Construction Progress Control Method of Sluice Pier Based on BIM and Computer Vision Technology
The construction schedule of water conservancy project not only affects the construction cost,but also may affect the safety of the project due to the flood.Based on BIM technology and image recognition technology,a virtual and real combination of gate pier pouring height recognition method was proposed.The BIM technology was used to establish the virtual model of gate pier,and virtual image data sets of different pouring heights of gate pier could be obtained.The improved deep learning algorithm Vision Transformers was used to train and learn the virtual data set of the pouring height of gate pier,and the recognition model that can identify the pouring height of gate pier was obtained.The real model of gate pier was established in the laboratory to simulate different pouring heights of gate pier.The camera was used to obtain the real images of different pouring heights of gate pier,and the trained recognition model was used to veri-fy the real images.The results show that the model can accurately identify the pouring height of the gate pier real image.This method can be applied to the real construction progress identification of the main structure of hydraulic engineering,and can also provide support for the construction of digital twin hydraulic engineering.
