SEpi-3D: soft epipolar 3D shape measurement with an event camera for multipath elimination

SEpi-3D: soft epipolar 3D shape measurement with an event camera for multipath elimination

In this paper, we propose the soft epipolar 3D(SEpi-3D) method to eliminate multipath in temporal space with an event camera and a laser projector. Specifically, we align the projector and event camera row onto the same epipolar plane with stereo rectification; we capture event flow synchronized with the projector frame to construct a mapping relationship between event timestamp and projector pixel.

Automotive Object Detection via Learning Sparse Events by Spiking Neurons

Automotive Object Detection via Learning Sparse Events by Spiking Neurons

This paper explores the unique membrane potential dynamics of SNNs and their ability to modulate sparse events. We introduce an innovative spike-triggered adaptive threshold mechanism designed for stable training. Building on these insights, we present a specialized spiking feature pyramid network (SpikeFPN) optimized for automotive event-based object detection.

Event-based Motion-Robust Accurate Shape Estimation for Mixed Reflectance Scenes

Event-based Motion-Robust Accurate Shape Estimation for Mixed Reflectance Scenes

In this paper, we present a novel event-based structured light system that enables fast 3D imaging of mixed reflectance scenes with high accuracy. On the captured events, we use epipolar constraints that intrinsically enable decomposing the measured reflections into diffuse, two-bounce specular, and other multi-bounce reflections.
