| 摘 要： | 针对海量数据工程图在数字化过程中出现的误差较大、处理效率太低的问题，提出了一种基于格网的双线性变换算法结合双缓冲区存取数据技术的新方法，并对双线性变换算法进行了优化。最后将该方法应用于一种具体的海量数据工程图——飞机模线图，实现了对该类图快速、有效的几何校正。

| Abstract: | In order to eliminate the big deviation and raise working efficiency in the process of digitalization of engineering drawing possessing mass information, a new method combining the dual-linear transformation algorithm with the technology of dual-buffers reading/storing data is referred and the dual-linear transformation algorithm is optimized. Finally, during dealing with the aircraft master layout, which is a specific kind of engineering drawing possessing mass information, the new method is adopted and the result is accomplished rapidly and effectively. |
