Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In an embodiment of the present invention, as shown in fig. 1, an advertisement partition delivery method is disclosed, an execution subject of the method is a cloud server, and specifically, the method includes the following steps:
step S101: one or more advertisement delivery areas are constructed in advance, and each advertisement delivery area corresponds to one or more advertisement area tasks.
Specifically, a user (i.e., an advertiser or an administrator, etc.) may use a terminal device to label on an electronic map by using a standard region selection frame, after the labeling is completed, the terminal device of the user uploads the positions and labeling sequences of a plurality of labeled region selection frames to a cloud server, and the cloud server constructs an advertisement delivery region in the electronic map according to the positions and labeling sequences of the plurality of region selection frames. Each area selection frame can be expressed as a unit coordinate, and after being marked on the electronic map, each area selection frame can be connected according to the marked sequence to form a closed advertisement delivery area. When there are a plurality of advertisement placement areas, the plurality of advertisement placement areas may be numbered for easy distinction, and a uniquely determined area ID may be assigned to each advertisement placement area when the division is performed. The advertisement placement area may be a province, a city, an area of a city, etc. One or more advertisement area tasks corresponding to each advertisement delivery area are also set by the user according to the characteristics of each advertisement delivery area in advance by using the terminal equipment. Further, the advertisement area task comprises one or more advertisements; an advertisement delivery instruction; and an advertisement delivery area. More specifically, the advertisements comprise advertisement IDs and advertisement release contents, each advertisement corresponds to a unique determined advertisement ID so as to be convenient for distinguishing a plurality of advertisements, the advertisement release contents can be pictures, videos, characters and the like, and a user can edit the advertisement release contents in advance and directly upload the advertisement release contents when setting regional tasks; the advertisement putting instruction comprises the contents of advertisement playing time length, advertisement playing sequence or advertisement playing priority and the like. Further, the above-mentioned advertisement, advertisement placement instruction, and advertisement placement area mentioned in the advertisement area task may exist in the form of a schedule table.
Step S102: and judging whether the construction of each advertisement delivery area is legal or not according to a preset advertisement delivery area legality judgment strategy, if so, executing the step S103, and otherwise, executing the step S106.
Specifically, in this embodiment, it is determined whether the construction of each advertisement delivery area is legal, that is, whether there is an error in the construction of each advertisement delivery area, because in this embodiment, the construction of the advertisement delivery area is constructed according to the positions and labeling order of the plurality of area selection boxes labeled by the user, the validity of the construction mentioned in this embodiment refers to whether the connection order of the area selection boxes is incorrect during construction. As shown in fig. 3 and 4, fig. 3 shows legal advertisement delivery areas, wherein A, B, C, D, E is an area selection box and the connection sequence is A, B, C, D, E, A. Fig. 4 shows an illegal advertising region, which is connected in A, D, C, B, E, A order. That is, the connection sequence is inconsistent with the labeling sequence set by the user, so that the constructed advertisement delivery area is inconsistent with the advertisement delivery area that the user wants to construct, and subsequently, the actual advertisement delivery area is inconsistent with the advertisement delivery area that the user wants to deliver when advertisement delivery is performed.
Step S103: and acquiring a vehicle GPS coordinate, determining whether the vehicle is in the advertisement delivery area according to a preset vehicle position determination strategy and the vehicle GPS coordinate, if so, executing a step S104, otherwise, executing a step S105.
Step S104: determining a first advertisement delivery area where the vehicle is located currently, generating a first schedule according to one or more area tasks corresponding to the first advertisement delivery area, and controlling an LED control device to deliver advertisements corresponding to the first schedule to an LED display screen on the vehicle for display according to the first schedule.
Since there may be one or more pre-constructed advertisement delivery areas, when there are 1 pre-constructed advertisement delivery area, the advertisement delivery area is used as the first advertisement delivery area. Under the condition that a plurality of advertisement putting areas are constructed in advance, if the vehicle is judged to be simultaneously located in 2 or more than 2 advertisement putting areas according to the vehicle GPS coordinates of the vehicle and the position coordinates of the plurality of advertisement putting areas constructed in advance, namely the vehicle is located at the junction of the 2 or more than 2 advertisement putting areas, one of the 2 or more than 2 advertisement putting areas where the vehicle is located needs to be determined as the advertisement putting area (namely, the first advertisement putting area) where the vehicle is finally located.
Further, after a first advertisement delivery area where the vehicle is located is determined, a first schedule is generated according to one or more area tasks corresponding to the first advertisement delivery area. In the following, taking as an example that there are a plurality of regional tasks corresponding to the first advertisement delivery region and each regional task includes a plurality of advertisements, a detailed process is described: each regional task corresponds to an execution priority, and the execution priority can be set when a user sets the regional task by using the terminal equipment or determined according to the time when the user sets the regional task. Each regional task includes a plurality of advertisements, each advertisement corresponds to a placement priority, and the placement priority of each advertisement may be set when the user sets the regional task using the terminal device, or may be determined according to the advertisement fee corresponding to each advertisement, for example, the higher the advertisement fee is, the higher the placement priority is, the earlier the placement is performed when the advertisement is placed. The preset permutation and combination rule is as follows: determining the execution sequence of a plurality of regional tasks according to the execution priority, determining the delivery sequence of a plurality of advertisements corresponding to each regional task according to the delivery priority, sequencing the advertisements in the regional tasks according to the execution sequence and the delivery sequence, and generating a first schedule. In the first schedule, in addition to the advertisement delivery content, an advertisement playing instruction is also included, and the advertisement playing instruction includes the playing sequence, the playing time length, the brightness of the LED display screen during playing, and the like of each advertisement.
Furthermore, the user can change the regional task corresponding to the first advertisement delivery region at any time through the terminal device, after the regional task of the first advertisement delivery region is changed by the user and uploaded to the cloud server, the cloud server can regenerate the first schedule according to the changed regional task and send the first schedule to the LED control device, and then the LED control device controls the LED display screen to play the advertisement according to the new first schedule.
Step S105: and finishing the advertisement putting.
Step S106: and reconstructing an illegal advertisement delivery area according to a preset advertisement delivery area reconstruction strategy, and executing the step S102.
In this embodiment, before a GPS coordinate of a vehicle is acquired and an advertisement delivery area where the vehicle is located is determined according to the GPS coordinate of the vehicle, it is determined whether construction of each advertisement delivery area is legal according to a preset advertisement delivery area validity determination policy, and when the construction is illegal, the illegal advertisement delivery areas are reconstructed, and until each advertisement delivery area is legal, a subsequent advertisement delivery step is performed, so that it is avoided that accuracy of subsequent advertisement delivery is affected when the constructed advertisement delivery areas are illegal.
In another embodiment of the present invention, assuming that M advertisement delivery areas are constructed in total, as shown in fig. 2, i is made to take values of 1,2,3, and … … M in sequence for a flowchart of the i-th advertisement delivery area validity determination method, so that whether the construction of each advertisement delivery area is legal or not can be determined according to a preset advertisement delivery area validity determination policy.
Specifically, the method for judging the validity of the ith advertisement delivery area comprises the following steps:
step S201: and presetting a coordinate system, acquiring the endpoint coordinates of each edge in the ith advertisement delivery area, and determining a plurality of groups of two intersected edges and the intersection point position of each group of two intersected edges in the ith advertisement delivery area according to the endpoint coordinates of each edge in the ith advertisement delivery area.
In this embodiment, the predetermined coordinate system is a predetermined coordinate system on a plane where the advertisement delivery area is located. In actual determination, two edges in the ith advertisement placement area may be arbitrarily selected to determine whether the two edges intersect, and taking two edges 1 and 2 in the ith advertisement placement area as an example, the coordinates of two endpoints in the edge 1 are P1(x1, y1) and P2(x2, y2), and the coordinates of two vertices in the edge 2 are Q1(x3, y3) and Q2(x4, y 4). If the edge 1 and the edge 2 are crossed, the following steps are required:
calculating a vector formed by connecting P1 and Q1 and a vector formed by connecting P1 and Q2, performing vector cross-product calculation on the vector formed by connecting P1 and Q1 and an edge 1 vector (namely the vector formed by connecting P1 and P2) to obtain a calculation result value crosssp 1, and performing vector cross-product calculation on the vector formed by connecting P1 and Q2 and the edge 1 vector (namely the vector formed by connecting P1 and P2) to obtain a calculation result value crosssp 2.
Calculating a vector formed by connecting Q1 and P1 and a vector formed by connecting Q1 and P2, performing vector cross-product calculation on the vector formed by connecting Q1 and P1 and an edge 2 vector (namely the vector formed by connecting Q1 and Q2) to obtain a calculation result value crosssp 3, and performing vector cross-product calculation on the vector formed by connecting Q1 and P2 and the edge 2 vector (namely the vector formed by connecting Q1 and Q2) to obtain a calculation result value crosssp 4.
crossp1＝＝＝＝>(Q1-P1)x(P2-P1)
crossp2＝＝＝＝>(Q2-P1)x(P2-P1)
crossp3＝＝＝＝>(P1-Q1)x(Q2-Q1)
crossp4＝＝＝＝>(P2-Q1)x(Q2-Q1)
If crosssp 1 crosssp 2<0 and crosssp 3 crosssp 4<0 (i.e., crosssp 1 is opposite to crosssp 2 and crosssp 3 is opposite to crosssp 4), then it can be determined that edge 1 intersects edge 2.
Step S202: and judging whether one or more groups of two intersected edges exist, wherein the positions of two end points of at least one edge are respectively arranged at two sides of the intersection point position, if so, executing the step S203, and if not, executing the step S204.
Step S203: and judging that the ith advertisement delivery area is not constructed legally.
Step S204: and judging that the construction of the ith advertisement delivery area is legal.
If errors occur during the construction of the advertisement delivery areas, the connection sequence of the selection frames of the areas is inconsistent with the labeling sequence. As shown in fig. 3, in the case that the connection order is consistent with the labeling order, the vertices (each vertex pair is a region selection box, which may be regarded as a point) in the advertisement delivery area are sequentially connected end to end, if the edges intersect with each other, the positions of the two endpoints of any one edge are on the same side of the intersection position (the endpoints and the intersection are considered to be on the same side when the endpoints and the intersection coincide with each other), and a specific identification manner may be to establish a computer coordinate system in the advertisement delivery area, determine whether the coordinates of the endpoints and the intersection on the computer coordinate system are the same, and determine whether the intersection and the endpoint have a coincidence relationship. As shown in fig. 4, when the connection order does not match the labeling order, the connection of the vertices in the advertisement delivery area is not sequentially connected first in order, and the AD edge and the BE edge intersect with each other, but the AD edge is on both sides of the intersection and the BE edge is also on both sides of the intersection. . Therefore, in this embodiment, as long as it is determined that one or more groups of two intersecting edges exist in one advertisement delivery area, and the two end points of at least one edge are located at two sides of the intersection point, the advertisement delivery area can be determined to be illegal, and the connection order is inconsistent with the labeling order. Thereby determining that the construction of the advertisement delivery area is illegal.
In another embodiment of the present invention, reconstructing an illegal advertisement delivery area according to a preset advertisement delivery area reconstruction policy includes obtaining positions and a labeling order of a plurality of area selection frames corresponding to the illegal advertisement delivery area, sequentially connecting the area selection frames according to the labeling order, and connecting the area selection frame at the last position of the labeling order with the labeling selection frame at the first position of the labeling order to generate a reconstructed advertisement delivery area.
In another embodiment of the present invention, whether a vehicle is in an advertisement delivery area is determined according to a preset vehicle position determination strategy and a vehicle GPS coordinate, and whether the vehicle is in one or more advertisement delivery areas may be determined one by one according to the vehicle GPS coordinate and the position coordinate of each advertisement delivery area.
As shown in fig. 5, preferably, the determining whether the vehicle is in the advertisement delivery area according to the preset vehicle position determination strategy and the vehicle GPS coordinates includes the following steps:
step S301: and converting the GPS coordinates of the vehicle and the advertisement delivery area into coordinate points under the same plane, and making a ray in any direction by taking the coordinate points as starting points.
As shown in fig. 6, understandably, the earth is regarded as a sphere with a radius r of 1, the equator is an xy plane, the projection of the greenwich mean line on the xy plane is regarded as a y axis, the Z axis is the rotation axis of the earth passing through the south pole and the north pole, the GPS data is expressed in terms of latitude and longitude, the latitude and longitude (θ, Φ) is a vector with a mode of 1 with coordinates (x, y, Z), and the vector is converted into a point a (θ 1, Φ 1) with spatial coordinates x ═ rsin θ cos Φ, y ═ rcos Φ, Z ═ rsin, and the point a (θ 1, Φ 1) with the latitude and longitude can be projected onto the equator plane (xy plane) to form a coordinate point a (x1, y1) under the plane. In the invention, the GPS coordinate of the vehicle is represented by longitude latitude, and the advertisement delivery area is also represented by precision latitude, so that the GPS coordinate of the vehicle and the advertisement delivery area can be converted into coordinate points under the same plane by the method, thereby facilitating the subsequent judgment. Specifically, when the advertisement placement region is converted, only the coordinates of each vertex of the advertisement placement region may be converted in order to reduce the amount of calculation.
Step S302: and calculating the number of intersections of the ray and each advertisement putting area.
Step S303: and judging whether the number of the intersection points of one advertisement delivery area and the ray is an odd number, if so, executing the step S304, otherwise, executing the step S305.
In this embodiment, when the number of intersections between the ray and the advertisement placement area is determined, the coordinate points are located at the vertices of the polygonal area and at each side of the advertisement placement area, and at this time, the number of intersections can be recorded as 1, and the vehicle is considered to be within the advertisement placement area. In addition, if the ray emitted from the starting point just coincides with the edge of the advertisement putting area, the number of the intersection points can be recorded as 2, and therefore the vehicle is determined to be outside the advertisement putting area.
Step S304: it is determined that the vehicle is within the advertisement delivery area.
Step S305: it is determined that the vehicle is not within the advertisement delivery area.
In this embodiment, by determining whether the number of intersections of a ray with the vehicle coordinates as a starting point and each advertisement delivery area is an odd number, if the number of intersections of at least one advertisement delivery area and the ray in a plurality of advertisement delivery areas constructed in advance is an odd number, it is verified that the vehicle is within the advertisement delivery area.
