| 摘 要： | 在疲劳裂纹扩展试验中,疲劳裂纹的自动跟踪是十分必要的.针对疲劳裂纹自动跟踪的问题,首先建立起了以步进电机为运动机构的摄像头云台系统,使用ARM作为步进电机控制器,然后由PC机对摄像头采集到的裂纹图像进行图像处理并转化为电机运动控制信号,最后将控制信号通过串口传送到ARM中.研究结果表明,摄像头运动系统定位精度为0.05...

| Abstract: | It is necessary to track fatigue crack automatically in the fatigue test.Aiming at the automatic tracking of the fatigue crack,firstly,a tilt system of camera was set up by stepping motor for sports organizations,and ARM was used as a stepping motor controller,then the crack image which was acquired by the camera was processed by the PC and translated into motion control signal of stepping motor,finally the control signal was transmitted to ARM through a serial port.The results indicate that the camera's mo... |
