利用四个已知控制点及其对应像点坐标解求六个外方位元素（即空间后方交会） (2009-04-24, Visual动态输入控制点个数，比例尺以及焦距和各个控制点的像点坐标和地面点坐标，确定航片的6个外方位元素-The use of four known control points and its corresponding image point coordinates solution seeking six elements of exterior orientation (ie, space resection) (2009-04-24, Visual Dynamic Input control points number, scale, and the focal length and the various control points, as point coordinates and ground point coordinates to determine the aerial photograph of the six exterior orientation elements

采用电流正弦波细分原理，研制出了一种三相混合式步进电机驱动器，实现了三相混合式步进电机的相电流闭环控制和细分驱动。具有多种细分和相电流设置功能，能够驱动多种三相混合式步进电机，其最小步距角为0.036°。-Breakdown of the use of sinusoidal current principle, developed a three-phase hybrid stepping motor driver, to achieve a three-phase hybrid stepping motor phase current breakdown of the closed-loop control and drive. With multiple segments and phase current setting function, able to drive a variety of three-phase hybrid stepping motor, the smallest step angle is 0.036 °.
