[0002] With the rapid development of modern transportation networks, highways, as the main arteries connecting cities, carry enormous amounts of traffic and logistics. Furthermore, with the continuous improvement of the highway network and the rapid growth of vehicle ownership, the safe operation and incident handling of highways have become important issues that need to be addressed in the field of traffic management. Traffic accidents, vehicle breakdowns, and other incidents are inevitable during highway operations. These incidents often lead to traffic congestion, delays, and even more serious safety incidents. Therefore, quickly and accurately locating highway incidents and visually displaying relevant information to management personnel is crucial for improving highway operational efficiency and safety.

[0003] To address these challenges, existing highway management systems have introduced a range of technologies to monitor and locate highway incidents. However, these technologies still have some shortcomings in practical application. Existing event displays, mostly in text or table format, lack intuitiveness and visibility. They cannot clearly reflect the relative location and specific lanes of the incident on the highway, making it difficult for managers to quickly and accurately understand the impact of the incident, hindering highway management efficiency. Summary of the Invention

[0046] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] Figure 1This is a flow chart of a method for locating and displaying an event on a highway provided by an embodiment of the present invention. Figure 1 The execution entity may be a highway-based event location display system. The highway-based event location display method provided in embodiments of the present invention is executed by a computer device. Accordingly, the highway-based event location display system runs on the computer device. The order of the steps in this flowchart may be changed, and some steps may be omitted, depending on different needs.

[0049] like Figure 1 As shown, the method includes the following steps.

[0050] S1, draw a plan view of the target area, where each lane on the highway is shown in the plan view.

[0051] Figure 2 It is a schematic diagram of the plan display of the target area, which shows each lane on the highway. In addition, for the convenience of intuitive viewing, the plan display also shows the marking points on the highway in the target area, including toll stations, service areas, parking areas, transportation hubs, etc.

[0052] S2, when an alarm message is received, the corresponding camera is triggered according to the alarm message to collect images of the incident scene.

[0053] In this embodiment, the received alarm information includes the geographic location of the incident. Multiple cameras are placed at intervals along the highway. When an alarm is received, the corresponding camera is controlled to take a photo of the scene. Image processing is performed to obtain the lane where the incident occurred, and then the lane is marked on the display map. The specific steps include the following.

[0054] S2.1, pre-store the camera's identification and geographic coordinates.

[0055] S2.2, upon receiving an alarm message, parsing the event geographic coordinates in the alarm message.

[0056] S2.3, according to the geographic coordinates of the event and the geographic coordinates of the camera, find the camera closest to the event location.

[0057] S2.4, triggering the searched camera to capture images of the event scene.

[0058] S3, receiving the transmitted event scene images.

[0059] S4, performing image processing on the incident scene image to obtain the lane where the incident occurred.

[0060] The purpose of this step is to process the image to obtain the lane where the event is located. In an optional implementation, the following steps are specifically included.

[0061] S4.1, use Gaussian filter to denoise the event scene image.

[0062] S4.2, performing a histogram equalization operation to process the event scene image into a grayscale image.

[0063] S4.3, perform ROI selection operation to crop the image containing the road portion.

[0064] S4.4, use edge detection algorithm to extract edge information of the image to identify the position and shape of the lane line.

[0065] S4.5, use Hough transform to find straight line features corresponding to lane lines, cluster the multiple detected straight lines, and use the least squares method to fit the lane lines based on the clustering results.

[0066] S4.6, based on the relative positions of the lane lines in the image, determine the lane where the event is located by comparing the previous and next frame images.

[0067] First, the image is denoised and grayscale processed. The region of interest is then cropped. Lane lines are detected and fitted using edge detection algorithms and clustering. The lane where the incident occurred is determined based on the relative positions of lanes and a comparison of the previous and next frames. It is understood that the vehicle at the incident site is generally stationary, and its appearance in the previous and next frames remains unchanged. Therefore, the incident location can be determined based on the comparison of the previous and next frames.

[0068] S5, marking an event icon on the target lane on the target area plane display map based on the camera position and the lane where the event is located.

[0069] The purpose of this step is to mark the event on the target lane in the display image. The target lane refers to the lane where the event occurred. The specific steps include the following.

[0070] S5.1, pre-configure the horizontal coordinates of each camera in the plane display image of the target area.

[0071] S5.2, pre-configure the longitudinal coordinates of each lane in the target area plan display.

[0072] S5.3, the horizontal coordinate of the corresponding camera is used as the horizontal coordinate of the event icon, and the vertical coordinate of the lane where the located event is located is used as the vertical coordinate of the event icon.

[0073] S5.4. Mark the target lane on the target area plan display according to the horizontal coordinate and vertical coordinate of the event icon.

[0074] To improve identification efficiency, this embodiment uses the camera's horizontal coordinates and the lane's vertical coordinates in the display image to identify events. The coordinates of each camera and lane are pre-stored. When the camera closest to the event is found, its horizontal coordinates are retrieved as the horizontal coordinates for the event identification. After image processing determines the lane where the event is located, the vertical coordinates of the target lane are retrieved as the vertical coordinates for the event identification. The event is then identified on the display image based on these horizontal and vertical coordinates.

[0075] This embodiment can mark the relative position and specific lane of the event in the display diagram, so that management personnel can intuitively know the location of the event and the scope of impact, thereby improving the management efficiency of the highway.
