[0002] In order to intuitively display the construction target values and progress, a project progress management display device is generally used to facilitate the control and management of the construction progress.

[0003] However, for the existing project progress management devices, the staff needs to manually replace the progress table. Since the project construction progress changes rapidly, the method of manually replacing the progress table will result in untimely replacement and update of the progress table, thus causing the staff to be unable to accurately manage the project progress. In severe cases, it will also affect the construction period.

[0004] The existing CN114974012B project progress management device for construction project management discloses that the display device can also be applied to projects such as power engineering. However, its method of replacing the progress table still uses a mechanical structure, that is, the progress table is printed out and then the old and new are replaced through an automatic replacement device. Its display content only targets the progress table and cannot display richer content. Therefore, it cannot display different content of concern to different viewers according to different viewers. Summary of the Invention

[0031] The following describes the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only for explaining and illustrating the present invention, and are not used to limit the present invention.

[0032] An embodiment of the present invention provides an information display system for engineering project management, as Figure 1 shown, including: a scene analysis module 1, a control module 2, and a display module 3;

[0033] Among them, the scene analysis module 1 analyzes the image in front of the display module to analyze the current display scene; the control module 2 retrieves the display strategy and display data according to the current display scene and controls the display module 3 to perform display according to the display strategy and display data;

[0034] Among them, the current display scene includes a multi-person display; the display data includes: the content of interest corresponding to each viewer; the display strategy includes: displaying the content of interest corresponding to each viewer to the position in the line of sight.

[0035] Among them, the display module includes: a large-screen display.

[0036] Among them, the scene analysis module includes: a camera and an image processor.

[0037] Among them, the analysis steps of the current display scene include:

[0038] Extract the human body contour in the image, the facial area of the human body contour, and the line-of-sight direction corresponding to each human body contour;

[0039] When no human body contour is extracted, it is determined that the current display scene is a static display;

[0040] When a human body contour is extracted and the line-of-sight directions all fall on the facial areas of the human body contours on the display module and none of them are identified as engineering-related personnel, it is determined that the current display scene is a static display;

[0041] When a human body contour is extracted, the line-of-sight directions all fall on the facial areas of the human body contours on the display module and all of them are identified as engineering-related personnel, and the number of engineering-related personnel is greater than one, it is determined that the current display scene is a multi-person display;

[0042] When a human body contour is extracted, the line-of-sight directions all fall on the facial areas of the human body contours on the display module and all of them are identified as engineering-related personnel, and the number of engineering-related personnel is one, it is determined that the current display scene is a single-person display;

[0043] When a human body contour is extracted, the line-of-sight directions do not all fall on the facial areas of the human body contours on the display module and not all of them are identified as engineering-related personnel, and the number of engineering-related personnel is one, it is determined that the current display scene is a mixture of single-person display and static display;

[0044] When a human body contour is extracted, the line-of-sight directions do not all fall on the facial areas of the human body contours on the display module and not all of them are identified as engineering-related personnel, and the number of engineering-related personnel is greater than one, it is determined that the current display scene is a mixture of multi-person display and static display.

[0045] For the current display scene being a static display, the display strategy is a static display; the display data includes: a pre-configured engineering project introduction page.

[0046] The display strategy corresponding to the single-person display is a dynamic display; the display data is to retrieve the associated data according to the work number of the engineering-related personnel.

[0047] For the mixture of single-person display and static display or multi-person display and static display, the display strategy is to perform a single-person display or multi-person display in suspension with the pre-configured engineering project introduction page as the floor (background).

[0048] The working principle and beneficial effects of the above technical solution are:

[0049] The information display system for engineering project management according to the present invention comprehensively analyzes the number of people in front of the large-screen display, the identities of the people, and the line of sight of the people to determine the current display scenario; for different display scenarios, different display strategies are adopted; in addition, different display contents are also displayed according to different people, enriching the display contents and being able to display different contents concerned by different viewers. In the system, the contents concerned by each person are configured according to their different identities. For example, when the person is a construction worker, the contents concerned are configured as the work arrangement for the current day and / or the work arrangement for the next day, and the position of the person in the work arrangement is highlighted and centered in that area; when the person is a person in charge, the contents concerned are configured as the project progress schedule, etc.

[0050] Among them, when extracting the human contour, it is necessary to query the pre-configured allowable size threshold range determination table according to the position of the center of the human contour in the image to determine the allowable threshold range to screen the human contour, so as to eliminate interference factors such as people far away from the display module and children, improving the accuracy of display control; among them, the allowable threshold range is the allowable range of pixels occupied in the width and length directions of the human contour.

[0051] Among them, the determination steps for whether the line-of-sight direction corresponding to the human body contour falls on the display module include: retrieving the line-of-sight angle determination library corresponding to the position where the human body contour is located according to the position of the human body contour; extracting features of the human body contour and constructing a first analysis parameter set based on the extracted contour features; retrieving a first angle range from a pre-configured first angle range determination library according to the first analysis parameter set; extracting the facial area of the human body contour to obtain the facial area; extracting features of the facial area and constructing a second analysis parameter set, and retrieving a second angle range from a pre-configured second angle range determination library according to the second analysis parameter set; taking the intersection of the second angle range and the second angle range as the interval range where the line-of-sight angle corresponding to the human body contour is located; when the ratio of the part of the interval range where the line-of-sight angle is located and that falls within the verification interval (the verification interval consists of all angles where the line of sight at this position falls on the display module) associated with the position where the human body contour is located to the interval range is greater than a preset ratio (0.5 to 1), it is determined that the line-of-sight direction falls on the display module. Among them, the parameters in the first analysis parameter set include: parameters representing the height of the human body contour, parameters representing the shoulder width in the human body contour, parameters representing the hand length in the human body contour, parameters representing the head length in the human body contour, etc.; the first angle range determination library is pre-constructed by professionals for the point analysis corresponding to each position in the image, and the first analysis parameter set in the first angle range determination library is associated with the first angle range; the parameters in the second analysis parameter set include: parameters representing the area size of the facial area, parameters representing the coordinates of the tip of the nose, parameters representing the distance between the two eyes, parameters representing the coordinates of the center point between the two eyebrows, etc.; the second angle range determination library is pre-constructed by professionals for the point analysis corresponding to each position in the image, and the second analysis parameter set in the second angle range determination library is associated with the second angle range.

[0052] During the display process of the display module, there will be situations such as leadership inspections or customer receptions. Whether it is accompanied by multiple people or single person, it is determined that the current display is not applicable to the current scenario. In one embodiment, as Figure 2 shown, the information display system for engineering project management further includes: an association analysis module 4, which is used to analyze the association between each human body contour to facilitate the associated display of the control module;

[0053] Among them, as Figure 3 shown, the association analysis module 4 performs the following operations:

[0054] Step 1: Based on the time when each human body contour first appears in the image, perform an association as an analysis group;

[0055] First, it is necessary to analyze the time when the leadership inspection or customer reception occurs to exclude the time when the vast majority of workers can appear in front of the display device. Therefore, it is necessary to limit the human body contours that appear outside the preset time periods (half an hour before the construction workers start work until the start time of work, the end time of work until half an hour after the end time of work, the noon break time, etc.). When the time difference between the appearance times of two human body contours is less than or equal to the preset time threshold (any value from 10 seconds to 2 minutes), these human body contours can be associated as an analysis group;

[0056] Step 2: Identify the identities of the personnel corresponding to the human body contours in the analysis group;

[0057] In the inspection scenario or customer reception scenario, there are usually engineering-related staff for accompaniment. Therefore, identify the identities of the personnel in the analysis group to determine whether there are engineering-related staff in the analysis group;

[0058] Step 3: When there are no personnel in the preset reception personnel library, determine that there is no association between the human body contours in the analysis group;

[0059] In the case of leadership inspection or customer reception, it is generally accompanied by engineering-related staff. There is a reception personnel library configured in the system in advance, and the reception personnel library stores the personnel for reception and accompaniment; when not identified, it means that the association that the association analysis module wants to analyze does not exist, and it can be determined that there is no association between the human body contours;

[0060] Step 4: When there are personnel in the preset reception personnel library, arrange the non-engineering-related personnel in the analysis group in the order of the time of first appearance in the image to form an analysis queue;

[0061] Generally, the target of the reception is non-engineering-related personnel stored in the system. Therefore, there is no need to further analyze whether the relevant staff are core figures;

[0062] Step 5: Sequentially extract the human body contours of the personnel in the analysis queue from the first appearance in the image until the movement stops as behavior analysis data;

[0063] By analyzing a series of images of the human body contour areas when the personnel enter the image, their behaviors can be analyzed; in this way, by analyzing their behaviors, it can be indirectly judged whether they are the core figures of this reception, and targeted display can be realized;

[0064] Step 6: Analyze the core figures based on the behavior analysis data;

[0065] The specific analysis steps are as follows: Extract features from the behavior analysis data, construct an analysis parameter set based on the extracted features, and retrieve the corresponding possibility values from the pre-configured possibility value library according to the analysis parameter set; then, according to the pre-configured weight coefficient table, determine the weight coefficient corresponding to the analysis queue order; the person with the largest product of the weight coefficient and the possibility value is taken as the core person; among them, the parameters in the analysis parameter set include: parameters representing the time when the line of sight falls on other individuals, parameters representing dressing characteristics, parameters representing whether conversations occur with other individuals and the conversation time, etc.; the possibility values in the possibility value library are in one-to-one correspondence with the analysis parameter set; the weight coefficient table is configured with the weight coefficients corresponding to each order, and the weight coefficient of the previous order is greater than that of the subsequent order.

[0066] Step 7: Associate other non-engineering-related personnel whose distance from the core person is within the preset distance threshold as accompanying personnel; associate engineering-related personnel whose distance from the core person is within the preset distance threshold as escort personnel;

[0067] Among them, the distance threshold is any value from 1 meter to 5 meters; after grouping and analyzing personnel for association, the control module displays through the pre-configured display data (slide presentation document) corresponding to the person with the highest authority among the engineering-related personnel in the associated personnel, and with the explanation of the commentator among the escort personnel, to better present the project situation to customers or leaders.

[0068] In order to balance energy conservation and display functions, in one embodiment, the information display system for project management also includes: a sleep module, which is used to analyze the situation in front of the display module to determine whether to enter the sleep mode or activate the display; in the sleep mode, the control module does not display; in the activation display mode, the control module displays;

[0069] Among them, the analysis steps of the sleep module for the situation in front of the display module are as follows:

[0070] When no human contour is recognized in the image, start timing, and when the timing reaches the sleep threshold, enter the sleep mode;

[0071] In the sleep mode, when a human contour is recognized in the image, analyze the behavior of the human contour, and determine whether to enter the activation display according to the analysis result;

[0072] Among them, the behavior analysis of the human contour includes:

[0073] Determine whether it points to the display module according to the moving direction of the position at the previous moment and the next moment; when it points, enter the activation display mode, otherwise, do not enter;

[0074] And / or,

[0075] Determine whether the time ratio of the line of sight falling on the display module during the movement of the human body contour is greater than a preset ratio threshold; when it is greater, enter the active display mode, otherwise, do not enter.

[0076] By comprehensively analyzing the line of sight and the moving direction, the intention of the person corresponding to the human body contour can be judged more accurately, so as to improve the accuracy of the judgment of activating and deactivating the sleep state based on the line of sight. Among them, the time ratio is the ratio of the time when the line of sight falls on the display module to the total movement time, and the time ratio judgment is only carried out when the total movement time is greater than a preset time (any value from 10 seconds to 1 minute).

[0077] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
