METHODS AND SYSTEMS FOR DETECTING SENSOR OCCLUSIONS

Document Type and Number:

WIPO Patent Application WO/2020/162994

Kind Code:

A3

Abstract:

One example method involves rotating a housing of a light detection and ranging (LIDAR) device about a first axis. The housing includes a first optical window and a second optical window. The method also involves transmitting a first plurality of light pulses through the first optical window to obtain a first scan of a field-of-view (FOV) of the LIDAR device. The method also involves transmitting a second plurality of light pulses through the second optical window to obtain a second scan of the FOV. The method also involves identifying, based on the first scan and the second scan, a portion of the FOV that is at least partially occluded by an occlusion.
