Abstract
A ground-classifier system that classifies ground-cover proximate to an automated vehicle includes a lidar, a camera, and a controller. The lidar that detects a point-cloud of a field-of-view. The camera that renders an image of the field-of-view. The controller is configured to define a lidar-grid that segregates the point-cloud into an array of patches, and define a camera-grid that segregates the image into an array of cells. The point-cloud and the image are aligned such that a patch is aligned with a cell. A patch is determined to be ground when the height is less than a height-threshold. The controller is configured to determine a lidar-characteristic of cloud-points within the patch, determine a camera-characteristic of pixels within the cell, and determine a classification of the patch when the patch is determined to be ground, wherein the classification of the patch is determined based on the lidar-characteristic and the camera-characteristic.
