Abstract: A detection system and method for detecting debris in a workspace comprising a grid formed by a first set of tracks extending in a first direction and a second set of tracks extending in a second direction transverse to the first direction. The method involves obtaining image data, representative of an image of at least part of the workspace, and processing it with an object detection model trained to detect instances of debris on the grid. It is determined, based on the processing, whether the image includes debris on the grid. Annotation data, indicative of the debris in the image, is output in response to determining that the image includes debris on the grid.
