Parking-lot-vehicle cooperative intelligent parking system and method based on centralized vision

Abstract

The invention relates to a parking-lot-vehicle cooperative intelligent parking system and method based on centralized vision. The system comprises a parking lot service center, an intelligent vehicle onboard device and a user mobile terminal. The parking lot service center includes a visual sensor group, a vehicle tracking module, a path planning module, a data management module and a communication module. The observation range of the visual sensor group covers all the traffic areas in a parking lot. The vehicle tracking module fuses the images collected by the visual sensor group and detects the position and the attitude of a vehicle target in the traffic area. The path planning module plans a driving route according to the current position and the attitude of the vehicle and parking stalls. The onboard device includes a communication module and a vehicle control module. The vehicle control module receives the path planned by the service center and controls the vehicle to automatically drive to the end along the path. The user mobile terminal is used to issue the request information for entering/leaving the parking lot to the parking lot service center. The parking-lot-vehicle cooperative intelligent parking system and method realize automation and intellectualization of going into or out of the parking lot.

Description

technical field [0001] The invention belongs to the field of intelligent transportation and automatic control, in particular to an intelligent parking system and method based on centralized vision-based parking lot-vehicle coordination. Background technique [0002] Traditional parking lots only realize basic service functions such as hourly charging, parking space inquiry, and license plate recognition, and the level of automation and intelligence is not high. Compared with outdoor parking lots, indoor parking lots often have the characteristics of complex environment, narrow roads, and limited vision, which make it more troublesome for vehicles to find vacant parking spaces when driving in and to find vehicles when driving out. In addition, the current solutions to the parking problem of intelligent vehicles usually only focus on a single intelligent vehicle itself, which makes the intelligent vehicle's ability to perceive the overall situation of the parking lot limited, ...

Problems solved by technology

Chinese patent application: An intelligent vehicle automatic driving system and method coordinated with an intelligent parking lot (application number: 201610107483.4) discloses an intelligent vehicle automatic driving system and method coordinated with an intelligent parking lot, which realizes the vehicle and parking Collaboration between fields, but the background service system only performs location allocation and map transmission, while environment detection and path planning are performed by vehicles, relying on the support of on-board sensors

This method adopts a distributed structure, and each visual sensor requires a local tracker module, and the cost will be relatively high when the number of visual sensors is large
