four channels are compressed into two set signals through linear combination to solve null point issue in Doppler radar and cancel clutter effect. The two sets linear combined signals make two tilted elliptical trajectories which can be calibrated for DC offset, amplitude imbalance and phase imbalance using simple computation. Due to the elliptical trajectories are mirror symmetric tilt ellipses, the residual clutter can be cancelled to recover a clear Doppler phase after demodulation and combination.

Abstract: In various examples, a 3D surface structure such as the 3D surface structure of a road (3D road surface) may be observed and estimated to generate a 3D point cloud or other representation of the 3D surface structure. Since the estimated representation may be sparse, a deep neural network (DNN) may be used to predict values for a dense representation of the 3D surface structure from the sparse representation. For example, a sparse 3D point cloud may be projected to form a sparse projection image (e.g., a sparse 2D height map), which may be fed into the DNN to predict a dense projection image (e.g., a dense 2D height map). The predicted dense representation of the 3D surface structure may be provided to an autonomous vehicle drive stack to enable safe and comfortable planning and control of the autonomous vehicle.
