摘要
针对溜井全景扫描仪因扫描探头升降速度不稳定导致的图像模糊、变形和不连续等问题,在分析全景扫描仪升降装置结构的基础上,建立了扫描探头升降速度与转筒角速度之间的关系模型,以此作为设定转筒角速度曲线的理论依据,并采用防积分饱和的闭环PI控制方法实现扫描探头升降速度的恒定控制。实验及应用结果表明,该扫描探头升降速度控制方案实现了扫描探头恒速升降,所得图像清晰,无变形。
In order to solve image blurring,distortion and discontinuousness caused by unstable movement speed of scanning probe of panoramic scanner for draw shaft,structure of movement device of panoramic scanner was analyzed and relationship model between movement speed of scanning probe and angular speed of rotary drum was established,which was taken as theory evidence for setting angular speed of rotary drum.A closed-loop PI control method with anti-windup for integral was adopted to control movement speed of scanning probe.The experiment and application results show that the movement speed control strategy realizes movement with stable speed of scanning probe,and scanning images are clear and without distortion.
