Description

Technical Field

[0001] This invention belongs to the field of intelligent transportation technology, specifically relating to a mobile non-motorized vehicle capture device and its deployment method. Background Technology

[0002] Currently, my country has a large number of non-motorized vehicles, especially electric bicycles, which have reached more than 400 million. The number of traffic accidents caused by non-motorized vehicle traffic violations is increasing year by year, putting enormous pressure on urban road traffic.

[0003] To facilitate the management of non-motorized vehicle traffic violations, existing technologies often use mobile devices instead of fixed enforcement cameras. By mounting the cameras on tripods or other lightweight mobile containers, the equipment can be easily moved to intersections where more violations require enforcement. However, whether installing cameras on traffic enforcement poles or using mobile devices, both require professional engineers to be on-site to debug and set parameters, preventing automated deployment and significantly increasing operation and maintenance costs.

[0004] Therefore, how to provide an effective solution to facilitate the deployment of non-motorized vehicle capture equipment has become an urgent problem to be solved in the existing technology. Summary of the Invention

[0010] If a target sample environment image that matches the current environment image exists in the sample library, then the initialization setting parameters of the mobile non-motorized vehicle capture device deployed at the intersection corresponding to the target sample environment image are obtained.

[0011] The setting parameters of the video acquisition unit and the radio frequency acquisition unit are adjusted based on the initialization setting parameters so that vehicle violation detection can be performed through the video acquisition unit and the radio frequency acquisition unit after the setting parameters of the video acquisition unit and the radio frequency acquisition unit are adjusted.

[0012] Based on the above disclosure, this invention acquires the current environmental image through a video acquisition unit after power-on and performs similarity matching between the current environmental image and sample environmental images in a sample library. The sample library stores sample environmental images of multiple intersections. If a target sample environmental image matching the current environmental image exists in the sample library, the initialization settings parameters for the mobile non-motorized vehicle capture device at the intersection corresponding to the target sample environmental image are obtained. Based on these initialization settings parameters, the setting parameters of the video acquisition unit and the radio frequency acquisition unit are adjusted. Thus, during the deployment of the mobile non-motorized vehicle capture device, image matching can determine the current deployment intersection, and the initialization settings parameters of the current deployment intersection are automatically used to adjust the setting parameters of the video acquisition unit and the radio frequency acquisition unit. This completes the debugging of the non-motorized vehicle capture device without requiring a professional engineer to be present to debug the setting parameters, achieving automatic deployment of the mobile non-motorized vehicle capture device.

[0023] The capture area of ​​the video acquisition unit is adjusted based on the line drawing parameters in the initialization settings.

[0024] The pitch angles of the video acquisition unit and the radio frequency acquisition unit are adjusted based on the pitch angle parameter in the initialization settings.

[0025] In one possible design, if a target sample environment image matching the current environment image exists in the sample library, then the initialization setting parameters for the mobile non-motorized vehicle capture device deployed at the intersection corresponding to the target sample environment image are obtained, including:

[0026] If a target sample environment image with a similarity exceeding a preset similarity threshold exists in the sample library, it is determined that a target sample environment image matching the current environment image exists in the sample library, and the initialization setting parameters of the mobile non-motorized vehicle capture device deployed at the intersection corresponding to the target sample environment image are obtained.

[0027] In one possible design, the method further includes:

[0042] To facilitate the deployment of non-motorized vehicle capture devices, this application provides a mobile non-motorized vehicle capture device and its deployment method, which can realize the automatic deployment of the mobile non-motorized vehicle capture device.

[0043] The deployment method for mobile non-motorized vehicle capture equipment provided in this application embodiment can be applied to the main control unit of the mobile non-motorized vehicle capture equipment. The mobile non-motorized vehicle capture equipment includes the main control unit, video acquisition unit, and radio frequency acquisition unit. The main control unit is communicatively connected to the video acquisition unit and the radio frequency acquisition unit to perform data interaction or communication.

[0044] The deployment method of the mobile non-motorized vehicle capture device provided in the embodiments of this application will be described in detail below.

[0045] like Figure 1 As shown, the first aspect of this application provides a method for deploying a mobile non-motorized vehicle capture device, which may include, but is not limited to, the following steps S101-S104.

[0046] Step S101. After power-on, acquire the current environment image through the video acquisition unit.

[0047] In this embodiment, during the deployment of the mobile non-motorized vehicle capture device, the device can first be moved to the intersection where it needs to be deployed, and then activated. At this time, the main control unit can send a control signal to the video acquisition unit to control the video acquisition unit to acquire images of the current environment. The video acquisition unit can be an existing license plate capture camera.

[0048] In one or more embodiments, the mobile non-motorized vehicle capture device further includes a central control unit (CCU). The CCU can be used for self-testing and status management of the device. After power-on, the CCU can perform a self-test and send the self-test results to the main control unit. During the deployment of the mobile non-motorized vehicle capture device, after powering on and receiving self-test feedback information from the CCU indicating successful self-testing, the main control unit can send a control signal to the video acquisition unit to enable the video acquisition unit to acquire the current environmental image.

[0049] Step S102. Perform similarity matching between the current environment image and the sample environment images in the sample library.

[0050] The sample library contains environmental images of multiple intersections.

[0051] Specifically, users can pre-acquire environmental images of multiple intersections where mobile non-motorized vehicle capture devices have been previously deployed via the video acquisition unit, record the initialization settings of the non-motorized vehicle capture devices deployed at each intersection, and then bind the environmental images of each intersection with the initialization settings of the mobile non-motorized vehicle capture devices at the intersections and store them in a sample library. The initialization settings of the non-motorized vehicle capture devices can refer to the initialization settings of the video acquisition unit and the radio frequency acquisition unit of the non-motorized vehicle capture devices.

[0052] After acquiring the current environment image through the video acquisition unit, the main control unit performs similarity matching between the current environment image and each sample environment image in the sample library.

[0053] Step S103. If a target sample environment image that matches the current environment image exists in the sample library, then obtain the initialization setting parameters of the mobile non-motorized vehicle capture device deployment at the intersection corresponding to the target sample environment image.

[0054] Specifically, if there is a target sample environment image in the sample library that has a similarity to the current environment image that exceeds a preset similarity threshold, then it is determined that there is a target sample environment image in the sample library that matches the current environment image, and the main control unit obtains the initialization setting parameters of the mobile non-motorized vehicle capture device at the intersection corresponding to the target sample environment image from the sample library.

[0055] The preset similarity threshold can be set according to the actual situation, such as 80%, 85%, or 90%.

[0056] The initialization settings parameters may include, but are not limited to, focal length parameters, line drawing parameters, and / or pitch angle parameters. Line drawing parameters may be used to delineate the detection area for traffic violations.

[0057] Understandably, if there is no target sample environment image in the sample library that matches the current environment image, the main control unit can generate a prompt message to remind the user to manually set the initial setting parameters of the mobile non-motorized vehicle capture device at the current intersection.

[0058] Step S104. Adjust the setting parameters of the video acquisition unit and the radio frequency acquisition unit based on the initialization setting parameters so that after the setting parameters of the video acquisition unit and the radio frequency acquisition unit are adjusted, vehicle violation detection can be performed through the video acquisition unit and the radio frequency acquisition unit.

[0059] In this embodiment of the application, adjusting the setting parameters of the video acquisition unit and the radio frequency acquisition unit based on the initialization setting parameters can be achieved by adjusting the focal length of the video acquisition unit based on the focal length parameter in the initialization setting parameters, adjusting the capture area of ​​the video acquisition unit based on the line drawing parameter in the initialization setting parameters, and adjusting the pitch angle of the video acquisition unit and the radio frequency acquisition unit based on the pitch angle parameter in the initialization setting parameters.

[0060] In one or more embodiments, after the setting parameters of the video acquisition unit and the radio frequency acquisition unit are adjusted, a feedback signal indicating that the setting parameter adjustment is complete can be sent to the main control unit. At this time, the main control unit can send a ready status notification to the video acquisition unit and the radio frequency acquisition unit so that the radio frequency acquisition unit can obtain license plate information within its detection range and the video acquisition unit can obtain vehicle capture images within its field of view.

[0061] In one or more embodiments, the radio frequency acquisition unit can send the license plate information it acquires to the main control unit, and the video acquisition unit can send the vehicle capture images it acquires to the main control unit. The main control unit can perform spatiotemporal fusion of the license plate information acquired by the radio frequency acquisition unit and the vehicle capture images acquired by the video acquisition unit, and then send them to the data center so that the data center can perform vehicle violation detection based on the spatiotemporally fused license plate information and vehicle capture images.

[0062] By using spatiotemporal fusion, the license plate information obtained by the radio frequency acquisition unit can be associated with the vehicle capture images obtained by the video acquisition unit to form a complete chain of evidence, which can be used for subsequent detection and management of non-motorized vehicle traffic violations.

[0063] In one or more embodiments, the mobile non-motorized vehicle capture device may be equipped with a wireless communication unit. After spatiotemporally fusing the license plate information obtained by the radio frequency acquisition unit with the vehicle capture image obtained by the video acquisition unit, the spatiotemporally fused license plate information and vehicle capture image can be sent to the data center through the wireless communication unit.

[0064] The mobile non-motorized vehicle capture device deployment method provided by this invention acquires the current environmental image through a video acquisition unit after power-on and performs similarity matching between the current environmental image and sample environmental images in a sample library. The sample library stores sample environmental images of multiple intersections. If a target sample environmental image matching the current environmental image exists in the sample library, the initialization setting parameters for the mobile non-motorized vehicle capture device deployment at the intersection corresponding to the target sample environmental image are obtained. Based on the initialization setting parameters, the setting parameters of the video acquisition unit and the radio frequency acquisition unit are adjusted. Thus, during the deployment of the mobile non-motorized vehicle capture device, the intersection where the mobile non-motorized vehicle capture device is currently deployed can be determined through image matching, and the initialization setting parameters of the currently deployed intersection can be obtained to automatically adjust the setting parameters of the video acquisition unit and the radio frequency acquisition unit, thereby completing the debugging of the non-motorized vehicle capture device. This eliminates the need for professional engineers to be present to debug the setting parameters, achieving automatic deployment of the mobile non-motorized vehicle capture device. This saves equipment debugging costs and greatly improves equipment debugging efficiency, facilitating practical application and promotion. Secondly, using mobile non-motorized vehicle monitoring equipment eliminates the need for re-casting, pole erection, and wiring, thus avoiding conflicts with existing urban planning. Furthermore, mobile monitoring equipment allows for easy relocation to intersections requiring traffic management, reducing relocation costs.

[0066] The video acquisition unit is used to acquire the current environmental image after the device is powered on and started.

[0067] The main control unit is used to perform similarity matching between the current environment image and sample environment images in the sample library, wherein the sample library stores sample environment images of multiple intersections.

[0068] The main control unit is also used to obtain the initialization setting parameters of the intersection corresponding to the target sample environment image and the deployment of the mobile non-motorized vehicle capture device if there is a target sample environment image in the sample library that matches the current environment image;

[0069] The main control unit is also used to adjust the setting parameters of the video acquisition unit and the radio frequency acquisition unit based on the initialization setting parameters, so that after the setting parameters of the video acquisition unit and the radio frequency acquisition unit are adjusted, vehicle violation detection can be performed through the video acquisition unit and the radio frequency acquisition unit.

[0070] In one possible design, the mobile non-motorized vehicle capture device also includes a central control unit. Specifically, when the video acquisition unit is used to acquire images of the current environment after power-on, it is used for:

[0071] After powering on and receiving self-test feedback information indicating successful self-test from the central control unit, a control signal is sent to the video acquisition unit to enable the video acquisition unit to acquire the current environmental image.
