摘要
针对摄像机脚架难以准确自平衡的问题,设计了一种基于直线电机的全自动自伸缩平衡摄像机脚架。在摄像机脚架上增加自动伸缩收回机构并辅以配套的平衡模式,利用陀螺仪模块探测周围环境信息,采用加速度计矫正和卡尔曼滤波后,获得稳定的输出数值,实现对摄像机脚架机动模块运动的比例调节控制。实验结果表明,所设计的摄像机脚架可以通过自身的自平衡调节,准确停在目标位置,达到了全自动调整水平的设计目的,可为解决摄像机脚架水平调整问题提供解决方案。
In order to solve the problem of the difficulty of vidicon foot stool in accurate self-balancing,the paper has designed a kind of full-automatic flexible horizontal vidicon foot stool based on linear motor.Self-motion flexible organization in vidicon foot stool is added,and balancing model is equipped.It can use gyroscope model to explore environmental information around,obtain steady output numerical value after accelerometer correction and Kalman filtering,and achieve the regulation control of vicicon foot stool maneuvering model motorial proportion.The designed vidicon foot stool can accurately stop on the aimed location through self-balancing adjustment,achieve the design goal of full-automatic self-balancing adjustment,and provide solving scheme for horizontal self-balancing adjustment of vidicon foot stool.
