波浪式抖动

qiangkai311 · 发表于 2013-3-13 14:42:20

哪位大神帮忙看看我用的s12+COMS采集的图像发到上位机有波浪式的抖动，这是车不动时截的图片，这种情况属于正常吗？怎样才能改进？谢谢各位大侠指导

中间是不是丢了若干行？

中间是不是丢了若干行？

不应该啊！就采集了40行，前六行没有采集，采集从第七行开始每个五行采集一行
interrupt 8 void HREF_Count(void)
{
  TFLG1_C0F = 1;
  m++;
  if ( m<6 || m>200 )
  {
return;//判断是否从新的一场开始
  }

  Interval=5;
  if(m%Interval==0)
  {
_asm(nop);
      // _asm(nop);
      //_asm(nop);
      //_asm(nop);
   //delays(8);

Image_Data[Line_C][129] = PORTA;
Line_C++;
  }

}
如果每六行采集一样的话会有错位和抖动，所以就改为每五行采集一样，大侠麻烦帮出出主意，小弟谢啦！

你说的是不是一行一行刷新下来。。由远到近，每一幅图都跟比前一幅图有一定位移？场中断没搞吧？

大神你说的太对了，就是那样的，场中断有啊！判断场中断采集够一场数据才发给上位机，至于这个场中断进去了没就不明确了，还望指教啊！怎么做可以避免这样的问题发生？谢谢啦！不胜感激啊！

我想都是你可以自己解决的问题，问题还有可能出在和串口的通讯上，先猜想再一一排除咯，祝你成功~

非常谢谢你！问题出在行场中断的开关时间上，我把开关中断的时序调整了下，图像比以前就稳定的多了，嘿嘿。。。。
