  "abstract": "A method for indoor operation monitoring of a cleaning device is provided, which is executed by a server of a system for indoor operation monitoring of a cleaning device. The method includes generating a work region map; forming a monitoring map based on location fingerprints taken from a work region in the work region map; determining working trajectory points of the cleaning device based on a set of positioning data; obtaining a monitoring task region through a monitoring terminal; determining, based on the monitoring map, a monitoring region map corresponding to the monitoring task region, matching the working trajectory points with the monitoring region map, and determining cumulative trajectory points within the monitoring task region; and in response to determining that a count of the cumulative trajectory points and distribution situation of the cumulative trajectory points satisfy a preset update condition, sending a display update instruction to the monitoring terminal.",
