摘要
论述了规则分布的二维网格点数据场中,使用追踪方式进行等值线分析的算法,通过完成点的属性标记法,提高了分析速度,保证了运行的稳定性,并且避免了累积记录法可能产生的错误;使用V isual B asic语言,实现了等值线分析范围的自动选择、分析步长设置,并利用B样条曲线,完成了对等值线线段的光滑处理,为提高自动化水平和工作效率提供了有力的软件支持.
Algorithm of contour analyzing with pursuit method in 2 dimension regular grid data field was discussed in this paper to meet the demand of engineering work. By marking analyzed points attributed,working speed and stability were improved and potential errors of accumulating record were avoided. A software was developed with Visual Basic to carry out the task of maximum and minimum auto selection and interval setting. The smooth process to contour was completed using B sample line also. The automatic level and efficiency were promoted by this software.
