The Choice of DH-CG300 Image Acquisition Card Driver Methods and Real-time Image Acquisition in LABVIEW Platform
The drive of image acquisition card is the base of image acquisition and subsequent image processing on the im age acquisition plat form. Because LABVIEW does not support non-National Instruments card, So on the LABVIEW platform, if it needs to use a thirdparty card, it will need to prepare the drive of an independent card. This paper introduces the methods that how to call LABVIEW port operation icon, how to use Dynamic link library (Call Library Function) node, how to use code interface node (CIN), and how to use dynamic data exchange (Dynamic Date Exchange) technology to d rive DH-CG300 image acquisition card on the LABVIEW platform, and analyses and compares these methods objectively in program efficiency, accuracy of data acquisition, instantaneity, operability and functional scalability, and other aspects, and summarizes the technical characteristics of the above methods of the drive of DH-CG300 imageacquisition card, and gives the best choice method to drive DH-CG300 image acquisition card for real-time image acquisition, and completes the drive of DHCG300 image acquisition card. Meanwh ile based on the powerful LABVIEW development platform, combined with the DH-CG300 image acquisition card, and built lowcost, high efficiency, convenient and easy real-time continuous image acquisition system.
