Description

Technical Field

[0001] The present invention relates to an advertising monitoring device, in particular to an outdoor advertising monitoring device. Background Art

[0002] For the monitoring of outdoor billboards, especially for the advertising signs on both sides of the road, in the prior art, most of them adopt the methods of shooting and positioning to obtain the content of the billboards. However, in the conventional shooting method, due to the uncertain speed of the vehicle, the shooting angle is uncertain, so the perspectives of the content of the obtained billboards are different. And the specific positioning of the billboard is not accurate enough, especially the size of the billboard cannot be specifically and accurately obtained. When facing customers, the corresponding parameters and advertising effects cannot be fully provided. Summary of the Invention

[0003] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide an outdoor advertising monitoring device.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] An outdoor advertising monitoring device includes a rangefinder that follows the vehicle. The rangefinder is used to measure the distances from the two side edges of the billboard. The control device obtains the length L and the set inclination angle a of the billboard by combining the two sets of distances measured at any interval time with the distance traveled by the vehicle during this time period.

[0006] The obtaining method is specifically as follows:

[0007] Step (1): Assume the time T. When T = T0, the distances from the two side edges of the billboard are L1 and L2 respectively; when the time T =

[0008] T1, the distances from the two side edges of the billboard are L3 and L4 respectively; during the time period from T0 to T1, the vehicle travels a distance of P0.

[0009] According to the following formula:

[0010] D1 2 + (P1 + P0) 2 = L1 2 (Formula 1)

[0011] D1 2 + P1 2 = L3 2 (Formula 2)

[0012] D2 2 + (P2 + P0) 2 = L2 2 (Formula 3)

[0013] D2 2 + P22 = L4 2 (Equation 4)

[0014] According to (Equation 1) and (Equation 2), D1 and P1 are obtained. According to Equation (3) and Equation (4), D2 and P2 are obtained;

[0015] Wherein, D1 and D2 are respectively the distances between the two side edges of the billboard perpendicular to the road, and P1 and P2 are respectively the distances between the vehicle and the vertical point at time T1;

[0016] Step (2): Obtain the length L of the billboard according to the following formula

[0017] L 2 = (D1 - D2) 2 + (P2 - P1) 2 (Equation 5).

[0018] The above control device obtains the setting inclination angle a of the billboard according to the following formula,

[0019] Sin a = (P2 - P1) / L (Equation 6).

[0020] The above P0 is obtained according to the following formula:

[0021] P0 = (T1 - T0)V 平均 (Equation 7)

[0022] Wherein, V 平均 is the average vehicle speed during the time period from T0 to T1.

[0023] The above vehicle is equipped with a GPS locator, and the control device obtains the coordinate position of the billboard according to the feedback of the GPS locator.

[0024] Furthermore, the obtaining of the coordinate position of the above billboard is specifically:

[0025] When the time is T1, assuming that the vehicle position is the origin, the deviation direction of the billboard is the positive direction of the X-axis and the positive direction of the Y-axis, and the positioning coordinates of the GPS locator are (X, Y),

[0026] Then, the coordinate position of the billboard is (X + (D1 + D2) / 2, Y + (P1 + P2) / 2).

[0027] The above vehicle is equipped with a photographing device, and the control device obtains the content of the billboard according to the feedback of the photographing device.

[0028] Furthermore, the control device obtains that the content of the billboard when L1 = L2 in the feedback of the photographing device is the front content.

[0029] Further, based on the feedback from the rangefinder: L1 = L2, the above control device triggers the photographing device to obtain the front content of the billboard.

[0030] Further, the above control device identifies the image and / or text of the billboard content fed back by the photographing device through an image recognition module and stores it as the key information of the billboard.

[0031] Further, the format of the above time T includes year, month, day, hour, minute, and second, and the control device obtains the content of the billboard corresponding to the time T.

[0032] The beneficial effects of the present invention are as follows:

[0033] For the outdoor advertising monitoring device of the present invention, through two groups of spacing data obtained by the rangefinder and combined with the driving distance of the vehicle within a time period, the length and the set inclination angle of the billboard can be obtained, which is convenient, simple, and accurate. Combined with the positioning of the vehicle, the accurate coordinates of the billboard can also be obtained. Combined with the photographing device, through the calibration of the spacing, the display content on the front of the billboard can be accurately obtained.

[0034] The outdoor advertising monitoring device of the present invention has a simple structure, is easy to use, obtains accurate data, can automatically record billboard parameters, addresses, current advertising information, etc., and accurately and effectively provides relevant billboard information for the demand side, and has strong practicability and wide applicability.

[0039] As Figure 1 shown, the vehicle travels along the road. The control device obtains the length L and the set inclination angle a of the billboard by measuring two groups of distances at any interval time (from T0 to T1) and combining the distance P0 traveled by the vehicle during this time period;

[0040] The method is specifically as follows:

[0041] Step (1):

[0045] D1 2 + P1 2 = L3 2 (Equation 2)

[0046] D2 2 +(P2 + P0) 2 = L2 2 (Equation 3)

[0049] In the formula, D1 and D2 are the distances from the two sides of the billboard perpendicular to the road respectively, P1 and P2 are the distances between the vehicle and the vertical point at time T1 respectively; P0 is obtained according to the following formula:

[0050] P0 = (T1 - T0)V 平均 (Equation 7)

[0051] In the formula, V 平均 is the average vehicle speed within the time period from T0 to T1.

[0052] Step (2):

[0053] (A), Obtain the length L of the billboard according to the following formula, L 2 = (D1 - D2) 2 +(P2 - P1) 2 (Equation 5);

[0054] (B), Obtain the setting inclination angle a of the billboard according to the following formula,

[0055] Sina = (P2 - P1) / L (Equation 6).

[0056] (C) Obtaining the coordinate position of the billboard, specifically:

[0057] When the time is T1, assuming the vehicle position as the origin, the bias of the billboard as the positive directions of the X-axis and Y-axis, and the positioning coordinates feedback by the GPS locator are (X, Y),

[0058] then, the coordinate position of the billboard (column) is (X + (D1 + D2) / 2, Y + (P1 + P2) / 2).

[0059] (D) Obtaining the content of the billboard, specifically:

[0060] Method 1: The shooting device obtains the display content of the billboard in real time with time T, and different times display the display content of the billboard at different angles.

[0061] Obtaining the front content: The control device obtains the time T3 when this condition holds according to the feedback of the rangefinder L1 = L2, and then takes the display content of the billboard corresponding to the time T3 as the front content of the advertisement and stores the record.

[0062] Method 2: The control device triggers the shooting device to obtain the front content of the billboard according to the feedback of the rangefinder: L1 = L2, and stores the triggered time T3 as the time point for obtaining this front content.

[0063] (E) When recording, the control device can also identify the image and / or text of the billboard content feedback by the shooting device through the image recognition module, and store it as the key information of the billboard for subsequent review.

[0064] Embodiment

[0065] When the time is T0, it is measured that L1 = 9.4 meters and L2 = 10.7 meters;

[0066] When the time is T1, it is measured that L3 = 5.6 meters and L4 = 5.3 meters;

[0067] During the period from T0 to T1, the vehicle travels P0 = 5.6 meters;

[0068] Through the above formula, it can be obtained that: D1 = 4.3 meters, D2 = 1.5 meters, P1 = 2.1 meters, P2 = 4.8 meters;

[0069] Furthermore, it can be obtained that

[0070] The length L of the billboard is 3.9 meters, and the inclination angle a is approximately 45 degrees.
