Problems solved by technology

[0002] Parking lots are indispensable in the era of automobiles. For example, new high-rise buildings will incorporate underground parking lots into the necessary supporting facilities. Large-scale, three-dimensional parking lots are like a maze, which brings a new problem: it is difficult to find a car.
Although this type of system does not need to use the GPS positioning system to locate and find the car, this type of system needs to artificially "obtain (referring to obtain through technical means, such as the above-mentioned acquisition through the reading unit)" the scene identification of the parking space when parking, otherwise it cannot Obtain parking space information, causing users to be unable to find parking spaces
However, the user cannot be sure whether he will forget the location information of the car when parking. Even if he can remember the parking space information, since he cannot accurately know whether he can remember the parking space when parking, he also needs to “check” the parking space when parking. Get"; when you forget to "get" the scene identification of the parking space during the parking process, you will not be able to find the parking space

Embodiment 1

[0067] Positioning and car finding system, including:

[0068] The vehicle-mounted intelligent system comprises a parking space information collection device, a vehicle identification system, a vehicle-mounted communication module, a visual odometer and an inertial navigation system, and the parking space information collection device is used to collect parking space feature image information; the parking space information collection device selects a vehicle-mounted camera, preferably The surround view camera (the front view camera can also be used) collects the parking space number information. For example, if the 3DAVM parking system is adopted, the signals captured around the car can be seamlessly spliced ​​by carrying four ultra-wide-angle cameras on the body. The on-board recognition system is used to identify the characteristic image information of the parking space, and according to the identified parking space information, locate on the parking lot map of the on-board i...

Embodiment 2

[0086] Scheme is identical with embodiment 1, as figure 1 As shown, the difference:

[0087] Position the vehicle:

[0088] (1) After the vehicle arrives at the garage and parks in the parking space, the parking space feature image information is collected through the parking space information collection device of the vehicle intelligent system;

[0089] (2) The on-board recognition system of the on-board intelligent system recognizes the characteristic image information of the parking space;

[0090] (3) according to the characteristic image information of the parking space identified, positioning is carried out on the parking lot map of the vehicle-mounted intelligent system to form a positioning one;

[0091] (4) Position the vehicle where the vehicle is parked through the visual odometer combined with the inertial navigation system to form a positioning 2;

[0092] (5) Fusion the two positions of positioning 1 and positioning 2 to obtain accurate vehicle positioning inf...

Embodiment 3

[0100] The relevant technical principles involved are the same as in Embodiment 1, and the specific scheme:

[0101] Position the vehicle:

[0102] (1) The mobile terminal locates the vehicle through the visual odometer combined with the inertial navigation system to form a vehicle positioning system;

[0103] (2) The mobile terminal uses the information collection device to collect the characteristic image information of the location of the vehicle;

[0104] (3) The mobile terminal identification system identifies the characteristic image information of the location of the vehicle;

[0105] (4) Positioning on the map according to the characteristic image information of the vehicle location identified by the mobile terminal to form a vehicle location 2;

[0106] (5) The mobile terminal fuses the two positions of vehicle positioning 1 and vehicle positioning 2 to obtain accurate vehicle positioning information;

[0107] Locate the user's location when looking for a car:

Abstract

The invention discloses a positioning and vehicle searching system, a positioning and vehicle searching method and a location positioning method. The positioning system includes a vehicle-mounted intelligent system and a mobile terminal. After a vehicle arrives at a garage and parks in a parking space; the vehicle-mounted intelligent system acquires parking space number information; the vehicle-mounted intelligent system performs positioning on a parking lot map according to identified parking lot information; a user compares the characteristic value of his or her location with the parking lot map through the mobile terminal, so that the characteristic value can be identified, and therefore, the current location of the user can be positioned; and path planning is performed according to two positioned points in the parking lot map, and therefore, accurate vehicle searching can be realized.

Description

technical field [0001] The invention relates to a system for positioning and finding a car, in particular to a system for positioning and finding a car when there is no GPS signal or the GPS signal is poor. The invention also relates to a method for locating and finding a car and a method for position locating. Background technique [0002] Parking lots are indispensable in the automobile era. For example, new high-rise buildings have incorporated underground parking lots into the necessary supporting facilities. Large-scale, three-dimensional parking lots are like a maze, which brings a new problem: it is difficult to find a car. In the huge parking lot, it takes a lot of work to find your car accurately. Even if you have recorded your parking space, when you come back to find your car, it will be quite laborious to find your car in the complex underground parking garage. [0003] For the current difficult problem of finding a car, the existing methods for eliminating the...
