Detailed ways

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The parking space marking method provided by the embodiment of the invention determines whether there is an object on the parking space, and on the basis of determining that there is an object on the parking space, when the license plate is recognized, it is determined that the parking space has the vehicle parked.

Embodiment 1:

FIG. 1 shows an implementation flow of a parking space marking method provided by an embodiment of the present invention. For convenience of description, only parts related to the present invention are shown.

In step S101, the parking space identifier and the parking state information of the parking space corresponding to the parking space identifier are obtained, and the parking state information includes that the vehicle is parked and the license plate information can be collected, no vehicle is parked, or the vehicle is parked but collected. No license plate information.

In the embodiment of the present invention, the parking space identifier uniquely identifies the parking space of the parking lot, and functions as a distinguishing and identifying function, which may be a code identification, an icon identification, or a symbol identification, as long as the distinction and the identification function can be achieved. The specifics are not limited and can be selected according to the specific circumstances.

In the embodiment of the present invention, the parking state information is used to represent the state of the parking space, and may mainly include three situations in which the vehicle is parked and the license plate information can be collected, no vehicle is parked, or the vehicle is parked but the license plate information is not collected. Wherein, the vehicle parking and collecting the license plate information specifically means that an object exists on the parking space can be detected, and the license plate information can be recognized, then the situation can be determined that the vehicle must be parked on the parking space; When it is detected that no object exists and the license plate information is not recognized, it is considered that the parking space must be parked without a vehicle; and in the embodiment of the present invention, there is a case where it is detected that the vehicle is parked on the parking space but The license plate information cannot be collected. In this case, the detection of the parking space with the vehicle parking means that only the presence of an object on the parking space is detected. It is initially considered that there is a vehicle parked, but on this basis, the license plate is not recognized; In the case, the actual situation of the parking space may be that the vehicle is parked, but the license plate number cannot be collected. It may also be that there are other sundries on the parking space, or that the vehicle is misidentified due to painting, puddles, etc., and there is no actual parking on the parking space.

In step S102, the parking space where no vehicle is parked and where the vehicle is parked but the license plate information is not collected is marked as a parking space. For example, in the parking lot of A, there are 200 parking spaces, and 150 parking spaces are judged to be parked. If 25 of the 150 parking spaces do not recognize the license plate number of the parking vehicle, then in the embodiment of the present invention, The 50 parking spaces with “no vehicle parking” and the 25 parking spaces with “vehicle parking but no license plate information” are marked as parking spaces, ie the number of parking spaces in parking lot A is 75.

Embodiment 2:

FIG. 2 shows an implementation flow of another parking space marking method provided by an embodiment of the present invention.

For the sake of convenience of explanation, only parts related to the present invention are shown. The difference from the first embodiment is:

A parking space marking method, before step S102, further comprising: step S201, determining whether the current time meets a preset parking peak time. If the determination structure is YES, step S202 is performed, and if the determination result is no, step S203 is performed.

In the embodiment of the present invention, the method for determining whether the current time is the parking peak time may be that the user sets the parking peak time according to the previous parking data, and when the current time is within the set time, the current time is determined to be the parking time. Peak hours, if not in the above time, are not peak hours. Alternatively, in another embodiment, the user may set that when the parking space occupancy ratio of the parking lot is higher than a certain preset value, it is considered to be a parking peak period, and is lower than the above-mentioned set value, not a parking peak period. It should be understood that the manner in which the peak parking period is judged includes, but is not limited to, the embodiments described above.

In step S202, the parking space information is marked as a parking space for a parking space where no vehicle is parked.

For example, in the parking lot of A, there are 200 parking spaces, and among the 150 parking spaces, according to the identification, it is known that there is a vehicle parking, and 25 of the parking spaces do not recognize the license plate number of the parking vehicle, then in the embodiment of the present invention, The 50 parking spaces whose parking state information is "no vehicle parking" are marked as parking spaces, that is, the number of marked parking spaces in the parking lot A is 50.

In the embodiment of the present invention, due to the large traffic volume during the peak parking period, especially in a place with a small space such as a parking lot, it is extremely easy to cause vehicle blockage, thereby affecting the planning management of the parking lot, so only the parking state information is determined during the peak parking time. The parking space for parking without a vehicle is marked as a parking space, and the case where the vehicle is detected but the vehicle license is not recognized is regarded as a state in which the vehicle has been parked, and the parking space that ensures that the driver passes the information of the parking lot must be No vehicle parking status. Avoiding the reason that there is an unlicensed car and a temporary car parking, the parking space that was originally unparkable is marked as a parking space, so that the parking user mistakenly thinks that the parking lot still has a parking position, which is likely to cause vehicle clogging, greatly reducing the user experience. The situation happened.

In step S203, the parking space where no vehicle is parked and where the vehicle is parked but the license plate information is not collected is marked as a parking space.

In the embodiment of the present invention, when it is judged that the current time is not the peak period of parking, the position of the vehicle in the parking lot is relatively more than the peak period of the parking, and a certain degree of false positive rate can be accepted, so in order to lift the parking The parking spaces in the venue are maximized, and parking spaces with no vehicles parked and vehicles parked but no license plate information are collected are marked as parking spaces.

In another embodiment of the present invention, the parking status information further includes suspended use, and step S102 is specifically: marking the parking status information as a parking space without parking and parking.

In the embodiment of the present invention, the parking lot will arrange a certain parking space for the internal staff, or reserve some parking spaces for a specific user, and will not open to the outside world, and the external performance is suspended; at special times, such as the peak parking period, the parking space In the case of relatively large demand, if these parking spaces are not parked and are not open to the public, it will inevitably result in waste of parking lot resources. Therefore, in these cases, these parking spaces will be opened to other users for use, and parking will be increased. The efficiency of the field will also bring additional benefits to the parking lot.

In the embodiment of the present invention, the parking space identifier includes an area identifier, and the parking space marking method further includes:

Obtaining a parking space identifier of the parking space, and classifying the parking space according to the area identifier of the parking space.

In the embodiment of the present invention, by classifying and marking the parking spaces according to the area identifiers, the parking lot management staff or the parking users can intuitively understand the parking spaces of the parking lots in various areas, which is convenient for the parking lot management staff. The management of parking spaces can also help parking users to find the approximate situation and location of parking spaces, which is helpful for guiding parking users to find parking spaces and improve the user experience.

Or in another embodiment of the present invention, the parking space identifier includes an orientation identifier, and the parking space marking method further includes:

Obtaining a parking space identifier of the parking space, and classifying the parking space according to the orientation identifier of the parking space.

In the embodiment of the present invention, the orientation identifier may be an arrow identifier, a code identifier, or a coordinate identifier, etc., so as to achieve the division of the direction of the parking space, which is not limited, and may be selected according to specific conditions.

In the embodiment of the present invention, the orientation identifier is correspondingly changed with respect to the real-time location of the parking user, and the location information of the parking user and the location information of the parking space are introduced into the two-dimensional map of the parking lot by coordinates, according to the The two-dimensional map determines the orientation of the parking space relative to the specific location of the parking user. For example, if the current location of the user is in the coordinate position of (2, 2) of the two-dimensional map of the parking lot of A, and the parking space is at the coordinate position of (2, 8), then the orientation of the parking space is marked as the positive east position.

In the embodiment of the present invention, by classifying and marking the parking spaces according to the orientation identifiers, the parking lot management staff or the parking users can intuitively understand the situation that the parking spaces can be parked in all directions of the parking lot, and the parking garage management staff is convenient. The management of parking spaces can also help parking users to find the approximate situation and orientation of parking spaces, which is helpful for guiding parking users to find parking spaces and improve the user experience.

In an optimized embodiment of the present invention, the parking space identifier may also include an area identifier and an azimuth identifier. Specifically, the implementation manner is the same as the foregoing embodiment, and details are not described herein again.
