Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
According to the method for marking the parking space capable of parking, provided by the embodiment of the invention, the parking space is determined to have a vehicle for parking when the license plate is identified on the basis of judging whether the object exists on the parking space or not.
The first embodiment is as follows:
fig. 1 shows an implementation process of a method for marking a parking space according to an embodiment of the present invention, and for convenience of description, only the relevant parts of the present invention are shown.
In step S101, a parking space identifier and parking state information of a parking space corresponding to the parking space identifier are obtained, where the parking state information includes that a vehicle is parked and license plate information can be collected, no vehicle is parked, or a vehicle is parked but license plate information cannot be collected.
In the embodiment of the invention, the parking space identifier uniquely and definitely identifies the parking space of the parking lot, and plays a role in distinguishing and identifying, and can be a code identifier, an icon identifier or a symbol identifier, as long as the distinguishing and identifying functions can be achieved, and the specific method is not limited and can be selected according to specific conditions.
In the embodiment of the invention, the parking state information is used for representing the state of the parking space, and mainly comprises three conditions of parking with a vehicle and acquiring license plate information, no parking with a vehicle or parking with a vehicle but acquiring no license plate information. The specific step of parking a vehicle and acquiring license plate information is that the vehicle can be detected to exist on a parking space and the license plate information can be identified, so that the condition that the vehicle is parked on the parking space certainly can be determined; the parking without vehicles means that no vehicles are parked in the parking space under the condition that the existence of objects cannot be detected and the license plate information cannot be identified; in the embodiment of the invention, the situation that the parking of the vehicle in the parking space can be detected but the license plate information cannot be acquired exists, and the detection of the parking of the vehicle in the parking space means that only the existence of an object in the parking space is detected, which is primarily considered as the parking of the vehicle, but the license plate cannot be identified on the basis; therefore, in the case of the parking space, the vehicle can be parked under the actual condition, but the license plate number cannot be collected, or other sundries exist on the parking space, or the vehicle is not actually parked due to false recognition caused by paint spraying, water pits and the like.
In step S102, parking spaces where no vehicle is parked or where a vehicle is parked but license plate information is not collected are marked as parking spaces where vehicles can be parked. For example, 200 parking spaces are found in parking lot a, 150 parking spaces are determined as having vehicles to park, and the number of the license plate of the parked vehicle is not identified in the 150 parking spaces, so in the embodiment of the present invention, 50 parking spaces in which no vehicle is parked and 25 parking spaces in which no vehicle is parked but no license plate information is collected are marked as parkable parking spaces, that is, the marking result of the parkable parking spaces in parking lot a is 75.
The method for marking the parking space capable of parking, provided by the embodiment of the invention, simultaneously judges whether an object exists on the parking space and whether a license plate can be identified, if both the objects and the license plate are judged to be yes, the parking space is marked as the existing vehicle parking, and if the objects and the license plate are judged to be not simultaneously, the parking space is marked as the parking without the vehicle; if the vehicle license plate cannot be identified when the object exists in the parking space, the situation that no vehicle is parked in the parking space is judged, the detected object in the parking space is probably caused by the sundries, the paint spraying and the like, in order to avoid the situation, the original idle parking space cannot be effectively utilized, so that the parking space in the parking lot becomes tense, the parking space which can detect the object and cannot identify the vehicle license plate is marked as a parking space, the marking mode is more flexible, and the problem that the probability of error identification of a method for judging whether the vehicle is parked in the parking space in the prior art is too large, the time of a driver is wasted, great troubles are brought to the driver, and the problem that the mistakenly identified idle parking space cannot be utilized to the maximum in the parking lot is solved.
Example two:
fig. 2 shows a flowchart of another implementation of a method for marking a parking space according to an embodiment of the present invention, and for convenience of description, only the relevant portions of the method are shown. The difference from the first embodiment is that:
a method for marking parking spaces includes, before step S102:
step S201, determining whether the current time matches a preset parking peak time. If the determination result is yes, step S202 is executed, and if the determination result is no, step S203 is executed.
In the embodiment of the present invention, the manner of 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, determines that the current time is the parking peak time when the current time is within the set time, and determines that the current time is not the parking peak time when the current time is not within the set time. Alternatively, in another embodiment, the user may set that the parking peak period is considered when the occupancy ratio of the parking space in the parking lot is higher than a predetermined value, and the parking peak period is not considered when the occupancy ratio of the parking space in the parking lot is lower than the set value. It should be understood that the determination of the parking peak includes, but is not limited to, the above-described embodiments.
In step S202, a parking space in which the parking state information indicates that no vehicle is parked is marked as a parking available space.
For example, there are 200 parking spaces in parking lot a, and there are 150 parking spaces in which a vehicle is parked according to the identification, and there are 25 parking spaces in which no license plate number of the parked vehicle is identified, then in the embodiment of the present invention, the 50 parking spaces in which the parking status information is "no vehicle is parked" are marked as parkable parking spaces, that is, the marking result of the parkable parking spaces in parking lot a is 50.
In the embodiment of the invention, because the traffic flow is large in the parking peak period, especially in places with narrow spaces such as parking lots, the traffic jam is very easy to cause, and the planning management of the parking lots is further influenced, only the parking position where the parking state information is determined as no vehicle is parked is marked as a parking space in the parking peak period, and the condition that the vehicle is detected to enter but the license plate is not recognized is all regarded as the state where the vehicle is parked, so that the parking space where the driver is guided to arrive by the information of the parking lot is determined as the state where no vehicle is parked. The parking lot has the advantages that the situation that due to the fact that unlicensed vehicles and temporary vehicles are parked, the parking places which cannot be parked originally are marked as parking places is avoided, parking users can mistakenly think that the parking lot still has the position to park, vehicles are prone to being blocked, and user experience is greatly reduced is avoided.
In step S203, the parking spaces where no vehicle is parked or where there is a vehicle parked but no license plate information is collected are marked as parking spaces where the vehicle can be parked.
In the embodiment of the invention, when the current time is judged not to be in the parking peak period, the positions where the vehicles can move in the parking lot are relatively more than those in the parking peak period, and a certain degree of misjudgment rate can be accepted, so that in order to maximize the utilization of the parking places in the parking lot, the parking places where no vehicle is parked and where the vehicle is parked but no license plate information is collected are marked as the parking places where the vehicles can be parked.
In another embodiment of the present invention, the parking status information further includes a pause, and step S102 specifically includes: and marking the parking spaces with the parking state information of no vehicle parking and suspended use as parking spaces.
In the embodiment of the invention, a certain parking space is arranged for internal staff in the parking lot, or certain parking spaces are reserved for specific users, and the parking lot is not opened to the outside and is temporarily stopped for use; in special cases, such as a parking peak, when the demand for parking spaces is large, if the parking spaces are not parked, the parking spaces are not opened to the outside, which will cause waste of resources in the parking lot.
In an embodiment of the present invention, the parking space identifier includes an area identifier, and the method for marking a parking space further includes:
and acquiring the parking space identification of the parking space, and carrying out classification marking on the parking space according to the area identification of the parking space.
In the embodiment of the invention, the parkable parking spaces are classified and marked according to the area identification, so that a parking lot management worker or a parking user can intuitively know the conditions of the parkable parking spaces in each area of the parking lot, the parkable parking spaces are conveniently managed by the parking lot management worker, the parkable parking spaces are conveniently searched by the parking user, the general conditions and positions of the parkable parking spaces are conveniently searched, the parkable parking spaces are favorably guided to be searched by the parking user, and the use experience of the user is improved.
Or in another embodiment of the present invention, the parking space identifier includes a direction identifier, and the method for marking a parking space includes:
and acquiring a parking space identifier of the parking space, and carrying out classification marking on the parking space according to the azimuth identifier of the parking space.
In the embodiment of the present invention, the direction identifier may be an arrow identifier, a code identifier, or a coordinate identifier, so as to divide the direction of the parking space, and the direction identifier is not limited specifically, and may be selected according to specific situations.
In the embodiment of the invention, the azimuth mark is correspondingly changed relative to the real-time position of the parking user, the position information of the parking user and the position information of the parking space are imported into the two-dimensional map of the parking lot and are expressed by coordinates, and the specific azimuth of the parking space relative to the parking user is determined according to the two-dimensional map so as to determine the azimuth mark of the parking space. For example, if the current position of the user is at the coordinate position of (2, 2) of the a-car parking lot two-dimensional map and the parking space is at the coordinate position of (2,8), then the orientation of the parking space is identified as the east-right orientation.
In the embodiment of the invention, the parkable parking spaces are classified and marked according to the orientation marks, so that a parking lot management worker or a parking user can intuitively know the conditions of the parkable parking spaces in all directions of the parking lot, the parkable parking spaces can be conveniently managed by the parking lot management worker, the parkable parking spaces can be conveniently searched by the parking user, the general conditions and the orientation of the parkable parking spaces can be conveniently searched, the parkable parking space can be conveniently guided to be searched by the parking user, and the use experience of the user is improved.
In an optimized embodiment of the present invention, the parking space identifier may also include an area identifier and a direction identifier at the same time, and in particular, the implementation manner is as in the above-mentioned embodiment, which is not described herein again.
The method for marking the parking space capable of parking, provided by the embodiment of the invention, simultaneously judges whether an object exists on the parking space and whether a license plate can be identified, if both the objects and the license plate are judged to be yes, the parking space is marked as the existing vehicle parking, and if the objects and the license plate are judged to be not simultaneously, the parking space is marked as the parking without the vehicle; if the vehicle license plate cannot be identified when the object exists in the parking space, the situation that no vehicle is parked in the parking space is judged, the detected object in the parking space is probably caused by the sundries, the paint spraying and the like, in order to avoid the situation, the original idle parking space cannot be effectively utilized, so that the parking space in the parking lot becomes tense, the parking space which can detect the object and cannot identify the vehicle license plate is marked as a parking space, the marking mode is more flexible, and the problem that the probability of error identification of a method for judging whether the vehicle is parked in the parking space in the prior art is too large, the time of a driver is wasted, great troubles are brought to the driver, and the problem that the mistakenly identified idle parking space cannot be utilized to the maximum in the parking lot is solved.
