Abstract: A sign recognition system according to an exemplary aspect of the present disclosure is configured to, when image data of a sign is captured by a vehicular camera, recognize one or more characters, which are included in the sign and belong to at least one specified character type, from the image data, thus extracting, from the image data, the recognized one or more characters. The sign recognition system is also configured to store a sign dataset in a sign database; the sign dataset includes (i) an installation-position information item indicative of the installation position of the sign, and (ii) an attribute information item about the sign.
