说明：  本程序通过DLL方式驱动相机，支持相机的所有属性，包含触发、白平衡等参数。另外大恒水星系列工业相机还支持GENICAM协议，因此可以通过DirecX协议，直接通过NI的IMAQdx驱动程序进行驱动。但是这种方式，部分属性无法设置，如触发、白平行等。因此，如果相机只是用于演示、实验，则可以直接用NI视觉软件进行操作，或者用于VBAI中也可以；如果是需要自己通过LabVIEW编写程序，则建议使用DLL方式进行驱动，这样可以灵活的设置各种参数，高速稳
(This program drives the camera by DLL mode, supports all attributes of the camera, including trigger, white balance and other parameters. In addition, the large star Mercury series industrial cameras also support GENICAM protocol, so they can be driven directly through NI's IMAQdx driver through DirecX protocol. But in this way, some attributes can not be set, such as trigger, white parallel, etc. Therefore, if the camera is only used for demonstration and experiment, it can be operated directly with NI visual software or in VBAI; if you need to write your own program through LabVIEW, it is recommended to use DLL mode to drive, so as to set various parameters flexibly, high speed and stability.)
