摘要
煤矿井下巷道线均由井下布设的测量控制导线点数据计算所得,建立标准的测量数据格式,由井下控制点坐标、点距左帮、右帮已知数据,应用测量基础数据计算巷道边线以及巷道中线,由所计算的关键点自动由点绘制出井下巷道平面图。三维巷道通过平面图进行建模,单个巷道体建模技术已有很多种方式。对于巷道体间节点的连接以及三维面体的缝合需要进一步细化处理。三维巷道体的总体视觉效果在节点处的处理尤为重要。
Underground roadway lines were calculated from the measurement control wire point data laid underground in coal mine, standards of measurement data format were established, taking underground control point coordinates, pitch for the left and right as the known data, base data of the measurement were applied to calculate roadway lines and the center line of roadway,then underground roadway line was mapped out. Three-dimensional roadway was modeled by plane drawing. There were many ways for single roadway body modeling technology. The joints between roadways and the stitching of three-dimensional faces need to be further refined. The overall visual effect of three-dimensional roadway was particularly important in the processing of nodes.
