Fig. 1 is the schematic flow diagram of the road safety hazard investigation method provided by an embodiment of the present application, with reference to Fig. 1, the detailed description of the road safety hazard investigation method is as follows:

In S101, image information and location information of the target road to be checked are acquired.

In some embodiments, S101 can be completed through the following steps:

S1010, through the high-definition panoramic camera equipped with a global positioning system inside, collect the image information and GPS information of each collection point on the target inspection road. Location.

Specifically, a plurality of high-definition panoramic cameras equipped with a Global Positioning System (Global Positioning System, GPS) can be installed on the work vehicle that performs the collection task. Angled road image.

Exemplarily, the shooting angles of the high-definition panoramic camera can be set to the front, the front left and the front right at an angle of 45° to the front. For another example, the shooting angles of the high-definition panoramic camera can be set to be the front, the left direction perpendicular to the front, and the right direction respectively. Also for example, when the traveling direction of the work vehicle is due east, the shooting directions of the camera installed on the top of the vehicle are respectively 60 degrees to the southeast, 60 degrees to the due east and 60 degrees to the northeast. The shooting directions above can be adjusted according to actual road conditions. The collection of road images from multiple angles can comprehensively provide the actual road conditions, surrounding facilities and surrounding environment of the target inspection road, facilitate the selection of the best inspection angle, and accurately locate road safety hazards.

The above-mentioned image information includes but is not limited to video format and picture format. Whenever the high-definition panoramic camera captures and saves image information, the GPS information, shooting direction information and image information of the above-mentioned high-definition panoramic camera are stored in association at the same time, that is, when the computer program calls the image information information, the GPS information and shooting direction information corresponding to the image information can be extracted or displayed at the same time.

S1011, collecting the GPS information of the highway mileposts on the edge of the road to be checked, and correspondingly recording the marking information on the highway mileage poles.

Highway mileage piles refer to a group of stone steles set up in equal length order from the starting point to the end point on the road route, marking the mileage and numbering of rural and urban suburban roads. Used to calculate the length of a road segment and mark the position along a certain point on the road.

The mileage of commonly used highways is mostly 100-meter piles or kilometer piles. One hundred-meter piles are set every 100 meters, and one-thousand-meter piles are set every 1,000 meters. In actual scenarios, the highway mileage piles next to the road may be missing or damaged, which may lead to the inability to determine the specific location of the hidden danger location, or to accurately describe and record the hidden danger location during the investigation of road safety hazards. Therefore, it is necessary to collect the GPS information of the highway mileage pile and the marking information on the corresponding highway mileage pile at the same time, which can be provided to the computer for calculation and processing, and used to determine the detailed position of each collection point on the target investigation road section.

The marking information on the road mileage post includes the number of the road where the road section is located and the mileage of the road mileage post from the starting point of the road; for example, the marking information on the road mileage post can be "GXXX 50", that is, the road mileage post where the road mileage post is located The location is 50 kilometers away from the starting point of the XXX national highway; for example, the marking information on the road milepost may only include the mileage.

S1012, according to the GPS information of the road mileage pile, the marking information on the road mileage pile and the GPS information of the collection point, generate the electronic pile number of the collection point, the electronic pile number includes the marking information of the road mileage pile with the smallest mileage adjacent to the collection point , and the distance from the collection point to the highway mileage pile with the smallest mileage.

According to the GPS information of the road mileage piles and the marking information on the road mileage piles, and then according to the GPS information of each collection point between every two road mileage piles, through the GPS dynamic positioning and ranging algorithm, the two adjacent adjacent roads on the target are checked. Each collection point on the road section between road mileage piles is calibrated electronically, and then obtains the electronic pile numbers of all collection points on the target investigation road; The number is the index system of the road coordinate axis.

Based on the above-mentioned electronic stakes, the image information, road data or other relevant information of each collection point can be associated with the electronic stakes of each collection point, and a road information management system indexed by the electronic stakes can be established to realize coordinate position and Combination of road information.

Exemplarily, Fig. 2 is a schematic diagram of a road mileage pile provided by an embodiment of the present application, which includes three continuous highway mileage piles: kilometer pile 20, kilometer pile 21, and kilometer pile 22; The road section 210 between the meter pile 20 and the kilometer pile 21 , the road section 220 between the kilometer pile 21 and the kilometer pile 22 ; point A is located on the road section 210 . The mark information on the kilometer pile 20 is "X K7", that is, the kilometer pile 20 is set up on the road numbered X, and the distance between the kilometer pile 20 and the starting point of the X road is 7 kilometers; The meter pile 21 and the kilometer pile 22 are not described in detail. Wherein, the distance between point A and kilometer pile 20 is n meters, then the electronic stake number of point A can be expressed as "X K7+n meters".

S1013: Generate location information of collection points according to the road number, road direction and electronic stake number.

If only the mileage is recorded on the highway mileage pile in the target investigation road, manually enter the road number of the target investigation road, integrate the road number, the road direction in the shooting perspective, and the electronic stake number of each collection point to generate each collection The location information of the point is stored in association with the image information of the corresponding collection point.

If the highway mileage stakes in the target investigation road contain road number information and mileage, the road direction in the shooting perspective and the electronic stake number of each collection point are directly integrated to generate the location information of each collection point.

Exemplarily, in the image information of a collection point B, the road direction is from county P to county Q, and the electronic stake number of the collection point is "X2 K15+260 meters", then the location information of collection point B can be recorded as "X2-P county-Q county direction (K15+260 meters)".

The above-mentioned embodiments can provide accurate and comprehensive road section location information for road safety hidden danger investigation work, and can provide specific angle picture information to quickly locate specific hidden danger locations, greatly improving the work efficiency of road safety management departments.

In S102, according to preset hidden danger scene parameters and image information of the target road to be checked, determine hidden danger scenes on the target road to be checked, where there are one or more hidden danger scenes.

Specifically, it can identify and analyze the road type in the collected image information and the road type parameters of the corresponding road type, and screen and locate the road type, road type parameters and preset hidden danger scene parameters in the image information of the targeted road The goal is to check the hidden danger scenes on the road.

Wherein, the road type may include one or more of curves, ramps, intersections, bridges, and tunnels, and the road type parameters may include the position of the curve, the turning radius of the curve, the turning angle of the curve, the curve length of the ramp, location of the ramp, slope value of the ramp, height difference of the ramp, length of the ramp, location of the intersection, width of the intersection, location of the bridge, length of the bridge, location of the tunnel, and length of the tunnel one or more of.

In some embodiments, according to the road data of the historical traffic accident road section and the road data of the special road type in the relevant standards, the hidden danger scene parameters are preset. For example, road sections with a turning radius less than 300 meters and a turning angle greater than 60 degrees can be defined as sharp curve road sections, road sections with a slope greater than 6% and length greater than 100 meters can be defined as steep slope road sections, and intersections with a width of less than 15 meters can be defined as small entrances ; The above three examples can all be used as judgment parameters for a single hidden danger scenario. Through image processing and image recognition and other technologies, analyze the actual road parameters in the collected image information, and match and screen the actual road parameters with the preset hidden danger scene parameters. If there are no parameters of one or more single hidden danger scenes, then the collection point is judged as a hidden danger scene.

In the actual screening process of hidden danger scenarios, firstly, a single hidden danger scenario can be screened out, and secondly, combined hidden danger scenarios can be screened out. Exemplarily, a road section is both on a curve and on a ramp. Although the turning radius and turning angle of the curve do not meet the parameters of a single hidden danger scene, when it is combined with a ramp with a certain slope, it will constitute a traffic Hidden danger scene, this scene is a combined hidden danger scene.

For the above-mentioned single hidden danger scenarios, it includes but not limited to sharp bend road sections, steep slope road sections, level intersection sections, small access sections, bridge sections, tunnel sections, roadside dangerous sections, cross-section sudden change sections and other typical road safety hidden danger single scenarios. The above combined hidden danger scenarios include but are not limited to typical road safety hidden danger combination scenarios such as curved and slope combined road sections, road sections passing through villages and towns, intersection and curved slope combined road sections, bridge tunnel and curved slope combined road sections.

The above-mentioned embodiments can efficiently perform preliminary screening on the target roads to be checked, and preferentially screen out locations that are prone to non-compliance with road regulations, thereby reducing the complicated steps of item-by-item hidden trouble screening for all images of the entire road section.

In S103, in response to the screening instruction, the road safety hidden danger screening is performed on the hidden danger scene according to the preset screening items.

In some embodiments, S103 may be implemented through the following steps:

S1311. Establish a corresponding relationship between hidden danger scenarios and preset screening items, where the preset screening items include one or more of traffic sign markings, road design indicators, isolation protection measures, and other road state information.

Exemplarily, the long slope road section is a hidden danger scene where large truck accidents occur frequently, and for the hidden danger scene of the long slope road section, the investigation items that have screening significance for it are preset in a targeted manner. Fig. 3 is a schematic diagram of the preset investigation items of the long slope section provided by an embodiment of the present application. As shown in Fig. 3, six inspection items are set for the scene of the long slope section, including traffic signs, traffic markings, traffic sight distance, Physical indicators, isolation protection and others. Among them, the six major inspection items are further classified into 11 sub-items in total, namely: traffic signs including steep slope warning signs and speed limit value settings, traffic markings including marking status and center line settings, traffic sight distance, physical Metrics include ramp length and slope values, isolation protection includes guardrail settings, and other items include pavement condition, roadside clearance, and custom content. In addition, FIG. 3 also includes preset inspection conclusions corresponding to each inspection item, which are used to describe the inspection conclusion clearly and concisely.

S1312. Responding to the investigation instruction, perform investigation of road safety hidden dangers in hidden danger scenes according to preset investigation items, and obtain investigation conclusions corresponding to each preset investigation item.

The checking instruction may include a single checking instruction issued by the technician by clicking a certain checking item, or an checking instruction of all items sent by the technician by clicking the mouse, or a checking instruction automatically issued by a computer program.

When the response technician clicks on an inspection item to issue an inspection command, the current hidden danger scene is checked based on the inspection item, and the inspection conclusion of the inspection item is obtained; the response technician clicks on the inspection conclusion corresponding to the inspection item to send Instructions, the display interface of the terminal can display the technical requirements and guidance information of relevant national standards or industry standards for the inspection project, and technicians can manually judge the inspection results by reading these reference information.

Exemplarily, FIG. 4 is a schematic diagram of a process of troubleshooting road safety hazards provided by an embodiment of the present application.

Suddenly appearing and causing accidents. Crossing markings are generally along the main line and buried 20cm away from the outer edge of the curb stone. If there is no curb stone, it should be buried 20cm away from the inner edge of the soil road shoulder and should not be buried on the roadbed slope.

It should be noted that the content of the standard guidelines displayed in the above-mentioned standard guide area can be retrieved and displayed from the preset standard guide library according to the click instruction of the technician; the preset standard guide library can include various national standards or industry standards; all the regulations in the standard guide library can be classified and classified according to the various situations that may exist in each inspection item, so that it can be flexibly retrieved and displayed directly according to the instructions during the inspection process.

Specifically, for different hidden danger scenarios, carry out item-by-item investigation according to the corresponding preset inspection items. During the screening process, the preliminary screening conclusions are obtained according to the judgment basis and criteria of the corresponding preset screening items. The judgment basis may include image information of different shooting angles of the hidden danger scene, image information of other collection points near the hidden danger scene at a specific distance, or may include image information of different angles of other collection points near the hidden danger scene. The set standard guides the standard in the library.

Preferably, the image information of the above-mentioned different shooting angles may be the image information of the best viewing angle.

Exemplarily, to check the crossing mark in a hidden danger scene with a crossing, first locate the starting point of the crossing in the hidden danger scene, obtain the image information of the right angle of view of the position, and automatically judge the right angle of view through an intelligent algorithm Whether there is a crossing mark in the image information of the crossing mark, and select the check box corresponding to the judgment result in the investigation conclusion option corresponding to the crossing mark. For example, if the crossing lacks a crossing mark, select the "Missing" check box in the investigation conclusion corresponding to the "crossing mark" check item. In some embodiments, a prompt window may also pop up on the display interface of the terminal at the same time, prompting that "this position lacks a crossing mark". Further, after completing the judgment of the intersection mark, other investigation items related to the intersection can also be checked, such as the intersection sign. At this time, the image information of the frontal perspective at a position 90 meters away from the starting point of the intersection can be obtained and displayed, and the image can be judged Whether there is an intersection sign in the information, the judgment result is the same as the above-mentioned steps, and will not be repeated here.

In the above-mentioned embodiment, according to the unique characteristics of different types of hidden danger scenarios and related standards and specifications, targeted inspection items are set, and the preset inspection items can be added, deleted or modified according to regional characteristics and specific task requirements, which can be flexible and efficient Realize the investigation of road safety hazards.

In one scenario, if there are omissions or errors in the preliminary investigation conclusion, the conclusion of manual judgment input by the user in the text input area may be received, and the text input area is located on the display interface of the terminal.
