| 摘 要： | 与传统的摄影调焦系统相比较,针对焦距可以灵活调整的要求,提出了基于TMS320F240控制步进电机调焦的设计方案,利用F240控制电机驱动器UP-4HB03M按照计算所得的调焦轨迹进行调焦。实验结果表明,本系统调焦曲线与理想曲线拟合度较好,拍摄已知运动轨迹的目标,达到了满意效果。

| Abstract: | Some traditional adjustment of focus photography sys- tems are compared. According to the requirement of flexible ad- justment, a scheme of adjusting focus based on TMS320F240 by controlling step motor is presented. The focus is adjusted accord- ing to the curve, which has been calculated already. Finally the result given by experiment shows that the curve of adjusting fo- cus is fit well with the ideal curve. Shooting the goal of the known movement orbit has reached the satisfactory result. |
