[0004] The system of the above patent is universal, has strong scalability, is convenient for users to customize according to the actual situation, makes big data display more personalized, is applicable to a variety of application scenarios, and reduces the development cost of big data visualization display. However, since there will be different degrees of display effects when data is displayed, if a single display effect is presented, it will cause a waste of resources, and the above patent does not conduct good adjustment and analysis in combination with the actual situation. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a big data and visual three-dimensional display system for overall territorial space planning, which solves the problem that a single display method does not reasonably adjust and analyze the display effect in combination with the actual situation.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A big data and visual three-dimensional display system for overall territorial space planning, including:

[0007] The information intelligent acquisition terminal is used to present the basic information corresponding to the three-dimensional display data. The basic information includes the display location, display time, and display clarity, and transmits the obtained basic information to the display situation analysis terminal. The display location indicates the display of the big data of the overall territorial space planning at the corresponding location, such as in a hall, elevator, shopping mall, or a series of other places. The display time represents the playback time of the overall territorial space planning, and the playback time is in a loop, specifically the time interval between single-loop playbacks.

[0008] The display situation analysis terminal is used to obtain the transmitted display location and display time information, and at the same time analyze it in combination with the personnel corresponding to the display location. Classify the passing personnel into concerned personnel and unconcerned personnel, and judge whether it is necessary to adjust the display clarity according to the number of the two, and generate judgment information at the same time. The judgment information includes the result of needing adjustment and the result of not needing adjustment, and the specific method of generating judgment information is as follows:

[0009] S1: Obtain different display screens in the display location, number them and record them as i, and i = 1, 2,..., j. Then obtain the display areas corresponding to different display screens and record them as Qi, and mark the overlapping display intervals of adjacent display screens as overlapping areas; specifically, for a showroom, there will be different display screens inside the showroom, and the content played on the display screens is also different. The display areas corresponding to different display screens are also different.

[0010] S2: Then obtain the target display screen and its adjacent display screens, and at the same time obtain the target display area, non-target display area, and overlapping area. Then obtain the video surveillance and identify its content, and obtain the number of people corresponding to the display location as R according to the content. At the same time, obtain the number of people corresponding to the target display area, non-target display area, and overlapping area as Rm, Rn, and Rc respectively;

[0011] S3: Obtain the number of people Rc in the overlapping area and obtain the video surveillance in the overlapping area. Then analyze and judge the personnel in the overlapping area according to the video surveillance, and classify them into concerned personnel and unconcerned personnel. The specific analysis method is as follows:

[0012] S31: Collect the personnel information in the video surveillance. At the same time, establish a rectangular coordinate system with the shoulders of the personnel as the abscissa and the head as the ordinate, and then analyze the head movements of the personnel;

[0013] S32: When there is a horizontal rotation angle between the person's head and the rectangular coordinate system, determine the direction corresponding to the head. If the direction corresponding to the head is the target display area, then determine whether there is an up-and-down rotation angle of the head. If there is, it means that the person's line of sight range matches the target display area, and mark this person as a concerned person. If not, mark this person as a non-concerned person. If the rotation direction corresponding to the head is a non-target display area, mark the person as a non-concerned person;

[0014] S4: Obtain all concerned persons and non-concerned persons, and correspondingly obtain their numbers denoted as R1 and R2, and compare the two. When R1 ≥ R2, it means that the number of concerned persons exceeds the number of non-concerned persons, and at the same time generate an adjustment result. On the contrary, when R1 < R2, it means that the number of concerned persons does not exceed the number of non-concerned persons, and at the same time generate a result of not requiring adjustment. Specifically, by comparing the number of concerned persons and non-concerned persons in the exhibition hall with each other, it is judged whether the target display screen needs to be adjusted accordingly.

[0015] The information adjustment display end is used to obtain the transmitted judgment information, analyze the generated adjustment result, analyze the current clarity of the target display screen, and make a reasonable adjustment by comprehensively considering the change situation of the number of concerned persons, and generate adjustment information. At the same time, transmit the adjustment information to the adjustment information output end, and the specific method of generating the adjustment information is as follows:

[0016] P1: Obtain the adjustment standard of clarity, obtain the current clarity transmitted by the real-time data acquisition end, and then obtain the change situation of the number of concerned persons within the time period t. When the number of concerned persons increases, calculate the increase amount within the time period t denoted as Z. When the number of concerned persons decreases, calculate the decrease amount X within the cycle time t; Specifically, the current clarity is defaulted to high-definition playback.

[0017] P2: Then obtain the increase amount Z and the decrease amount X, and analyze the two to generate corresponding adjustment information, and the specific analysis method is as follows:

[0018] The specific method of analyzing the increase amount Z is as follows:

[0019] Obtain the current clarity and judge whether it can be further increased. If it cannot be further increased, do not process and maintain the current clarity. If it can be further increased, substitute the increase amount Z and the number of persons R within the cycle time t into the formula Calculate the adjustment value Q, and then match the adjustment value Q with the preset value Qy, judge the specific interval where the adjustment value Q is located, and generate adjustment information according to the matching result.

[0020] The specific method for analyzing the reduction amount X is the same as that for analyzing the increase amount, and adjustment information is generated according to the matching result.

[0021] P3: Then, the real-time data transmitted by the real-time data acquisition end is obtained, and based on the real-time data, secondary adjustment analysis is performed on the adjusted target display screen, and secondary adjustment information is generated at the same time. The specific generation method is as follows:

[0022] The change situation of the concerned personnel within the time period t1 is obtained. If the number of concerned personnel increases, the clarity is not adjusted, and normal information is generated. On the contrary, if the number of concerned personnel decreases, the change amount of the concerned personnel per unit time is calculated and denoted as Rb, and it is compared with the preset value Ry. If Rb≥Ry, it means that the decrease value of the number of concerned personnel exceeds the preset value, and at the same time, decrease adjustment information is generated. On the contrary, if Rb<Ry, it means that the decrease value of the number of concerned personnel does not exceed the preset value, and at the same time, normal information is generated. Specifically, the specific definition of the unit time is taken according to the actual situation, which can be one hour, half an hour, or two hours. The specific value is determined by the operator. At the same time, the preset value Ry is also set by the operator.

[0023] The adjustment information output end is used to obtain the transmitted adjustment information and secondary adjustment information, and display them to the operator through the display device.

[0025] The present invention provides a big data and visual three-dimensional display system for overall territorial space planning. Compared with the prior art, it has the following beneficial effects:

[0026] The present invention adjusts the display effect corresponding to the current display screen according to the number of people in the exhibition hall. By classifying the people in the exhibition hall into concerned personnel and unconcerned personnel, further judging whether adjustment is needed according to the change situation of the number of concerned personnel, and making specific adjustments according to the specific quantity change value. By adjusting the display effect in this way, the overall resource consumption can be reduced when the number of people is small, so as to achieve the purpose of energy saving. Brief description of the drawings

[0028] Figure 2 It is the schematic diagram of the exhibition area of the present invention. Specific implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1 and Figure 2 , this application provides a big data and visual three-dimensional display system for overall territorial space planning, including: an information intelligent acquisition end, a display situation analysis end, an information display adjustment end, a real-time data acquisition end, and an adjustment information output end.

[0031] The information intelligent acquisition end is used to obtain the basic information corresponding to the three-dimensional display data, where the basic information includes the display location, display time, and display clarity, and transmits the obtained basic information to the display situation analysis end. The display location represents the display of the overall territorial space planning big data at the corresponding location, such as in the hall, elevator lobby, or shopping mall, etc. A series of places, and the display time represents the playback time of the overall territorial space planning, and the playback time is represented by loop playback, specifically the time interval between single loop playbacks.

[0032] The display situation analysis end is used to obtain the transmitted display location and display time information, and at the same time analyze it in combination with the personnel corresponding to the display location. By classifying the passing personnel into concerned personnel and unconcerned personnel, and judging whether it is necessary to adjust the display clarity according to the number of the two, and at the same time generate judgment information, the judgment information includes the need to adjust the result and the need not to adjust the result, and the specific way of generating the judgment information is as follows:

[0033] S1: Obtain different display screens in the display location, number them and record them as i, and i = 1, 2,..., j. Then obtain the display areas corresponding to different display screens and record them as Qi, and mark the overlapping display intervals of adjacent display screens as overlapping areas; specifically, for a showroom, there will be different display screens inside the showroom, and the content played on the display screens is also different. The display areas corresponding to different display screens are also different.

[0034] Combined with actual analysis, as shown in the appendix Figure 2As shown, there are currently two display screens, namely the first display screen and the second display screen, and the two display screens respectively correspond to two display areas, the first display area and the second display area. The display area represents the content radiation range corresponding to the display screen, and the displayed content can be seen anywhere within this display area. At the same time, it can be known from the attached drawings that there is an overlapping area between the first display area and the second display area. Therefore, the overlapping area is marked as the overlapping region. At the same time, it is default that the visual range of the personnel is certain, and the data is prior art and can be directly obtained.

[0035] S2: Then obtain the target display screen and its adjacent display screens. At the same time, obtain the target display area, non-target display area, and overlapping area. Then obtain the video surveillance and identify its content, and record the number of people corresponding to the display location as R according to the content. At the same time, record the number of people corresponding to the target display area, non-target display area, and overlapping area as Rm, Rn, and Rc respectively;

[0036] S3: Obtain the number of people Rc in the overlapping area and obtain the video surveillance within the overlapping area. Then analyze and judge the personnel in this overlapping area according to the video surveillance, and classify them as concerned personnel and non-concerned personnel. The specific analysis method is as follows:

[0037] S31: Collect the personnel information in the video surveillance. At the same time, establish a rectangular coordinate system with the shoulders of the personnel as the abscissa and the head as the ordinate. Then analyze the head movements of the personnel;

[0038] S32: When there is a horizontal rotation angle between the head of the personnel and the rectangular coordinate system, judge the direction corresponding to the head. If the direction corresponding to the head is the target display area, then judge whether there is a vertical rotation angle of the head. If it exists, it means that the visual range of the personnel matches the target display area, and mark this personnel as a concerned personnel. If it does not exist, mark this personnel as a non-concerned personnel. If the rotation direction corresponding to the head is the non-target display area, mark the personnel as a non-concerned personnel;

[0039] Combined with the actual analysis, the display screen at the display location has a certain height. When personnel need to watch the displayed content, they need to look up. At the same time, the amplitude of looking up may be large or small, both are possible. Therefore, when personnel are in the overlapping area, it is necessary to comprehensively judge the personnel in combination with the corresponding horizontal rotation direction and vertical rotation direction.

[0040] S4: Obtain all followed persons and non - followed persons, and correspondingly obtain their numbers denoted as R1 and R2, and compare the two. When R1 ≥ R2, it indicates that the number of followed persons exceeds the number of non - followed persons, and at the same time generate an adjustment result. On the contrary, when R1 < R2, it indicates that the number of followed persons does not exceed the number of non - followed persons, and at the same time generate a result of not requiring adjustment. Specifically, by comparing the number of followed persons and non - followed persons in the exhibition hall with each other, it is determined whether the target display screen needs to be adjusted accordingly.

[0041] The information adjustment display terminal is used to obtain the transmitted judgment information, analyze the generated adjustment result, analyze the current clarity of the target display screen, and at the same time make a reasonable adjustment by comprehensively considering the change in the number of followed persons, and generate adjustment information. Then, the adjustment information is transmitted to the adjustment information output terminal, and the specific way of generating the adjustment information is as follows:

[0042] P1: Obtain the adjustment standard of clarity, obtain the current clarity transmitted by the real - time data acquisition terminal, and then obtain the change in the number of followed persons within the time period t. When the number of followed persons is increasing, calculate the increase amount denoted as Z within the time period t. When the number of followed persons is decreasing, calculate the decrease amount X within the time period t. Specifically, the current clarity is defaulted to high - definition playback.

[0043] P2: Then obtain the increase amount Z and the decrease amount X, and analyze the two to generate corresponding adjustment information, and the specific analysis method is as follows:

[0044] The specific method for analyzing the increase amount Z is as follows:

[0045] Obtain the current clarity and determine whether it can be further increased. If it cannot be further increased, no processing is performed and the current clarity is maintained. If it can be further increased, substitute the increase amount Z and the number of persons R within the time period t into the formula Calculate the adjustment value Q, and then match the adjustment value Q with the preset value Qy, determine the specific interval where the adjustment value Q is located, and generate adjustment information according to the matching result.

[0046] The specific method for analyzing the decrease amount X is the same as that for analyzing the increase amount, and generate adjustment information according to the matching result.

[0047] Combined with actual analysis, there are four levels for the clarity adjustment standard, namely: standard definition, high definition, ultra-high definition, and original painting. Moreover, the data processing steps corresponding to the four levels are different, and the adjustment values Qy corresponding to the four levels also vary. When the calculated adjustment value Q is within the ultra-high definition range, the current clarity is adjusted to ultra-high definition. When the calculated adjustment value Q is within the original painting range, the current clarity is adjusted to original painting. The above is for the case where adjustment is possible, while for the case where adjustment is not possible, the current clarity is maintained and the video continues to play.

[0048] P3: Then, obtain the real-time data transmitted by the real-time data acquisition end, and perform secondary adjustment analysis on the adjusted target display screen according to the real-time data, and generate secondary adjustment information at the same time. The specific generation method is as follows:

[0049] Obtain the change situation of the concerned personnel within the time period t1. If the number of concerned personnel increases, the clarity is not adjusted, and normal information is generated. On the contrary, if the number of concerned personnel decreases, calculate the change amount of the concerned personnel per unit time, denoted as Rb, and compare it with the preset value Ry. If Rb≥Ry, it means that the decrease value of the number of concerned personnel exceeds the preset value, and at the same time, decrease adjustment information is generated. On the contrary, if Rb<Ry, it means that the decrease value of the number of concerned personnel does not exceed the preset value, and at the same time, normal information is generated. Specifically, the specific definition of the unit time is determined according to the actual situation and can be one hour, half an hour, or two hours. The specific value is determined by the operator. At the same time, the preset value Ry is also set by the operator.

[0050] The adjustment information output end is used to obtain the transmitted adjustment information and secondary adjustment information and display them to the operator through the display device.

[0051] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0052] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
