METHOD AND SYSTEM FOR A THRESHOLD NOISE FILTER

An example method and system for filtering point cloud data includes obtaining point cloud data from a LIDAR device. The point cloud data may include at least a first pulse-length range and a second pulse-length range. The first range may include one or more first-length pulses and the second range...

Beschreibung
Zusammenfassung:	An example method and system for filtering point cloud data includes obtaining point cloud data from a LIDAR device. The point cloud data may include at least a first pulse-length range and a second pulse-length range. The first range may include one or more first-length pulses and the second range may include one or more second-length pulses. The method may further include filtering the point cloud data by determining respective magnitudes of each of the one or more first-length pulses and each of the one or more second-length pulses, comparing the magnitudes of the first-length pulses to a first threshold, comparing the magnitudes of the second-length pulses to a second threshold, and removing any pulses having a magnitude less than the respective thresholds. The method may further include determining, based on the filtered point cloud data, objects in an environment around the LIDAR.
