摘　　要：常规GIS煤矿地质勘查系统在生成图像生成过程中会丢失地物特征,导致系统成像边界不清晰,因此设计了基于计算机图像的煤矿地质勘查系统。系统的硬件优化中,主要对数字相机的相关参数进行校验,通过修正方程得出相机标称焦距、畸变补偿等重要参数的最优值;软件优化中,将复杂的煤矿地质体视为类三棱柱进行剖切,保证得到的地质数据更加精确,设计剖切流程,采用完全剖分法确定剖分点;处理剖切得到的多边形区域,删除悬挂标志物,完成纹理贴图,至此完成煤矿地质勘查系统设计。实例分析结果表明,设计的系统最终成像清晰,具体描述了矿区地物细节,并且区域之间界线明显,可以直观看出矿区情况。Conventional GIS coal mine geological exploration system will lose ground features in the process of generating images,resulting in unclear imaging boundaries of the system.Therefore,a coal mine geological exploration system based on computer images was designed.In the hardware optimization of the system,the relevant parameters of the digital camera were mainly verified,and the optimal values of the camera′s nominal focal length,distortion compensation and other important parameters were obtained through the correction equation;in the software optimization,the complex coal mine geological body was regarded as a class,the triangular prism was cut to ensure that the obtained geological data was more accurate,the cutting process was designed,and the complete division method was used to determine the division points;the polygonal area obtained by cutting was processed,the hanging markers wee deleted,and the texture map was completed.The results of the case analysis showed that the final image of the designed system was clear,and the details of the mining area were described in detail,and the boundaries between the areas were obvious,and the situation of the mining area could be seen intuitively.
