Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand for those skilled in the art and will therefore make the scope of the invention more clearly defined.
As shown in fig. 1, a parking position information management method according to an embodiment of the present invention includes the steps of:
and S110, calling a vehicle image after the vehicle is judged to be stopped.
The method for acquiring the parking information includes the steps that the parking information is acquired, generally, the parking information can be acquired after a vehicle parks, or the acquired parking information is really required by a user only after the vehicle actually parks, and the vehicle image is required to be called and subsequently analyzed to achieve the purpose of acquiring the parking information.
In one embodiment, when it is recognized that the engine of the vehicle is off, it is determined that the vehicle is stopped. Specifically, when the vehicle key is pulled out, or after the vehicle start/stop button is pressed and the vehicle is turned off, it is determined that the vehicle is stopped.
Of course, the vehicle may be determined to be stopped by the vehicle not performing any driving motion within a preset time, for example, the vehicle may not perform any driving motion within 30 minutes.
In one embodiment, before the vehicle stops, the vehicle image is also collected and stored; this is because the time after the parking is determined is a certain time after the parking, that is, the time may be a time when the vehicle key is removed or a time at the moment when the vehicle start/stop button is pressed and the vehicle is turned off. It can be understood that, after the parking, the vehicle is in the state of not traveling, and the image collection device on the vehicle can only collect the image of this specific state after the vehicle stops, and is difficult or can't be to accurate parking information, go to gather enough and can be used for calculation analysis to obtain this accurate parking information, consequently, need before the vehicle stops, still gather the vehicle image to the required data of parking stall floor level in the parking area that obtains the vehicle place for follow-up calculation analysis is done basic data acquisition work.
Further, after the vehicle is judged to be parked, the vehicle image within the preset time before the vehicle is parked is called, and it can be understood that the time required for parking is generally within a range, and if too many vehicle images unrelated to the parking are called, the calculation amount is inevitably increased, and even the accuracy of the parking position information obtained by analyzing and calculating after the parking is influenced.
In one embodiment, the vehicle image includes a vehicle backing image, a vehicle driving record image and/or a vehicle panoramic image.
Specifically, as shown in fig. 2 and fig. 3, taking a car reverse image as an example for illustration, currently, most cars are equipped with a reverse camera, which is attached to the rear portion of the car and can help the car to detect a blind spot to see the situation behind the car, and when the car is reversed, the reverse camera is automatically turned on, so that during the process of reversing into the parking lot rack, the camera can capture the parking lot parking space number assigned to the car, i.e. the car reverse image contains the parking lot space number assigned to the car, as shown in fig. 2, the parking lot space number assigned to the car is 204, as shown in fig. 3, the parking lot space number 125 assigned to the car.
Further, for a complex floor, for example, a multi-floor parking lot has a complex parking space number assigned to the corresponding vehicle, and generally includes a parking space floor value of the parking lot where the vehicle is located, for example, the vehicle is a 3 rd a area 203 of the parking lot or parking frame, and the parking space number of the parking lot is generally "3-a-203", or for example, the vehicle is a minus 2 rd 425 of the parking lot or parking frame, and the parking space number of the parking lot is generally "-2-425", and thus the parking space number of the parking lot includes the parking space floor value of the parking lot where the vehicle is located.
Furthermore, through more types of vehicle images, the parking lot parking space number including the parking space floor value of the parking lot where the vehicle is located can be obtained through subsequent analysis and calculation by more ways or more data volumes.
In an embodiment, the vehicle backing image, the vehicle driving record image and/or the vehicle panoramic image are further sent, it can be understood that when a user or a parking lot administrator receives the parking lot number including the parking lot floor value of the parking lot where the vehicle is located, the user or the parking lot administrator can find the specific parking lot with difficulty, and by sending the vehicle backing image, the vehicle driving record image and/or the vehicle panoramic image, more references of driving tracks can be provided for the user or the parking lot administrator to verify the parking lot searching path.
Further, the panoramic image of the vehicle in the parking state is sent in real time, so that the specific environmental condition of the vehicle after parking can be better monitored or obtained, the condition of the vehicle can be monitored, or certain reference can be provided for finding the parking space.
And S120, carrying out optical character recognition on the vehicle image to obtain the parking space number of the parking lot containing the parking space floor value of the parking lot where the vehicle is located.
Specifically, an Optical Character Recognition (OCR) technology is used on the vehicle image to obtain the parking space number of the parking lot corresponding to the vehicle in the parking state. Optical Character Recognition (OCR) technology has been used in other areas such as automatic license plate recognition (ANPR), where the system is different from ANPR, where the system is used to identify the assigned number of a parking lot, and it is implemented in the car itself using hardware that is currently available in many vehicles, so it may not be necessary for the car owner to purchase an additional camera for this purpose. The system in the vehicle will automatically process this data and send the results to the APP in the driver's cell phone.
In particular, some vehicles are equipped with multiple cameras and the system should utilize all cameras suitable for increasing the rate of image capture of the designated number of the parking lot. The system will process the data.
Specifically, the system in the vehicle will save a video file of the parking process, but will not automatically send to the APP on the driver's cell phone. The system should save the last n minutes of recorded video before the driver turns off the engine. n is configurable, with a default value of 5 minutes. If the driver needs to obtain more information about the parking environment, the system may be requested to send a video.
And S130, sending the parking space number of the parking lot.
After the parking lot parking space number containing the parking space floor value of the parking lot where the vehicle is located is obtained in step S120, the parking lot parking space number is sent out, for example, the vehicle central control device executing the method step sends the parking lot parking space number to the parking lot, or the vehicle central control device sends the parking lot parking space number to a parking lot or a user intelligent mobile terminal through a server, or the vehicle central control device executes the method step sends the parking lot parking space number to a display screen of the vehicle central control device for visualization or a speaker for playing, and the like, so as to send the parking lot parking space number.
Specifically, the parking lot administrator or the user receives the parking lot parking space number, which means that after receiving the parking lot parking space number including the parking space floor value of the parking lot where the vehicle is located, the parking space floor value of the parking lot where the vehicle is located can be known, and more accurate parking position information can be acquired through the remaining parking position information included in the parking lot parking space number.
In one embodiment, the vehicle running height difference, the vehicle running mileage and the vehicle running time are further collected, and the parking space floor value of the parking lot where the vehicle is located is calculated.
Specifically, the vehicle driving height difference is defined as H, the vehicle driving mileage is defined as S, the vehicle driving time is defined as T, the preset single-floor limit distance is defined as S, the preset limit parking time of the vehicle driving is defined as T, the floor limit height of the preset parking lot is defined as H, the initial parking space floor value of the parking lot where the vehicle is located is defined as L, and the parking space floor value of the parking lot where the vehicle is located is defined as N;
if S > S, and H =0, then N = 1;
if T < T, and | H | > H, and H > 0, N = L + | H |/H;
if T < T, and H > H, and H is less than 0, N = - (L- | H |/H).
In one embodiment, 500m < s < 1000m, 5min < t < 30min, 3m < h < 6 m.
The following specific examples are given in conjunction with the above functional relationships to further illustrate:
specifically, referring to fig. 4, a pressure sensor is used as a key device for estimating which floor the vehicle is located on, and the system can add parking position information using the pressure sensor to estimate the floor of the current position. The system will use the height and time data, and the system records the average height of the current; if the system detects an increase in altitude within a certain time and thereafter is a stable value along a certain altitude, the system increments the floor of the current estimated location by 1 increment level by 1. If the system detects that the altitude has dropped within a certain amount of time and the trailing edge is a stable value for a certain altitude, the system will subtract 1 from the floor for which level 1 is currently estimated.
Specifically, if the vehicle moves more than x kilometers and no y meter height difference is detected, the system will reset the floor level of the current estimated location to 1. The default value for x is 1 km. The default value of y is 3 meters. The values of x and y are configured by the user.
That is to say:
if (vehicle moving distance > x kilometer)
if (during this distance no y meters height difference detected)
Floor =1 of the current estimated position
Specifically, if the system detects an altitude increase too high (beyond a reasonable value of one floor level altitude) within a certain amount of time, it will estimate the current altitude by dividing the total altitude difference by y using the formula in the table below. This may occur in the following situations:
a. when the car uses the car elevator on the higher floor
b. When the automobile uses the spiral ramp to climb the higher floor
This may occur for some parking buildings that use spiral ramps or car lifts to bring the car directly to a particular level of the building.
L = floor of original estimated position
h = height gap detected by the system at a particular time
s = upper limit of a reasonable value of floor height
if(h>s)
Floor of current estimated position = L + h/y
Specifically, if the system detects that the altitude has dropped too much (beyond a reasonable value of one floor altitude) within a certain time, it will calculate using the formula in the table below. This may occur in the following situations:
a. when the automobile uses the lower floor of the automobile elevator
b. When the car uses the spiral ramp to go down to a lower floor
L = floor of original estimated position
h = height gap detected by the system at a particular time
s = upper limit of a reasonable value of floor height
if(h>s)
Floor of current estimated position = L-h/y
Specifically, the vehicle image comprises a vehicle reversing image, a vehicle driving record image and/or a vehicle panoramic image. And further, carrying out optical character recognition on the vehicle panoramic image to respectively obtain the parking space numbers of two adjacent parking spaces, and calculating to obtain the current parking space number of the parking space.
In one embodiment, the vehicle GPS position information is also sent, and the parking space number of the parking lot can be obtained by combining the parking space floor value of the parking lot where the vehicle is located, so that a specific parking space can be better found.
The parking position information management method can obtain the parking lot parking position number containing the parking position floor value of the parking lot where the vehicle is located through subsequent analysis and calculation by sending the parking position number of the parking lot and through more types of vehicle images and more ways or more data volumes, can know the parking position floor value of the parking lot where the vehicle is located, and can obtain more accurate parking position information through the rest parking position information contained in the parking position number of the parking lot.
As will be further described herein, the optical character recognition step and the step of transmitting the parking space number, the parking vehicle locator may be one of IVI functions that is automatically enabled when a vehicle enters a building identified by the GPS application as a multistorey parking lot. In this functional mode, the smart camera in the car can only capture 2-3 alphanumeric characters on the post that are large enough, as shown in the following figure. These characters represent the level of the parking lot. The smart camera will only keep one copy (one byte) of level information in the system/application database. Any camera with different levels of information will update/overwrite this byte of information. The last copy in the database is the location where the driver is parking. When the driver starts the reverse gear, the reverse camera is automatically triggered. The reverse phase camera has an Optical Character Recognition (OCR) function and can capture batch numbers, as with the bar number capture technique. The technology is well applied to automatic license plate recognition (ANPR) of an overspeed detector of a traffic police on a highway. Once a driver of the vehicle starts the parking device, the IVI system immediately records the down-level and section information, triggers the mobile phone of the driver through Bluetooth and sends the information to the mobile phone of the driver through short message service. Specifically, the short message may be sent in stages as "your vehicle is parked at parking lot # 127 of level B2". Thus, the main function of this additional function of the vehicle is to enable the driver to easily find the vehicle, and is a time-saving method of retrieving the vehicle without searching for the vehicle if the driver does not remember the position of the parked vehicle.
