胜利油区勘探决策支持系统需要处理和应用不同坐标系统下采集的数据,同时需要对扫描输入的图形进行校正处理,以便满足勘探论证的要求。从坐标变换的基础理论出发,对相同基准和不同基准下的坐标变换进行了研究,建立了坐标转换流程。提出了平面图形校正的4点法,并编写了相应的软件模块。在把虚拟坐标图件校正成可用的实际坐标图件,或普通位图格式图件的矢量化等方面有广泛应用。不但在实际应用过程中证明了该方法的正确性,而且在地质综合研究和勘探部署上具有很高的实用价值。
Shengli Oilfield Exploration Decision Support System needs to process and apply the data collected under different coordinate systems, and at the same time it needs to correct the graphics input by scan in order to meet the requirements of exploration demonstration. Based on the basic theory of coordinate transformation, the coordinate transformation under the same datum and different datum is studied, and the coordinate transformation process is established. The 4-point method of plane graph correction is proposed and the corresponding software module is compiled. In the virtual coordinates of the map can be used to correct the actual coordinates of the map, or ordinary bitmap format map of the vector has a wide range of applications. It not only proved the correctness of the method in practical application, but also has high practical value in the comprehensive geological research and exploration and deployment.
