Description

Technical Field

[0001] The present invention relates to the technical field of building construction progress monitoring, and in particular to a method and system for building construction progress monitoring based on image-model linkage. Background Art

[0002] The existing methods for monitoring the progress of construction on the market are diverse and are designed to meet the management needs of projects of different sizes and complexities. Manual on-site inspection: Experienced professionals go to the construction site in person to evaluate the construction progress by observation and recording. However, this method is limited by the observation ability and workload of the personnel, and its efficiency and accuracy are often difficult to be fully guaranteed. Submit progress reports regularly: The construction unit will submit detailed construction progress reports to the supervisor or the owner according to the established time nodes. These reports usually include information such as the amount of completed work, the remaining work, and possible progress deviations. However, since it takes a certain amount of time to collect and organize data, there may be data lags, and the authenticity of the report needs to be further verified. Project management software: Through digital means, the functions of preparing, tracking and analyzing the progress plan are realized, which greatly improves management efficiency. However, using project management software also requires a certain amount of learning and adaptation costs, especially for construction teams that lack relevant experience, they may need to invest more time and energy to master this tool. Video surveillance: By installing surveillance cameras at the construction site, real-time monitoring and video playback of the construction process can be achieved. However, video surveillance has limited coverage and requires a lot of equipment and manpower costs for maintenance and management. Construction deviations and process errors: Construction workers rely on paper drawings and manual records, which are prone to misunderstandings. This leads to rework and additional costs. Insufficient risk early warning capabilities: Traditional project management methods lack predictive management of project risks. As a result, when the project is delayed or has other problems, the best time to deal with it has often been missed. Summary of the invention

[0003] The present invention solves the problem that the existing construction progress monitoring is overly dependent on manual labor and lacks risk warning capabilities. A construction progress monitoring method and system based on drawing-model linkage is proposed to realize the association of drawings, models, and plans, and achieve the effect of visual display and simulation of plans. At the same time, drones are used to collect construction site data at set points and automatically analyze project delay risks, so that early warning notifications can be sent in a timely manner to improve risk warning capabilities.

The construction progress monitoring method based on image-model linkage according to claim 1 is characterized in that: The S3 specifically includes the following steps: combining the building requirements in the electronic construction drawing with the construction progress, and using visualization means to display the construction progress and on-site changes in the digital three-dimensional model of the building.

5. The construction progress monitoring method based on image-model linkage according to claim 4 is characterized in that: The visualization means includes changing the color or adjusting the transparency of the digital three-dimensional model components of the building.

6. A construction progress monitoring method based on image-model linkage according to any one of claims 1 to 5, characterized in that: The construction progress data is collected by drones at monitoring points.

7. The construction progress monitoring method based on image-model linkage according to claim 1 is characterized in that: The S4 specifically includes the following steps: the dynamic detection network determines whether the construction progress is on schedule, if so, continuously collects data; if not, determines whether there is a risk of delay in the construction progress, if so, issues a delay warning, if not, issues an overdue warning.

8. The construction progress monitoring method based on image-model linkage according to claim 7 is characterized in that: The delay warning includes the delay type, the scope of delay impact and the response measures.

9. The construction progress monitoring method based on image-model linkage according to claim 8 is characterized in that: The dynamic detection network makes judgments based on the comparison of the construction progress data with the planned construction progress. When the construction progress data is consistent with the planned construction progress, the construction progress is on schedule; when the construction progress data lags behind the planned construction progress, there is a risk of delay.

10. A construction progress monitoring system based on image-model linkage, using a construction progress monitoring method based on image-model linkage as claimed in any one of claims 1 to 5, characterized in that: The system comprises a central control module and a database, wherein the database stores electronic construction drawings, digital three-dimensional models of buildings and construction plans, the central control module is provided with a drawing-model linkage mechanism, and the drawing-model linkage mechanism associates the electronic construction drawings and the digital three-dimensional models of buildings according to the construction plan, the central control module is electrically connected to a dynamic detection network, a display module and a plurality of drones, the drones acquire construction progress data at set detection points, output detection results to the display module after analysis by the dynamic detection network, and the detection results are visualized by the display module.
