摘要
为了扩大航拍相机的有效视场,设计了基于数字信号处理器(DSP)的航测相机扫摆控制系统。利用该系统可实现相机在扫摆过程中的连续拍照。系统的主要功能是控制步进电机按拍摄速度和位置精度要求运动,其中步进电机的加减速采用梯形算法,能够较好的满足连续拍摄的要求。
The scanning control system of aerial film camera based on DSP to extend its effective field of view is introduced in this paper.It can photograph continuously when the camera works.The main function of system is to control step motors running within the demand of photograph speed and postion＇s precison.Trapezia method is employed for the acceleration/deceleration of step motors that can satisfy the system＇s demand.
