Overview

Experimental demonstration shows ultra-fast 3D rangefinding in cluttered environments, indicating scalable depth recovery from millimeter to kilometer scales.

Key Points

To develop a high-speed, laser-scanned rangefinding system capable of overcoming frame rate limits and background noise in cluttered environments.
Integrated an event-based vision sensor with a modulated continuous-wave line laser within a Scheimpflug optical arrangement (eSCHORTY).
Processed asynchronous event streams under laser modulation to evaluate feature detection, localization performance, and depth coherence across natural scenes.
Generated dense 3D point clouds at acquisition rates exceeding one million megaevents per second.
Suppressed reflectance-induced centroid artifacts through logarithmic event encoding while balancing feature detection and localization via laser modulation.
Achieved spatially coherent depth reconstruction adaptable across operational ranges from millimeters to kilometers.
