Description

Technical Field

[0001] The invention belongs to the technical field of poster placement, and in particular relates to an intelligent management system for market placement of poster frames. Background Art

[0002] In today's era of information explosion, visual marketing has become one of the indispensable means of brand communication and market promotion. Posters, as a traditional and effective visual medium, not only carry key information about brand image, product information and promotional activities, but also serve as an important bridge connecting brands and consumers' emotions. However, with the increasing complexity of the market environment and the diversification of consumer needs, the traditional poster frame placement and management methods face many challenges such as low efficiency, high cost, and missing data. In order to meet these challenges, improve the efficiency and effectiveness of poster placement, and meet the brand's needs for precision marketing, cost control and data-driven decision-making, the poster frame market placement intelligent management system came into being.

[0003] There are also some solutions related to poster placement in the prior art. For example, the invention patent application of a method and system for placing and correcting public transportation advertisements based on a large model and machine vision with publication number CN118333696A detects the age of passengers and obtains the detection results of the age of passengers by using an RBF neural network-decision-level fusion algorithm optimized by an adaptive sparrow search algorithm, and then detects the height of passengers by using a BP neural network algorithm optimized by a longhorn beard algorithm, and obtains the detection results of the height of passengers. It realizes the automatic generation of posters based on passenger characteristics and product information by using large model technology, and verifies the effect of posters in real time by the degree of attention. It has been proven that although it effectively improves the poster quality and update feedback efficiency, its applicable scenarios are limited to the public transportation environment and cannot be applied to the conventional poster placement scenario. The existing poster placement technology usually carries out the placement of various pre-placed posters according to the manually set poster placement time period and placement duration for the conventional poster placement scenario. Its limitations are: on the one hand, the manually set placement time period may not accurately cover the active time period of the target audience, making the pre-placed posters unable to effectively reach the target group, reducing the targeting and effectiveness of the placement; on the other hand, the same placement mode is repeated every day, lacking novelty and variety, which makes the audience prone to visual fatigue and advertising immunity.

[0004] In addition, the existing poster delivery process lacks intelligent control of the display brightness of the poster delivery, and only relies on the brightness of the external environment for basic adjustment, while ignoring the in-depth analysis of the relationship between the color of the poster content and the appropriate viewing display brightness. This may cause overexposure of colors and loss of details in strong light environments, or dim colors in low light environments that are difficult to recognize, thus affecting the audience's viewing experience.

The related information includes theme type, content image, cumulative release time requirement, cumulative release attention requirement and release budget requirement.

[0009] The placement strategy planning module is used to analyze the crowd density characteristics within the preset period of the target poster frame, and to plan the placement strategy for each pre-placed poster within the preset period of the target poster frame, so as to carry out the poster placement work within the preset period of the target poster frame.

[0010] The delivery benefit evaluation module is used to determine whether the delivery benefit of each pre-delivered poster meets the expected target in the middle of the poster delivery work of the preset period of the target poster frame, and mark the pre-delivered posters that do not meet the expected target as posters to be optimized.

[0011] The delivery strategy correction module is used to correct the delivery strategy of each poster to be optimized and re-execute it accordingly in the later stage of the poster delivery work of the preset period of the target poster frame.

[0012] The delivery brightness control module is used to adjust the poster delivery display brightness of the target poster frame in real time during the poster delivery work of the preset period of the target poster frame.

[0013] The cloud database is used to store the arrangement priority of each theme type of the target poster frame poster placement specification, store the upper and lower limits of the net traffic range corresponding to the unit off-peak period, store the placement costs per unit time during the peak, off-peak and low-peak periods of the target poster frame poster placement specification, and store the appropriate display brightness range corresponding to the color performance level of each subject.

Under the condition that the budget is controllable, the delivery range of each pre-delivery poster covers the complete working time of the target poster frame in a single day, thereby avoiding the waste of resources caused by excessive concentrated delivery, and ensuring that appropriate poster content is presented to the audience in different time periods.

[0016] (3) The present invention combines the external environment brightness and the main color performance level of the content image of the pre-posted poster to adjust the poster display brightness of the target poster frame in real time, thereby avoiding overexposure or dimming of colors, making the poster colors more vivid and the details clearer, and ensuring that the poster content can maintain the best visual effect under different lighting conditions, thereby enhancing the audience's visual experience.

[0021] Reference Figure 1 As shown, the present invention provides a poster frame market placement intelligent management system, including: a poster information uploading module, a placement strategy planning module, a placement benefit evaluation module, a placement strategy correction module, a placement brightness control module and a cloud database.

[0022] The poster information uploading module is connected to the delivery strategy planning module, the delivery strategy planning module is respectively connected to the delivery benefit evaluation module and the delivery brightness control module, the delivery benefit evaluation module is connected to the delivery strategy correction module, and the cloud database is respectively connected to the delivery strategy planning module, the delivery strategy correction module, and the delivery brightness control module.

[0023] The poster information uploading module is used to upload each pre-released poster and related information within a preset period to the target poster frame storage unit, and the related information includes theme type, content image, cumulative release time requirement, cumulative release attention requirement and release budget requirement.

[0024] The placement strategy planning module is used to analyze the crowd density characteristics within the preset period of the target poster frame, and to plan the placement strategy for each pre-placed poster within the preset period of the target poster frame, so as to carry out the poster placement work within the preset period of the target poster frame.

[0025] Specifically, the analysis of the crowd density characteristics within the preset period of the target poster frame includes: obtaining the start date and end date of the preset period, collecting the entrance and exit crowd flow at each unit time point on each day from the same start date to the same end date in each historical year of the geographical place where the target poster frame is located, substituting them into a rectangular coordinate system with time as the horizontal axis and crowd flow as the vertical axis, and drawing and obtaining the exit crowd flow change curve and its fitting function for each day within the preset period of each historical year of the geographical place where the target poster frame is located , entrance flow change curve and its fitting function ,in is the number of each historical year, , is the number of each day in the preset cycle, .

[0026] It should be noted that the above and Specifically, the exit flow change curve and the entrance flow change curve of each day in a preset period of each historical year of the geographical location where the drawn target poster frame is located can be imported into Matlab software, and obtained using the best fitting tool of Matlab software.

[0027] The unit time periods of a single day are numbered and marked in chronological order, and the starting time point and ending time point of each unit time period of a single day are represented as , is the number of each unit time period, .

[0028] Using the formula Analyze the net flow of people in each unit time period of each day in each historical year preset period at the geographical location where the target poster frame is located, among which is the preset unit duration, according to the formula Further obtain the reference net flow of people in each unit time period of a single day within a preset period of the geographical location where the target poster frame is located, where is the number of historical years, The preset cycle days.

[0029] According to the upper and lower limits of the net passenger flow interval corresponding to the unit off-peak period stored in the cloud database, the peak period sequence, off-peak period sequence and low-peak period sequence of the passenger flow in a single day within the preset period of the geographical location where the target poster frame is located are planned, and this is used as the passenger flow density feature within the preset period of the target poster frame.

[0030] It should be noted that the specific planning process of the peak time period sequence, off-peak time period sequence and low-peak time period sequence of the daily passenger flow within the preset period of the geographical place where the above-mentioned target poster frame is located is as follows: mark each unit time period within the preset period of the geographical place where the target poster frame is located in which the single-day reference net passenger flow is greater than the upper limit value of the net passenger flow interval corresponding to the unit off-peak time period as each peak time period, forming the peak time period sequence of the daily passenger flow within the preset period of the geographical place where the target poster frame is located; mark each unit time period within the preset period of the geographical place where the target poster frame is located in which the single-day reference net passenger flow is less than the lower limit value of the net passenger flow interval corresponding to the unit off-peak time period as each low-peak time period, forming the low-peak time period sequence of the daily passenger flow within the preset period of the geographical place where the target poster frame is located; mark each unit time period within the preset period of the geographical place where the target poster frame is located in which the single-day reference net passenger flow is within the net passenger flow interval corresponding to the unit off-peak time period as each off-peak time period, forming the low-peak time period sequence of the daily passenger flow within the preset period of the geographical place where the target poster frame is located.

[0031] Reference Figure 2 As shown, specifically, the planning of placement strategies for each pre-placed poster within a preset period of the target poster frame includes: S1. arranging positions of the pre-placed posters in a carousel sequence to generate a fixed carousel sequence within the preset period of the target poster frame.

[0032] S2. Set the number of rotations of the fixed rotation sequence on a single day within a preset period and the fixed duration of a single rotation.

[0033] S3. Plan the single delivery duration of each pre-delivery poster for the peak time sequence, the off-peak time sequence, and the low-peak time sequence within the preset period of the target poster frame.

[0034] S4. Place all pre-placed posters in a preset period of the target poster frame in a carousel format.

[0035] It should be noted that when setting the number of carousel times and the fixed duration of a single carousel sequence within the preset period, the product of the number of carousel times and the fixed duration of a single carousel is required to be equal to the preset poster delivery working duration of the target poster frame for a single day.

[0036] Specifically, the arranging the positions of the pre-placement posters in a carousel sequence includes: extracting the theme type of each pre-placement poster, and determining whether there are pairs of pre-placement posters with the same theme type.

[0037] If it is judged that it does not exist, the arrangement priority of each theme type of the target poster frame poster delivery specification stored in the cloud database is used to obtain the arrangement priority of each pre-delivered poster theme type and arrange the carousel sequence position of each pre-delivered poster in order of arrangement priority from high to low.

[0038] If it is judged that they exist, then the pre-placement poster pairs of the same theme type are screened, and the pre-placement poster pair with the highest arrangement priority is used as the first and last positions of the fixed carousel sequence, and the pre-placement poster pair with the second highest arrangement priority is used as the second first and last positions of the fixed carousel sequence, and so on to form a first-order subsequence of the fixed carousel sequence. The remaining pre-placement posters that do not have the same theme type are arranged in order of arrangement priority from high to low to form a second-order subsequence of the fixed carousel sequence and inserted into the middle of the first-order subsequence to achieve the carousel sequence position arrangement of each pre-placement poster.

[0039] It should be noted that the theme types of the above-mentioned pre-release posters include but are not limited to corporate recruitment, promotional activities, public welfare publicity, education and training, sports events, etc.

[0040] The embodiment of the present invention arranges the pre-placed posters in a carousel sequence by alternating themes of the pre-placed posters, thereby breaking the monotony of traditional single-theme poster placement, and can continuously attract the audience's attention, thereby maximizing the use of limited resources and improving the pertinence and effectiveness of poster placement.

[0041] Specifically, the planning target poster frame within the preset period of each pre-release poster for the peak time sequence, the flat time sequence, and the low-peak time sequence, including: extracting the cumulative release time requirement, the cumulative release attention requirement, and the release budget requirement of each pre-release poster, and performing a ratio analysis with the preset cycle days to obtain the average daily release time of each pre-release poster , average daily attention and average daily budget ,in is the number of each pre-released poster, .

[0042] The total number of people flow corresponding to the peak time sequence, the flat time sequence and the low peak time sequence of a single day in the preset period of the geographical place where the target poster frame is located is counted, and the ratio of the total number of people flow to the preset reference number of people flow is used to obtain the corresponding placement attention of the peak time sequence, the flat time sequence and the low peak time sequence of a single day in the preset period of the geographical place where the target poster frame is located, which are recorded as .

[0043] Extract the target poster frame stored in the cloud database and the corresponding placement costs per unit time during the peak, flat and off-peak periods of the poster placement specifications, which are recorded as .

[0044] Equation system The analysis is performed to obtain the delivery duration of each pre-delivered poster for the peak time sequence, the flat time sequence, and the low-peak time sequence within the preset period of the target poster frame, that is, ,in They are respectively the corresponding durations of the peak time sequence, the off-peak time sequence and the low-peak time sequence of a single day within the preset period of the geographical location where the target poster frame is located.

[0045] It should be noted that if the above If there is no solution, Automatically set to the unit delivery duration, i.e. 1min.

[0046] Then the computational model Get the single delivery duration of each pre-delivered poster for the peak time sequence within the preset period of the target poster frame, where express , express , It is the fixed duration of a single carousel of a fixed carousel sequence on a single day within the preset period. It should be noted that the above calculation model obtains the single delivery duration of each pre-delivery poster for the peak time sequence within the preset period of the target poster frame in minutes. Similarly, the single delivery duration of each pre-delivery poster for the off-peak time sequence and the low-peak time sequence within the preset period of the target poster frame is obtained by the same method.

[0047] Exemplarily, the following is a process for solving the delivery duration of a pre-delivery poster for peak time sequence, off-peak time sequence, and low-peak time sequence within a preset period of a target poster frame: a pre-delivery poster is recorded as a reference example poster, if the average daily delivery duration of the pre-delivery poster is 12 hours, the average daily delivery attention is 66, and the average daily delivery budget is 79 yuan, the corresponding delivery costs per unit time in the peak, off-peak, and low-peak time periods of the target poster frame poster delivery specification are 8 yuan / hour, 7 yuan / hour, and 5 yuan / hour respectively, the corresponding delivery attentions for the peak time sequence, off-peak time sequence, and low-peak time sequence of a single day within the preset period of the geographical location where the target poster frame is located are 80, 50, and 30 respectively, and the corresponding durations for the peak time sequence, off-peak time sequence, and low-peak time sequence of a single day within the preset period of the geographical location where the target poster frame is located are 5 hours, 10 hours, and 9 hours respectively, then the equation group for solving the delivery duration of the pre-delivery poster for the peak time sequence, off-peak time sequence, and low-peak time sequence within the preset period of the target poster frame is: , and we can solve .

[0048] Furthermore, the calculation process of the single delivery time length of the pre-delivered poster for the peak time sequence within the preset period of the target poster frame is as follows: the fixed single carousel time length of the fixed carousel sequence of a single day within the preset period is set to 0.5 hours, , which is greater than 1, 6 minutes is directly used as the single delivery duration of the pre-delivery poster for the peak period sequence.

[0049] The embodiment of the present invention plans the single delivery duration of each pre-delivery poster in a preset period of the target poster frame for the peak time sequence, the off-peak time sequence, and the low-peak time sequence, and delivers each pre-delivery poster in the preset period of the target poster frame in a carousel form. Under the condition that the budget is controllable, the delivery range of each pre-delivery poster covers the complete working time of the target poster frame in a single day, thereby avoiding the waste of resources caused by excessive concentrated delivery, and ensuring that suitable poster content is presented to the audience in different time periods.

[0050] The placement benefit evaluation module is used to determine whether the placement benefit of each pre-placement poster meets the expected target in the middle of the poster placement work of the preset period of the target poster frame, and mark each pre-placement poster that does not meet the expected target as a placement poster to be optimized.

[0051] It should be noted that the mid-term of the poster placement work of the preset period of the above-mentioned target poster frame refers to the median date between the start date and the end date of the preset period.

[0052] Specifically, the judgment conditions for whether the delivery efficiency of the pre-delivery posters meets the expected goals include: the delivery cost, delivery duration and delivery attention of the pre-delivery posters are all within the reasonable expected mid-term range of the poster delivery work in the preset period of the corresponding target poster frame.

[0053] The delivery strategy correction module is used to correct the delivery strategy of each poster to be optimized and re-execute it accordingly in the later stage of the poster delivery work of the preset period of the target poster frame.

[0054] It should be noted that the later stage of the poster placement work in the preset period of the above-mentioned target poster frame specifically refers to the period between the median date and the end date within the preset period.

[0055] Specifically, the delivery strategy modification of each poster to be optimized includes: calculating the delivery time to be completed in the later stage of the poster delivery work of the preset period of the target poster frame for each poster to be optimized , To be completed delivery attention and remaining delivery budget ,in is the number of each poster to be optimized. .

[0056] It should be noted that the above It is obtained by subtracting the cumulative delivery time requirement of each poster to be optimized from the corresponding delivery time in the middle of the poster delivery work of the preset period of the target poster frame. and .

[0057] Equation system The analysis is performed to obtain the poster delivery work of the preset period of the target poster frame. The delivery time of each poster to be optimized for the peak time sequence, the flat time sequence, and the low peak time sequence is carried out in the later stage, that is, .

[0058] The calculation method for the single delivery duration of each pre-delivered poster for the peak time sequence within the preset period of the target poster frame is the same. The single delivery duration of each poster to be optimized for the peak time sequence, off-peak time sequence, and low-peak time sequence is calculated in the later stage of the poster delivery work of the preset period of the target poster frame.

[0059] The placement brightness control module is used to control the poster placement display brightness of the target poster frame in real time during the poster placement work of the preset period of the target poster frame.

[0060] Specifically, the real-time control of the poster display brightness of the target poster frame includes: sensing the current external environment brightness of the target poster frame through an ambient light sensor arranged in the target poster frame.

[0061] Extract the content image of the poster currently placed in the target poster frame, evaluate the main color performance level of the poster currently placed in the target poster frame, obtain the main color performance level of the poster currently placed in the target poster frame according to the appropriate display brightness range corresponding to each main color performance level stored in the cloud database, calculate the contrast between each appropriate display brightness in the range and the current external environment brightness of the target poster frame, and select the appropriate display brightness corresponding to the maximum contrast as the current poster display brightness of the target poster frame, so as to adjust the poster display brightness of the target poster frame in real time.

[0062] Specifically, the evaluation of the main color expression level of the poster currently placed in the target poster frame includes: converting the content image of the poster currently placed in the target poster frame into the HSV color space, obtaining the hue, saturation and brightness of each pixel in the content image, dividing each hue interval according to a predefined principle, extracting the top three hue intervals in terms of the number of pixels and calculating their color expression, combining the preset expression weights corresponding to the top three hue intervals in terms of the number of pixels, analyzing the main color expression of the poster currently placed in the target poster frame and taking the integer divisor of it and the preset benchmark main color expression as the main color expression level of the poster currently placed in the target poster frame.

[0063] It should be noted that the above-mentioned predefined principle refers to dividing the 360-degree color wheel according to preset degrees to obtain various hue intervals.

[0064] The color expression calculation process of each hue interval ranked in the top three in terms of the number of pixels is as follows: extract the saturation and brightness of each pixel in each hue interval ranked in the top three in terms of the number of pixels, calculate their ratios to the reference saturation and reference brightness respectively, obtain the saturation ratio and brightness ratio of each pixel in each hue interval ranked in the top three in terms of the number of pixels, multiply the saturation ratio and brightness ratio of each pixel and then add them up to obtain the color expression of each hue interval ranked in the top three in terms of the number of pixels.

[0065] Specifically, the contrast ratio between each suitable display brightness in the interval and the current external environment brightness of the target poster frame is the absolute deviation brightness ratio between each suitable display brightness in the interval and the current external environment brightness of the target poster frame.

[0066] It should be noted that the absolute deviation brightness ratio of each suitable display brightness in the above-mentioned interval and the current external environment brightness of the target poster frame is obtained by subtracting the absolute values ​​of each suitable display brightness in the interval from the current external environment brightness of the target poster frame, and taking the ratio of the absolute value difference result to the current external environment brightness of the target poster frame as the absolute deviation brightness ratio of each suitable display brightness in the interval and the current external environment brightness of the target poster frame.

[0067] The embodiment of the present invention combines the external environment brightness and the main color performance level of the content image of the pre-placed poster to perform real-time adjustment on the poster placement display brightness of the target poster frame, thereby avoiding overexposure or dimming of colors, making the poster colors more vivid and the details clearer, and ensuring that the poster content can maintain the best visual effect under different lighting conditions, thereby enhancing the audience's visual experience.

[0068] The cloud database is used to store the arrangement priority of each theme type of the target poster frame poster placement specification, store the upper and lower limits of the net traffic range corresponding to the unit off-peak period, store the placement costs corresponding to the unit time length in the peak, off-peak and low-peak periods of the target poster frame poster placement specification, and store the appropriate display brightness range corresponding to each subject color performance level.
