摘　　要：为了解决PCIE-1429采集卡不支持双相机同时进行数据采集的问题,通过LabVIEW搭建高速数据采集系统,由VC++生成具有解包功能的动态链接库,再利用LabVIEW对其进行调用,实现了双相机采集数据的实时解包。实验证明,该方案成功利用PCIE-1429采集卡在"双Base模式"下进行连续的数据采集,具有快速、有效、稳定、操作方便等优点。PCIE - 1429 acquisition card doesn＇t support data acquisition synchronously of tow cameras. To solve this problem, a high - speed data acquisition system based on LabVIEW is designed, the dynamic link library with function of data detaching by VC^-- is created,and LabVIEW is adopted to call the DLL,a data detaching scheme of double cameras acquisition is achieved. Experiment proves that continuous data acquisition with PCIE - 1429 acquisition card under ＂double - base mode＂, And it has advantages of expeditious, effective, stable and operating expediently.
