Abstract

A system includes a near-infrared (NIR) illuminator, an NIR image sensor, a light detection and ranging (LIDAR) device, and control circuitry configured to perform operations. The operations include causing the NIR illuminator to illuminate a portion of an environment, and obtaining, from the NIR image sensor, NIR image data representing the portion of the environment illuminated by the NIR illuminator. The operations also include detecting a retroreflector within the NIR image data and, based on detecting the retroreflector within the NIR image, determining a position of the retroreflector within the environment. The operations further include, based on the position of the retroreflector within the environment, adjusting at least one parameter of the LIDAR device in connection with scanning the retroreflector.
