Abstract

The invention provides a multi-mode co-location system and method for an intelligent vehicle. The method comprises the steps of collecting road images and scene images of a vehicle travel section, andacquires GNSS position information; if the GNSS position information is received, taking the GNSS position information as positioning information; if the GNSS position information is not received, checking whether the vehicle travel section pre-establishes a visual map database, and if not, using a visual odometer-based vehicle positioning technology to perform position acquisition according to the collected road images; and if so, performing location acquisition by the vehicle positioning technology constructed based on the visual map database according to the collected scene images; or merging the location information obtained by the vehicle positioning technology based on the visual map database and the vehicle positioning technology based on the visual odometer. The invention combinesthree positioning technologies, which can well solve the problem that the GNSS blind zone cannot obtain the positioning information.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, in particular to the field of intelligent perception and service of intelligent transportation position information, and relates to a multi-mode cooperative positioning system and method for an intelligent vehicle and an intelligent vehicle. Background technique [0002] In recent years, cars have become an indispensable part of people's lives. However, with the rapid growth of car ownership, road traffic capacity is gradually saturated, which brings a series of problems while greatly facilitating human life, such as Traffic accidents, road jams, etc. The emergence of the concept of Intelligent Transportation System (Intelligent Transportation System, ITS) provides a new idea for solving the above problems. It effectively integrates advanced information, data transmission, electronic sensing, control and computer technologies for the entire ground transportation. It is a real-time, accu...
