Abstract

The invention relates to the technical field of safe driving of automobiles, and discloses a driving recording method and system for identifying the change of a traffic sign board. The method comprises the following steps: S11, acquiring driving information of a vehicle and an image of the first traffic signboard; S12, obtaining information of the first traffic sign board according to the drivinginformation and the image; S13, comparing the information of the first traffic signboard with the information of the second traffic signboard at the same position; S14, if the information of the firsttraffic signboard is different from the information of the second traffic signboard, updating the information of the second traffic signboard to the information of the first traffic signboard, and prompting a driver. According to the driving recording method for identifying the change of the traffic sign board, in the same driving direction of the same road section, once the information of the first traffic sign board is different from the information of the second traffic sign board, the information can be updated in time, and a driver is prompted to pay attention to the change of the traffic sign board.

Description

technical field [0001] The invention relates to the technical field of safe driving of automobiles, in particular to a driving recording system and method for identifying changes in traffic signs.
