Parking position visual navigation system based on indoor precise real-time localization

Abstract

The invention discloses a parking position visual navigation system based on indoor precise real-time localization, comprising an indoor precise real-time localization system, an indoor wireless communication system, a navigator and a parking lot management server. An automobile driver receives a hand-hold navigator when entering a parking lot or directly enters the parking lot by using an onboard navigator; the indoor precise real-time localization system determines the precise position of the driver according to a localization label arranged in the navigator and transmits the precise position to the parking lot management server by the indoor wireless communication system; the parking lot management server determines the optimal parking position according to the position of the driver and the vacancy situation of the parking lot, and then the optimal parking position navigating route is transmitted to the navigator by the indoor communicating system and is displayed on the screen of the navigator. The invention does not need to install a parking position detector at each parking position and can carry out precise visual navigation on the parking position, thereby ensuring that a parker can quickly and accurately find the parking position. The invention is especially suitable for the management of large-sized parking lots.

Description

technical field [0001] The invention relates to the technical field of parking space navigation detection, in particular to a parking space visual navigation system based on indoor accurate real-time positioning. Background technique [0002] The existing parking space management method needs to install parking space detectors such as ultrasonic, light or pressure sensors on each parking space in the parking lot to check the usage of the parking space, and it is impossible to actually visually navigate the parking route in the parking lot. An existing patent application document with a publication number of CN101403617A discloses a GPS-based intelligent parking navigation system. The system configures a parking space detector in each parking space, and stores the latitude and longitude of each parking space in the parking lot management server. Information, used to detect whether the parking space is used and send the result to the parking lot management server. When the dr...

AI Technical Summary

Problems solved by technology

This invention needs to install a parking space detector in each parking space, and use GPS to navigate after obtaining the latitude and longitude of the nearest parking space. GPS is a widely used outdoor positioning technology, but the positioning accuracy of civilian GPS is low, which is beyond the reach of civilian GPS. The positioning accuracy ranges from 5 meters to 20 meters, and the parking spaces in the parking lot are generally narrow and the driving routes are tight. The positioning accuracy of GPS will not meet these requirements

Therefore, in fact, this invention can only use the car GPS navigation device to navigate the general orientation of the parking lot, and cannot really perform accurate visual navigation on the parking route in the parking lot.
