[0033] Please refer to Figure 1 , the BIM-based construction progress monitoring method provided by the present invention includes the following steps:

[0034] S1. Obtain picture information of the construction site, where the picture information includes first position information and time information.

[0035] It can be understood that the above steps may further include:

[0036] S101. Set the picture information acquisition period and acquisition angle.

[0037] It can be understood that the acquisition period can be to obtain photo information regularly, and the acquisition angle can be fixed, that is, the angle is the same every time photo information is obtained, or different acquisition angles correspond to the acquisition order.

[0038] S102, regularly obtain the picture information of the construction site according to the set period and acquisition angle.

[0039] It can be understood that the acquisition of picture information can be obtained through a camera, and the focal length of the acquired picture information can also be set as needed. The acquired picture will be marked with time information and the first position information, and the first position information can be the self-position information of the camera, and the coordinates of the self-position information can be determined with reference to a certain reference point in the construction area.

[0040] S2, obtain the corresponding node information according to the picture information, where the node information includes the second position information, several node progress information, and the model cross-sectional image.

[0041] It can be understood that the node progress information can include the corresponding characteristic information within a certain time point. The characteristic information can be some characteristic information of chandeliers and pipeline characteristics in building construction, etc. The model cross-sectional image can be obtained by cross-sectioning the complete construction model, and the cross-sectioning can be realized through known software. The model cross-sectional image includes the characteristics of all items that should be in the construction area after construction is completed, and the second position information is the position information of the corresponding complete construction model.

[0042] The above steps can further include:

[0043] S201, search for the corresponding second position information according to the first position information.

[0044] It can be understood that the corresponding second position information should be consistent with the first position information. When the position information is consistent, it is considered that the node progress information corresponds to the picture information. The search can be carried out in the form of keywords, and the searched node information can include multiple items. The node information with the same second position information has different corresponding node progress information.

[0045] S202, when the first position information is consistent with the second position information, select the node information corresponding to the second position information.

[0046] It can be understood that when selecting node information, it is necessary to select according to the time information in the picture information, and select the node progress information that is consistent with it according to the time information. The node progress information requires the time point to be consistent with the time information.

[0047] S3, obtain the construction progress status according to the picture information and the node information.

[0048] It can be understood that the above steps may further include:

[0049] S301. Obtain the corresponding node progress information from the node information according to the time information.

[0050] It can be understood that the node progress information consistent with the time information is selected.

[0051] S302. Match the picture information with the cross-sectional image of the model.

[0052] S302a. Obtain the contour features of the picture information.

[0053] It can be understood that the acquisition of the contour features can be achieved by using known algorithms.

[0054] S302b. Match the contour features with the cross-sectional image of the model to obtain a matching result.

[0055] It can be known that the matching can be understood as corresponding the features on the cross-sectional image of the model according to the contour features, so as to know which features on the cross-sectional image of the model the contour features correspond to, and then output the matching result.

[0056] S303. Compare the matching result with the node progress information to obtain the construction progress status.

[0057] It can be known that the above steps may further include:

[0058] S303a. If the matching result is consistent with the node progress information, then output that the construction progress requirements are met.

[0059] It can be understood that if the features in the image information of the matching result are consistent with the features in the node progress information, it is considered that the set construction progress has been achieved.

[0060] S303b. If the matching result is inconsistent with the node progress information and the matching result is greater than the node progress information, then output that the construction progress has been exceeded.

[0061] It can be understood that the construction sequence is fixed. Therefore, it can be considered that workers will not skip some steps during the construction process. Therefore, in the case where the node progress information is inconsistent with the matching result, there is no problem that workers skip the corresponding steps. Therefore, as long as the feature information in the matching result is more than the feature information in the node progress information, it can be considered that the construction progress has been exceeded.

[0062] S303c. If the matching result is less than the node progress information, then output that the construction progress requirements are not met.

[0063] It can be understood that when the feature information in the matching result is less than the feature information in the node progress information, it is considered that the construction progress requirements are not met.

[0064] After obtaining the construction progress result, a progress schedule can also be generated, and the construction progress can be supervised according to the progress schedule.

[0065] From the above description, it can be known that the BIM-based construction progress monitoring method provided by the present invention can utilize the monitoring cameras at the construction site to obtain the image information of the construction site, and monitor the construction progress in combination with the node information, improving the utilization rate of the monitoring cameras, saving manpower, and at the same time, the overall monitoring accuracy is high.

[0066] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
