Abstract
A light detection and ranging (lidar) device may be coupled to a vehicle and configured to scan a surrounding environment to determine ranges to one or more objects in the surrounding environment of the vehicle. The lidar device may generate data that can be used to form a range image, which includes or is based on range data determined for the one or more objects. The lidar device may also generate data that can be used to form a corresponding background image, which includes background light intensity data that the lidar device measures during the scan. The background image or background image data may be used to add range data to the range image, correct range data in the range image, and/or evaluate the quality of the range data in the range image. In this way, the background image or background image data can be used to generate an enhanced range image that includes range data that is more comprehensive and/or more reliable than the range data included in the original range image.
