Embodiment 1

[0031] Such as figure 2 As shown, it is the vehicle positioning method and the car-finding method in the parking lot according to Embodiment 1 of the present invention, wherein the vehicle positioning method in the parking lot includes steps S1 to S3, and the car-finding method in the parking lot also includes steps S4 to S5; details as follows:

[0032] Step S1: Before the car enters the parking lot, the navigation software in the mobile terminal realizes high-precision position positioning and vehicle speed measurement through GPS. After the car enters the parking lot, the GPS function will be invalid, so use the navigation software to record the position A before entering the parking lot , so that the location A is automatically triggered to record at the moment when the GPS signal disappears; if the navigation software fails to record the location A, the user can also manually input the location A according to the nearby signs, and use the location A as the starting point...

Embodiment 2

[0044] Such as image 3As shown, it is the vehicle positioning method and the car finding method in the parking lot according to the second embodiment of the present invention, wherein steps S1 to S3 are the same as those in the first embodiment, and will not be repeated here. In step S4', when looking for a car, the mobile terminal does not mark the position C outside the parking lot, and there is no parking space label in the parking lot, so the input position C cannot be determined, and the current position C cannot be manually input and confirmed. At this time, a geometric method can be used, that is: let the user find a lane in the parking lot nearby, stand on the edge of the lane, shoot at the horizon at one end of the lane, then turn around on the spot, and shoot at the other end of the lane , the software can calculate the length of the lane and the position of the user on the lane according to the angle of the two shots and the height of the person, and realize the po...

Embodiment 3

[0048] like Figure 5 Shown is the method for locating a vehicle in a parking lot and the method for finding a car according to Embodiment 3 of the present invention, wherein steps S1 to S3 are the same as those in Embodiment 1, and will not be repeated here. In step S4″, the sweeping method is adopted when looking for a car, that is, the user utilizes the camera to scan the surrounding environment, and then the software realizes positioning of the user’s current position C through image recognition, wherein the sweeping method needs to be installed on the mobile phone in advance. There is a three-dimensional scene map of the parking lot. After the mobile terminal has a built-in three-dimensional scene map of the parking lot, the mobile terminal compares the image of the surrounding environment captured by the camera with the data in the three-dimensional scene map, and detects that the user is currently passing The position of the surrounding environment captured by the camer...

Abstract

The invention discloses a vehicle positioning method and a vehicle finding method in a parking lot. The vehicle positioning method comprises the following steps: acquiring the position of the entrance of the parking lot through a GPS of a mobile terminal before a vehicle enters the parking lot; after the vehicle enters the parking lot, acquiring the traveling track of the vehicle through an inertia measurement device of the mobile terminal; when detecting the advancing state changes from a travelling stage to a walking stage, by using the inertia measurement device of the mobile terminal after the vehicle is parked,, at the moment, calculating the parking position according to the position of the entrance of the parking lot and the traveling track through the mobile terminal, and recording the parking position. The vehicle finding method in the parking lot comprises the vehicle positioning method as well as the following steps: when a user finds the vehicle, acquiring the present position of the user through the GPS and/or manual input through the mobile terminal; generating a vehicle finding route from the present position of the user to the parking position through the mobile terminal, and guiding the user to find the parking position according to the vehicle finding route. The vehicle positioning method and the vehicle finding method in the parking lot are low in cost, high in practicability, high in feasibility and easy to popularize.

Description

technical field [0001] The invention relates to a vehicle positioning method and a vehicle finding method in a parking lot. Background technique [0002] With the progress of society and the development of science and technology, more and more large-scale parking lots have emerged in cities, especially supporting parking lots for large shopping malls, shopping centers, convention centers, and airports. Because these parking lots have large spaces and difficult directions At the same time, most of the parking staff only occasionally park in these public places and are not familiar with the on-site environment. They often forget the parking location of the vehicle when they return to pick up the car after parking, and the search for the car takes a long time and is inefficient. [0003] In response to the above problems, there are currently existing parking lots that try to solve this problem by using card reader positioning, two-dimensional code or barcode positioning, and li...
