Abstract

The embodiment of the invention discloses a traffic sign transmitting end and a traffic sign recognition system. The traffic sign transmitting end comprises a processing module, a data storage module and a wireless transmitting module, wherein the data storage module is used for storing identity information of a traffic sign related to the traffic sign transmitting end; the wireless transmitting module is used for transmitting the identity information to the surrounding environment in a wireless mode; and the processing module is used for reading the identity information stored in the data storage module and controlling the wireless transmitting module to transmit the identity information. According to the technical scheme of the invention, through building the traffic sign recognition system comprising a general control end, the traffic sign transmitting end and a traffic sign receiving end, the technical effect that the traffic sign receiving end acquires the sign content through receiving the identity information of the traffic sign can be realized, the problem of low recognition rate of the traffic sign recognition technology based on image recognition is solved, and the traffic sign recognition accuracy is improved.

Description

technical field [0001] Embodiments of the present invention relate to information recognition technology, and in particular to a traffic sign sending terminal and a traffic sign recognition system. Background technique [0002] With the development of society, cars have become an irreplaceable means of transportation for human daily life. However, it is accompanied by increasingly prominent security problems. Correspondingly, unmanned driving technology came into being. With the continuous development of unmanned driving technology, unmanned vehicles will play an increasingly important role in people's lives. In order to be able to safely and reliably drive unmanned vehicles on the road, it is necessary to be able to accurately obtain the sign content of the traffic markers placed on the driving route, and adopt the corresponding automatic driving strategy according to the acquired sign content of the traffic markers . [0003] At present, existing unmanned vehicles main...
