Description

Technical Field

[0001] The present invention relates to the technical field of parking safety, and in particular to an intelligent prompting method and system for a vehicle turning point. Background Art

[0002] Whether it is a ground parking lot or an underground parking lot, it is easy to be unable to see the situation at the turn due to obstruction, light and other issues. Especially in underground parking lots, not only is the light dim, but there are also many blind spots in the field of vision.

[0003] The prior art usually sets a convex mirror at the turning point, which can expand the driver's field of vision and help the driver to find vehicles or pedestrians on the other side of the curve in advance, so as to take timely measures to avoid collision. However, the assistance effect of the convex mirror itself is affected by the installation position and the field of vision obstruction, and it is easy to cause blurred display due to the dirt on the mirror surface, thus failing to effectively reduce the risk of traffic accidents. Therefore, there is an urgent need for a method that can effectively prompt users at the turning point of the vehicle. Summary of the invention

[0004] In order to solve the above problems in the prior art, the present invention provides an intelligent prompt method and system for vehicle turning, which can improve the driving safety of the vehicle when turning.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, the present invention provides an intelligent prompting method for a vehicle turning, comprising the steps of:

[0007] A real-time lane image on each lane is obtained by a camera arranged at a turning point, and a real-time number of active animals on each lane is obtained according to the real-time lane image, wherein the active animals in the real-time number of active animals are vehicles and pedestrians;

[0008] It is determined whether the number of real-time active animals on at least one lane at the current turn is greater than 0. If so, a prompt device at the current turn is controlled to give a prompt according to the number of real-time active animals on each lane.

[0009] The beneficial effect of the present invention is that when there are moving animals in the lane at a turn, a reminder is given through the prompt device at the turn, so that the vehicle can slow down and observe in advance according to the prompt device, effectively reducing the risk of traffic accidents at the turn.

[0010] Optionally, the method further comprises the steps of:

[0011] Display the real-time number of active animals in each lane of the parking lot on the vehicle terminal;

[0012] When a first vehicle is located in a first lane of a first curve and the first vehicle moves toward the first curve, it is determined whether the number of real-time active animals in other lanes of the first curve is greater than 0. If so, a vehicle closest to the first curve among the real-time active animals in other lanes whose number of real-time active animals is greater than 0 is highlighted on the vehicle-mounted terminal of the first vehicle.

[0013] According to the above description, when a vehicle is connected to the parking lot system, the real-time number of active animals in each lane will be displayed on the vehicle terminal, so that the owner can know the traffic conditions in the parking lot through the vehicle terminal, including the traffic conditions in different lanes at the turning point, thereby further reducing the risk of traffic accidents at the turning point.

[0014] Optionally, the method further comprises the steps of:

[0015] Calculate the predicted number of active animals at the next time node based on the real-time number of active animals on each lane in the parking lot, and determine whether each curve is congested based on the predicted number of active animals in each lane. If so, mark it as a congested curve;

[0016] When planning a route for vehicles in a parking lot, the weight of the congested curve in the route planning is reduced.

[0017] According to the above description, by predicting the congestion situation of the curve and reducing the weight value of the congested curve in route planning, the risk of traffic accidents at the curve can be further reduced.

[0018] Optionally, the method further comprises the steps of:

[0019] The real-time lane images on each lane are displayed on the monitoring interface of the parking lot.

[0020] Optionally, the prompting device includes a signaling device, a sound device and a display device.

[0021] In a second aspect, the present invention provides an intelligent prompt device for a vehicle turning point, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the following steps when executing the computer program:

[0022] Acquire real-time lane images on each lane through a camera arranged at a turning point, and obtain the real-time number of active animals on each lane according to the real-time lane images;

[0023] It is determined whether the number of real-time active animals on at least one lane at the current turn is greater than 0. If so, a prompt device at the current turn is controlled to give a prompt according to the number of real-time active animals on each lane.

[0024] Optionally, when the processor executes the computer program, the processor further comprises the steps of:

[0025] Display the real-time number of active animals in each lane of the parking lot on the vehicle terminal;

[0040] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] Embodiment 1

[0042] This embodiment is suitable for parking lot application scenarios, especially underground parking lots with obstructed vision and dim light. The existing technology uses convex mirrors to provide vision, and the risk of traffic accidents is still relatively high. This embodiment uses a camera to obtain the real-time number of active animals in the lane, and then reminds according to the real-time number of active animals to reduce the risk of traffic accidents at turns. See the following discussion for details.

[0043] Please refer to Figure 1 , an intelligent prompting method for a vehicle turning, comprising the steps of:

[0044] S1. Obtain real-time lane images on each lane through a camera set at a turning point, and obtain the real-time number of active animals on each lane based on the real-time lane images;

[0045] Among them, the active animals in the real-time active animal count are vehicles and pedestrians, that is, a camera is set at the turning point, and the vehicle and pedestrian conditions on the lane are obtained through the camera, that is, the real-time lane image. By analyzing the real-time lane image, the real-time active animal number on each lane, that is, the number of vehicles and pedestrians, is obtained.

[0046] Among them, the lanes in this embodiment refer to roads for vehicles to pass in different directions. For example, entering a curve is one lane. When passing the curve, the direction of the vehicle traffic road changes, which is another lane. If there are two forks after passing the curve, there are two corresponding lanes.

[0047] In this embodiment, the following steps are also included:

[0048] The real-time lane images on each lane are displayed on the monitoring interface of the parking lot.

[0049] Among them, if the parking lot is an underground parking lot in a certain community, it will be displayed on the property monitoring interface of the community to facilitate property management.

[0050] S2. Determine whether the number of real-time moving animals on at least one lane at the current turn is greater than 0. If so, control the prompt device at the current turn to give a prompt according to the number of real-time moving animals on each lane.

[0051] In this embodiment, the prompt device includes a signal device, a sound device and a display device. The signal device is such as a signal light; the sound device is such as a buzzer, a horn; the display device is such as a display screen and the like. This type of prompt device is set at the turning point and can be coordinated with a convex mirror.

[0052] Among them, as long as the number of real-time active animals on one lane is greater than 0, for example, there is a pedestrian on the lane at the current turn, a reminder will be given through the prompt device at the current turn to reduce the risk of traffic accidents at the turn. If there are vehicles or pedestrians in lanes in multiple directions at the same time, the corresponding prompt devices in multiple directions can provide sound and light prompts. In this way, motor vehicle drivers, non-motor vehicle drivers and pedestrians can adjust the speed and direction of driving or walking according to the prompt device.

[0053] S3, displaying the real-time number of active animals on each lane in the parking lot on the vehicle terminal;

[0054] At present, some parking lot systems are equipped with navigation functions, car search functions, etc., which can be connected to the vehicle terminal. At this time, the real-time number of active animals in each lane in the parking lot can be displayed on the vehicle terminal, so that the owner can drive according to the displayed information.

[0055] S4. When the first vehicle is located in the first lane of the first curve and the first vehicle is moving toward the first curve, determine whether the number of real-time active animals in other lanes of the first curve is greater than 0. If so, highlight the vehicle closest to the first curve among the vehicles in the other lanes whose number of real-time active animals is greater than 0 on the vehicle-mounted terminal of the first vehicle.

[0056] Among them, not only are there reminder devices at the turns, but there are also emphasis reminders on the on-board terminals, such as red signs, bold and enlarged signs, flashing signs, etc.

[0057] Combining steps S3 and S4, it can be seen that when the system of some parking lots is available for users to log in, such as owners of residential areas, consumers in shopping malls, or tourists in scenic spots, etc., when users log in to the parking lot system and navigate, the real-time number of active animals on each lane in the parking lot will also be displayed on the navigation interface, so that pedestrians can also adjust themselves according to the situation.

[0058] Among them, step S2 and step S3 are not executed sequentially, but are performed simultaneously. Step S2 is used to control the prompt device at the turning point, and steps S3 and S4 are used to control the display of the vehicle terminal. There is no necessary order between the two, and they can be processed and implemented separately.

[0059] S5. Calculate the predicted number of active animals at the next time node according to the real-time number of active animals on each lane in the parking lot, and determine whether each curve is congested according to the predicted number of active animals in each lane. If so, mark it as a congested curve.

[0060] Among them, step S5 is not executed in sequence with step S2, step S3, and step S4. Step S5 and step S6 are processes for other vehicle route planning in the process of obtaining the real-time number of active animals in step S1.

[0061] Specifically, the vehicles and pedestrians in the predicted number of active animals need to be converted into a congestion coefficient through weight coefficients to determine whether the lane is congested, where the weight coefficient of vehicles is greater than the weight coefficient of pedestrians.

[0062] The speed and direction of vehicles and pedestrians in the lanes can be obtained through the position changes of active objects in multiple image frames, so that the moving positions of vehicles and pedestrians can be predicted. For example, if the time node is 3 seconds, the position of the vehicle in 3 seconds can be predicted, and the driving conditions of these vehicles in all lanes can be known. The same is true for pedestrians, so as to determine whether there is congestion in each curve. If so, it will be marked as a congested curve.

[0063] S6. When planning routes for vehicles in the parking lot, reduce the weight of congested curves in route planning.

[0064] Among them, route planning is usually carried out based on the shortest distance or shortest time. This embodiment reduces the weight value of congested curves in route planning, taking the safety factor of the curve into consideration, thereby further reducing the risk of traffic accidents at the curves.

[0065] In summary, this embodiment effectively reduces the risk of traffic accidents at turns through the prompt device at the turns, the display control of the vehicle terminal, and the design during route planning.
