Method and device for carrying out vehicle positioning in parking lot

Abstract

The invention relates to a method and device for carrying out the vehicle positioning in a parking lot. The method is used for a server, and comprises the steps: obtaining the actual receiving signal intensity indication information of an intelligent terminal at a current position and an instant scene image when a server communicates with the intelligent terminal on a vehicle entering the parking lot; determining a pre-stored scene image corresponding to the actual receiving signal intensity indication information according to the actual receiving signal intensity indication information and a pre-built position fingerprint map of the parking lot; and determining the current actual position of the vehicle in the parking lot according to the pre-stored scene image and the instant scene image. Therefore, the method can achieve the positioning of the vehicle in the parking lot without other operation and maintenance equipment in the parking lot, and reduces the positioning cost. In addition, even if a GPS signal is weak or there is no GPS signal, the method also can achieve the high-precision positioning, is short in positioning time, and improves the parking experience of a user.

Description

technical field [0001] The present disclosure relates to the field of Internet of Vehicles, and in particular to a method and device for positioning a vehicle in a parking lot. Background technique [0002] With the rapid development of Internet technology and the improvement of people's living standards, smart terminals have become an indispensable communication, entertainment and social tool in people's daily life. The wireless local area network (WLAN) based on the IEEE802.11 standard has the characteristics of flexibility, mobility, convenient installation, and easy expansion, which make the application of intelligent terminals by means of the wireless local area network more and more extensive. Wireless local area network positioning has become a widely used technology in indoor positioning technology due to its advantages such as good economy, convenient use, and wide coverage. The WiFi-based indoor positioning technology determines the location information of the tar...

Problems solved by technology

[0003] When the vehicle enters the indoor parking lot, the GPS signal is extremely weak or even disappears, and the owner cannot use GPS for positioning in the indoor environment

In recent years, in shopping malls, shopping centers and other large parking lots, it takes time to find a parking space, which is a very troublesome problem for car owners.

In addition, due to the large space in the parking lot, the similar environment and landmarks, and the difficulty in identifying the direction, car owners tend to get lost in the parking lot and find their vehicles difficult.
