return winform;调用halcon的摄像头进行连续处理，记得要释放掉Obj内存，要不然内存会慢慢增加到溢出为止。。。。。。。。
注意：
经过多次测试，发现个问题，开启halcon摄像头必须按照一定的顺序初始化，要不然得出的效果就不是正常的。
开启摄像头显示必须按照下面的格式顺序：
var AcqHandle = HOperatorSetX.OpenFramegrabber( 'DirectShow', 1, 1, 0, 0, 0, 0, 'default', 8, 'rgb', -1, 'false', 'default', '', 0, -1 ); HOperatorSetX.GrabImageStart( AcqHandle , -1 ); var Image = HOperatorSetX.GrabImageAsync( AcqHandle , -1 ); //调整画面大小和图像一致 var WindowHandle = HOperatorSetX.OpenWindow( 0 , 0 , winform.picturebox.width, winform.picturebox.height , winform.picturebox.hwnd , "transparent","" );
先初始化摄像头，然后开启摄像头，然后获取一帧图像舍弃，再初始化界面中的图像控件。。。
其他的任何顺序都会得不到想要的效果。

如果调用多个摄像头，必须开线程：
