[0052] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0053] In order to solve the problems existing in the prior art, the embodiments of the present disclosure provide an electronic fence monitoring method, system, device, storage medium and program product. Figure 1 A schematic diagram of the division scheme of the first electronic fence area and the second electronic fence area adopted in the present disclosure is shown, wherein the streets or road sections represented by blue lines are set as the first electronic fence area, that is, the area jointly enclosed by these blue lines is the first electronic fence area, and the area jointly enclosed by red lines, or the area between two red lines is set as the second electronic fence area. Figure 1 It includes elements such as "sidewalk", "lane", "traffic light", "barrier / dividing belt / lane line" to divide the electronic fence area, but Figure 1 This is just an example to illustrate the division rules of the first electronic fence area and the second electronic fence area. Figure 1 The shapes of the first electronic fence area and the second electronic fence area shown are regarded as limitations of the present disclosure.
[0054] The present disclosure first provides an electronic fence monitoring method, the process of which is as follows: Figure 2 As shown, the following steps are included:
[0055] Step S1:
[0056] The streets and road sections that need to be monitored are set as the first electronic fence area, and the real-time satellite positioning information and identity information of all vehicles and pedestrians entering the first electronic fence area are obtained.
[0057] All motor vehicles are equipped with satellite positioning devices, and traffic management departments can obtain the positioning information and vehicle registration information of motor vehicles according to their authority.
[0058] For pedestrians (including electric bicycles), the traffic management department can locate their mobile phones and obtain positioning information based on their authority, and can also obtain the real-name information of the mobile phone in accordance with the law.
[0059] The above positioning information is the latitude and longitude information. The positioning information set for entering the first electronic fence is D = {(x0i ,y 0i )|i>=1},x 0i Indicates longitude, y 0i The civil positioning accuracy of Beidou satellites has reached 0.1 meters, which can meet the requirements of accurate monitoring of traffic violations.
[0060] Assign each location information an identity label d i The identity tag corresponds to the vehicle registration information and mobile phone real-name information. That is, the mapping relationship between positioning information and identity information is established:
[0061] f:D→d i .
[0062] Step S2:
[0063] Based on the actual road traffic scene, the second electronic fence area is delineated.
[0064] The scope of the second electronic fence area is set according to the traffic restrictions of the actual road, for example: the isolation railings and isolation belts set on the actual road are used as one of the boundaries of the second electronic fence area, or the boundaries of the second electronic fence area are defined according to the traffic lights and road markings at the intersection.
[0065] Step S3:
[0066] According to the traffic rules and traffic time, determine the entrance of the second electronic fence area, and determine the longitude and latitude (x 0a ,y 0a )、(x 0b ,y 0b ). Among them, (x 0a ,y 0a ) represents the latitude and longitude of point A, (x 0b ,y 0b ) represents the latitude and longitude of point B.
[0067] Step S4:
[0068] According to the prohibited passage time, a coordinate function curve of each boundary of the second electronic fence area is established on the electronic map.
[0069] Specifically, the intersection of each border of the second electronic fence area is selected as the rectangular coordinate origin O (0, 0), and the coordinate function curve of each border of the second electronic fence area is established in the positive area of the coordinate system, wherein the origin O is the mapping of the longitude and latitude (x0, y0) of the intersection in the rectangular coordinate system, wherein any intersection can be used as the coordinate origin, and one section of the border is set in the positive area of the rectangular coordinate system, and each section of the border is monitored simultaneously and separately, which can reduce complex operations. Establishing the coordinate function curve of each border of the second electronic fence area in other areas of the coordinate system is a direct algorithm transformation of those skilled in the art based on the embodiments of the present disclosure, and should fall within the scope of the present disclosure.
[0070] Preferably, each boundary of the second electronic fence area can be respectively established in a newly established rectangular coordinate system to establish a coordinate function curve, and perform violation judgment separately.
[0071] Taking a straight line as an example, the coordinate function curve of a certain boundary of the second electronic fence area is:
[0072] y=mx, m≥0 is the slope of the straight line.
[0073] Step S5:
[0074] The positioning information set D = {(x 0i ,y 0i )|i>=1}, the longitude and latitude of both ends of the entrance of the second electronic fence area (x 0a ,y 0a ) and (x 0b ,y 0b ), mapped to the rectangular coordinate system, we get:
[0075] Positioning information coordinates (x i ,y i ), the latitude and longitude coordinates A(x a ,y a ) and B(x b ,y b ).
[0076] In the embodiment of the present disclosure, it is assumed that x a <x b ,y a <y b .
[0077] Step S6:
[0078] Determine the positioning information coordinates (x i ,y i ) is perpendicular to the projection coordinate of the coordinate axis x on the rectangular coordinate function curve (x i ,y i′), and the projection coordinates of the positioning information coordinates perpendicular to the coordinate axis y on the coordinate function curve (x i ′,y i ).like Figure 3 shown.
[0079] If the positioning information has no intersection with the coordinate function curve in the direction perpendicular to the coordinate axis x or the coordinate axis y, the projection coordinates of the positioning information in this direction are abandoned.
[0080] Step S7:
[0081] Violation judgment.
[0082] 1) For the projection coordinate (x i ,y i ′) or / and projection coordinates (x i ′,y i ), real-time calculation (y i ′-y i ) or / and (x i ′-x i ), “-” indicates subtraction.
[0083] (y i ′-y i ) or / and (x i ′-x i )A value of 0 or a negative value is considered a warning state.
[0084] This warning state indicates that the vehicle or pedestrian has crossed the boundary of the second electronic fence area at this time.
[0085] 2) Satisfy x a <x i <x b , or y a <y i <y b Under the condition of , that is, entering from the entrance of the second electronic fence area.
[0086] If the real-time traffic light signal in the forward direction is green, cancel the above (y i ′-y i ) or / and (x i ′-x i ) appears in the warning state of 0 value and negative value. If the real-time traffic light signal in the forward direction is red, it is judged as a violation.
[0087] 3) The above (y i ′-y i ) or / and (x i ′-x i ) When the warning state of 0 value and negative value appears, if x a >xi , or x i >x b , or y a >y i , or y i >y b conditions and is judged as a violation.
[0088] Step S8:
[0089] According to the violation judgment result, the camera near the boundary entrance of the second electronic fence area is called to record and capture the location information coordinates of the traffic violation.
[0090] Step S9:
[0091] According to the location information coordinates judged as violations and the tag information contained in the location information coordinates, the illegal vehicle or pedestrian is determined. Alternatively, for illegal snapshots with tag information of 0, the identity information of the corresponding person is further confirmed through portrait (face recognition).
[0092] As another feasible embodiment, in step S4, the coordinate function curves of each boundary of the second electronic fence area are fused with the time variable, and the time variable is used as a switch factor for judging traffic violations, so that real-time monitoring of traffic violations at traffic light intersections can be achieved, and the adjustment of the electronic fence area caused by changes in traffic light signals at complex intersections can be adapted. That is, the embodiment of the present disclosure can adjust the boundary of the second electronic fence area in real time according to the number and change rules of traffic lights. Among them, according to the adjustment of the electronic fence area of the intersection caused by the change of traffic light signals, the coordinate function curves of each boundary of the second electronic fence area are changed in real time in the electronic map.
[0093] Furthermore, in an embodiment of the present disclosure, all positioning information within the first electronic fence area is tracked simultaneously.
[0094] Based on the inspiration of the embodiments of the present disclosure, those skilled in the art can generate coordinate function curves for the complete boundaries of the second electronic fence area in the rectangular coordinate system established in the electronic map, and implement traffic violation judgment for each boundary section according to the calculation method for judging traffic violations recorded in the embodiments.
[0095] For ease of implementation, no other boundary entrances of the electronic fence are set except for the actual intersections for the actual road isolation railings, isolation belts, lane lines, etc. The "lane line" in this application is a solid line, a double yellow line, or a custom boundary that should not be crossed or climbed over.
[0096] As another embodiment, the second electronic fence area of the present disclosure does not have a boundary entrance and can be used as an anti-intrusion monitoring system.
[0097] The embodiment of the present disclosure combines satellite positioning data with electronic fences, uses a simple algorithm to monitor illegal crossing of lines, climbing over and other behaviors in real time, and can promptly call the nearest camera to the illegal location to clearly record and capture the illegal behavior; and uses data fusion technology to use identity information as label data of positioning information, so as to quickly confirm the identity of the violator. The implementation scheme of the present disclosure has simple operation steps and low implementation costs.
