[0045] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0046] As shown in Figure 1 The embodiments of the present application disclose a construction monitoring method based on BIM, the method comprises the following steps:

[0047] Constructing a basic BIM model of the construction site, the basic BIM model comprising a first building BIM model, a first material BIM model, a first person and vehicle BIM model;

[0048] Obtaining monitoring data of a monitoring system of the construction site, the monitoring data comprising a first monitoring video, first material electronic information, and constructing a second building BIM model, a second material BIM model, and a second person and vehicle BIM model according to the first monitoring video and the first material electronic information;

[0049] The second building BIM model, the second material BIM model and the second person-vehicle BIM model are used to replace the first building BIM model, the first material BIM model and the first person-vehicle BIM model in the basic BIM model respectively, so that a dynamic BIM model of the construction site is obtained.

[0050] The method further comprises:

[0051] If the second building BIM model of the target building and the second material BIM model of the target material fail to be constructed, second monitoring videos associated with the target building and the target material which fail to be constructed are obtained.

[0052] The second building BIM model and the second material BIM model are constructed according to the predicted real-time data of the target building and the target material which are deduced according to the second monitoring videos.

[0053] The basic BIM model of the construction site is first constructed, and the basic BIM model comprises a building BIM model, a material BIM model and a person-vehicle BIM model, which correspond to buildings, building materials (such as sand, cement and steel bars) in a stacking field, construction personnel and construction vehicles of the construction site respectively.

[0054] Then, first monitoring data of a monitoring system of the construction site are obtained in real time during the construction of the construction site, and the monitoring system comprises a video monitoring system and a material electronic management system, so that first monitoring videos and first material electronic information are obtained respectively. Real-time internal and external structure data of each building in the construction site can be obtained according to the monitoring videos, and a latest second building BIM model is constructed; real-time conditions of building materials in the stacking field can be determined according to the monitoring videos and the material electronic management system, and a second material BIM model of the building materials is constructed; dynamic and static information (such as position and speed) of the construction personnel and the construction vehicles in the construction site can be obtained according to the monitoring videos, and a second person-vehicle BIM model is constructed.

[0055] Finally, the second building BIM model, the second material BIM model and the second person-vehicle BIM model are replaced in the corresponding positions in the basic BIM model respectively, so that the basic BIM model is updated, and a dynamic BIM model of the construction site is obtained.

[0056] The video monitoring system cannot cover all areas of the construction site 100% due to various factors (e.g. camera damage in the area), resulting in failure to update the BIM model of some BIM objects, such as failure to construct the second building BIM model of the target building and the second material BIM model of the target material. To solve this problem, the present application further provides the following processing method, specifically:

[0057] Obtain the second monitoring video associated with the target building for which the construction fails and the target material for which the construction fails. Here, the second monitoring video obtained is, for example, the monitoring video of each associated area associated with the area where the target building or the target material is located. According to the second monitoring video, the predicted real-time data of the target building and the target material can be inferred. According to the predicted real-time data, the second building BIM model of the target building and the second material BIM model of the target material are constructed. Thus, the successful update of the BIM model in the case of missing monitoring video is realized.

[0058] Therefore, the scheme of the present application can automatically construct and update the BIM model of the construction site, so that the management personnel can intuitively understand the real-time dynamics of the construction site. At the same time, the scheme of the present application can also effectively deal with the update of the BIM model in the case of missing monitoring video, so as to ensure that the BIM model of the construction site can always keep the latest dynamics.

[0059] Optionally, the construction of the basic BIM model of the construction site comprises:

[0060] Receiving or accessing an electronic planning drawing containing planning information of the construction site by electronic means, the electronic planning drawing containing information about planning details of each area of the construction site;

[0061] Analyzing and processing the electronic planning drawing by computer algorithm and / or software tool to extract the construction planning information about each area of the construction site, including but not limited to the position, size, structure type, material specification of the building and the functional division of each area;

[0062] According to the extracted construction planning information, the basic BIM model of the construction site is constructed by using BIM modeling software, and the basic BIM model includes the first building BIM model and the first material BIM model.

[0063] In this embodiment, the above-mentioned basic BIM model contains detailed three-dimensional representations of each area of the construction site, i.e. a plurality of first building BIM models and first material BIM models.

[0064] The BIM modeling software preferably uses Autodesk Revit, Bentley OpenRoads, and Graphisoft ArchiCAD. Among them, Autodesk Revit: As one of the most popular BIM software, Revit is widely used in architecture, structure and mechanical and electrical fields, providing comprehensive modeling and design functions. Bentley OpenRoads: Focuses on road design, suitable for civil engineers, providing powerful road modeling and analysis tools. Graphisoft ArchiCAD: Provides a flexible design environment for architects, emphasizing creativity and design freedom.

[0065] Optionally, the base BIM model of the construction site further comprises:

[0066] A third monitoring video of the construction site is obtained, the third monitoring video being obtained by a camera fixedly arranged in the construction site or a camera arranged on a mobile device;

[0067] Dynamic information and static information of construction personnel and construction vehicles in the construction site are determined according to the third monitoring video, and the first person-vehicle BIM model is constructed according to the dynamic information and the static information.

[0068] In this embodiment, a third monitoring video of the construction site can be obtained by a fixed camera arranged in the construction site or a mobile inspection device (such as an inspection vehicle or an inspection unmanned aerial vehicle). The static information and dynamic information of the construction personnel and the construction vehicles can be obtained from the third monitoring video. The static information is, for example, the clothing of the construction personnel, the type / color / specification size of the construction vehicles, etc. The dynamic information mainly refers to the motion data of the construction personnel and the construction vehicles, such as speed, direction, position, etc. According to the obtained dynamic information and static information, the first person-vehicle BIM model described above can be constructed.

[0069] Optionally, the second monitoring video associated with the target building under construction failure and the target material under construction failure is obtained, comprising:

[0070] Each associated area associated with the target building under construction failure and the target material under construction failure in the construction site is identified; wherein each associated area corresponding to the target building under construction failure is a material stacking area, and each associated area of the target material under construction failure is a building area.

[0071] A second monitoring video in each of the associated areas is obtained.

[0072] In this embodiment, the correspondence between the building and the building material is dynamic, that is, as the construction process of the building is constantly advancing, the building material gradually decreases or is updated, as the building material gradually decreases or is updated, the construction process of the building is constantly advancing. Therefore, when the construction fails the target building, the associated material area corresponding to the target building is obtained, and when the construction fails the target material, the associated building area corresponding to the target material storage area is obtained. Further, the second monitoring video captured by the camera arranged in the associated area, wherein the video duration of the second monitoring video is adjustable, which will be described in detail later.

[0073] Among them, the building material storage area used for the construction of the target building is pre-specified, the building supplied by each building material storage area is pre-specified, and the correspondence between the building and the target material storage area can be pre-set.

[0074] Optionally, the predicted real-time data of the target building and the target material is inferred from the second monitoring video, comprising:

[0075] The material dynamic characteristics and the building dynamic characteristics are obtained from the second monitoring video, and the predicted real-time data of the target building and the target material is inferred from the material dynamic characteristics and the building dynamic characteristics, respectively.

[0076] In this embodiment, after obtaining the second monitoring video, the material dynamic characteristics and the building dynamic characteristics can be obtained therefrom. Among them, the material dynamic characteristics refer to the total amount of material used displayed in the second monitoring video, and the building dynamic characteristics refer to the construction progress of the target building displayed in the second monitoring video. Based on the total amount of material used, the construction progress of the target building can be inferred, and based on the construction progress of the target building, the total amount of material used can also be inferred, and then the predicted real-time data of the target building or the target material can be obtained, and then the second building BIM model or the second material BIM model of the construction failure can be constructed based on the predicted real-time data.

[0077] Optionally, the video duration of the second monitoring video is determined by the following method:

[0078] The first number of the associated area associated with the target building of the construction failure is obtained, and the second number of the associated area associated with the target material of the construction failure is obtained, and the video duration of the second monitoring video is determined based on the first number and the second number, respectively; wherein the video duration of the second monitoring video is positively correlated with the first number and the second number.

[0079] In this embodiment, since one target building can take building materials from multiple building material storage areas, and one building material storage area can supply multiple buildings with building materials at the same time, the accuracy of the total amount of building materials used by the target building and the total amount of building materials supplied by the target building material storage area to the target building based on the analysis of the second monitoring video is insufficient. In order to improve the accuracy, the video duration of the second monitoring video is dynamically adjusted, that is:

[0080] The first number of associated areas (i.e., the number of building material storage areas) associated with the target building whose construction fails is obtained, and the second number of associated areas (i.e., the number of supplied buildings) associated with the target building whose construction fails is obtained. The video duration of the second monitoring video is determined based on the first number or the second number and the corresponding positive correlation. Thus, when the number of associated areas is greater, a longer duration of the second monitoring video is used to accurately analyze the total amount of building materials used by the target building, and to accurately calculate the construction progress of the target building; and the construction progress of each building that needs to take building materials from the target building material storage area is analyzed, and the total amount of building materials used in the target building material storage area is accurately calculated.

[0081] As shown in Figure 2 The embodiment of the present application also discloses a BIM-based construction monitoring system, which comprises a processor and a memory. The processor calls and executes a computer program in the memory to realize the following steps:

[0082] A basic BIM model of the construction site is constructed, and the basic BIM model comprises a first building BIM model, a first material BIM model and a first person / car BIM model;

[0084] The second building BIM model, the second material BIM model and the second person / car BIM model are used to replace the first building BIM model, the first material BIM model and the first person / car BIM model in the basic BIM model respectively, so as to obtain a dynamic BIM model of the construction site;

[0085] Further comprising:

[0086] If the second building BIM model of the target building and the second material BIM model of the target material fail to be built, second monitoring videos associated with the target building and the target material that fail to be built are acquired;

[0087] Predicted real-time data of the target building and the target material are inferred according to the second monitoring videos, and the second building BIM model and the second material BIM model are built according to the predicted real-time data.
