Abstract
The present application discloses improvements that can be implemented in a laser detection and ranging (LiDAR) device to achieve accurate obstacle detection and to reduce measurement errors. A LiDAR device uses laser beams to scan a surrounding region to detect and identify objects. In one embodiment, the LiDAR control system is configured to refine a scanning region based on scanning results. The LiDAR control system may divide a scanning region into multiple sub-areas for differentiated scanning efforts. For example, the LiDAR control system may select a sub-area for enhanced scanning, e.g., with increased resolution. Methods for achieving scanning accuracy, increasing signal robustness, and reducing reflective noises are also disclosed.
