Abstract

The invention relates to a traffic sign identification method and system for unmanned driving and traditional driving. The method comprises: a wireless signal emission apparatus installed at a traffic crossing modulating real time sign signals into frequency modulation signals, and sending corresponding frequency modulation signals; and a vehicle wireless signal receiver on an unmanned driving vehicle receiving, modulating and analyzing the frequency modulation signals, and sending analyzed sign singles to the unmanned driving vehicle. The traffic sign identification method can effectively, reliably and real-timely detect and identify traffic signs, accurately identify traffic crossing signal lamp information, meet requirements of unmanned driving and traditional driving, and improve driving safety.

Description

technical field [0001] The invention belongs to the field of unmanned vehicles, and relates to a traffic sign recognition method and system for unmanned and traditional driving. Background technique [0002] At present, unmanned driving technology is being widely concerned and sought after by various countries and automobile manufacturers with unprecedented speed and attention. The mixed operation state of unmanned vehicles and traditional driving vehicles. Traffic lights as traffic lights have been well known to traditional traffic participants and have no identification barriers, but they have brought a lot of challenges to emerging traffic participants - unmanned vehicles. The traffic light recognition method in unmanned driving technology is one of the research hotspots in the field of traffic information detection in the intelligent transportation industry. Yuan Jiazheng; Liu Hongzhe et al. proposed a real-time dynamic intersection traffic light detection and recognit...
