Special vehicle identification method for driverless vehicle

Abstract

A special vehicle identification method for a driverless vehicle comprises the following steps: performing multi-channel information acquisition, performing vehicle detection and characteristic extraction, and performing special vehicle identification. According to depth learning, characteristics of a target vehicle are extracted from multi-channel real-time traffic video and audio information, and by virtue of Bayesian statistical learning, multi-modal integrated special vehicle identification is achieved. According to a logo of the special vehicle and unique image characteristics thereof aswell as acousto-optic characteristics of an alarm lamp and an alarm, the special vehicle and the working state thereof can be quickly identified. By the special vehicle identification method for the driverless vehicle, detection and identification of the driverless vehicle on the special vehicle carrying out a task on a road can be achieved, an operating system of the driverless vehicle is promptly notified of taking avoiding measures, and a decision making basis is provided for the driverless vehicle to timely avoid a road participating object with a traffic priority right; according to the special vehicle identification method for the driverless vehicle, the problem of false identification of the special target vehicle can be reduced, so as to improve the intelligent level of the driverless vehicle.

Description

technical field [0001] The invention relates to a special vehicle identification method, in particular to a special vehicle identification method for driverless vehicles. Background technique [0002] my country's road traffic safety law stipulates that special vehicles such as police cars, fire trucks, ambulances and engineering emergency vehicles driving on the road have the right and obligation to display their identity, and are not affected by the driving route, driving direction, driving speed and other special vehicles. Freedom of movement restricted by signal lights, and right of way requiring other vehicles and pedestrians to give way. With the maturity of intelligent transportation and unmanned driving technology, the control system of unmanned vehicles must consider the right of way of special vehicles. [0003] Traditional methods usually install RFID electronic identity devices on vehicles, construct 3D models, vehicle outlines or license plate numbers to identif...
