An Analysis of the Scanning Traces on the Earth in Airborne 3-D Information Acquisition
机载三维信息获取地面扫描轨迹分析

According to the general configuration of a scanning optical system for airborne 3-D information acquisition, the relation between the scanning trace of the sampled sites on the earth and the configuration parameters of the optical system is established and, the quantitative expression of the coordinates of the sampled sites on the earth is obtained. For some specific scanning traces, the selected methods and designed results of the configuration parameters of an optical system for terrain measurements are given.
