The elevational images could be obtained by resolving camera parameters and correcting digital images with numerical differential. Throughout image processing, the marks on the undercarriage wheels and airframe were high-accurately tracked and identified based on sub-pixel. The trace, velocity and other parameters of the undercarriage were gained by data processing.

同时，应用摄影测量原理，通过对摄影机的标校，获得了摄影机的参数；利用图像的数字微分纠正原理，对所摄图像进行修正和重建，得到摄影机的正摄影像，进而利用图像处理方法对起落架机轮及机身测量标志进行基于亚像素的跟踪判读；对判读数据进行处理，得到了飞机着陆道面段的运动轨迹、速度等数据。

Along with the booming development of the data service, much traditional phone servic blends with the function of data transmission in the different degree, where it is not exceptive for Data Cell Mobile Communications that regard GSM CDMA as primary technique.
