Description

Technical Field

[0001] The present invention relates to the technical field of on-street parking management, and in particular to a method and device for collecting on-street parking data using a wiring-free camera. Background Art

[0002] Compared with parking lot management, on-street parking (roadside parking) lacks the corresponding entrance and exit vehicle information recognition equipment and cannot complete fully automatic parking timing management. It requires manual observation or collection of parking space detection equipment (such as geomagnetism, etc.) to detect changes in vehicles in parking spaces and manually record the vehicle license plate numbers in parking spaces. This method wastes manpower and is inefficient.

[0003] Existing roadside parking recognition systems generally adopt the following forms: 1) Use parking space inspection management personnel to inspect: Parking space inspection managers inspect parking spaces at fixed time intervals (e.g. 15 minutes) and record vehicle entry and exit times, charges, etc. This method requires a lot of manpower, is inefficient, and has inaccurate billing.

[0004] 2) Geomagnetic parking fee form: The geomagnetic parking fee collection method is to set up a geomagnet under the road surface corresponding to each parking space. It is easy to install, but the geomagnetism can only identify whether there is a vehicle in the parking space, and cannot identify the license plate number of the vehicle in the parking space. Therefore, it is also necessary to cooperate with manual photography to keep evidence, so as to obtain the corresponding license plate number of the corresponding parking space, and manage and charge on this basis. It not only requires a lot of manpower, but also requires large-scale reconstruction of the existing road surface, such as excavating the existing road surface, affecting traffic during construction, etc. It not only requires a large amount of money but also requires a lot of manpower cooperation, and the actual detection accuracy is not ideal.

[0005] 3) Video parking fee collection method: The video pile parking fee payment method uses a video pile set in a corner of the parking space. The video monitors the vehicles entering and leaving, and can automatically complete the vehicle parking and self-service payment. However, this method has the following problems: (1) Easy to damage: Since the video poles are generally set on one side of the parking space along the length direction, the height is usually 80cm-120cm, which is relatively short. Therefore, the video poles are easily damaged during parking. In addition, there are also cases of artificial destruction of video poles to evade payment. (2) Easy to be blocked: Because it is relatively short, it is easy for some obstructions to be set up on it artificially or accidentally, resulting in the inability to identify parking, etc.; (3) High cost: Video poles are integrated devices that combine multiple devices, so they are very expensive. Once damaged, the maintenance cost is high.

[0006] (4) Landscape impact: Each parking space corresponds to a video pole, and a large number of video poles have a great impact on the urban landscape.

[0007] 4) High-position video charging model: High-position video cameras are deployed on the horizontal arm of the pole on the same side of the on-street parking spaces, with a height of 6-8 meters. Usually, two cameras are installed at one point to shoot 6-8 parking spaces. The images of the parking areas are collected through video, and the vehicle information in the images is identified to realize the billing and management of on-street parking spaces. However, this method has the following problems: (1) Since the camera is installed at a high position and has a horizontal arm, the pole foundation will be large and the construction cost will be high; (2) The camera is powered by the mains, and the pole location requires road breaking to obtain power. This is very costly, and the road breaking and restoration work will damage the municipal links and affect the beauty of the urban environment. (3) Due to the high deployment cost, it is difficult to promote in areas with limited financial resources; 5) No-wiring high-position snapshot charging mode: The high-position snapshot camera is deployed on the pole or the borrowed pole (street light pole) on the opposite side of the on-street parking space, with a height of 3-4 meters. Usually, two cameras are installed at one point to capture 3-5 parking spaces. By capturing images of the parking area and identifying vehicle information in the image, on-street parking space billing and management are realized. Although this solution solves the problem of high-position video solutions with high construction costs and damage, this method has the following problems: (1) The camera installation position needs to ensure that the license plate of the vehicle being photographed is not likely to be blocked by nearby vehicles. Therefore, the requirements for the deployment location are high, and the project deployment design will be very restrictive, making the design difficult. (2) Due to the obstruction of vehicles near the parking spaces, the shooting angle cannot be too large, resulting in a camera at one installation point only being able to shoot 3-4 parking spaces, or even less, which is far less than the 6-8 parking spaces that the high-position video solution can shoot. As a result, a large number of poles are required, which has a significant impact on the city's appearance and is not conducive to the deployment and advancement of the project. Summary of the invention

[0008] The purpose of the present invention is to provide a method and device for collecting on-street parking data using a wiring-free camera in view of the problems and shortcomings described in the background technology.

[0009] A device for collecting on-street parking data using a wiring-free camera, comprising: At least 2 cameras, 2 cameras are installed 3-4 meters away from the berth on the opposite side of the berth or on the borrowed pole, and each 2 cameras can shoot 6-8 berths; The power supply module is connected with the communication module, the storage module and the two camera circuits to provide power to the communication module and the camera; The storage module is connected to the camera circuit and is used to store the image data captured by the camera; The communication module is connected to the storage module circuit and is used to upload the collected image data to the server; A power management module, which is connected to the communication module, storage module, camera, and power supply module circuits. The power management module is used to control the communication module, storage module, camera, and power supply module to sleep or power off; The server is connected to the communication module, and is used to receive and send the image data processed by the server.

[0010] A method for collecting on-street parking data using a wiring-free camera comprises the following steps: S1: Two cameras collect and shoot image data of the monitored area at a high frequency; S2: After each camera has collected 2 minutes of image data, the camera uploads the last frame of the image collected through the communication module for server recognition; S3: The server uses an image recognition algorithm to identify changes in vehicles in the pre-configured parking area in the image. When a vehicle entry event is identified, the license plate recognition algorithm is used to collect the license plate information of the parking vehicle if there is no obstruction by nearby vehicles. When the vehicle changes, the server will obtain all image data from the previous cycle in the storage module, and accurately determine the vehicle's entry or departure time by tracking the vehicle trajectory of the changed vehicle. If the license plate cannot be collected statically, the license plate information can also be collected during the vehicle's entry and departure process. S4: The server performs cloud recognition on the collected images and uses image recognition algorithms to perform on-street parking fee collection and parking space management on the recognition result data.

[0011] Beneficial effects of the present invention: The image server can collect the changes of vehicles in the parking spaces. When a vehicle entry event is identified, the license plate information of the parking vehicle is collected using the license plate recognition algorithm if there is no obstruction from nearby vehicles. When the vehicle changes, the server will obtain all the image data of the previous cycle in the storage module, and accurately determine the vehicle's entry or departure time by tracking the vehicle's trajectory. If the license plate cannot be collected statically, the license plate information can also be collected during the vehicle's entry and departure process. By charging the device through solar energy, in most environments with good solar energy, the device can be powered without maintenance; at the same time, benefiting from the low power consumption characteristics, the use of large-capacity lithium batteries can greatly enhance the device's ability to withstand continuous rainy days while being solar-powered.
