Research On Modeling Method Of Coal Mine Tunnel Based On Sketch Input

In recent years,the digital construction of mines has greatly accelerated social and economic development.The main work of the mine informatization process is to establish a digital mine system,and the coal mine tunnel is an important part of the mine system.Simple and fast tunnel modeling methods will make the development of digital mine engineering easier,the development cycle of digital mine engineering quicker,and the cost of mine information engineering lower.Based on the previous research,this paper studies the modeling of coal mine tunnels based on hand-drawn sketches,including the following main tasks:1.It studied the deformable convolution kernel,including its advantages and disadvantages in coal mine tunnel cross-section identification.The fixed convolution kernel in ResNet18 is replaced with a deformable convolution kernel to enhance the modeling ability of the model for hand-drawn strokes.The advantage is proved through comparative experiments.2.It studied the de-earing triangulation,including its advantages and disadvantages in the process of roadway cross-section generation.The de-earing idea is used in the triangulation method of tunnel modeling to improve the triangulation efficiency.It proved the idea through comparative experiments.3.Designed and implemented a coal mine tunnel model generation system based on sketch input.The system has the function of generating coal mine tunnel models based on user cross-sectional profile input and scan line input.It tested the system and analyzed the possible deficiencies in the study.
