Abstract

Provided are an autonomous driving assistance device and an autonomous driving assistance system capable of determining whether or not a specific area is usable. The autonomous driving assistance device includes: an object detection unit which detects an object from monitoring data of a specific area; a position calculation unit which calculates a position, in the real world, of the object detected by the object detection unit; a map information acquisition unit which acquires a position, in the real world, of the specific area; a determination unit which determines, by using the position of the object calculated by the position calculation unit and the position of the specific area acquired from the map information acquisition unit, whether or not the specific area is usable; and an output unit which outputs a result, of the determination performed by the determination unit, indicating whether or not the specific area is usable.
