Description

Technical Field

[0001] The present invention belongs to the technical field of parking charging, and particularly relates to an in-road berth evidence collection system and method for drones. Background Art

[0002] With the rapid advancement of urbanization, the number of private cars in cities has increased sharply, and the in-road parking resources have become increasingly tense, becoming a key factor restricting urban traffic flow and residents' quality of life. Reasonably planning in-road parking berths and improving the utilization efficiency of berths are of great significance for alleviating the parking difficulty problem and optimizing the urban traffic environment. However, the current management of in-road parking berths mainly relies on manual inspections, video pile evidence collection, and patrol vehicle evidence collection. This method not only has low efficiency but also has disadvantages such as high labor costs and untimely evidence collection, making it difficult to meet the needs of modern urban traffic management. At the same time, traditional photo evidence collection cannot achieve evidence collection of the overall environment, resulting in some drivers questioning the incomplete photos of evidence collection, thus causing charging disputes.

[0003] In response to the above problems, the inventor once proposed an evidence collection system and method for parking extended evidence collection photos (Publication No.: CN116504071B). By setting video piles in front of and behind the parking space to take photos and combining them into a long photo to prove that the vehicle with the license plate is parked in the corresponding parking space, a complete evidence chain is formed. 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 piles may cause large distortions in the evidence collection photos, making it difficult to be used as reliable evidence for parking charges.

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

[0005] Therefore, it is necessary to provide an in-road berth evidence collection system and method for drones 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 to the above solution, when the drone takes pictures of parked vehicles, the drone orbits around the parked vehicle along an arc line; the imaging module takes pictures at multiple points along its radial direction on the orbiting trajectory to obtain the panoramic evidence photos; the imaging range of the panoramic evidence photos extends from the front of the parked vehicle to the rear of the parked vehicle. The imaging module takes pictures at multiple points along its radial direction on the orbiting trajectory, correlates the berth, the parked vehicle and the surrounding environment, and forms a complete evidence chain. This evidence chain can be strong evidence for parking charges, proving that the vehicle has indeed parked in this berth and generated fees, achieving the purpose of complete evidence collection and avoiding parking charge disputes.

[0012] As a further improvement to the above solution, when the imaging module takes pictures at multiple points, it takes the first panoramic segment photo at the first point; when the drone orbits to the second point, the imaging module uses the first panoramic segment photo as the reference virtual scene and docks and calibrates it with the real scene facing the second point to take and obtain the second panoramic segment photo; repeat the taking 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 distortions in the evidence photos and it is difficult to be used as reliable supporting materials for parking charges. This evidence collection system uses the panoramic segment taken at the previous point as the reference virtual scene, partially overlaps it with the real scene at the next point and takes and fixes the evidence materials, without image processing and splicing, and will not produce large distortions, ensuring the effectiveness and reliability of the evidence materials.

[0013] As a further improvement to the above solution, when docking and calibrating at a certain point, the reference virtual scene and the real scene at this point are partially overlapped; the overlapping part is taken as the calibration area to perform the overlap rate calibration of the two; if the overlap rate meets the preset threshold, then take and obtain the panoramic segment photo at this point. By setting the overlapping part as the calibration area, it is ensured that the panoramic evidence photos taken will not produce large distortions and the quality of the evidence photos is guaranteed.

[0014] As a further improvement to the above solution, geomagnetic sensors are also buried on each berth, and the geomagnetic sensors are connected to the central control unit of the drone; when a parked vehicle enters or leaves the berth, the geomagnetic sensor sends an induction signal to the central control unit, and the central control unit controls the drone to fly to the corresponding berth for photo evidence collection. In order to better feedback the usage status of each berth, further, geomagnetic sensors are configured on each berth, and the status of the berth can be accurately monitored through the geomagnetic sensors, optimizing the usage allocation of each berth.

[0015] As a further improvement of the above solution, a concave cavity is provided in the middle of the parking platform. The top of the concave cavity is open, and a closing cover mechanism is provided at the opening. When the male pole rises, the closing cover mechanism opens to expose the male pole outside the parking platform. When the male pole descends, the closing cover mechanism closes to completely shield the male pole. The apron is provided with a rain shield and a male pole that can be lifted and hidden, ensuring normal charging and use even in rainy weather, and enhancing the outdoor adaptability and stability of the system.

[0016] As a further improvement of the above solution, the closing cover mechanism includes a left cover body and a right cover body. Each cover body is connected with a swing rod group and is hinged on the inner side wall of the concave cavity through the corresponding swing rod group. The male pole is arranged on a seat plate, and the seat plate is powered by a power push rod arranged on the inner side wall of the concave cavity. Each swing rod is fixedly connected with a connecting rod assembly at the end far away from the cover body, and the connecting rod assembly is in transmission connection with the seat plate. When the seat plate moves up or down, each connecting rod assembly drives the corresponding swing rod group to rotate, and the left cover body and the right cover body move away from or towards each other. The configuration of the closing cover mechanism ensures that the male pole is buried in the apron after charging is completed, avoiding the influence of rain, sand and wind, and eliminating safety risks such as electric leakage. In addition, through a single power push rod, the male pole can be driven to move up synchronously, and the closing cover mechanism can be opened, with a delicate and reliable structure.

[0017] As a further improvement of the above solution, the swing rod group includes a first swing rod and a second swing rod. The upper ends of each swing rod are respectively hinged to both ends of the corresponding cover body. The lower ends of each swing rod are respectively hinged on the inner side wall of the concave cavity, and the hinge points are on the same horizontal line. The four connection points of the two ends of the first swing rod and the two ends of the second swing rod form a parallelogram. The ingenious design of the four connection points forming a parallelogram not only ensures that the cover body can move parallelly during swinging, avoiding excessive swing space of the cover body during swinging, but also ensures the stability and balance of the cover body during swinging.

[0018] A method for a drone to obtain evidence of on-road parking spaces is applied to the above-mentioned drone on-road parking space evidence obtaining system. Geomagnetic sensors are buried in each parking space, and the geomagnetic sensors are connected to the central control unit of the drone. It includes the following steps:

[0019] S1. When a parked vehicle enters the parking space, the geomagnetic sensor sends an induction signal to the central control unit, and the central control unit controls the drone to fly to the corresponding parking space for taking pictures and obtaining evidence.

[0020] S2. After the parked vehicle has completed parking, the drone orbits along an arc line with the parked vehicle as the center. The camera module on the drone takes pictures at multiple points in the radial direction of the orbiting trajectory to obtain the panoramic evidence pictures.

[0021] S3. The drone flies and parks on the parking platform, and the male pole rises to connect with the female pole of the drone; between the control assembly and the central control unit of the drone, power is taken and energy is supplied, and data is transmitted through the cooperation connection between the male pole and the female pole; the control assembly is internally provided with a storage module for storing the panoramic evidence-taking photos transmitted from the central control unit of the drone.

[0022] S4. When the parked vehicle leaves the berth, the geomagnetic inductor sends an induction signal to the central control unit, and the central control unit controls the drone to fly to the corresponding berth for single-point photographing and evidence-taking, and repeats S3.

[0023] Preferably, in S2, when the camera module takes multiple-point shots, it takes the first panoramic segment photo at the first point; when the drone orbits to the second point, the camera module uses the first panoramic segment photo as a reference virtual scene to dock and verify with the real scene facing the second point, and takes and obtains the second panoramic segment photo; the shooting process is repeated until the last point, and the photo obtained at the last point is the panoramic evidence-taking photo.

[0024] Advantages of the present invention:

[0025] (1) Improvement in endurance: The apron where the drone is parked is arranged on the lighting module. The drone is connected to the retractable and hidden male pole on the apron through the female pole for power taking, energy supply and data transmission, realizing fast charging, effectively extending the endurance time of the drone, and solving the problem of insufficient endurance; at the same time, the control assembly is internally provided with a storage module for storing the panoramic evidence-taking photos transmitted from the central control unit of the drone, and the panoramic evidence-taking photos are transmitted while charging and supplying energy, ensuring the security and reliability of the data and facilitating it to be used as a charging basis.

[0026] (2) All-weather adaptability: The apron is provided with a rain shield and a retractable and hidden male pole to ensure normal charging and use even in rainy weather, enhancing the outdoor adaptability and stability of the system.

[0027] (3) Reliable evidence-taking: The drone is equipped with a camera module, which can take circumferential photos of the parked vehicle. The shooting range of the panoramic evidence-taking photo extends from the front of the parked vehicle to the rear of the parked vehicle, associating the berth, the parked vehicle and the surrounding environment to form a complete evidence chain, improving the accuracy and reliability of evidence-taking and reducing the distortion problem caused by photo splicing.

[0028] (4) Intelligent control and reduction of hardware installation costs: The central control unit of the drone is connected to the camera module and the flight battery to achieve intelligent control. The drone can automatically approach the parked vehicle, reducing the complexity and error rate of manual operation. At the same time, based on the drone's ability to hover and shoot at multiple points, there is no need to configure multiple camera modules, effectively reducing the hardware installation cost for evidence collection, which is economical and reliable.

[0054] The apron 22 includes a parking platform 221 and a rain shield 222. The rain shield 222 is used to shield the parking platform 221. The parking platform 221 is provided with a male electrode 31 that can be lifted and hidden. The male electrode 31 is connected to a storage battery through a control assembly. The lower part of the camera module 212 of the UAV 21 is provided with a female electrode 32, and the female electrode 32 is connected to a flight battery through a central control unit. When the UAV 21 is parked on the parking platform 221, the male electrode 31 rises to connect with the female electrode 32 of the UAV 21. Between the control assembly and the central control unit of the UAV 21, through the cooperation connection of the male electrode 31 and the female electrode 32, power taking, power supply and data transmission are carried out. The control assembly is internally provided with a storage module for storing panoramic evidence-taking photos transmitted from the central control unit of the UAV 21. In this embodiment, a concave cavity A1 is provided in the middle of the parking platform 221. The top of the concave cavity A1 is open, and a cover closing mechanism 5 is provided at the opening. When the male electrode 31 rises, the cover closing mechanism 5 opens to expose the male electrode 31 outside the parking platform 221. When the male electrode 31 descends, the cover closing mechanism 5 closes to completely shield the male electrode 31.

In this embodiment, the central control unit and the control assembly can both adopt control modules such as single-chip microcomputers.

[0055] In this embodiment, the cover closing mechanism 5 includes a left cover body 51a and a right cover body 51b. Each cover body is connected with a swing rod group 52 and is hinged on the inner side wall of the concave cavity A1 through the corresponding swing rod group 52. The male electrode 31 is arranged on a seat plate 61, and the seat plate 61 is provided with power by a power push rod 62 arranged on the inner side wall of the concave cavity A1. Each swing rod is fixedly connected with a connecting rod assembly 53 at the end far from the cover body, and the connecting rod assembly 53 is in transmission connection with the seat plate 61. When the seat plate 61 moves up or down, each connecting rod assembly 53 drives the corresponding swing rod group 52 to rotate, and the left cover body 51a and the right cover body 51b move away from or towards each other. The configuration of the cover closing mechanism 5 ensures that the male electrode 31 is buried in the apron 22 after charging is completed, avoiding the influence of rain, sand and wind, and eliminating safety risks such as electric leakage. In addition, through a single power push rod 62, the male electrode 31 can be driven to move up synchronously, and the cover closing mechanism 5 can be opened, and the structure is delicate and reliable. Specifically, the power push rod 62 can adopt an electric push rod.

The upper ends of the swing rods are respectively hinged to both ends of the corresponding cover body; the lower ends of the swing rods are respectively hinged to the inner side wall of the cavity A1, and the hinge points are on the same horizontal line; the hinge points at both ends of the first swing rod 521 and the hinge points at both ends of the second swing rod 522 form a parallelogram when connected by four lines. The ingenious design of forming a parallelogram by the four connected lines not only ensures that the cover body can move parallelly during swinging, avoiding excessive swing space of the cover body during the swinging process, but also ensures the stability and balance of the cover body during the swinging process. The connecting rod assembly 53 includes a first connecting rod 531, a second connecting rod 532 and a guiding arc plate 54; wherein, one end of the first connecting rod 531 is fixedly connected to the first swing rod 521, the other end is hinged to the second connecting rod 532, and is connected to the seat plate 61 through the second connecting rod 532. The guiding arc plate 54 is provided with a rail groove, which provides an accurate guiding function for the hinge points of the first connecting rod 531 and the second connecting rod 532 in the connecting rod assembly 53, ensuring that the hinge points always move along a predetermined trajectory during the movement process, thereby ensuring the reliable operation of the connecting rod assembly 53.

[0057] In this embodiment, when the drone 21 takes pictures of the parked vehicle T1, the drone 21 orbits along an arc line with the parked vehicle T1 as the center; the camera module 212 takes pictures at multiple points 41 in the radial direction along the orbiting trajectory to obtain the panoramic evidence photos; the shooting range of the panoramic evidence photos extends from the front of the parked vehicle T1 to the rear of the parked vehicle T1. The camera module 212 takes pictures at multiple points 41 in the radial direction along the orbiting trajectory, associates the berth B2, the parked vehicle T1 and the surrounding environment, and forms a complete evidence chain. This evidence chain can be used as strong evidence for parking charges, proving that the vehicle has indeed parked in this berth B2 and generated fees, achieving the purpose of complete evidence collection and avoiding the occurrence of parking charge disputes. Specifically, 5 points 41 are used for evidence collection in this embodiment, and the points 41 are evenly distributed at intervals along the semi-circular arc line.

[0058] In this embodiment, when the camera module 212 takes pictures at multiple points 41, it takes the first panoramic segment photo at the first point 41. When the drone 21 orbits to the second point 41, the camera module 212 uses the first panoramic segment photo as the reference virtual scene 42 and performs docking verification with the real scene 43 facing the second point 41, and takes the second panoramic segment photo. The shooting process is repeated until the last point 41, and the photo obtained at the last point 41 is the panoramic evidence photo. The rigid splicing of traditional evidence photos may cause large distortions in the evidence photos, making it difficult to use as reliable supporting materials for parking fees. This evidence system takes the panoramic segment taken at the previous point 41 as the reference virtual scene 42, partially overlaps it with the real scene 43 at the next point 41, and shoots and fixes the evidence materials, without image processing and splicing, and will not produce large distortions, ensuring the effectiveness and reliability of the evidence materials.

[0059] In this embodiment, when performing docking verification at a certain point 41, the reference virtual scene 42 is partially overlapped with the real scene 43 at this point 41. The overlapping part is taken as the verification area 44 to perform the coincidence rate verification of the two. If the coincidence rate meets the preset threshold, the panoramic segment photo at this point 41 is taken. By setting the overlapping part as the verification area 44, it is ensured that the panoramic evidence photo taken will not produce large distortions and the quality of the evidence photo is guaranteed. Specifically, the verification area 44 can be circular, and the preset threshold can be 65% - 75%, that is, when the coincidence rate meets 65% - 75%, photo evidence is taken to obtain the evidence photo at this point 41.

[0060] In this embodiment, geomagnetic sensors D1 are also buried on each berth B2, and the geomagnetic sensors D1 are connected to the central control unit of the drone 21. When the parked vehicle T1 enters or leaves the berth B2, the geomagnetic sensor D1 sends an induction signal to the central control unit, and the central control unit controls the drone 21 to fly to the corresponding berth B2 for photo evidence collection. In order to better feedback the usage status of each berth B2, further, geomagnetic sensors D1 are configured on each berth B2. Through the geomagnetic sensors D1, the status of the berth B2 can be accurately monitored, and the use and allocation of each berth B2 can be optimized.

[0066] In the present invention, the apron 22 where the UAV 21 is parked is arranged on the lighting module 1, and the UAV 21 is connected to the liftable and hidden male pole 31 on the apron 22 through the female pole 32 for power taking, energy supply and data transmission, realizing fast charging, effectively extending the endurance time of the UAV 21, and solving the problem of insufficient endurance.
