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...

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.

Example Embodiment

[0066] Example 1
[0067] Car positioning system, including:
[0068] The vehicle-mounted intelligent system includes a parking space information acquisition device, a vehicle identification system, a vehicle communication module, a visual odometer, and an inertial navigation system. The parking space information acquisition device is used to collect parking space characteristic image information; the parking space information acquisition device selects a vehicle-mounted camera, preferably Surround view cameras (front-view cameras are also available) collect parking number information. For example, the 3DAVM parking system is equipped with four ultra-wide-angle cameras on the body to seamlessly splice the signals captured around the car. The vehicle-mounted identification system is used to identify the characteristic image information of the parking space, and based on the identified parking space information, perform positioning on the parking lot map of the vehicle-mounted intelligent system to form positioning one. The characteristic image includes, but is not limited to, a parking space number image, and may also be other characteristic images that can identify a location, such as parking lot architectural image information, parking lot organization image information, and the like. Image recognition uses segmentation of the parking space number (usually in the yellow area) and recognizes separately, such as through the neural network SVM algorithm. SVM is a new type of machine learning method proposed by Vapnik et al. in the early 1990s. This method can achieve good classification and promotion capabilities with few training samples. The invention applies the SVM algorithm to recognize the characters in the license plate, and the non-character feature extraction improves the recognition speed and can obtain a higher recognition rate. In this process, the method of eigenvalue square graph is used to match and confirm the number. The visual odometer and the inertial navigation system position the vehicle to form positioning two. The positioning 1 and positioning 2 are fused to form accurate position information of the vehicle; the visual odometer and inertial navigation system for positioning and fusion technology of the vehicle are the same as the patent document of the application publication number CN102538781A. The vehicle-mounted communication module is used to send the location information on the parking lot map of the vehicle-mounted intelligent system to the mobile terminal.
[0069] Automatically locate the parking position when parking, without manual intervention. Avoid that the user forgets to operate when parking, and there is no "vehicle positioning information" data when looking for a car, which makes it impossible to realize the car. The user cannot determine whether he will forget the location information of the car when parking, and he does not need manual intervention to avoid forgetting operations. At the same time, in the case that the parking position can be memorized, the intervention of early manual positioning is avoided.
[0070] The mobile terminal includes a user location information collection device, a mobile identification system, a display device, and a mobile communication module; the user location information collection device is used to collect characteristic image information of the user's location; the mobile communication module is used to receive information sent by the vehicle communication module Parking space location information; the mobile recognition system is used to identify the characteristic image information of the user's location, and locate the user's location on the parking lot map of the mobile terminal after identifying the feature value; according to the two already located on the parking lot map Location, route planning, and display through the display device to achieve accurate car finding.
[0071] The mobile terminal is a mobile phone, the mobile phone is installed with a positioning APP, the positioning APP calls the mobile phone camera to collect the characteristic image information of the user's location; the positioning APP calls the mobile phone communication module to receive the parking space characteristic image information sent by the vehicle communication module, and locate The APP recognition system recognizes the characteristic image information of the parking space and the characteristic image information of the location of the user, locates the location of the vehicle and the user on the parking lot map, and the positioning APP performs path planning according to the two locations that have been located on the parking lot map , The positioning APP displays the planned route through the mobile phone display device.
