[0023] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0024] like Figure 1 As shown, an embodiment of the present invention discloses a construction monitoring method based on BIM, and the method comprises the following steps: Constructing a basic BIM model of the construction site, wherein the basic BIM model includes a first building BIM model, a first material BIM model, and a first person-vehicle BIM model; Acquire monitoring data of a monitoring system of a construction site, wherein the monitoring data includes a first monitoring video and first material electronic information, and construct a second building BIM model, a second material BIM model, and a second person-vehicle BIM model according to the first monitoring video and the first material electronic information; Use the second building BIM model, the second material BIM model, and the second person-vehicle BIM model 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 as to obtain a dynamic BIM model of the construction site; The method further comprises: If the second building BIM model of the target building and the second material BIM model of the target material fail to be constructed, obtaining a second monitoring video associated with the target building that failed to be constructed and the target material that failed to be constructed; Predicted real-time data of the target building and the target material are inferred based on the second monitoring video, and the second building BIM model and the second material BIM model are correspondingly constructed based on the predicted real-time data.

[0025] The present invention first constructs a basic BIM model of the construction site, which includes a building BIM model, a material BIM model, and a person-vehicle BIM model, which respectively correspond to the buildings on the construction site, the building materials (such as sand, gravel, cement, steel bars, etc.) in the storage yard, the construction personnel, and the construction vehicles.

[0026] Then, during the construction process of the construction site, the first monitoring data of the monitoring system of the construction site is obtained in real time. The monitoring system includes a video monitoring system and a material electronic management system, so that the first monitoring video and the first material electronic information can be obtained respectively. According to the monitoring video, the real-time internal and external structural data of each building in the construction site can be extracted, and then the latest second building BIM model can be constructed; according to the monitoring video and the material electronic management system, the real-time situation of the building materials in the storage yard can be comprehensively determined, and then the second material BIM model of the building materials can be constructed; according to the monitoring video, the dynamic and static information (such as position, speed, etc.) of the construction personnel and construction vehicles active in the construction site can also be extracted, so that the second person-vehicle BIM model can be constructed.

[0027] Finally, the second building BIM model, the second material BIM model, and the second person-vehicle BIM model obtained above are replaced to the corresponding positions in the basic BIM model, that is, the basic BIM model is updated, thereby obtaining a dynamic BIM model of the construction site.

[0028] Affected by various factors (such as damage to cameras in an area), the video surveillance system cannot fully cover all areas of the construction site, resulting in failure to update the BIM model of some BIM objects, such as failure to build a second building BIM model of the target building or a second material BIM model of the target material. To address this problem, the present invention also provides the following processing methods, specifically: The second monitoring video associated with the target building that failed to be constructed and the target material that failed to be constructed is obtained. The second monitoring video obtained here is, for example, the monitoring video of each associated area that has an associated relationship 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, and the second building BIM model of the target building and the second material BIM model of the target material are correspondingly constructed according to the predicted real-time data. Thereby, the successful update of the BIM model is achieved in the case of missing monitoring video.

[0029] Therefore, the solution of the present invention can automatically build 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 solution of the present invention can also effectively deal with the update of the BIM model in the case of missing monitoring video, ensuring that the BIM model of the construction site can always keep the latest dynamics.

[0030] Optionally, constructing a basic BIM model of the construction site includes: receiving or accessing electronic planning drawings containing construction site planning information by electronic means, the electronic planning drawings containing information about planning details of various areas of the construction site; Analyzing and processing the electronic planning drawings using computer algorithms and / or software tools to extract building planning information about various areas of the construction site, including but not limited to the location, size, structure type, material specifications of the building, and the functional division of each area; According to the extracted building planning information, a basic BIM model of the construction site is constructed using BIM modeling software, wherein the basic BIM model includes a first building BIM model and a first material BIM model.

[0031] In this embodiment, the above-mentioned basic BIM model includes a detailed three-dimensional representation of each area of ​​the construction site, namely, a plurality of first building BIM models and first material BIM models.

[0032] 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 the fields of architecture, structure, and electromechanical, providing comprehensive modeling and design functions. Bentley OpenRoads: Focuses on road design, suitable for civil engineers, and provides powerful road modeling and analysis tools. Graphisoft ArchiCAD: Provides architects with a flexible design environment that emphasizes creativity and design freedom.

[0033] Optionally, constructing a basic BIM model of the construction site further includes: Acquire a third monitoring video of the construction site, where the third monitoring video is captured by a camera fixedly installed in the construction site or a camera installed on a mobile device; 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.

[0034] In this embodiment, a third monitoring video of the construction site can be shot by a fixed camera arranged in the construction site or by a mobile inspection device (such as an inspection vehicle or an inspection drone), and static information and dynamic information of the construction personnel and construction vehicles can be extracted from the third monitoring video. Static information includes, for example, the clothing of the construction personnel, the type / color / specification and size of the construction vehicle, and the dynamic information mainly refers to the movement data of the construction personnel and construction vehicles, such as speed, direction, position, etc. The above-mentioned first person-vehicle BIM model can be constructed based on the obtained dynamic information and static information.

[0035] Optionally, the acquiring of a second monitoring video associated with the target building that failed to be constructed and the target material that failed to be constructed includes: Identify each associated area in the construction site that is associated with the target building that failed to be constructed and the target material that failed to be constructed; wherein each associated area corresponding to the target building that failed to be constructed is a material stacking area, and each associated area of ​​the target material that failed to be constructed is a building area; A second surveillance video within each of the associated areas is obtained.

[0036] In this embodiment, the correspondence between the building and the building materials is dynamic, that is, as the construction process of the building progresses, the building materials gradually decrease or are updated, and as the building materials gradually decrease or are updated, the construction process of the building progresses. Therefore, when the target building fails to be constructed, the associated material areas corresponding to the target building are obtained, and when the target material fails to be constructed, the associated building areas corresponding to the stacking areas of the target material are obtained. Then, the second monitoring video captured by the camera deployed in each associated area, wherein the video duration of the second monitoring video is adjustable, will be described in detail later.

[0037] Among them, the building material stacking area used for the construction of the target building is pre-designated, and the building supplied by each building material stacking area is also pre-designated, and then the corresponding relationship between the building and the stacking area of ​​the target material can be preset.

[0038] Optionally, the predicting real-time data of the target building and the target material based on the second monitoring video includes: The dynamic characteristics of materials and buildings are extracted based on the second monitoring video, and the predicted real-time data of the target building and the target material are inferred based on the dynamic characteristics of materials and the dynamic characteristics of buildings.

[0039] In this embodiment, after obtaining the second monitoring video, the dynamic characteristics of materials and the dynamic characteristics of buildings can be extracted therefrom. The dynamic characteristics of materials refer to the total amount of materials used as shown in the second monitoring video, and the dynamic characteristics of buildings refer to the construction progress of the target building shown in the second monitoring video. The construction progress of the target building can be inferred based on the total amount of materials used, and the total amount of materials used can also be inferred based on the construction progress of the target building, 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 that failed to be constructed can be constructed based on the predicted real-time data.

[0040] Optionally, the video duration of the second surveillance video is determined by: Obtain a first quantity of each associated area associated with the target building that has failed to be constructed, obtain a second quantity of each associated area associated with the target material that has failed to be constructed, and determine the video duration of the second monitoring video based on the first quantity and the second quantity, respectively; wherein the video duration of the second monitoring video is positively correlated with the first quantity and the second quantity.

[0041] In this embodiment, since a target building may retrieve building materials from multiple building material storage areas, and a building material storage area may also supply materials for multiple buildings at the same time, the accuracy of the total amount of materials used by the target building and the total amount of materials supplied to the target building by the target building material storage area obtained based on the analysis of the second monitoring video is insufficient. In order to improve the accuracy, the present invention is configured to dynamically adjust the video duration of the second monitoring video, that is: The first number of associated areas associated with the target building that failed to be constructed (i.e., the number of construction material storage areas) is obtained, and the second number of associated areas associated with the target material that failed to be constructed (i.e., the number of buildings supplied) is obtained, and the video duration of the second monitoring video is determined based on the first number or the second number and the corresponding positive correlation. Therefore, when the number of associated areas is greater, a second monitoring video with a longer duration is set to accurately analyze how much construction materials are used in the target building in total, and then accurately calculate the progress of the construction of the target building; and the progress of the construction of each building that needs to retrieve materials from the material storage area of ​​the target building is analyzed, and then the total amount of materials used in the material storage area of ​​the target building is accurately calculated.

[0042] like Figure 2 As shown, an embodiment of the present invention further discloses a BIM-based construction monitoring system, including a processor and a memory, wherein the processor calls and executes a computer program in the memory to implement the following steps: Constructing a basic BIM model of the construction site, wherein the basic BIM model includes a first building BIM model, a first material BIM model, and a first person-vehicle BIM model; Acquire monitoring data of a monitoring system of a construction site, wherein the monitoring data includes a first monitoring video and first material electronic information, and construct a second building BIM model, a second material BIM model, and a second person-vehicle BIM model according to the first monitoring video and the first material electronic information; Use the second building BIM model, the second material BIM model, and the second person-vehicle BIM model 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 as to obtain a dynamic BIM model of the construction site; Also includes: If the second building BIM model of the target building and the second material BIM model of the target material fail to be constructed, obtaining a second monitoring video associated with the target building that failed to be constructed and the target material that failed to be constructed; Predicted real-time data of the target building and the target material are inferred based on the second monitoring video, and the second building BIM model and the second material BIM model are correspondingly constructed based on the predicted real-time data.
