Description

Technical Field

[0001] The present invention belongs to the technical field of parking fee collection, and in particular relates to an unmanned aerial vehicle on-street parking space evidence collection system and method. Background Art

[0002] With the rapid advancement of urbanization, the number of private cars in cities has increased dramatically, and on-street parking resources have become increasingly tight, becoming a key factor restricting the smooth flow of urban traffic and the quality of life of residents. Reasonable planning of on-street parking spaces and improving the efficiency of parking space use are of great significance to alleviating the problem of parking difficulties and optimizing the urban traffic environment. However, the current management of on-street parking spaces mainly relies on manual inspections, video evidence collection, and patrol car evidence collection. This method is not only inefficient, but also has the disadvantages of high labor costs and untimely evidence collection, which is difficult to meet the needs of modern urban traffic management. At the same time, traditional photo evidence collection cannot obtain evidence of the overall environment, causing some drivers to question the incomplete photos of evidence collection, thus causing toll disputes.

[0003] In response to the above problems, the inventor has proposed a parking extended evidence photo evidence collection system and evidence collection method (Announcement No.: CN116504071B), which sets up video poles in front of and behind the parking space to take photos and merge them into a long photo to prove that the vehicle with the license plate is parked in the corresponding parking space, forming a complete chain of evidence. However, this method requires at least two cameras to be configured in each parking space, and the hardware laying cost is too high. Moreover, the rigid splicing of the photos taken by the front and rear video poles may cause large distortion of the evidence photos, making it difficult to use them as reliable supporting materials for parking charges.

[0004] At present, with the rapid development of big data, artificial intelligence and intelligent hardware technology, new solutions have been provided for on-street parking management. In particular, the maturity and application of drone technology has provided a more efficient and intelligent means for on-street parking evidence collection. However, drone evidence collection has the defect of insufficient battery life. Most drones rely on lithium batteries for power supply. When used for on-street parking evidence collection, the battery life is usually between 30 minutes and 1 hour, which greatly limits its ability to perform long-term tasks. Especially in the process of evidence collection, drones need to hover for a long time to shoot or track targets, and short battery life has become its significant defect. At the same time, rain and wind and sand may cause damage to charging equipment, making outdoor charging of drones face many challenges. Traditional drone evidence collection methods are often difficult to be comprehensive, timely and accurate when faced with these complex situations, further exacerbating the difficulty of management.

[0005] Therefore, it is necessary to provide a drone on-road parking evidence collection system and method to solve the problems existing in the prior art. Summary of the invention

[0006] In response to the problems in the related technology, the present invention proposes a drone on-street parking space evidence collection system and method to solve the problems of insufficient battery life of existing drone on-street parking space evidence collection, difficulty in coping with outdoor charging conditions in rainy weather, and possible distortion of evidence photos related to the overall environment, making it difficult to use them as a basis for charging.

[0007] The technical solution of the present invention is implemented as follows: a drone on-road parking space evidence collection system, comprising a parking area arranged on the roadside, the parking area comprising a plurality of parking spaces sequentially distributed along the extension direction of the road; a lighting module is arranged near the parking space, the lighting module comprises a lamp pole, and a lamp head, a solar panel, an energy storage battery and a control assembly arranged on the lamp pole; the control assembly is respectively connected to the lamp head, the solar panel and the energy storage battery; the lamp pole is also provided with a flight evidence collection device, the flight evidence collection device comprises a drone and an apron;

[0008] The drone is provided with a camera module, a flight battery and a central control unit; the central control unit is connected to the camera module and the flight battery respectively; the camera module is configured to photograph the parked vehicle in the parking space; the flight battery is used for energy supply; when the parked vehicle is parked in the parking space, the drone approaches the parked vehicle and circles around the parked vehicle; the camera module takes panoramic photos of the parked vehicle for evidence collection and transmits them to the central control unit;

[0009] The apron includes a parking platform and a rain shield, the rain shield is used to cover the parking platform; the parking platform is provided with a public pole that can be raised and lowered and hidden; the public pole is connected to the energy storage battery through the control assembly; the lower part of the drone camera module is provided with a female pole, and the female pole is connected to the flight battery through the central control unit; when the drone is parked on the parking platform, the public pole rises and connects with the female pole of the drone; the control assembly and the central control unit of the drone are connected through the cooperation of the public pole and the female pole to obtain power and transmit data; the control assembly is built with a storage module for storing panoramic evidence photos transmitted from the drone central control unit.

[0010] The present invention sets the apron where the drone is parked on the lighting module. The drone is connected to the public pole that can be raised and lowered and hidden on the apron through the female pole to obtain power supply and data transmission, realize fast charging, effectively extend the endurance of the drone, and solve the problem of insufficient endurance. In addition, the drone is equipped with a camera module, which can circle around the parked vehicle to obtain panoramic evidence photos. The camera range of the panoramic evidence photos extends from the front of the parked vehicle to the rear of the parked vehicle, linking the parking space, the parked vehicle and the surrounding environment to form a complete chain of evidence, which improves the accuracy and reliability of evidence collection and reduces the distortion problem caused by photo splicing.

[0011] As a further improvement of the above scheme, when the drone takes photos of the parked vehicle, the drone orbits along an arc with the parked vehicle as the center; the camera module shoots multiple points in the radial direction of the orbiting trajectory to obtain the panoramic evidence photo; the camera range of the panoramic evidence photo extends from the front of the parked vehicle to the rear of the parked vehicle. The camera module shoots multiple points in the radial direction of the orbiting trajectory, associates the parking space, the parked vehicle and the surrounding environment, and forms a complete chain of evidence. This chain of evidence can be a strong evidence material for parking charges, proving that the vehicle is indeed parked in this parking space and generates fees, so as to achieve the purpose of complete evidence collection and avoid the occurrence of parking fee disputes.

[0012] As a further improvement of the above scheme, when the camera module shoots at multiple points, it shoots a first panoramic fragment photo at the first point; when the drone circles to the second point, the camera module uses the first panoramic fragment photo as the reference virtual scene, and performs docking verification with the real scene facing the second point, and shoots and obtains the second panoramic fragment photo; repeats the shooting process until the last point, and the photo obtained at the last point is the panoramic evidence photo. The rigid splicing of traditional evidence photos may cause large distortion of the evidence photos, making it difficult to serve as reliable supporting material for parking fees. This evidence system uses the panoramic fragment shot at the first point as the reference virtual scene, partially overlaps it with the real scene at the next point, and shoots fixed evidence materials. There is no need for image processing and splicing, and no large distortion will occur, ensuring the effectiveness and reliability of the evidence materials.

[0013] As a further improvement of the above scheme, when docking and verifying a certain point, the reference virtual scene is partially overlapped with the real scene of the point; the overlapping part is taken as the verification area, and the overlap rate of the two is verified; if the overlap rate meets the preset threshold, a panoramic view fragment photo of the point is taken. By setting the overlapping part as the verification area, it is ensured that the panoramic view evidence photos taken will not have large distortion, and the quality of the evidence photos is guaranteed.

[0014] As a further improvement of the above scheme, each berth is also equipped with a geomagnetic sensor, which is connected to the central control unit of the drone; when a parked vehicle enters or leaves the berth, the geomagnetic sensor sends a sensing signal to the central control unit, which controls the drone to fly to the corresponding berth to take photos and collect evidence. In order to better feedback the usage status of each berth, a geomagnetic sensor is further configured on each berth, which can accurately monitor the berth status and optimize the use and allocation of each berth.

[0015] As a further improvement of the above scheme, a concave cavity is provided in the middle of the parking platform, the top of the concave cavity is open, and a cover mechanism is provided at the opening; when the public pole rises, the cover mechanism opens to expose the public pole outside the parking platform; when the public pole descends, the cover mechanism closes to completely cover the public pole. The apron is provided with a rain shield and a public pole that can be raised and lowered to ensure normal charging and use in rainy weather, enhancing the outdoor adaptability and stability of the system.

[0016] As a further improvement of the above scheme, the cover closing mechanism includes a left cover body and a right cover body, each of which is connected to a swing lever group and is hinged on the inner wall of the cavity through the corresponding swing lever group; the public pole is arranged on the seat plate, and the seat plate is powered by a power push rod arranged on the inner wall of the cavity; each swing lever is fixedly connected to a connecting rod assembly at one end away from the cover body, and the connecting rod assembly is transmission-connected with the seat plate; when the seat plate moves up or down, each connecting rod assembly drives the corresponding swing lever group to rotate, and the left cover body and the right cover body move away from or towards each other. The cover closing mechanism is configured to ensure that the public pole is buried in the apron after charging is completed, to avoid being affected by rain and wind and sand, and to eliminate safety risks such as leakage; in addition, a single power push rod can synchronously drive the public pole to move up and the cover closing mechanism to open, and the structure is exquisite and reliable.

[0017] As a further improvement of the above scheme, the swing rod group includes a first swing rod and a second swing rod, the upper end of each swing rod is hinged to the two ends of the corresponding cover body; the lower end of each swing rod is hinged to the inner wall of the concave cavity, and the hinge points are on the same horizontal line; the hinge points at both ends of the first swing rod and the hinge points at both ends of the second swing rod are connected to form a parallelogram. The ingenious design of connecting the four points to form a parallelogram not only ensures that the cover body can maintain parallel movement when swinging, avoids the cover body from having too large a swing amplitude during the swinging process, but also ensures the stability and balance of the cover body during the swinging process.

[0018] A method for collecting evidence of an unmanned aerial vehicle on-road parking space is applied to the unmanned aerial vehicle on-road parking space collection system as described above, wherein a geomagnetic sensor is buried in each parking space, and the geomagnetic sensor is connected to a central control unit of the unmanned aerial vehicle; the method comprises the following steps:

[0019] S1. When a parked vehicle enters a parking space, the geomagnetic sensor sends a sensing signal to the central control unit, and the central control unit controls the drone to fly to the corresponding parking space to take photos and collect evidence;

[0020] S2. When the parked vehicle is parked, the drone orbits along an arc with the parked vehicle as the center; the camera module on the drone shoots multiple points in the radial direction of the orbiting trajectory to obtain the panoramic evidence photos;

[0021] S3, the UAV is flown and parked on the parking platform, the male pole is raised and connected to the female pole of the UAV; the control assembly and the central control unit of the UAV are connected through the cooperation of the male pole and the female pole to obtain power and transmit data; the control assembly is built with a storage module for storing the panoramic forensic photos transmitted from the central control unit of the UAV;

[0022] S4. When the parked vehicle leaves the parking space, the geomagnetic sensor sends a sensing signal to the central control unit, and the central control unit controls the drone to fly to the corresponding parking space to take photos and collect evidence at a single point, and S3 is repeated.

[0023] Preferably, in S2, when the camera module performs shooting at multiple points, a first panoramic fragment photo is taken at the first point; when the drone circles to the second point, the camera module uses the first panoramic fragment photo as a reference virtual scene, performs docking verification with the real scene facing the second point, and shoots to obtain the second panoramic fragment photo; the shooting process is repeated until the last point, and the photo obtained at the last point is the panoramic evidence photo.

[0024] Beneficial effects of the present invention:

[0025] (1) Improved endurance: The apron where the drone is parked is set on the lighting module. The drone is connected to the hidden public pole on the apron through the female pole to obtain power and transmit data, achieving fast charging, effectively extending the drone's endurance and solving the problem of insufficient endurance.

The panoramic evidence photos are transmitted while charging and supplying energy, ensuring the security and reliability of the data, which is convenient for use as a basis for charging.
