Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0059] Example 1

[0060] See also Figure 1 , Figure 1 A flow chart of a vehicle traffic control method provided in this embodiment, which can reduce the time it takes for a vehicle to pass through a barrier, includes:

[0061] S101. When a vehicle enters a first lane area, first video data of the vehicle is obtained, and whether the vehicle triggers a pre-authentication event is determined according to the first video data.

[0062] See also Figure 2 , Figure 2 This is a schematic diagram of the vehicle traffic control principle provided for this embodiment.

[0063] Before entering the parking area, the vehicle needs to pass through the first lane area, the second lane area and the gate in sequence, and then the gate can be opened before the vehicle can enter the parking area. The traditional vehicle traffic control method is mostly to authenticate the vehicle through a camera or other device installed at the gate when the vehicle is about to reach the gate. If the authentication is passed, the gate will be opened to release the vehicle. Since the authentication takes a certain amount of time, the vehicle needs to slow down or stop when approaching the gate. After the gate is opened, it needs to accelerate again or restart the vehicle to pass through the gate, resulting in low efficiency and long time for vehicles to pass through the gate.

[0064] In order to improve the traffic efficiency of vehicles, the vehicle can be pre-authenticated when entering the first lane area.

[0065] For example, when a vehicle enters the first lane area, the first video data of the vehicle is first obtained through a camera or other equipment. Alternatively, when it is determined that the vehicle has entered the first lane area, a picture of the vehicle and the vehicle's surroundings is taken at a preset interval to determine whether the vehicle has triggered a pre-authentication event through the video or picture.

[0066] See also Figure 3 , Figure 3 A schematic diagram of the principle of the vehicle traffic control method provided in this embodiment.

[0067] The vehicle traffic control method can be executed by a vehicle traffic control device, namely a control machine. The control machine includes a control machine algorithm and a control machine application. The control machine algorithm is mainly used for vehicle identification and for determining whether the vehicle has triggered a corresponding event, while the control machine application determines the specific event.

[0068] See also Figure 4 , step S101 includes:

[0069] S1011. Determine whether there is license plate information in the first video data.

[0070] Since cameras and other devices are generally installed near the barrier, and the shooting distance and range of the camera are limited, when the vehicle is far away from the camera device, it may not be recognized in the first video data, or the vehicle's license plate information cannot be recognized, and the vehicle cannot be effectively identified or verified.

[0071] S1012: If so, obtain vehicle information and first lane information of the first lane area from the first video data.

[0072] When the license plate information can be normally recognized in the first video data, in addition to obtaining the license plate information, the required vehicle information and first lane information can also be obtained.

[0073] S1013. Determine whether the vehicle triggers a pre-authentication event based on the vehicle information and the first lane information.

[0074] Pre-authentication events require corresponding trigger conditions, and the trigger conditions are often related to the information of the vehicle itself. Therefore, only after the license plate information, vehicle information and first lane information can be normally identified can it be determined whether the vehicle has triggered a pre-authentication event.

[0075] See also Figure 5 , step S1013 includes:

[0076] S10131. Obtain the distance between the vehicle position and the authentication trigger mark, and determine whether the distance is less than or equal to a preset distance threshold.

[0077] like Figure 2 As shown, the vehicle information may include the vehicle position, and the first lane information may include an authentication trigger flag, which is Figure 2 The A mark in the figure can be a reference object such as a landmark or a trigger line.

[0078] When the license plate information of the vehicle can be recognized normally, the video data or image data of the vehicle can be obtained in real time. If the A mark appears in the video data or image data, the distance between the vehicle and the A mark can be obtained.

[0079] S10132: If the distance is less than or equal to the preset distance threshold, it is determined that the vehicle triggers a pre-authentication event.

[0080] If the distance between the vehicle and the A sign is less than or equal to the preset distance threshold, the preset distance threshold can be set as required. For example, if the preset distance threshold is set to 0, when the vehicle just touches the A sign, it is determined that the vehicle has triggered a pre-authentication event.

[0081] See also Figure 6 , step S1013 further includes:

[0082] S10133. Determine the vehicle angle and lane line inclination angle according to the vehicle posture and lane line position.

[0083] If the first lane area is not a straight area but a turning area, then after the license plate information can be recognized normally, the vehicle posture and the lane line position of the first lane area are continuously obtained. Since the vehicle body rotates when turning, forming a certain angle, the vehicle angle and lane line inclination angle can be determined based on the video information or picture information taken by the camera during the vehicle's driving process, and the video information or image information can be integrated.

[0084] Since the vehicle angle and lane line inclination angle are determined through video or image, a reference object or reference line can be determined when the camera shoots the video or image, and the vehicle angle and lane line inclination angle can be determined based on the reference object or reference line. For example, the angle is defined as positive when the front of the vehicle faces the camera, and negative when the rear of the vehicle faces the camera, and then the specific angle size is determined based on the reference line. In order to avoid errors, multiple shots can be used for calculation, and then the average angle can be taken.

[0085] S10134. Obtain the angle difference between the vehicle angle and the lane line inclination angle, and determine whether the angle difference is less than a preset angle value.

[0086] S10135. If it is less than the preset angle value, it is determined that the vehicle triggers a pre-authentication event.

[0087] Then, it is determined whether the angle difference between the vehicle angle and the lane line inclination angle is less than a preset angle value. If it is less than the preset angle value, it is determined that the vehicle triggers a pre-authentication event.

[0088] For example, the preset angle value is set to 45 degrees. If the angle difference is less than 45 degrees, it is determined that the vehicle is turning and heading towards the gate, and the vehicle can be pre-authenticated in advance.

[0089] This embodiment obtains the first video data of the vehicle and determines whether the vehicle has triggered a pre-authentication event based on the first video data, thereby facilitating subsequent authentication processing for vehicles that have triggered the pre-authentication time and excluding vehicles that have not triggered the pre-authentication event, thereby avoiding authenticating all vehicles and wasting time and resources.

[0090] S102: If the vehicle triggers a pre-authentication event, the vehicle is authenticated.

[0091] See also Figure 7 , step S102 includes:

[0092] S1021. Acquire characteristic information of the vehicle, where the characteristic information includes license plate information.

[0093] The license plate information is obtained synchronously when the first video information of the vehicle is obtained, and therefore, it can be used directly to authenticate the vehicle, or it can also be based on other information of the vehicle, such as the vehicle model, color and other characteristic information.

[0094] S1022. Query license plate information from a local license plate database.

[0095] like Figure 3 As shown, when authenticating a vehicle, since the local data and the platform data are not necessarily synchronized, or in order to save query time, you can first query whether there is a record of the license plate information from the local authentication database.

[0096] S1023. If the license plate information is not found, the license plate information is uploaded to the platform, and the license plate information is found through the platform.

[0097] S1024: If the license plate information is found, determine whether the vehicle corresponding to the license plate information has passed the authentication.

[0098] If the license plate information is not found locally, the license plate information is uploaded to the platform, which may be a cloud platform, and then queried through the platform. If the platform finds the license plate information, it can be determined that the vehicle corresponding to the license plate information has passed the authentication.

[0099] S103: If the authentication is successful, the vehicle is marked as a target vehicle.

[0100] If the authentication is successful, the vehicle can be marked to facilitate subsequent traffic control of the target vehicle.

[0101] S104, determining whether the target vehicle enters the second lane area; the distance between the first lane area and the barrier is greater than the distance between the second lane area and the barrier.

[0102] like Figure 2 As shown, in order to ensure that the vehicle has completed authentication when entering the second lane area, the first lane area can be divided into corresponding ranges according to the actual authentication time, the average speed of the vehicle and other data, to avoid the vehicle entering the second lane area before the authentication is completed, affecting the passage of subsequent vehicles.

[0103] When the target vehicle is determined to enter the second lane area, the barrier gate can be opened to release the target vehicle. Similarly, when the vehicle arrives at the barrier gate, it is also necessary to ensure that the target vehicle has been identified and the barrier gate has been opened. Figure 2 In the process, a reserved area C can be set between the second lane area and the gate. The second lane area can be divided according to the recognition time of the target vehicle entering the second area and the gate opening time, as well as the vehicle speed and other data, to ensure that the target vehicle has been identified and the gate has been opened when the vehicle exits the second recognition area and enters the reserved area C.

[0104] See also Figure 8 , step S104 includes:

[0105] S1041. Acquire second video data of a target vehicle, and acquire target vehicle information of the target vehicle and second lane information of a second lane area from the second video data.

[0106] S1042. Determine whether the target vehicle enters the second lane area based on the target vehicle information and the second lane information.

[0107] Before the target vehicle enters the second lane area, the target vehicle information and the second lane information of the target vehicle can be obtained through corresponding cameras and other equipment, and then it is determined whether the target vehicle has entered the second lane area based on the target vehicle information and the second lane information.

[0108] If the barrier is opened too early, it may cause other vehicles to cut in line or vehicles to evade fees, etc. Therefore, it is necessary to open it after confirming that the target vehicle has triggered the entry into the second lane area. Therefore, the position of the second lane area and the distance between it and the barrier need to be set according to the actual situation, which can ensure that vehicles can pass through the barrier without slowing down and prevent other vehicles from evading fees, etc.

[0109] See also Fig. 9, step S1042 includes:

[0110] S10421. Determine whether the chassis of the target vehicle has contacted the gate opening mark or gate opening area;

[0111] S10422: If the target vehicle has touched the gate opening sign or gate opening area, determine that the target vehicle has entered the second lane area.

[0112] The target vehicle information includes but is not limited to the target vehicle chassis, and the second lane information includes the gate opening sign. Figure 2 The B sign in the lane may be a landmark, a trigger line, or a trigger area. When the chassis of the target vehicle triggers the B sign, it is determined that the target vehicle enters the second lane area.

[0113] By setting a corresponding gate opening mark or gate opening area in the second lane area, and then obtaining target vehicle information of the target vehicle, such as the target vehicle chassis, etc., according to the relationship between the target vehicle chassis and the gate opening mark or gate opening area, the gate opening timing can be controlled more accurately.

[0114] S105: If the target vehicle enters the second lane area, the barrier gate is controlled to release the target vehicle.

[0115] Since the target vehicle has been pre-authenticated in the first lane area, when the target vehicle enters the second lane area, the barrier can be opened immediately to release the target vehicle.

[0116] In this embodiment, when a vehicle enters the first lane area, the vehicle is pre-authenticated. If the pre-authentication is passed, the vehicle is marked as a target vehicle. When the target vehicle enters the second lane area, the barrier gate is directly opened, so that when the vehicle enters the parking area from the second lane area, it does not need to stop in the process of passing through the barrier gate and can pass directly, thereby improving the vehicle's travel efficiency and reducing the vehicle's travel time.

[0120] An authentication module 112, used to authenticate the vehicle if the vehicle triggers a pre-authentication event;

[0121] A marking module 113 is used to mark the vehicle as a target vehicle if the authentication is passed;

[0122] The judging module 114 is used to judge whether the target vehicle enters the second lane area; the distance between the first lane area and the gate is greater than the distance between the second lane area and the gate;
