Abstract
(EN)
The purpose of the present invention is to acquire road information with high precision regardless of weather or time of day. Provided is a road information sensing device which acquires road information by radiating, upon a road sign which has a plurality of flat surface parts, beams from a transmitting antenna which has variable directionality, said road information sensing device comprising: a transceiver circuit which controls the transmitting antenna so as to scan the beams by switching a radiation angle which includes a directional angle with respect to the frontal direction of a vehicle, and receives as reflected wave signals reflected waves in which the beams are reflected by the plurality of flat surface parts; distance and reflected wave intensity detection units which detect, on the basis of the reflected wave signals, the distances between the vehicle and each of the flat surface parts and the reflected wave intensities of each of the reflected waves which are reflected by each of the flat surface parts; a radiation angle detection unit which detects the radiation angles of the beams on the basis of the reflected wave signals; and a road information analysis unit which creates a heat map on the basis of the radiation angles of the beams, the respective distances, and the reflected wave intensities of the respective reflected waves, and acquires the road information by analyzing the heat map using a threshold value of the reflected wave intensities.
