Detailed Description
The large-sized target vehicle in the application can specifically refer to large-sized vehicles such as trucks or buses, and the small-sized target vehicle can specifically refer to common vehicles such as private cars, and in the specific embodiment, the truck is mainly taken as an example for illustration; in practical application, supervisory equipment (for example camera) on the high-order video stake can monitor 4 parking stalls, if No. 2 parking stalls have stopped the freight train, just see preceding parking stall or not, no. 3 and No. 4 parking stalls in front.
Referring to fig. 1, the present application provides an embodiment of a parking charging timing method, which includes steps 101 to 105.
101. And acquiring the information of the trolley detection frame.
The method comprises the steps of acquiring the information of a trolley detection frame of a small target vehicle parked in a parking space in a monitoring picture, wherein the information of the trolley detection frame specifically comprises the information of a vehicle size frame formed according to the appearance of the small target vehicle in the monitoring picture, and the information can be used for detecting the size of the small target vehicle so as to judge whether a follow-up large target vehicle shields the small target vehicle.
102. And acquiring information of a detection frame of the cart.
The method comprises the steps of acquiring the information of a large-size target vehicle detection frame in a parking space in a monitoring picture, wherein the information of the small-size target vehicle detection frame specifically comprises the information of a vehicle size frame formed according to the appearance of the large-size target vehicle in the monitoring picture, and the information can be used for detecting the size of the large-size target vehicle so as to judge whether the subsequent large-size target vehicle shields the small-size target vehicle.
103. And tracking and recording the time of entering the parking space and the time of exiting the parking space of the large-scale target vehicle.
Tracking and recording the time of entering a parking space and the time of exiting the parking space of the large-scale target vehicle through the content of the monitoring picture; for example, a tracking record of a large-scale target vehicle or a small-scale target vehicle can be realized by extracting and storing a vehicle feature point set (such as a license plate number) in a monitoring picture, and the step mainly refers to tracking record of the time of entering a parking space and the time of exiting the parking space of the large-scale target vehicle.
104. Whether the large-sized target vehicle shields the small-sized target vehicle is judged.
And judging whether the large-sized target vehicle shields the small-sized target vehicle or not according to the trolley detection frame information and the cart detection frame information. In a specific implementation manner, the overlapping area between the vehicle frames of the two vehicles can be calculated according to the trolley detection frame information and the cart detection frame information, and whether the large-sized target vehicle shields the small-sized target vehicle can be judged by comparing whether the overlapping area exceeds a preset value.
105. A billing period for the small target vehicle is determined.
Because the time for the large-sized target vehicle and the small-sized target vehicle to enter and exit the vehicle is divided into the morning and evening, the charging period of the small-sized target vehicle needs to be determined according to the conditions when the shielding occurs, and the method specifically comprises the following steps:
(1) If shielding occurs, and the large-sized target vehicle enters the parking space later than the small-sized target vehicle and exits the parking space later, the time of entering the small-sized target vehicle is obtained, and the charging period of the small-sized target vehicle is determined to be the time from the time of entering the parking space of the small-sized target vehicle to the time of entering the parking space of the large-sized target vehicle.
(2) If shielding occurs, and the large-sized target vehicle enters the parking space earlier than the small-sized target vehicle and exits the parking space earlier, the time of exiting the small-sized target vehicle is obtained, and the charging period of the small-sized target vehicle is determined to be the time of exiting the large-sized target vehicle to the time of exiting the small-sized target vehicle.
The sequence of steps 101 to 103 is not limited, and may be performed simultaneously in practical applications.
The traditional method judges whether the vehicle enters and exits the vehicle position through geomagnetism installed in each road parking space, and determines whether the vehicle is in a parking or driving-away state, so that the charging management of the vehicle parked in the road parking space is realized, and the method has the problems of complex installation, high cost, difficult maintenance and the like although the judgment result is more accurate; meanwhile, the method cannot identify license plate numbers and parking space entering and exiting time of blocked vehicles, so that a patrol inspector can be informed of unpaid vehicles to conduct manual processing, and malicious vehicles escaping from fees cannot reserve evidence such as license plate information, and the cost of in-road parking charging management work cannot be increased. The parking charging timing method of the embodiment of the application can effectively improve the condition of inaccurate timing charging of the small-sized target vehicle caused by the shielding of the large-sized vehicle on the front parking space by the monitoring picture, and reduce the labor cost of in-road parking charging management.
Referring to fig. 2, another embodiment of the present application provides a parking charging timing method, including:
201. License plate information of the small-sized target vehicle and the large-sized target vehicle is obtained.
License plate information of the small-sized target vehicle and the large-sized target vehicle in the monitoring picture is acquired so as to carry out charge management after the license is stored.
202. The locations and numbers of the large target vehicles and the small target vehicles are determined.
And respectively determining the positions and the number of the large target vehicles and the small target vehicles in the monitoring picture through the vehicle detection model.
In one embodiment, when it is desired to detect the position and number of small target vehicles in the monitoring screen, a small target vehicle detection algorithm based on deep learning, such as YOLO (YOLO, you only look once) or SSD (SSD, single shot multibox detector) target detection algorithm, may be used. The monitoring equipment on the high-level video pile can be arranged at a place with a height of six meters to collect video and picture information of the vehicle, wherein the vehicle refers to the whole vehicle seen on a monitoring picture, for example, when the vehicle runs away from a camera, the whole vehicle is a vehicle tail and a vehicle roof and even comprises part of a vehicle body; the vehicle runs close to the camera direction, and then the whole vehicle is a head and a roof, and even comprises part of a vehicle body.
In one embodiment, when the positions and the number of the large target vehicles in the monitoring screen need to be detected, an algorithm consistent with a small target vehicle detection algorithm may be used, or an algorithm inconsistent with the small target vehicle detection algorithm may be used, for example, a dedicated large target vehicle detection model. When the consistent detection algorithm is selected to detect two kinds of target vehicles, parameter settings suitable for large-scale target vehicles or small-scale target vehicles are needed to be made respectively, namely after the small-scale target vehicles are detected, the relevant parameter settings in the detection algorithm are adjusted to enable the corresponding large-scale target vehicle detection models so as to detect the positions and the quantity of the large-scale target vehicles, and the detection rate of the large-scale target vehicles is improved.
If the large target vehicle is at a remote location and the vehicle volume is not large, the large target vehicle can be detected by using the small target vehicle detection model, but detection is difficult when the small target vehicle detection model is close to the camera or the volume is large, and part of the large target vehicle may not be detected by using the small target vehicle detection model, and more large target vehicles can be detected by using the special large target vehicle detection model. Therefore, preferably, the embodiment of the application detects the corresponding target vehicle information by using the special small target vehicle detection model and the large target vehicle detection model respectively, then, the overlapping result of the target vehicles detected by the two models needs to be calculated, and the positions and the number of the repeatedly detected small target vehicles and large target vehicles are determined by combining the license plate recognition result; the detection results of the large-scale target vehicles detected by the two models are required to be combined, only 1 result is reserved, specifically, when the overlapping result appears, the detection results of the large-scale target vehicle detection models are used as the reference, so that the positions and the number of the large-scale target vehicles existing in the current monitoring picture are finally determined, the detection rate of the large-scale target vehicles is improved, meanwhile, the parking condition of parking spaces in a patrol road is facilitated, or whether the vehicles pre-parked in the parking spaces are released or not is determined so that the vehicles pre-parked in the parking spaces can be parked.
203. And acquiring the information of the trolley detection frame.
204. And acquiring information of a detection frame of the cart.
205. And tracking and recording the time of entering the parking space and the time of exiting the parking space of the large-scale target vehicle.
206. Whether the large-sized target vehicle shields the small-sized target vehicle is judged.
Calculating a first overlapping area of a vehicle frame of the large-sized target vehicle and a vehicle frame of the small-sized target vehicle according to the trolley detection frame information and the cart detection frame information, and determining that the large-sized target vehicle shields the small-sized target vehicle if the first overlapping area is larger than or equal to a first preset value; and if the first overlapping area is smaller than a first preset value, determining that the large-sized target vehicle does not shade the small-sized target vehicle.
207. A billing period for the small target vehicle is determined.
When the large target vehicle shields the small target vehicle, the operation of determining the charging period of the small target vehicle is similar to the contents described in the foregoing steps (1) to (2), and detailed description thereof will not be repeated here;
When the large-sized target vehicle does not shade the small-sized target vehicle (it is understood that a general car can be automatically recognized), the operation of determining the charging period of the small-sized target vehicle may be to determine the charging period of the small-sized target vehicle according to the obtained driving-in parking space time and driving-out parking space time of the small-sized target vehicle, which illustratively includes, but is not limited to:
1. when the truck is completely stopped in the parking space (recorded as time B), if the ordinary trolley is already parked in the front parking space, the state of the ordinary trolley is changed into a suspected departure state, and the time for entering the ordinary trolley into the parking space is recorded (recorded as time A):
And (1), if the common trolley on the front parking space exits the parking space at the time C and is identified before the truck exits the parking space, recording the exiting time of the common trolley as the time C, and taking the charging period as the time A to the time C.
And (2) when the truck is driven out (recorded as time D), the parking condition of the common trolley on the front parking space is re-identified, if the common trolley is still on the parking space, tracking and timing are continued, and if the time of the common trolley leaving is time E, the charging period is from time A to time E.
2. When the truck is completely stopped in the parking space (recorded as time B), if the ordinary trolley is not parked in the front parking space, and the ordinary trolley is driven into the front parking space and is identified (time F) in the parking time of the truck, the driving-in time of the ordinary trolley is recorded as time F:
<1>, the ordinary trolley is driven out and recognized (time G) in the parking time of the truck, and the charging period of the ordinary trolley is time F to time G.
And (2) if the truck is out, re-identifying the parking condition of the common trolley on the front parking space, and if the front trolley is found to be out but lacks the out-of-car-space record due to special conditions, deleting the in-car-record of the trolley to avoid charge disputes such as multi-charge and the like, and directly releasing the vehicle.
208. And acquiring the parking space frame information of each parking space and judging whether the large-scale target vehicle is blocked in the front parking space.
After the parking space frame information of each parking space is acquired through the parking space information table, according to the parking space frame information and the large vehicle detection frame information, a second overlapping area of a vehicle frame of the large target vehicle and a parking space frame of a previous parking space can be calculated, and if the second overlapping area is larger than or equal to a second preset value, the large target vehicle is determined to be blocked in the previous parking space; and if the second overlapping area is smaller than a second preset value, determining that the large-scale target vehicle does not block the front parking space. The front parking space refers to one or more parking spaces in front of the parking space where the large target vehicle is located, and the front parking space can be used for parking the small target vehicle. Here, whether the large target vehicle is blocked in the front parking space is determined, which is beneficial to the in-road parking management system or personnel to perform operations such as inspection on the parking condition (for example, whether the vehicle is parked beyond the parking space line). It should be noted that, in the step 208, the step of acquiring the parking space frame information of each parking space and the step of determining whether the large-scale target vehicle blocks the preceding parking space may be performed separately, for example, the step of acquiring the parking space frame information of each parking space may be performed before the step 204, that is, the sequence of performing any of the steps 201 to 203 is not limited, and similarly, the step of determining whether the large-scale target vehicle blocks the preceding parking space may be performed after the step 204.
Steps 203 to 207 are similar to steps 101 to 105, respectively, and are not described here again; the order of execution of any of steps 208 and 204 is not limited.
The method of the embodiment of the application can improve the detection rate of the truck, and meanwhile, the toll collection can be realized as accurately as possible when the truck shields the front parking space or the vehicle parked in the front parking space; if the condition that the record of the small target vehicle is lost when the truck stops is found, the condition that the small target vehicle enters the parking space or exits the parking space can be effectively avoided by adjusting the charging time period.
