Summary of the invention

[0004] To this end, the present invention provides a multimedia display system for scientific and technological information, so as to overcome the problem in the prior art that the display content of scientific and technological information is not coordinated according to the interaction of users, thus affecting the display efficiency of scientific and technological information.

[0005] To achieve the above object, the present invention provides a multimedia display system for scientific and technological information, comprising:

[0006] A storage unit, which is used to store a number of scientific and technological information, each of which is provided with a corresponding label;

[0007] An extraction unit, connected to the storage unit, for selecting corresponding scientific and technological information from the storage unit;

[0008] An output unit connected to the extraction unit for displaying the scientific and technological information transmitted by the extraction unit;

[0009] A collection unit, which is arranged on the side wall of the output unit and is used to collect video information of the crowd around the output unit;

[0010] The analysis unit is connected to the storage unit, the extraction unit and the acquisition unit respectively, and uses the group video information to determine the dwell time of the portrait feature, and determines the attention feature rating based on the ratio of the dwell time of the portrait feature to the display time of the corresponding scientific and technological information based on the person. The attention feature rating includes primary features and secondary features. The information level of a single scientific and technological information is divided based on the number of primary features, or the ratio of the number of primary features to secondary features. The information level includes primary information, secondary information and tertiary information. Based on the statistical proportion of each information level, it is determined whether the exhibition layout of the scientific and technological information by the extraction unit is qualified, and when it is determined that the exhibition layout of the scientific and technological information by the extraction unit is unqualified, the exhibition time of the secondary information is replaced based on the matching degree of the secondary information and the tertiary information, or the exhibition frequency of the corresponding tertiary information is determined based on the similarity between the secondary information and the tertiary information.

[0011] Furthermore, the acquisition unit acquires portrait video information in front of the output unit and transmits the portrait video information to the analysis unit, the analysis unit extracts and locks portrait features from the video information, and records in turn the length of time that each portrait feature stays within the acquisition range of the acquisition unit during the display of the scientific and technological information, and for a single portrait feature, calculates the ratio of the length of time the portrait feature stays to the length of time the scientific and technological information is displayed; if the length ratio is higher than a preset length ratio, the single portrait feature is recorded as a primary feature; if the ratio is less than or equal to the preset length ratio, the single portrait feature is recorded as a secondary feature.

[0012] Furthermore, the analysis unit divides the information level of a single scientific and technological information based on the number of primary features, including:

[0013] If the number of first-level features is greater than the second preset number, the information level of the single scientific and technological information is determined to be first-level information;

[0014] If the number of primary features is less than or equal to the second preset number and greater than the first preset number, the information level of the single scientific and technological information is divided based on the ratio of the number of primary features to the number of secondary features corresponding to the single scientific and technological information;

[0015] If the number of the first-level features is less than or equal to the first preset number, the information level of the single scientific and technological information is determined as third-level information.

[0016] Furthermore, the analysis unit divides the information level of the single scientific and technological information based on the quantity ratio of the primary feature to the secondary feature corresponding to the single scientific and technological information, including:

[0017] If the quantity ratio is less than or equal to the preset quantity ratio, the information level of the single scientific and technological information is classified as secondary information;

[0018] If the quantity ratio is greater than the preset quantity ratio, the information level of the single scientific and technological information will be divided into three levels of information.

[0019] Furthermore, the analysis unit is used to determine whether the display layout of the scientific and technological information by the extraction unit is qualified based on the statistical proportion of each information level, including:

[0020] If the proportion of primary information is the highest, then the extraction unit is judged to have qualified display layout for scientific and technological information;

[0021] If the proportion of secondary information is the highest, the extraction unit is judged to have unqualified display layout for scientific and technological information, and the display time interval of the secondary information is changed;

[0022] If the proportion of the third-level information is the highest, the extraction unit is judged to be unqualified in the display layout of the scientific and technological information, and the display frequency of the third-level information is changed.

[0023] Furthermore, the analysis unit is used to change the display time interval of the secondary information, including:

[0024] To obtain and calculate the label matching degree of each secondary information and each tertiary information respectively, so as to determine whether to match the tertiary information with the corresponding secondary information based on the label matching degree;

[0025] The processing method for each information is determined based on the number of matching secondary information that matches a single tertiary information.

[0026] Furthermore, the analysis unit is used to calculate the label matching degree between the secondary information and the tertiary information, including:

[0027] The labels of the secondary information and the tertiary information are obtained respectively to calculate the ratio of the number of labels with overlapping contents to the total number of labels of a single secondary information, and the ratio is determined as the label matching degree;

[0028] The analyzing unit is used to determine whether to match the third-level information with the corresponding second-level information based on the tag matching degree, including:

[0029] If the tag matching degree is greater than the preset tag matching degree, the secondary information is matched with the tertiary information;

[0030] The analysis unit is used to determine a processing method for each information based on the number of matching second-level information that matches a single third-level information, including:

[0031] If the number of matches is zero, the single third-level information is used as the candidate third-level information;

[0032] If the number of matches is one, the display time of a single third-level information and the matching second-level information is replaced;

[0033] If the number of matches is greater than one, the secondary information with the highest label matching degree is replaced with the display time of the third-level information, and the remaining secondary information is determined as the candidate secondary information.

[0034] Furthermore, the analysis unit is used to change the display frequency of the third-level information, including:

[0035] Compare the content of each level 3 information with that of each level 1 information to determine whether there is any consistency in content;

[0036] For third-level information that is consistent with first-level information, it will be recorded as second-level information, and the display time interval of a single second-level information will be changed;

[0037] For the third-level information that does not have the same content as the first-level information, the similarity matching degree between the single third-level information and each first-level information is obtained, so as to adjust the display frequency of the single third-level information to the corresponding value based on the matching degree difference between the maximum value of each similarity matching degree and the preset label matching degree.

[0038] Furthermore, the analysis unit is used to calculate the similarity matching degree between a single third-level information and a single first-level information, including:

[0039] The labels of the third-level information and the first-level information are obtained respectively to calculate the ratio of the number of labels with overlapping contents to the total number of labels of a single first-level information, and the ratio is determined as the similarity matching degree;

[0040] The analysis unit is provided with several adjustment methods for adjusting the display frequency of a single third-level information based on the matching degree difference between the maximum value of each similar matching degree and the preset tag matching degree, and each adjustment method has a different adjustment range for the display frequency of the third-level information.

[0041] Compared with the prior art, the beneficial effect of the present invention lies in that the length of time that each portrait feature stays within the collection range of a collection unit during the display of scientific and technological information is obtained to divide the feature level of each portrait feature, and the information level of each scientific and technological information is determined according to the number of feature levels, and the display time interval and exhibition frequency of each scientific and technological information are coordinated according to the information level, thereby improving the display efficiency of scientific and technological information.

[0042] Furthermore, the feature levels of portrait features are divided based on the time length ratio, the information level of scientific and technological information is divided based on the feature levels, and when the number of primary features is less than or equal to the second preset number and greater than the first preset number, the information level of the scientific and technological information is determined by comprehensively analyzing the quantity ratio of primary features to secondary features. When the quantity ratio is less than or equal to the preset quantity ratio, the primary features account for a large proportion of each portrait feature, and the content is relatively attractive. However, there are fewer people in the environment when the scientific and technological information is exhibited, so the scientific and technological information with abnormal exhibition time intervals is marked as secondary information, and the reasons for the low attention of each scientific and technological information are determined in a targeted manner, so that the processing method is determined according to the specific reasons, which effectively improves the exhibition efficiency of scientific and technological information.

[0043] Furthermore, the proportion of information at each level is determined regularly, and when there is an abnormality in the attention of the currently exhibited scientific and technological information, it is handled in time. When the proportion of secondary information is the highest, since there is an abnormality in the exhibition time interval of the secondary information, the exhibition time interval of the secondary information is changed; the exhibition data of the current primary information is maintained, the exhibition time of the secondary information and the tertiary information is replaced, and the labels of the secondary information and the tertiary information are obtained. According to the label matching degree, the scientific and technological information with similar display content is replaced first. After completing the pairing of each secondary information, each tertiary information is checked. For a single tertiary information, statistics are counted with the tertiary information. The number of paired secondary information, if the number is zero, a single third-level data will be determined as the alternative third-level information; if the number is one, directly replace the corresponding secondary information and the third-level information's exhibition time interval, replace the secondary information with the wrong time exhibition interval, and then replace the third-level information with few viewers to the time interval with less traffic, and pair each third-level information with the secondary information in turn until the third-level information is completely matched. Because the number of secondary information is the largest now, there will be no third-level information left out after pairing. The exhibition time of each scientific and technological information is planned in a targeted manner, which effectively improves the effectiveness of the exhibition of each scientific and technological information.

[0044] Furthermore, for a single third-level information, check whether there is first-level information with the same content. If there is, record it as second-level information and change its display time interval. Since the content is the same, but there is scientific and technological information, it is determined to be first-level information. At this time, it indicates that the quality of the information content is fine, but the time interval is problematic and the display time interval can be directly replaced; if there is no first-level information with the same content, change the display frequency of the third-level information. Determine the user's interaction, based on the specific content of scientific and technological information, determine the display effect of different time periods, determine the comprehensive impact of time periods and content, determine the user preferences of a single area, and capture the changes in preferences in real time to coordinate the display content based on the changes in real time, effectively improving the real-time determination of the information preferences of target users in a single area, and further improving the efficiency of scientific and technological information display.

[0051] See also Figure 1 and Figure 2 As shown, they are respectively a module block diagram of a multimedia display system for scientific and technological information according to an embodiment of the present invention, and a flow chart of an analysis unit dividing the information level of a single scientific and technological information based on the number of primary features; a multimedia display system for scientific and technological information according to an embodiment of the present invention comprises:

[0052] A storage unit, which is used to store a number of scientific and technological information, each of which is provided with a corresponding label;

[0053] An extraction unit, connected to the storage unit, for selecting corresponding scientific and technological information from the storage unit;

[0054] An output unit connected to the extraction unit for displaying the scientific and technological information transmitted by the extraction unit;

[0055] A collection unit, which is arranged on the side wall of the output unit and is used to collect video information of the crowd around the output unit;

[0056] The analysis unit is connected to the storage unit, the extraction unit and the acquisition unit respectively, and uses the group video information to determine the dwell time of the portrait feature, and determines the attention feature rating based on the ratio of the dwell time of the portrait feature to the display time of the corresponding scientific and technological information based on the person. The attention feature rating includes primary features and secondary features. The information level of a single scientific and technological information is divided based on the number of primary features, or the ratio of the number of primary features to secondary features. The information level includes primary information, secondary information and tertiary information. Based on the statistical proportion of each information level, it is determined whether the exhibition layout of the scientific and technological information by the extraction unit is qualified, and when it is determined that the exhibition layout of the scientific and technological information by the extraction unit is unqualified, the exhibition time of the secondary information is replaced based on the matching degree of the secondary information and the tertiary information, or the exhibition frequency of the corresponding tertiary information is determined based on the similarity between the secondary information and the tertiary information.

[0057] Specifically, the length of time that each portrait feature stays within the collection range of the collection unit during the display of scientific and technological information is obtained to divide the feature level of each portrait feature, and the information level of each scientific and technological information is determined according to the number of feature levels. The display time interval and exhibition frequency of each scientific and technological information are coordinated according to the information level, thereby improving the display efficiency of scientific and technological information.

[0058] Specifically, scientific and technological information includes videos and images. There is no limitation on the selection method of each scientific and technological information label, which can be a keyword. It can be understood that the setting of keywords can be manually set in advance, image recognition can be performed on video information and image information to obtain corresponding keywords, or keyword extraction can be performed on text information in video information and image information. This is a prior art and will not be elaborated on.

[0059] Specifically, it should be pointed out that the data in this embodiment are obtained by comprehensive analysis and evaluation of the historical test data and the corresponding historical test results of the system of the present invention in the three months before the current test. The determination method of the system of the present invention for a single parameter can be to select the value with the highest proportion as the preset standard parameter according to the data distribution, use weighted summation to use the obtained value as the preset standard parameter or other selection methods, as long as the system of the present invention can clearly define different specific situations in the single determination process through the obtained values.

[0060] Specifically, the acquisition unit acquires portrait video information in front of the output unit and transmits the portrait video information to the analysis unit. The analysis unit extracts and locks portrait features from the video information, and records in turn the length of time that each portrait feature stays within the acquisition range of the acquisition unit during the display of scientific and technological information. For a single portrait feature, the ratio of the length of time the portrait feature stays to the length of time the scientific and technological information is displayed is calculated; if the length ratio is higher than a preset length ratio, the single portrait feature is recorded as a primary feature; if the ratio is less than or equal to the preset length ratio, the single portrait feature is recorded as a secondary feature.

[0061] Specifically, the preset duration ratio T0 is selected within the interval [0.07, 0.11].

[0062] Specifically, the specific structure of the acquisition unit is not limited, and it can be a camera. It can be understood that a camera is set on the side wall of the output unit. The camera collects portrait video information on the display side of the output unit to determine the attention level of the scientific and technological information output by the output unit. It will not be repeated here.

[0063] Specifically, there is no limitation on the method of extracting portrait features. The portrait features in the input portrait video information can be locked through the portrait recognition algorithm, and the length of time a single locked portrait feature stays in the portrait video information is recorded to determine the length of time the portrait feature stays. This is a prior art and will not be described in detail.

[0064] Specifically, the analysis unit divides the information level of a single piece of scientific and technological information based on the number of primary features, including:

[0065] If the number of first-level features is greater than the second preset number, the information level of the single scientific and technological information is determined to be first-level information;

[0066] If the number of primary features is less than or equal to the second preset number and greater than the first preset number, the information level of the single scientific and technological information is divided based on the ratio of the number of primary features to the number of secondary features corresponding to the single scientific and technological information;

[0067] If the number of the first-level features is less than or equal to the first preset number, the information level of the single scientific and technological information is determined as third-level information.

[0068] Specifically, the first preset number U1 is selected within the interval [0.15A0, 0.18A0], the second preset number U2 is selected within the interval [0.27A0, 0.3A0], and A0 is the average value of the number of portrait features corresponding to each historical scientific and technological information.

[0069] Specifically, the analysis unit divides the information level of the single scientific and technological information based on the quantity ratio of the primary feature to the secondary feature corresponding to the single scientific and technological information, including:

[0070] If the quantity ratio is less than or equal to the preset quantity ratio, the information level of the single scientific and technological information is classified as secondary information;

[0071] If the quantity ratio is greater than the preset quantity ratio, the information level of the single scientific and technological information will be divided into three levels of information.

[0072] Specifically, the quantity ratio B0 is selected within the interval [0.35, 0.55].

[0073] Specifically, the feature levels of portrait features are divided based on the time length ratio, and the information level of scientific and technological information is divided based on the feature levels. When the number of first-level features is less than or equal to the second preset number and greater than the first preset number, the information level of the scientific and technological information is determined by comprehensively analyzing the number ratio of first-level features to second-level features. When the number ratio is less than or equal to the preset number ratio, the first-level features account for a large proportion of each portrait feature, and the content is relatively attractive. However, there are fewer people in the environment when the scientific and technological information is exhibited, so the scientific and technological information with abnormal exhibition time intervals is marked as second-level information, and the reasons for the low attention to each scientific and technological information are determined in a targeted manner, so that the processing method is determined according to the specific reasons, which effectively improves the exhibition efficiency of scientific and technological information.

[0074] Specifically, the analysis unit is used to determine whether the display layout of the scientific and technological information by the extraction unit is qualified based on the statistical proportion of each information level, including:

[0075] If the proportion of primary information is the highest, then the extraction unit is judged to have qualified display layout for scientific and technological information;

[0076] If the proportion of secondary information is the highest, the extraction unit is judged to have unqualified display layout for scientific and technological information, and the display time interval of the secondary information is changed;

[0077] If the proportion of the third-level information is the highest, the extraction unit is judged to be unqualified in the display layout of the scientific and technological information, and the display frequency of the third-level information is changed.

[0078] Specifically, the analysis unit is used to change the display time interval of the secondary information, including:

[0079] To obtain and calculate the label matching degree of each secondary information and each tertiary information respectively, so as to determine whether to match the tertiary information with the corresponding secondary information based on the label matching degree;

[0080] The processing method for each information is determined based on the number of matching secondary information that matches a single tertiary information.

[0081] Specifically, the proportion of information at each level is determined regularly, and when there is an abnormality in the attention paid to the currently exhibited scientific and technological information, it is handled in a timely manner. When the proportion of secondary information is the highest, the exhibition time interval of the secondary information is changed because there is an abnormality in the exhibition time interval of the secondary information; the exhibition data of the current primary information is maintained, the exhibition time of the secondary information and the tertiary information is replaced, the labels of the secondary information and the tertiary information are obtained, and the scientific and technological information with similar display content is replaced first according to the label matching degree. After completing the pairing of each secondary information, each tertiary information is checked. For a single tertiary information, statistics are counted with the tertiary information The number of paired secondary information, if the number is zero, a single third-level data will be determined as the alternative third-level information; if the number is one, directly replace the corresponding secondary information and the third-level information's exhibition time interval, replace the secondary information with the wrong time exhibition interval, and then replace the third-level information with few viewers to the time interval with less traffic, and pair each third-level information with the secondary information in turn until the third-level information is completely matched. Because the number of secondary information is the largest now, there will be no third-level information left out after pairing. The exhibition time of each scientific and technological information is planned in a targeted manner, which effectively improves the effectiveness of the exhibition of each scientific and technological information.

[0082] Specifically, the analysis unit is used to calculate the label matching degree between the secondary information and the tertiary information, including:

[0083] The labels of the secondary information and the tertiary information are obtained respectively to calculate the ratio of the number of labels with overlapping contents to the total number of labels of a single secondary information, and the ratio is determined as the label matching degree;

[0084] The analyzing unit is used to determine whether to match the third-level information with the corresponding second-level information based on the tag matching degree, including:

[0085] If the tag matching degree is greater than the preset tag matching degree, the secondary information is matched with the tertiary information.

[0086] The analysis unit is used to determine a processing method for each information based on the number of matching second-level information that matches a single third-level information, including:

[0087] If the number of matches is zero, the single third-level information is used as the candidate third-level information;

[0088] If the number of matches is one, the display time of a single third-level information and the matching second-level information is replaced;

[0089] If the number of matches is greater than one, the secondary information with the highest label matching degree is replaced with the display time of the third-level information, and the remaining secondary information is determined as the candidate secondary information.

[0090] Specifically, the preset label matching degree Q is selected within the interval [0.6, 0.7].

[0091] Specifically, for a single third-level information, check whether there is first-level information with the same content. If there is, record it as second-level information and change its display time interval. Since the content is the same, but there is scientific and technological information, it is determined to be first-level information. At this time, it indicates that the quality of the information content is fine, but the time interval is problematic and the display time interval can be directly replaced; if there is no first-level information with the same content, change the display frequency of the third-level information. Determine the user's interaction, based on the specific content of scientific and technological information, determine the display effect of different time periods, determine the comprehensive impact of time periods and content, determine the user preferences of a single area, and capture the changes in preferences in real time to coordinate the display content based on the changes in real time, effectively improving the real-time determination of the information preferences of target users in a single area and further improving the efficiency of scientific and technological information display.

[0092] Specifically, the analysis unit is used to change the display frequency of the third-level information, including:

[0093] Compare the content of each level 3 information with that of each level 1 information to determine whether there is any consistency in content;

[0094] For third-level information that is consistent with first-level information, it will be recorded as second-level information, and the display time interval of a single second-level information will be changed;

[0095] For the third-level information that does not have the same content as the first-level information, the similarity matching degree between the single third-level information and each first-level information is obtained, so as to adjust the display frequency of the single third-level information to the corresponding value based on the matching degree difference between the maximum value of each similarity matching degree and the preset label matching degree.

[0096] Specifically, the analysis unit is used to calculate the similarity matching degree between a single third-level information and a single first-level information, including:

[0097] The labels of the third-level information and the first-level information are obtained respectively to calculate the ratio of the number of labels with overlapping contents to the total number of labels of a single first-level information, and the ratio is determined as the similarity matching degree;

[0098] The analysis unit is provided with a plurality of adjustment methods for adjusting the display frequency of a single third-level information based on the difference between the maximum value of each similarity matching degree and the preset tag matching degree, and each adjustment method has a different adjustment range for the display frequency of the third-level information.

[0099] Specifically, the matching degree difference value P is compared with the preset first matching degree difference value P1 and the second matching degree difference value P2.

[0100] If P≤P1, the display frequency of the third-level information is determined as the first display frequency F1, and F1=0.7F0;

[0101] If P1<P≤P2, the display frequency of the third-level information is determined as the second display frequency F2, and F2=0.8F0;

[0102] If P>P2, the display frequency of the third-level information is determined as the third display frequency F3, and F3=0.9F0;

[0103] Among them, F0 is the initial display frequency, P1=0.07Q, P2=0.16Q.
