Abstract:
System, methods, and other embodiments described herein relate to improving observations of a surrounding environment using a light detection and ranging (LiDAR) device in the presence of highly reflective surfaces. In one embodiment, a method includes, in response to determining that a first point cloud includes an observation of an obscuring object that is highly reflective: i) emitting a scanning light beam at a scanning intensity that is different from an initial intensity of an initial light beam used to acquire the first point cloud, and ii) dynamically controlling the LiDAR device to acquire a second point cloud that omits the obscuring object. The method includes generating a composite point cloud from the first point cloud and the second point cloud that improves an observation of the surrounding environment using the LiDAR device by mitigating interference from the obscuring object.
