| 摘 要： | 为了改善巷道三维建模算法中特殊交岔点不能相互贯通的缺点，研究基于布尔运算的巷道交岔点建模算法，以实现巷道各类交岔点的相互贯通。根据实测导线数据、断面参数及巷道属性信息，采用六元组统一方法表示断面形状，实现巷道交岔点及各断面形状的连接。实验结果表明，基于布尔运算算法的垂直巷道交岔点建模算法贯通率达到100%。该算法不仅实现了巷道交岔点的相互贯通，而且能有效修正巷道设计中存在的误差，提高巷道三维模型精度。

| Abstract: | For improving the disadvantage in the 3D roadway modeling algorithm which special intersection points do not penetrate each other， this article studies the modeling algorithm of roadway intersection points based on Boolean operation. All kinds of intersection points of roadway are interconnected. According to the measured traverse data， section parameters of each section of roadway and roadway attribute information， a unified method of six tuples represents the sectional shapes and the algorithm automatically deals with the intersection point of roadway and the connection of the shape of each section. Experiment results have shown that the modeling algorithm of vertical roadway intersection points based on Boolean operation algorithm has higher penetration. The study realizes the interlinking of roadway intersection points， and can correct the error in the roadway design effectively and improve the accuracy of the three-dimensional roadway model. |
