Intelligent vehicle map fusion system and method based on roadside equipment

Abstract

The invention relates to a system and a method for intelligent vehicle map merging based on road side equipment. The system comprises vehicle-mounted equipment and the road side equipment, wherein the vehicle-mounted equipment comprises a vehicle positioning module, an ADAS (automatic data acquisition system) map interface, a local map generation module, a DSRC (dedicated short range communication) communication module and a map conversion module; the road side equipment comprises a DSRC communication module and a map merging module; the vehicle positioning module of the vehicle-mounted equipment is used for detecting the position and attitude of a main vehicle; the ADAS map interface module is used for providing Id (identification) information of a road; the local map generation module is used for generating a local map of the current position of the main vehicle; the DSRC communication module is used for realizing the interaction between the vehicle and the road side equipment; the map conversion module is used for converting a merged map into a coordinate system of the main vehicle; the map merging module of the road side equipment is used for converting the local map of each vehicle received by the DSRC communication module into the coordinate system of the road side equipment, and merging. The system has the advantages that the sensing abilities of multiple vehicles are shared to widen the environment sensing range, and the assisted driving / automatic driving property of the intelligent vehicle is improved.

Description

technical field [0001] The invention belongs to the technical fields of automation, communication and computer, and in particular relates to an intelligent vehicle map fusion system and method based on roadside equipment. Background technique [0002] Environmental perception and map generation are one of the key technologies of intelligent vehicles. In order to improve the performance of intelligent vehicle assisted driving safety warning and automatic driving path planning, intelligent vehicles need to have as large a range of environmental perception as possible. However, traditional methods generally only rely on vehicle The on-board sensor itself makes the vehicle's perception ability extremely limited. [0003] Chinese patent application: An intelligent navigation system (application number: CN200710064151.3) discloses a method that uses the server to send real-time traffic information to the vehicle client to plan the route for the user. The method uses the network to...
