Abstract
Embodiments of the present application disclose an abnormal area marking method and a related apparatus. The method includes: when a predicament is detected during an operation process, determining an area of a current position as an abnormal area; obtaining a sensing data set within a specified time period during the operation process, where the sensing data set is a set of data acquired by a sensor, and the specified time period represents a safe traveling time period before the robotic lawn mower gets into the predicament; determining abnormality description information of the abnormal area based on the sensing data set; and determining a target position corresponding to the abnormal area on an operation map, and establishing an association relationship between the target position and the abnormality description information.
