Attached Figure Description
[0033] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0034] Figure 1 This is a structural diagram of a smart park vehicle recognition system provided by the present invention;
[0035] Figure 2 The present invention provides a flowchart of the operation of a smart park vehicle recognition system. Detailed Implementation
[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0037] The purpose of this invention is to provide a smart park vehicle identification system that can improve the efficiency of vehicle model monitoring.
[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0039] like Figures 1 to 2 As shown, a smart park vehicle recognition system includes: a vehicle image monitoring component 1, a vehicle model comprehensive management component 2, a vehicle database component 3, a license plate data acquisition component 4, and a vehicle feature model calculation component 5.
[0040] The vehicle image monitoring component is connected to the vehicle model integrated management component. The vehicle image monitoring component manages vehicle image size and vehicle image acquisition information, and sends the vehicle image size and vehicle image acquisition information to the vehicle model integrated management component. The vehicle image size includes vehicle model completeness. The vehicle image acquisition information includes acquisition time, acquisition frequency, and vehicle model color information. The vehicle image monitoring component includes vehicle image size management and vehicle image acquisition information management. Among them, vehicle image size management refers to the management of vehicle model completeness files. The correspondence between vehicle image monitoring and vehicle model sequence can be determined through vehicle image acquisition information, including acquisition time, acquisition frequency, and vehicle model color information.
[0041] The vehicle model integrated management component is also connected to the vehicle database component. The vehicle model integrated management component is used to send control commands to the vehicle database component. The control commands include reassembling the vehicle image size and controlling vehicle image monitoring based on the vehicle image acquisition information. The reassembly vehicle image size has feature values. The feature values include vehicle model name, vehicle image monitoring time list identifier, park name, monitoring park area, vehicle integrity, and acquisition frequency. The vehicle model integrated management component is mainly used in this system for vehicle model package reassembly and vehicle image monitoring control.
[0042] The vehicle database component is also connected to the license plate data acquisition component. The vehicle database component is used to execute control operations according to the control instructions to realize vehicle image monitoring. The vehicle database component executes corresponding control operations according to the data and commands sent by the vehicle model integrated management component.
[0043] The license plate data acquisition component is also connected to the vehicle feature model calculation component. The license plate data acquisition component is used to acquire vehicle image monitoring images implemented by the vehicle database component and send the vehicle image monitoring images to the vehicle feature model calculation component. The vehicle feature model calculation component is used to generate an acquisition document based on the vehicle image monitoring images and the vehicle image acquisition information, and to monitor the vehicle model in the vehicle image monitoring based on the acquisition document. The license plate data acquisition component is used to acquire the screen images in the vehicle database component; the vehicle feature model calculation component generates the final acquisition document based on the acquired image information and vehicle image acquisition information. The workflow of a smart park vehicle recognition system includes vehicle image size and vehicle image acquisition and distribution, vehicle model package reassembly, scheduling generation, vehicle model time image acquisition, image upload, and data analysis.
[0044] Vehicle model and vehicle image acquisition and distribution:
[0045] After importing a new vehicle model file, the vehicle image monitoring component will automatically distribute the information to the corresponding monitoring location vehicle model integrated management component based on the monitoring location of the vehicle model. The vehicle image acquisition information will also be automatically sent to the corresponding monitoring location vehicle model integrated management component. At the same time, the vehicle image monitoring component will send the vehicle image acquisition information to the vehicle feature model calculation component for subsequent generation of acquisition documents.
[0046] Vehicle model package reassembly:
[0047] 1. Data Acquisition Algorithm Generation
[0048] After receiving vehicle image acquisition information from the vehicle image monitoring component, the vehicle model integrated management component generates a unique feature value for each vehicle model based on the vehicle image monitoring frequency information and by applying currently mature acquisition algorithms. This feature value includes: vehicle model name, vehicle entry / exit frequency, park name, monitored park area, vehicle integrity, and acquisition frequency.
[0049] 2. Vehicle model DCP repackage
[0050] After receiving the DCP file from the vehicle image monitoring component, the vehicle model integrated management component adds feature values to each frame of the original DCP data by calling the mature OpenCV algorithm, and finally outputs a new vehicle model DCP file.
[0051] 3. Schedule generation
[0052] After receiving vehicle image acquisition information, the vehicle model integrated management component automatically generates a monitoring location schedule based on the system scheduling information and sends the schedule to the time server of the corresponding hall; the POS schedule is the demand setting manually arranged by the demand personnel or other operators at the end user.
[0053] 4. Vehicle model time image capture
[0054] After the scheduling begins, the time server projects the image onto the computer screen via the requesting machine. A unique feature value will then appear at a designated location on the vehicle model screen. During this implementation, the time frame of the image needs to be recorded for use by the subsequent vehicle feature model calculation component.
[0055] Currently, the process of recording vehicle model can be done using the following two methods:
[0056] 1) Use digital equipment to capture images of vehicle models with characteristic values through manual shooting.
[0057] 2) Automatic shooting equipment is installed on the barrier to automatically capture images of the barrier screen.
[0058] 5. Image Upload
[0059] 1) The photos are uploaded to the designated vehicle feature model calculation component by manually taking pictures.
[0060] 2) By installing an automatic shooting device on the gear lever, the automatic shooting device can automatically upload the captured photos to the designated vehicle feature model calculation component.
[0061] 6. Data Analysis
[0062] After collecting the uploaded images with feature values, the vehicle feature model calculation component calls the feature value recognition program to read the information contained in the feature values and save the information to the vehicle model color database.
[0063] The vehicle image acquisition information sent by the vehicle image monitoring component to the vehicle feature model calculation component already exists in the vehicle model color database; the vehicle image monitoring component compares the information in the identified feature values with the local vehicle image acquisition information.
[0064] Finally, the vehicle feature model calculation component will automatically generate a detection document based on the detection results. This detection document will include the images used in the process of generating the monitoring document as document attachments. Vehicle model manufacturers or vehicle model operators can directly understand the vehicle model recognition status through this document.
[0065] like Figure 2 As shown, a smart park vehicle recognition system includes:
[0066] Step A1: Manage vehicle image size and vehicle image acquisition information, and send the vehicle image size and vehicle image acquisition information to the vehicle model integrated management component; the vehicle image size includes vehicle model completeness; the vehicle image acquisition information includes acquisition time, acquisition frequency, and vehicle model color information.
[0067] Following step A1, the method further includes: obtaining the vehicle image monitoring requirement settings of the end user; the vehicle image monitoring requirement settings include vehicle image monitoring frequency information, vehicle image monitoring requirement time, and vehicle image monitoring requirement duration; generating feature values based on the vehicle image monitoring requirement settings; embedding the feature values into the vehicle image size, and recombining the vehicle image size to determine the vehicle image size with feature values.
[0068] Step A2: Send a control command to the vehicle database component; the control command includes reassembling the size of the vehicle image and controlling vehicle image monitoring according to the vehicle image acquisition information; the reassembly vehicle image size has feature values; the feature values include vehicle model name, vehicle image monitoring time list identifier, park name, monitoring park area, vehicle integrity, and acquisition frequency.
[0069] Step A3: Execute control operations according to the control instructions to achieve vehicle image monitoring.
[0070] Step A4: Collect vehicle image monitoring images implemented by the vehicle database component, and send the vehicle image monitoring images to the vehicle feature model calculation component; the vehicle feature model calculation component is used to generate a collection document based on the vehicle image monitoring images and the vehicle image collection information, and to monitor the vehicle model in the vehicle image monitoring based on the collection document.
[0071] Step A4 is followed by obtaining the feature value from the collected document; and monitoring the vehicle model in the vehicle image monitoring based on the feature value.
[0072] Traditional vehicle model monitoring systems involve three steps: manual image acquisition, manual image uploading, and manual visual identification of vehicle models. This process is not only inefficient but also prone to errors due to visual blindness, significantly reducing the system's performance.
[0073] The vehicle model monitoring system and method provided by this invention adds feature values to the vehicle model, so that the vehicle model image appearing during the identification process will contain the feature values. As long as a photo of the vehicle model is captured at any moment during the identification process, the photo will contain the feature value information. After collecting the photo, the vehicle image monitoring component can quickly analyze all information related to vehicle model identification, such as the vehicle model name, monitoring location, gear lever, positive image, and scene, by parsing the feature values. Therefore, this method is far superior to existing vehicle model identification and monitoring systems in terms of both vehicle model monitoring efficiency and accuracy.
[0074] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple; relevant parts can be referred to the method section.
[0075] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
