Parking lot navigation system and method based on machine vision

Abstract

The invention requests a parking lot navigation system and method based on machine vision. The system is formed by a parking lot service center and a user mobile terminal on a vehicle. The parking lot service center comprises a vehicle tracking module, a data management module and a communication module, wherein the vehicle tracking module is formed by multiple groups of vision sensors which are installed in a parking lot and has an observation range which covers all passing and parking areas in the parking lot, local tracker corresponding to the vision sensors and a global tracker and is used for detecting an occupation state of each parking space and the movement state of a vehicle target of a parking lot passing area in real time. The user terminal comprises a navigation module and a communication module, the navigation module plans a vehicle driving path to carry out navigation according to a local vehicle position, free parking spaces and a parking lot real-time map from the parking lot service center received by the communication module. According to the system and the method, the intelligence of vehicle navigation in the parking lot is realized, and the parking efficiency and convenience in the parking lot are improved.

Description

technical field [0001] The invention belongs to computer and automation technology, in particular to the technical field of Internet of Vehicles and vehicle navigation, and in particular relates to a parking lot navigation system and method based on machine vision. Background technique [0002] As the scale and complexity of the parking lot increase, especially the indoor parking lot, there are often narrow roads, complex environments, and poor vision, which makes it more troublesome for drivers to find a free parking space in the parking lot or drive out of the parking lot. . In addition, the existing parking lot system can only provide the number or number of vacant parking spaces, and cannot provide intuitive navigation and real-time maps to guide vehicles, so that it cannot provide higher-quality parking services, and there is no effective communication between the parking lot and the vehicle. The level of collaboration, automation and intelligence is not high. [0003...

Problems solved by technology

[0002] As the scale and complexity of the parking lot increase, especially the indoor parking lot, there are often narrow roads, complex environments, and poor vision, which makes it more troublesome for drivers to find a free parking space in the parking lot or drive out of the parking lot.

In addition, the existing parking lot system can only provide the number or number of vacant parking spaces, and cannot provide intuitive navigation and real-time maps to guide vehicles, so that it cannot provide higher-quality parking services, and there is no effective communication between the parking lot and the vehicle. Collaboration, low level of automation and intelligence

[0003] Chinese patent application: A parking lot intelligent management server, system, method and UWB positioning tag (application number: 201610875430.7) discloses a parking lot intelligent management system and method based on UWB positioning, the system uses the UWB positioning method to guide the needs Real-time positioning of the location of the vehicle can realize the navigation of the vehicle in the parking lot to the free parking space, but this method cannot independently realize the detection of the idle state of the parking space

[0004] 201610811935.7) discloses a parking lot navigation method based on pressure sensors and GPS positioning. The system uses pressure sensors to determine the idle state of parking spaces, uses GPS to locate the implementation position of vehicles, and can realize the vehicle in the parking lot to the vacant parking space. navigation, but not for indoor parking

Chinese patent application: Parking lot-vehicle collaborative intelligent parking system and method based on distributed vision (application number: 201610228232.1) discloses a parking lot-vehicle collaborative intelligent parking system and method based on distributed vision. The parking lot service center covers the parking lot area with distributed vision sensors to detect the target movement status and obstacles. The parking lot service center plans a route and sends it to the smart vehicle. The vehicle control module of the smart car controls the vehicle to complete the automatic driving in the parking lot. but not suitable for vehicles driven by persons
