Abstract

The present invention provides a multi-mode collaborative positioning system and method for smart vehicles, which collects road surface images and scene images of vehicle driving sections, and obtains GNSS position information; if the GNSS position information is received, the GNSS position information is used as the positioning information; if the GNSS position information is not received For GNSS position information, check whether the visual map database is pre-established on the road section of the vehicle. If not, use the vehicle positioning technology based on the visual odometer to obtain the position according to the collected road surface image; if yes, use the vehicle positioning technology based on the collected scene image. The vehicle positioning technology based on the visual map database is used for position acquisition; or, the vehicle positioning technology based on the visual map database and the position information obtained by the vehicle positioning technology based on the visual odometer are fused. The invention integrates three positioning technologies, and can well solve the problem that positioning information cannot be obtained in GNSS blind areas.

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...
