Abstract

The present invention provides a traffic sign determination device (100) capable of determining a final traffic sign for a longer time period. A traffic sign determination device includes: an image recognition section (14) which detects a first traffic regulation sign by performing an image recognition process on an image of an area in front of a vehicle picked up by an imaging section (12) provided on the vehicle; a map information acquisition section (24) which, using a position of the vehicle, acquires a road link, including a second traffic regulation sign at the position of the vehicle, from a map data storage section storing map data that includes road link information related to roads; and a traffic sign determination section (32) which, upon detection of a current first traffic regulation sign on a current road link, determines, until the vehicle passes an end point of the current road link, that a current traffic regulation sign to be notified to an occupant of the vehicle is the current first traffic regulation sign detected on the current road link.

Description

technical field [0001] The present invention relates to a road sign judging device for judging (determining) a road sign for notification to a driver using both a road sign (traffic sign) obtained from a captured image and a road sign obtained from map information (Finalized Road Signs, Final Road Signs). Background technique [0002] For example, a speed limit value reporting device is disclosed in the accompanying drawings of Patent Document 1. In the processing performed by the speed limit value reporting device, road signs (information) detected according to images captured by the vehicle-mounted camera and Both road signs (information) obtained from the map data stored in the map data storage section. [0003] However, with the speed limit notification device of Patent Document 1, when the road sign obtained from the captured image does not match the road sign obtained from the map data, the final road sign cannot be notified to the occupant. In other words, in the sp...
